Several five-membered heterocycles having a phenylazo substituent, 3-phenylazotetronic acids (2a-n), 3-phenylazotetramic acids (4a-i), 4-phenylazo-5-isoxazolinones (6a-g, 8a-f) and 5-phenylazo-4-thiazolidinones (10a-f, 12a-e), were synthesized and tested for antimicrobial activities. Tetronic acid and tetramic acid derivatives (2 and 4) inhibited the growth of gram-positive bacteria. 5-Isoxazolinone and 4-thiazolidinone derivatives (8 and 10) showed inhibitory activities against fungi as well as bacteria.

A renaloutermedullarypotassiumchannel (ROMK, Kir1.1) is a putative drug target for a novel class of diuretics with potential for treating hypertension and heart failure. Our first disclosed clinical ROMK compound, 2 (MK-7145), demonstrated robust diuresis, natriuresis, and blood pressure lowering in preclinical models, with reduced urinary potassium excretion compared to the standard of care diuretics
