Abstract

The QSAR analysis of a set of previously synthesized 5-substitutedbenzamido- and 5-substitutedphenylacetamido -2- (p-substituted-phenyl) benzoxazole derivatives, which were tested in vitro for their growth inhibitory activity against Bacillus subtilis, was performed by using the stepwise multiple regression analysis. The resulting QSAR revealed that the substitution at position R2 is more significant than R and R1 to improve the antibacterial activity. Hydrophobic and steric effects of substituents at R2 have an important role for increasing the antibacterial activity compared to other parameters.

Özet

Bu kantitatif yapı-etki ilişkileri analizinde önceden sentezleri gerçekleştirilmiş ve B. subtilis'e karşı in vitro gelişimlerini inhibe etme aktiviteleri test edilmiş olan 5-sübstitüebenzamido- ve 5-sübstitüefenilasetamido -2- (p-sübstitüefenil) benzoksazol türevlerine basamaklı çoklu regresyon analizi uygulandı. Kantitatif yapı-etki ilişkileri analiz sonuçları, R2 konumunun R ve R1'den antibakteriyal aktivite için daha önemli olduğunu ortaya koymuştur. R2'nin hidrofobik ve sterik etkileri antibakteriyal aktivitenin artması için diğer parametrelerden daha önemlidir.
