Abstract
New 6,7-dimethylquinoxalin-2(1H)-one and hydrazineylidene thiazol-4-one derivatives were synthesized, and evaluated for their in vitro antimicrobial activity. The obtained results revealed marked antimicrobial potential against four bacterial, and two fungal strains. Both 6,7-dimethyl-3-(2-(4-nitrophenyl)-2-oxoethyl)quinoxalin-2(1H)-one (4d), and 2-(2-(9H-fluoren-9-ylidene)hydrazineyl)-5-(2-(p-tolyl)hydrazineylidene)thiazol-4(5H)-one (11b) displayed significant antibacterial and antifungal activities having MIC ranges (1.98-15.6 mg/mL) and (1.98-3.9 mg/mL) compared to Tetracycline and Amphotericin B as standard drugs. In addition, they showed noticeable inhibitory activity against DNA gyrase enzyme. Interestingly the thiazole derivative (11b) showed marked inhibitory activity against DNA gyrase with IC50 = 7.82 ± 0.45 μM better than that of ciprofloxacin. The time-kill kinetics profile of the most active compounds against S. aureus and E. coli microorganisms displayed both concentration dependent and time dependent reduction in the number of viable cells. Furthermore, molecular docking study of both compounds in the DNA gyrase binding site was performed, showing agreement with the in vitro inhibitory activities.

Abstract
Background A novel series of thiazolidine-2,4-dione molecules was derived and their chemical structures were established using physiochemical parameters and spectral techniques (1H-NMR, IR, MS etc.). The synthesized molecule were then evaluated for their antioxidant, anticancer and antimicrobial potential. Results and discussion Serial tube dilution method was employed to evaluate the antimicrobial potential against selected fungal and bacterial strains by taking fluconazole and cefadroxil as reference antifungal and antibacterial drugs respectively. 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity was used to assess the antioxidant potential of the synthesized analogues. Further, the anticancer potential of the selected molecules was assessed against DU-145 cancer cell lines using MTT assay. The drug-likeness was also evaluated by studying in-silico ADME parameters of the synthesized analogues. Conclusion In antioxidant evaluation studies, the analogue H5 with IC50 = 14.85 μg/mL was found to be the most active molecule. The antimicrobial evaluation outcomes suggested that the molecules H5, H13, H15 and H18 possessed moderate to promising activity against the selected species of microbial strains having MIC range 7.3 µM to 26.3 µM. The results of anticancer evaluation revealed that all the screened derivatives possess mild anticancer potential. The in-silico ADME studies revealed that all the compounds were found to be drug-like.

Abstract
Compounds containing both thiazole and arylsulfone moieties are recognized for their high biological activity and ability to fight a variety of ailments. Thus, in this context, new derivatives of (thiazol-2-yl)hydrazone with an arylsulfone moiety were synthesized as CPTH2 analogs with potent anti-histone lysine acetyl-transferase activity. Compounds 3, 4, 10b, and 11b showed an excellent inhibitory effect on P300 (E1A-associated protein p300), compared to CPTH2. Among all the tested derivatives, compound 10b revealed the highest activity against both P300 and pCAF. In addition, the new hits were tested for anticancer efficacy against two leukemia cell lines. Most of them showed a moderate to potent antitumor effect on the k562 and CCRF-CEM cell lines. Interestingly, the activity of compound 10b against the k562 cell line was found to be higher than that of CPTH2. Furthermore, it showed a good safety profile, better than CPTH2 on normal cells. Molecular docking analysis was carried out to reveal the crucial binding contacts in the inhibition of the P300 and pCAF enzymes.

Novel anti-tubercular and antibacterial based benzosuberone-thiazole moieties: Synthesis, molecular docking analysis, DNA gyrase supercoiling and ATPase activity. Bioorg Chem 2020; 104:104316. [PMID: 33022549 DOI: 10.1016/j.bioorg.2020.104316] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2020] [Revised: 09/18/2020] [Accepted: 09/20/2020] [Indexed: 12/20/2022]
Abstract
Herein, molecular hybridization strategy was utilized in the design of new benzosuberone-thiazole derivatives. The structures of the synthesized hybrids were determined on the basis of elemental and spectral analyses. These compounds were evaluated for their antibacterial activities against five bronchitis causing bacteria in addition to their anti-tubercular activities. Most compounds revealed promising activities. Amongst active compounds, benzosuberone-dithiazole derivatives 22a and 28 with MIC value = 1.95 µg/ml against H. influenza, M. pneumonia, and B. pertussis displayed four times the activity of ciprofloxacin (MIC = 7.81 µg/ml) against H. influenza, twice the activity of ciprofloxacin (MIC = 3.9 µg/ml) against M. pneumonia and were equipotent to ciprofloxacin against B. pertussis (MIC = 1.95 µg/ml). Additionally, benzosuberone-dithiazole derivatives 22a and 27 were the most promising anti-tubercular among the tested compounds with MIC values of 0.12 and 0.24 µg/ml, respectively against sensitive M. tuberculosis in addition to high activity against resistant strain of M. tuberculosis (MIC = 0.98 and 1.95 µg/ml, respectively) compared to isoniazid (MIC = 0.12 µg/ml against sensitive M. tuberculosis and no activity against resistant M. tuberculosis). Cytotoxicity study of the active dithiazole derivatives 22a, 27 and 28 against normal human lung cells (WI-38) indicated their high safety profile as showed from their high IC50 values (IC50 = 107, 74.8, and 117 µM, respectively). Furthermore, DNA gyrase supercoiling and ATPase activity assays showed that 22a, 27 and 28 have the potential to inhibit DNA gyrase at low micromolar levels (IC50 = 3.29-15.64 µM). Molecular docking analysis was also carried out to understand the binding profiles of the synthesized compounds into the ATPase binding sites of bacterial and mycobacterial DNA gyraseB.
