The invention involves compounds of structural Formula (I) and the pharmaceutically acceptable salts thereof. The compounds of the invention are effective at selectively inhibiting CYP11B2, and are therefore useful for the treatment or prophylaxis of disorders that are associated with elevated aldosterone levels, including, but not limited to, hypertension and heart failure.

Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a recently validated therapeutic target for lowering low-density lipoprotein cholesterol (LDL-C). Through phenotypic screening, we previously discovered a class of small-molecules with a 2,3'-diindolymethane (DIM) skeleton that can decrease the expression of PCSK9. But these compounds have low potency and low metabolically stability. After performing structure-activity relationship (SAR) optimization by nitrogen scan, deuterium substitution and fluorine scan, we identified a series of much more potent and metabolically stable PCSK9 modulators. A preliminary in vivo pharmacokinetic study was performed for representative analogues difluorodiindolyketone (DFDIK) 12 and difluorobenzoimidazolylindolylketone (DFBIIK-1) 13. The in vitro metabolic stability correlate well with the in vivo data. The most potent compound 21 has the EC50 of 0.15 nM. Our SAR studies also indicated that the NH on the indole ring of 21 can tolerate more function groups, which may facilitate the mechanism of action studies and also allow further improvement of the pharmacological properties.

infected adult female Aedesaegypti mosquitoes and affect a large portion of the world's population. The Kir1channel in Ae. aegypti ( AeKir1) is an important ion channel in the functioning of mosquito Malpighian (renal) tubules and one that can be manipulated in order to disrupt excretory functions in mosquitoes. We have previously reported the discovery of various scaffolds that are active against
