Abstract
The present study describes the antibacterial activity of several new derivatives of tacrine or cyclopentaquinoline bound to either 6-hydrazinenicotinic acid or 4-fluorobenzoic acid through an aliphatic chain against methicillin-resistant staphylococcal strains. All derivatives showed antibacterial activity against all tested methicillin-resistant staphylococci. Of these, compounds 6, 18, 23 and 24 exhibited the highest activity, ranging from 4.87 to 19.5 μg/mL MBC (Minimum Bactericidal Concentration) depending on the bacterial strain. These values were not much greater than that for vancomycin, the reference standard for the treatment of methicillin-resistant Staphylococci infections in humans. In addition, all synthesized compounds underwent a quantitative structure-activity relationship analysis. Correlation and multicollinearity tests were used to select descriptors as independent variables for multiple linear regression models to quantify the relationships between biological activity and the structural parameters.
