GPR119 is a 7-transmembrane receptor that is expressed in the enteroendocrine cells in the intestine and in the islets of Langerhans in the pancreas. Indolines and 6,7-dihydro-5H-pyrrolo[2,3-a]pyrimidines were discovered as G protein-coupled receptor 119

A series of N-pyridyl benzamide KCNQ2/Q3 potassium channel openers were identified and found to be active in animal models of epilepsy and pain. The best compound 12 [ICA-027243, N-(6-chloro-pyridin-3-yl)-3,4-difluoro-benzamide] has an EC50 of 0.38 μM and is selective for KCNQ2/Q3 channels. This compound was active in several rodent models of epilepsy and pain but upon repeated dosing had a number of unacceptable toxicities that prevented further development. On the basis of the structure-activity relationships developed around 12, a second compound, 51, [N-(2-chloro-pyrimidin-5-yl)-3,4-difluoro- benzamide, ICA-069673], was prepared and advanced into a phase 1 clinical study. Herein, we describe the structure-activity relationships that led to the identification of compound 12 and to the corresponding pyrimidine 51.

Contrary to the common idea that Fischer indole cyclization often cannot be effectively applied to the synthesis of the corresponding azaindoles, we show that this approach can be actually very efficient for the formation of 4- and 6-azaindoles bearing an electron-donating group on the starting pyridylhydrazines. Two 4-azaindole natural product analogues were synthesized in a few steps and very good overall yields.

This report describes the synthesis and pharmacological evaluation of a series of novel potassium channel openers related to the pinacidil-type compounds. Thioureas, cyanoguanidines, and pyridine N-oxides were systematically evaluated for their effects on both the inhibition of spontaneous mechanical activity in rat portal vein (in vitro) and their antihypertensive activity (in vivo), and the structure-activity relationship for this series of compounds was discussed. Good correlation between in vitro and iv antihypertensive activity was observed for these compounds. Among them, cyanoguanidines bearing a conformationally rigid unit such as a norbornyl group generally possessed potent activity in both in vitro and in vivo studies. Especially, N-(6-amino-3-pyridyl)-N'-cyano-N''-(1-methyl-2- norbornyl)guanidine (23d) was identified as a more potent potassium channel opener in vitro (EC100 = 3 x 10-8 M) than pinacidil (EC100 = 10-7 M).
