This paper studies deep learning methods for predicting drug-target interactions by improving representation learning through multimodal drug information and bidirectional cross-attention. Using two drug modalities—molecular images and chemical text—plus a decoder architecture that combines multi-head self-attention and a bidirectional multi-head cross-attention block to generate interaction feature maps, the model fuses these representations to output DTI predictions. The authors report that MCL-DTI achieves best results across three datasets (Human, C. elegans, and Davis) for both balanced and an unbalanced dataset, and they additionally evaluate generalization on a drug-drug interaction task. The preprint provides no explicit caveats or limitations in the provided text. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Background: Prediction of drug-target interaction (DTI) is an essential step fordrug discovery and drug reposition. Traditional methods are mostlytime-consuming and labor-intensive, and deep learning-based methods addressthese limitations and are applied to engineering. Most of the current deeplearning methods employ representation learning of unimodal information such as SMILES sequences, molecular graphs, or molecular images of drugs. In addition,most methods focus on feature extraction from drug and target alone withoutfusion learning from drug-target interacting parties, which may lead toinsufficient feature representation. Results: : To enhance feature learning between drugs and targets, we propose anovel model based on deep learning for DTI task called MCL-DTI which usesmultimodal information of drug and learn the representation of drug-targetinteraction for drug-target prediction. In order to further explore a morecomprehensive representation of drug features, this paper first exploits twomultimodal information of drugs, molecular image and chemical text, to representthe drug. We also introduce to use bi-rectional multi-head corss attention (MCA)method to learn the interrelationships between drugs and targets. Thus, we buildtwo decoders, which include an multi-head self attention (MSA) block and anMCA block, for cross-information learning. We use a decoder for the drug andtarget separately to obtain the interaction feature maps. Finally, we feed thesefeature maps generated by decoders into a fusion block for feature extraction andoutput the prediction results. Conclusions: : MCL-DTI achieves the best results in all the three datasets:Human, C.elegans and Davis, including the balanced datasets and an unbalanceddataset. The results on the drug-drug interaction (DDI) task show that MCL-DTIhas a strong generalization capability and can be easily applied to other tasks.
