- Abstract
BM635 is a small molecule endowed with outstanding anti-mycobacterial activity (minimum inhibitory concentration of 0.12μM against M. tuberculosis H37Rv) identified during a hit-to-lead campaign. Its poor aqueous solubility together with its high lipophilicity led to low exposure in vivo. Indeed, the half-life in vivo of BM635 was 1h, allowing a reasonable maximum concentration (C
max =1.62μM) and a moderate bioavailability (46%). The present study aimed to develop salt forms of BM635 with pharmaceutically accepted hydrochloric, methanesulphonic, phosphoric, tartaric, and citric acids to overcome these drawbacks. BM635 salts (BM635-HCl, BM635-Mes, BM635-PA, BM635-TA and BM635-CA) were evaluated for physicochemical as well as biopharmaceutical attributes., (Copyright © 2016 Elsevier B.V.
