Synthesis, SAR, In-Silico appraisal and Anti-Microbial Study of substituted 2-aminobenzothiazoles derivatives.

BACKGROUND
Antimicrobial resistance is major global health problem, which is being rapidly deteriorating the quality of human health. Series of substituted N-(benzo[d]thiazol-2-yl)-2-(4-(6-fluorobenzo[d]isoxazol-3-yl)piperidin-1-yl)acetamide (3a-j) were synthesized from substituted N-(benzo[d]thiazol-2-yl)-2-chloroacetamide/bromopropanamide (2a-j) and 6-fluoro-3-(piperidin-4-yl)benzo[d]isoxazole (2) and further evaluated for their docking properties and antimicrobial activity.


METHODS
All synthesized compounds were characterized by FT-IR, NMR and Mass spectral analysis. All compounds were allowed to dock against different antimicrobial targets having PDB ID: 1D7U and against common antifungal target having PDB ID: 1EA1.


RESULTS
The compounds 3d and 3h were showed good activity against Methicillin-resistant Staphylococcus aureus (MRSA, resistance Gram-positive bacteria). All synthesized compounds showed good to moderate activity against selected bacterial and fungal microbial strains. If we compared the actual in-vitro antimicrobial activity and in-silico molecular docking study, we found that molecules 3i and 3h were more potent than the others.


CONCLUSION
Our current study would definitely pave the new way towards designing and synthesis of more potent 2-aminobenzothiazoles derivatives.
