Neuropeptide S (NPS) is a potent agonist for the GPCR receptor NPSR1, implicated in various physiological and pathological processes, including inflammation. NPSR1 gene polymorphisms have been linked to asthma, inflammatory bowel disease, a…

EP2 is a G protein-coupled receptor for prostaglandin E2 (PGE2) derived from cell membrane-released arachidonic acid upon various harmful and injurious stimuli. It is commomly upregulated in tumors and injured brain tissues, as its activati…

Here we report on novel and potent pyridyl-cycloalkyl-carboxylic acid inhibitors of microsomal prostaglandin E synthase-1 (PTGES). PTGES produces, as part of the prostaglandin pathway, prostaglandin E2 which is a well-known driver for pain …

Aromatase inhibition is the new standard of care for estrogen receptor positive breast cancer and has also potential for treatment of other diseases such as endometriosis. Simple and readily available 3-pyridyl arylethers and 1-aryl pyrrolo…

The previously reported pyrrolidine class of progesterone receptor partial agonists demonstrated excellent potency but suffered from serious liabilities including hERG blockade and high volume of distribution in the rat. The basic pyrrolidi…

Antagonism of the gonadotropin releasing hormone (GnRH) receptor has resulted in positive clinical results in reproductive tissue disorders such as endometriosis and prostate cancer. Following the recent discovery of orally active GnRH anta…

The natural product withaferin A (WFA) is a potent angiogenesis inhibitor and it targets the ubiquitin-proteasome pathway in vascular endothelial cells. We generated a biotinylated affinity analog WFA-LC(2)B for use as a probe to study angi…

Small molecules designed to specifically activate or inactivate protein functions have been useful to study biological processes. PROTACS are small molecule chimera which comprise a ligand and a peptide recognition motif for an E3 ligase. T…
