Discovery of novel and selective IKK-β serine-threonine protein kinase inhibitors. Part 1
摘要:
IkappaB kinase beta (IKK-beta) is a serine-threonine protein kinase critically involved in the activation of the transcription factor Nuclear Factor kappa B (NF-kappaB) in response to various inflammatory stimuli. We have identified a small molecule inhibitor of IKK-beta. Optimization of the lead compound resulted in improvements in both in vitro and in vivo potency, and provided IKK-beta inhibitors exhibiting potent activity in an acute cytokine release model (LPS-induced TNFalpha).

Synthesis and structure–activity relationships of 2-acylamino-4,6-diphenylpyridine derivatives as novel antagonists of GPR54
摘要:
GPR54 is a G protein-coupled receptor (GPCR) which was formerly an orphan receptor. Recent functional study of GPR54 revealed that the receptor has an essential role to modulate sex-hormones including GnRH. Though antagonists of GPR54 are expected to be novel drugs for sex-hormone dependent diseases such as prostate cancer or endometriosis, small molecule GPR54 antagonists have not been reported. We have synthesized a series of 2-acylamino-4,6-diphenylpyridines to identify potent GPR54 antagonists. Detailed structure-activity relationship studies led to compound 9l with an IC50 value of 3.7 nM in a GPR54 binding assay, and apparent antagonistic activity in a cellular functional assay.
