QSAR of 1, 4-Benzoxazin-2, 3- and 3, 1-Benzoxazin-2, 4-dione Antimicrobial Analogues
Recently, different benzoxazindione analogues were investigated for their antiviral, antiallergic and tocolytic oxytocin receptor activities. The benzoxazinone analogue efavirenz, i.e. 6-chloro-4-(cycloprophylethynyl)-1, 4-dihydro-4-(trifluoromethyl)-2H-3, 1-benzoxazin-2-one, was approved as antiretroviral drug, a non-nucleoside type of reverse transcriptase inhibitor. In extension of our previous QSAR studies using topological indices, TIs (W, X1, J), the QSAR of 1, 4-benzoxazin-2, 3-dione and 3, 1-benzoxazin-2, 4-dione analogues were explored using different computed molecular descriptors (MDs) and experimentally obtained parameters for antimicrobial activity (MIC). The biological activity were evaluated using G(+) and G(-) test bacteria and Candida monosa. In this study additional TIs and other MDs were explored (CID, X1, X MOD, VRA1, BID, Sv, Se and ALOGP) using multiple linear regression analysis. Previous results have shown significant correlation between antimicrobial activity (MIC) and topological indices (TIs), while in present, which are in good agreement with previously obtained, correlations indicate the preference of biological predictability on the basis of two or more TIs. This approach allows an investigation of influences more than one descriptor on particular system such as combination of constitutional (Sv, Se, ..), topological (ISIZ, MV1, … ), and molecular properties (ALOGP, MLOGP) descriptors. The good correlation was observed using constitutional (Sv) and topological (ZM1V) descriptors and antimicrobial activity (MIC) towards Klebsiella pneumoniae. 1. F. R. Calabri, et al., Eur. J. Med.
