Their structures were verified by 1H NMR, 13C NMR, HRMS and single X-ray crystal diffraction analysis. Most of the target products exhibited medium to excellent antifungal activity against 6 phytopathogenic fungi in vitro at a concentration of 50 mg/L. Interestingly, compounds A13 and A25 with EC50 values of 2.375, 2.251 mg/L s against A. alternate, that were similar to boscalid (EC50 = 1.195 mg/L). The in vivo experiments revealed that A13 presented 51.61% and 70.97% protection activities against A. alternate at the dosage of 50 and 100 mg/L, respectively, which were equal to that of boscalid (64.52% and 77.42%). The SEM analysis indicated that compound A13 could strongly damage the mycelium morphology. Molecular electrostatic potential and molecular docking analysis revealed that A13 was covered by negative potential contour, and strongly interacts with the residues of SDH. These results revealed that compounds A13 and A25 could be as promising antifungal candidates for the development of natural-based fungicides. 1-Arylisoquinoline Biomimetic design Antifungal activity Antifungal mechanism Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Introduction Phytopathogenic fungi are causing substantial harm to grain crops, resulting in diminished yield, compromised quality, and ultimately posing a threat to the worldwide food security [ 1 ]. Although, chemical fungicides remain as the most effective and economical method for the control of fungal diseases at present [ 2 ], with the prolonged and massive irrational of traditiona-chemicals have caused resistance, residual toxicity and even environmental problems [ 3 – 4 ]. Therefore, it was urgent to discover and develop novel biocompatibility antifungal agents to control plant diseases and ensure the agricultural production safety. The natural-based or -derived compounds have attracted increasing attention as potential candidates to develop “green” agrochemicals due to their extensive biological properties, multiple modes of action and environment friendly [ 5 ]. Tetrahydroisoquinoline alkaloids (THIQs) are a kind of natural products with a common tetrahydroisoquinoline motif and widely exist in the Papaveraceae family and some members of the Rutaceae family [ 6 – 7 ]. THIQs and their derivatives exhibit antibacterial, antitumor, antimalarial, anti-inflammatory, and influence on the activities of various important biological enzymes [ 8 – 10 ]. Tiwari et al. synthesised a series of 1-aryl tetrahydroisoquinoline derivatives with antibacterial activity [ 11 ]. Amide is an important classic structural motif in agrochemicals and natural products, often serving as a linking bridge to introduce active pharmacophores for the development of novel pesticides [ 12 ]. Valine carbamate fungicides, categorized as amino acid fungicides, feature a double amide bridge chain in their structure, which provides good environmental compatibility [ 13 ]. Succinate dehydrogenase inhibitors (SDHIs) have become the most rapidly growing type of agrochemical due to their powerful and broad-spectrum antifungal activities, which damaging the citric acid cycle and respiratory chain electron transmission in fungal mitochondria [ 14 – 16 ]. The structure of commercial SDHIs typically consists of three components: a polar segment, a hydrophobic tail, and an amide bridge that binds them together. The pyrazole ring is the most commonly used polar segment, which often beneficial in enhancing the antifungal action of bioactive carboxamide derivatives [ 17 – 19 ]. In our previous work, several isoquinoline compounds were designed and synthesized with antifungal activites [ 20 – 21 ]. In order to further study isoquinoline derivatives and find novel active fungicidal candicates. A series of novel 1-arylisoquinoline derivatives were designed and synthesized, which introduce double amide bridge binds tetrahydroisoquinoline motif and polar core together (Fig. 1 ). Their antifungal activities against six plant pathogenic fungi were studied. Compound A13 with excellent fungicidal activity was further tested in vivo to against A. alternata on fragrant pears. In addition, scanning electron microscopy (SEM) observations, molecular electrostatic potential. and molecular docking analysis were conducted. Results and Discussion Chemistry The synthetic route of the target compounds as shown in Scheme 1 . 2-(3′,4′-Dimethoxypheny1)ethy1amine 1 reacts with appropriate aldehydes 2a-2h in anhydrous toluene to form the schiff bases 3a-3h . The intermediates 4a-4h were obtained by intramolecular cyclization of 3 with trifluoroacetic acid. Then, 4a-4h was condensed with Boc-glycine to obtain intermediates 5a-5h . Under acidic conditions, the Boc protective group was removed to obtain intermediates 6a-6h , and then condensed with heterocyclic aryl chlorides 7a-7d to obtain target compound A1-A32 . The structures of the title compounds were identified by 1 H NMR, 13 C NMR, HRMS and single-crystal Xray diffraction. As in A5 , the 1 H NMR spectrum of compound A5 at room temperature showed that the proton signals of the methylene groups at C3 and C4, the methoxy groups at C6 and C7, and most of the carbon atoms on the aromatic ring were splitted. It indicated this type of compounds exhibit steric isomerism, resulting in the splitting of proton signals at room temperature. The variable temperature nuclear magnetic resonance test results showed that as the temperature increased to 120 o C, the splitted signals gradually converged to a single signal (Fig. 2 ). The structure of A5 was further identified by X-ray diffraction (Fig. 3 ). Based on the above details, the target compounds were confirmed as pure substance. Antifungal activity The in vitro antifungal activities of target compound A1-A32 against six kinds of phytopathogenic fungi at a concentration of 50 mg/L were shown in Table 1 . As the data showed, all the target compounds showed varying degrees of inhibition against the tested fungi. For R. cerealis , compounds A30 , A31 , and A32 exceeded more than 70% antifungal activities, which superior to the positive control boscalid (6.23%). Compound A25 has an inhibitory rate of 67.25% against the P. piricola , it is comparable to the boscalid (66.56%), but lower than chlorothalonil (88.69%). In particular, compounds A5 , A9 , A13 , A21 , A25 , A28 , and A32 all have over 70% inhibitory rates against A. alternata. Among them, A13 (90.81%) and A25 (94.13%) were comparable to boscalid (92.13%), and better than chlorothalonil (37.79%). Furthermore, the EC 50 value of A13 (2.375 mg/L) and A25 (2.251 mg/L) against A. alternate was equivalent to the positive control boscalid (1.195 mg/L) (Table 2 ). In compare with boscalid, compounds A13 and A25 exhibited broader antifungal spectrum.

As shown in Fig. 4 and Table 3 , A13 indicated effective protective activity at the concentration of 50 and 100 mg/L (51.613 and 70.968%), which was equal to boscalid (64.516 and 77.419%). Longitudinal section of the pear revealed that the decay caused by A. alternata not only expand on the surface of the pear but also spread into the interior of the pear.

The C1 substituents and the heterocyclic acid fragments of the amide bridge were identified as significant factors on modulating antifungal activity. When the heterocyclic acid fragment remains consistent, compounds featuring aromatic ring at the C1 position demonstrated higher antifungal efficacy compared to others ( A1-A4 versus A5-A32 ). Notably, among the aryl-substituents, para-substituted phenyl exhibited higher antifungal inhibition than the meta- and ortho-substituted phenyl, mono-substituted compounds ( A5-A28 ) displayed greater antifungal efficacy than multi-substituted compounds ( A29-A32 ). Compare between A13 - A16 with A25 - A28 , revealed that when the aryl-substituents are identical, the antifungal potency followed as thiophenyl > thiazolyl > pyrazolyl. Compounds containing thiophene heterocyclic fragments displayed pronounced antifungal activities and broad-spectrum for various pathogenic fungi. Molecular properties and drug-likeness evaluation The fungicidal activity and the in silico interaction with the assumed target enzyme were greatly affected by the chemical structure. The physical and chemical properties of highly active compounds A13 and A25 were calculated. As shown in the Table 4 , the chemical structure of A13 and A25 meet the Lipinski rule and demonstrate good drug-likeness.

SEM Analysis SEM analysis of A. alternata was conducted to investigate microstructural variations in the mycelia. The untreated mycelia exhibited a relatively uniform, robust, and smooth appearance (Fig. 5 A). In contrast, mycelia treated with compound A13 at concentrations of 50 mg/L and 100 mg/L significant coarsening were observed, with twisted and broken hyphae and a shriveled surface (Fig. 5 C, 5 D). These findings indicated that compound A13 induces substantial damage to the mycelia of A. alternata . Mechanism Molecular electrostatic potential was an important factor for activity and provide a meaningful reference for uncovering the interaction modes of the drug with the target. As shown in Fig. 6 , the positive region of compound A13 is relatively weak, and the negative region located around the oxygen atoms of the isoquinoline ring at C6, C7 methoxy, and the bridge carboxyl group. This distribution suggests the potential for the formation of hydrogen bonds with the target enyzem. Molecular docking simulations were performed to investigate the binding mechanism of compound A13 with succinate dehydrogenase (SDH, PDB: 2FBW). The CDOCKER Interaction Energy of A13 and boscalid were − 8.4 kcal/mol and − 8.3 kcal/mol, respectively. As illustrated in Fig. 7 (A, B), the isoquinoline ring of A13 engages in a Pi-sigma interaction with Leu A470, while the aromatic ring at the C1 position and the thiophenyl ring form Pi-cation interactions with the Arg A218. Additionally, the fluorine atom on the phenyl ring and the oxygen atom of the amide bond establish hydrogen bonds with the arginine residue (Arg B63). Notably, compared to boscalid, compound A13 exhibits a greater difference in binding sites and interaction modes with SDH. It provided a valuable reference for further modifcation of 1-arylisoquinoline derivatives. Conclusions In summary, a series of 32 novel 1-arylisoquinoline derivatives were designed, synthesized, and evaluated for their antifungal activities. The in vitro bioassay results showed that A13 and A25 exhibited effective antifungal activity against A. alternata as well as boscalid. The in vivo activities of A1 and A25 were investigated on pears and indicated that they can control A. alternate as well as boscalid at the dosage of 50 mg/L and 100 mg/L. The exploration of morphological observations indicated that compound A1 3 could strongly damage the mycelium morphology. Molecular electrostatic potential and molecular docking analysis revealed that A13 was covered by negative potential contour, and strongly interacts with the residues of SDH active pocket. This study showed a new way to optimize the tetrehydroisoquinoline alkaloids and further proved that 1-arylisoquinoline was a promising core for antifungal agents. Experimental Instruments and materials The melting points were determined by RY-1G melting point meter. 1 H NMR spectra and 13 C NMR spectra were recorded on Brucker Avance NEO 400 using CDCl 3 , DMSO- d 6 as solvent and tetramethylsilane as the internal standard, and chemical shift values ( δ ) were given in parts per million (ppm). High-resolution mass spectrometry (HRMS) data were obtained on Xevo G2-S Tof Mass Spectrometer (Waters). The crystal structure was recorded by a Rigaku XtaLAB P200 diffractometer. Column chromatography silica gel H type (Qingdao Ocean Chemical Plant, 200–300 mesh). Commercial reagents were analytically pure and used without further purification. All solvents were dried by standard methods in advance and distilled before use.

X-ray Diffraction Compound A5 was recrystallized by slow evaporation from a solution of tetrahydrofuran to afford a single crystal suitable for X-ray crystallography for structure validation. A crystal structure was performed on a Rigaku XtaLAB P200 diffractometer. The crystal was kept at 138.15 K during data collection. Using Olex2 [ 24 ], the structure was solved with the SHELXT [ 25 ] structure solution program using Intrinsic Phasing and refined with the SHELXL [ 26 ] refinement package using Least Squares minimisation. Optimization of thermal ellipsoid diagram of crystal by ORTEP-3 [ 27 ]. The crystallographic data of A5 can be download from the CCDC and the Supporting Information. Antifungal activity assay The in vitro activity of the target compounds A1-32 against Rhizotonia cerealis , Physalospora piricola , Fusarium graminearum , Colletotrichum lagenarium Botrytis Cinerea and Alternaria alternata were tested at 50 mg/L by mycelial growth rate method [ 28 – 29 ]. Chlorothalonil and boscalid were used as positive controls. The in vivo fungicidal activity against Alternaria alternata was evaluated at 50 mg/L and 100 mg/L on fragrant Pear. Boscalid as positive controls. Calculation of molecular properties and drug-likeness evaluation Molinspiration was used to calculate the main physical and chemical properties of the target compounds, such as the relative molecular weight, LogP (octanol/water partition coefficient), number of hydrogen bond donors and acceptors, and number of rotatable bonds [ 30 ]. ADMET lap was used to calculate the drug-likeness of the target compounds [ 31 ]. Molecular electrostatic potential analysis Compound A13 were selected for the molecular electrostatic potential analysis by density functional theory (DFT) method via Gaussian 09. The optimization of molecular conformation were carried out by the B3LYP method at 6-31G(d,p) level, and electrostatic potential calculation was based on the optimized structure [ 32 ]. Molecular docking Molecular docking simulation was performed by the CDOCKER module on AutoDock Vina1.1.2. The structures of the chose molecular was optimized and manually docked into the active site in porcine heart mitochondrial SDH from the RCSB Protein Data Bank (PDB ID: 2FBW). The crystal structure of SDH, compound A13 and positive control boscalid were treated according to standard procedures. The molecular docking results were analyzed and displayed by PyMol 2.5 [ 33 ]. SEM Analysis Mycelial morphology were made using scanning electron microscopy (SEM) technology according to previously reported methods [ 34 ]. The A. alternata mycelial cakes were cut from a PDA medium containing compound A13 (including 0.1% DMSO) at a 25 mg/L concentration. The mycelial cakes containing the same amount of DMSO were used as blank controls. Following the treatment according to the literature procedure, the mycelial morphology was observed under the scanning electron microscope.

Their structures were verified by 1H NMR, 13C NMR, HRMS and single X-ray crystal diffraction analysis. Most of the target products exhibited medium to excellent antifungal activity against 6 phytopathogenic fungi in vitro at a concentration of 50 mg/L. Interestingly, compounds A13 and A25 with EC50 values of 2.375, 2.251 mg/L s against A. alternate, that were similar to boscalid (EC50 = 1.195 mg/L). The in vivo experiments revealed that A13 presented 51.61% and 70.97% protection activities against A. alternate at the dosage of 50 and 100 mg/L, respectively, which were equal to that of boscalid (64.52% and 77.42%). The SEM analysis indicated that compound A13 could strongly damage the mycelium morphology. Molecular electrostatic potential and molecular docking analysis revealed that A13 was covered by negative potential contour, and strongly interacts with the residues of SDH. These results revealed that compounds A13 and A25 could be as promising antifungal candidates for the development of natural-based fungicides.","manuscriptTitle":"Design, synthesis, and mechanism study of novel 1-arylisoquinoline derivatives as antifungal agents","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2024-06-11 20:08:40","doi":"10.21203/rs.3.rs-4470733/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2024-09-05T04:05:02+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2024-09-04T12:22:09+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2024-08-26T16:05:18+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2024-08-24T14:23:09+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"161916192441168825782516601395661105769","date":"2024-08-24T12:42:38+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"169895726912045689406958350970057473172","date":"2024-08-24T10:03:48+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"64240181407595940724691188959988840988","date":"2024-08-22T05:11:24+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2024-08-13T02:38:29+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"35562427077939707840915179755867259342","date":"2024-08-13T01:39:36+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2024-06-04T00:38:16+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2024-05-25T19:30:45+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2024-05-25T08:32:59+00:00","index":"","fulltext":""},{"type":"submitted","content":"Molecular Diversity","date":"2024-05-24T07:30:24+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"molecular-diversity","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"modi","sideBox":"Learn more about [Molecular Diversity](http://link.springer.com/journal/11030)","snPcode":"11030","submissionUrl":"https://submission.nature.com/new-submission/11030/3","title":"Molecular Diversity","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"em","reportingPortfolio":"Springer Hybrid","inReviewEnabled":true,"inReviewRevisionsEnabled":false}}],"origin":"","ownerIdentity":"dfd6ff06-94ba-4dd6-9804-45279c9a4e6d","owner":[],"postedDate":"June 11th, 2024","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"published-in-journal","subjectAreas":[],"tags":[],"updatedAt":"2024-10-14T16:03:12+00:00","versionOfRecord":{"articleIdentity":"rs-4470733","link":"https://doi.org/10.1007/s11030-024-11012-6","journal":{"identity":"molecular-diversity","isVorOnly":false,"title":"Molecular Diversity"},"publishedOn":"2024-10-11 15:57:59","publishedOnDateReadable":"October 11th, 2024"},"versionCreatedAt":"2024-06-11 20:08:40","video":"","vorDoi":"10.1007/s11030-024-11012-6","vorDoiUrl":"https://doi.org/10.1007/s11030-024-11012-6","workflowStages":[]},"version":"v1","identity":"rs-4470733","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-4470733","identity":"rs-4470733","version":["v1"]},"buildId":"qtupq5eGEP_6zYnWcrvyt","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
