The development of new antimicrobial agents capable of curing drug-resistant bacteria-induced infections is becoming a major challenge to the global healthcare system. To develop antimicrobials with new molecular entities, a series of novel carbazole-based compounds were designed and synthesized by biomimicking the structural properties and biological function of antimicrobial peptides. Compound 29 was selected as a lead compound from the structure-activity relationship analyses and biological activity evaluation. Compound 29 showed excellent antimicrobial activity against Gram-positive bacteria (MICs = 0.78-1.56 μg/mL), poor hemolytic activity (HC50 > 200 μg/mL), and low cytotoxicity to mammalian cells. Compound 29 had fast bactericidal properties and effectively prevented bacterial resistance in laboratory simulations. Antibacterial mechanism studies revealed that compound 29 directly destroyed bacterial cell membranes, leading to bacterial deaths. Importantly, compound 29 displayed an excellent efficacy in a murine bacterial keratitis model caused by Staphylococcus aureus ATCC29213.

experimental part, p. 606 - 610 (2010/12/25)
A facile synthesis of Carvedilol via a key 5-substituted-.-oxazolidinone intermediate is described and this approach avoids the formation of bis side product (impurity B). This approach could be useful for the preparation of many β-amino alcohols without formation of bis impurity.
