Abstract
MRSA infection is one of the alarming diseases in the current scenario. Identifying newer molecules to treat MRSA infection is of urgent need. In the present study, we have designed fluorinated thiazolidinone derivatives with various aryl/heteroaryl units at 5 th position of the thiazolidinone core as promising anti-MRSA agents. All the compounds were screened for antibacterial activity against four bacterial strains. Among the tested compounds, the halogenated compounds with simple arylidene ring, 5-(3-chloro-2-fluorobenzylidene)-2-(thiazol-2-ylamino)thiazol-4(5H)-one ( 4b) , 5-(4-chloro-2-fluorobenzylidene)-2-(thiazol-2-ylamino)thiazol-4(5H)-one ( 4c ), 5-(3-fluoro-4-methylbenzylidene)-2-(thiazol-2-ylamino)thiazol-4(5H)-one ( 4f ) and 5-(3,5-difluorobenzylidene)-2-(thiazo-2-ylamino)thiazol-4(5H)-one ( 4g) showed excellent activity with MIC 3.125-6.25 µg/mL against S. aureus and P. aeruginosa organism. Furthermore, these potent compounds were screened against MRSA strains, ESKAPE panel organism, and H37Rv mycobacterium strain. Compounds 4c (MIC 0.39 µg/mL), and 4f (MIC 0.39 and 0.79 µg/mL) displayed promising activity against MRSA strains (ATCC and clinical isolates, respectively). The most potent compounds, 4c and 4f eradicated the growth of bacterial colonies in a time-kill assay indicated that these are bactericidal in nature. The preliminary toxicity study of the potent molecules revealed that these compounds are non-hemolytic in nature as they did not induce lysis in human RBCs. In addition, the molecular docking and dynamics studies of compounds 4b , 4c , 4f and 4g were carried out on MurB protein of S. aureus (PDB code: 1HSK). Docking results demonstrated remarkable hydrogen bonding interaction with key amino acids ARG310, ASN83, GLY79 and π-π interactions with TYR149 which confirm the mode of action of the molecules.

One-Pot Multicomponent Synthesis and Bioevaluation of Tetrahydroquinoline Derivatives as Potential Antioxidants, α-Amylase Enzyme Inhibitors, Anti-Cancerous and Anti-Inflammatory Agents. Molecules 2020; 25:E2710. [PMID: 32545290 PMCID: PMC7321408 DOI: 10.3390/molecules25112710] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Revised: 06/05/2020] [Accepted: 06/07/2020] [Indexed: 11/16/2022] Open
Abstract
Mankind has always suffered from multiple diseases. Therefore, there has been a rigorous need in the field of medicinal chemistry for the design and discovery of new and potent molecular entities. In this work, thirteen tetrahydroquinoline derivatives were synthesized and evaluated biologically for their antioxidant, α-amylase enzyme inhibitory, anti-proliferative and anti-inflammatory activities. SF8 showed the lowest IC50 of 29.19 ± 0.25 µg/mL by scavenging DPPH free radicals. SF5 showed significant antioxidant activity in total antioxidant capacity (TAC) and total reducing power (TRP) assays. SF5 and SF9 showed the maximum inhibition of α-amylase enzyme i.e., 97.47% and 89.93%, respectively, at 200 µg/mL concentration. Five compounds were shortlisted to determine their anti-proliferative potential against Hep-2C cells. The study was conducted for 24, 48 and 72 h. SF8 showed significant results, having an IC50 value of 11.9 ± 1.04 µM at 72 h when compared with standard cisplatin (IC50 value of 14.6 ± 1.01 µM). An in vitro nitric oxide (NO) assay was performed to select compounds for in vivo anti-inflammatory activity evaluation. SF13 scavenged the NO level to a maximum of 85% at 50 µM concentration, followed by SF1 and SF2. Based on the NO scavenging assay results, in vivo anti-inflammatory studies were also performed and the results showed significant activity compared to the standard, acetylsalicylic acid (ASA).

Abstract
A series of newer 1,2,4-triazole-3-thiol derivatives 5(a-m) and 6(a-i) containing a triazole fused with pyrazine moiety of pharmacological significance have been synthesized. All the synthesized compounds were screened for their in vitro antileishmanial and antioxidant activities. Compounds 5f (IC50=79.0µM) and 6f (IC50=79.0µM) were shown significant antileishmanial activity when compared with standard sodium stibogluconate (IC50=490.0µM). Compounds 5b (IC50=13.96µM) and 6b (IC50=13.96µM) showed significant antioxidant activity. After performing molecular docking study and analyzing overall binding modes it was found that the synthesized compounds had potential to inhibit L. donovani pteridine reductase 1 enzyme. In silico ADME and metabolic site prediction studies were also held out to set an effective lead candidate for the future antileishmanial and antibacterial drug discovery initiatives.

Abstract
Seven new 4-thiazolidinones bearing the morpholino moiety were easily synthesized by one-pot reactions of 4-(2-aminoethyl)morpholine (2-morpholinoethylamine), arenealdehydes and mercaptoacetic acid refluxing toluene for 19 h with moderate to good yields (45-97%). These novel compounds were fully identified and characterized by NMR spectroscopy and mass spectrometry. Thiazolidin-4-ones in vivo anti-inflammatory activities were determined using a croton oil-induced ear edema model of inflammation in BALB C mice. The best results were found for compounds 4c (49.20 mmol/kg), 4d (49.20 mmol/kg) and 4f (52.48 mmol/kg), which showed the ability to decrease the ear edema in mice by 50%, 48% and 54%, respectively, when compared to the standard drug indomethacin. In addition, the in vitro cytotoxicity activity of thiazolidin-4-ones against Vero cells was also performed and four compounds (4a, 4c, 4d and 4f) showed no toxic effect at 500 μg/mL. A docking simulation of compounds into the 1Q4G (COX-1) and 4PH9 (COX-2) enzymes binding site was conducted. This preliminary result will guide us in for further studies to improve the anti-inflammatory activity.
