Synthesis and on-target antibacterial activity of novel 3-elongated arylalkoxybenzamide derivatives as inhibitors of the bacterial cell division protein FtsZ
摘要:
Novel 3-elongated arylalkoxybenzamide derivatives were designed, synthesized and evaluated for their cell division inhibitory activity and antibacterial activity. Among them, the subseries of 3-alkyloxybenzamide derivatives exhibited greatly improved on-target activity against Bacillus subtilis and Staphylococcus aureus, and remarkably increased antibacterial activity against B. subtilis ATCC9372, penicillin-susceptible S. aureus ATCC25923, methicillin-resistant S. aureus ATCC29213 (MRSA) and penicillin-resistant S. aureus PR compared with 3-methoxybenzamide. In contrast, the subseries of 3-phenoxyaklyloxybenzamide, 3-heteroarylalkyloxybenzamide and 3-heteroarylthioalkyloxybenzamide derivatives only showed a significant improvement in on-target activity and antibacterial activity against B. subtilis ATCC9372.

A range of 3-oxybenzamide compounds and related quinazolinone compounds are disclosed which can act as potent inhibitors of the DNA repair enzyme poly(ADP-ribose) polymerase or PARP enzyme (EC 2.4.2.30), and which thereby can provide useful therapeutic compounds for use in conjunction with DNA-damaging cytotoxic drugs or radiotherapy to potentiate the effects of the latter. The compounds disclosed include 3-benzyloxybenzamides, 3-oxybenzamides in which a chain of 5 or more methylene groups terminate in a halogen atom or in a purin-9-yl moiety, certain benzoxazole-4-carboxamide compounds and certain quinazolinone compounds. In formula X and Y together may form a bride --X--Y-- that represents the grouping (a), (b) or (c )wherein R.sup.5 is H, alkyl, aryl or aralkyl.

Benzoxazole carboxamides are disclosed which can act as potent inhibitors of the DNA repair enzyme poly(ADP-ribose) polymerase or PARP enzyme (EC 2.4.2.30), and which thereby can provide useful therapeutic compounds for use in conjunction with DNA-damaging cytotoxic drugs or radiotherapy to potentiate the effects of the latter. Representative of the compounds are 2-methyl, 2-t-butyl, 2-phenyl or 2-(4-methoxyphenyl) benzoxazole-4-carboxamide.
