Therapeutic Activities

Heterocyclic compounds with thiazole moiety are one of the most promising compounds in the medicinal chemistry possessing numerous therapeutic activities. The present was designed to study the high throughput in silico screening of 10 designed 2-phenyl-amino thiazole derivatives as a potent FABH inhibitor in Molegro virtual docker software (Version 6.0) using 3iL9 as PDB. The docking results showed mol dock score of -90.94 with four hydrogen bonding for the standard drugs griseofulvin, while on the other hand, N-substituted thiazole derivatives S2, S5, S6, S7, S8, and S9 exhibited excellent mol dock score, ranged from -102.612 to -144.236, hydrogen bonding (4-10), and docking score ranged from -104.873 to -143.593. Similarly, another in silico study was done using online PASS software and the compounds S1, S2, S5, S6, S7, S8, and S9 have Pa ranged between 0.310 to 0.411 and showed good antibacterial activity whereas, compounds having Pa ranged between 0.216 to 0.334 demonstrated potent antifungal activity when compared to standard drugs. Thus, the present study affirmed the significant antimicrobial potential of some designed N-substituted thiazole derivatives based on their mol dock values and other parameters when studies in silico and the obtained results will provide data support and offer perspectives in future researches to develop potent antimicrobial agents from these N-substituted thiazole 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.

A series of 1-(5-(5-(4-chlorophenyl)furan-2-yl)-4,5-dihyropyrazol-1-yl ethanone (5a-h) was synthesized through E-(3-(5-(4-chloro-phenyl)furan-2-yl)-1-phenylprop-2-en-1-one (3a-h) with hydrazine monohydrate and sodium acetate. Totally, eight compounds were synthesized and their structures were elucidated by infrared, 1H & 13C NMR, elemental analysis, antimicrobial studies, in silico molecular docking studies and also in silico ADME prediction. Antimicrobial studies of the synthesized compounds showed good to moderate activity against the all the stains compared with standard drugs. in silico Molecular docking study was carried out using bacterial protein and BC protein. Synthesized compounds (5a-h) showed good docking score compared with ciprofloxacin. Antimicrobial study was carried out for 4-chlorophenyl furfuran pyrazole derivatives (5a-h). The results of assessment of toxicities, drug likeness and drug score profiles of compounds (5a-j) are promising

In Silico Study

The rise in the incidence of cervical cancer globally has accentuate attention to the potential role of polyphenols as anticancer agents. Different studies have demonstrated the role of some polyphenols in altering Human Papillomavirus (HPV) carcinogenesis. Thus, this study was aimed at establishing the potentials of Schiff-based polyphenols from imesatin and satin as anticancer agents through in silico analysis. The polyphenols were synthesized and characterized using elemental analyses, spectroscopic analyses, UV-visible, Infrared, and Nuclear Magnetic Resonance (1H NMR and 13C, NMR). Molecular docking study of the polyphenols was carried out using Auto Dock Vina. The oncogenic E6 protein structure of HPV 16 was obtained from the protein bank (ID: 4XR8). The E6 proteins were prepared using AutoDock tools. Water molecules were removed from the protein molecules while hydrogen atoms were added. Also, the structures of Curcumin and Isomericitrin were obtained from PubChem. Results showed that three different Schiff based polyphenols were obtained from the synthesis; 3-(2’,4’-dimethoxy benzylidene hydrazono) indoline-2-one (DMBH), 3-(2’-hydroxy-4’-methoxy benzylidene hydrazono) indoline-2-one (HMBD), and 3-((4-4’-((2’’, 4’’-dimethoxy benzylidene amino) benzyl)phenyl)imino) indoline-2-one (DMBP). Higher ability of the docked polyphenols to bind to the E6/E6AP/p53 complex when compared to Curcumin was revealed. Also, results showed that the binding energy of Curcumin and Isomericitrin were -7.1kcal/mol and -8.4kcal/mol respectively while that of the polyphenols ranged from -7.4kcal/mol to -7.9kcal/mol. The molecular docking results of the polyphenols used in this study further confirm their potentials as strong anti-cancer agents.
