Antibacterial evaluation and molecular docking studies of pyrazole-thiosemicarbazones and their pyrazole-thiazolidinone conjugates

A library of pyrazole-thiazolidinone conjugates was synthesized using a molecular hybridization approach through a Vilsmeier-Haack reaction. The compounds were tested for anti-microbial activity against two Gram-positive bacteria (Staphylococcus aureus and methicillin-resistant Staphylococcus aureus) and four Gram-negative bacteria (Escherichia coli, Salmonella typhimurium, Klebsiella pneumonia and Pseudomonas aeruginosa). Among the compounds tested, 3-((2,4-dichlorophenyl)-1-(2,4-dinitrophenyl)-1H-pyrazol-yl)methylene)hydrazinecarbothioamide (3a) and 2-((3-(2-chlorophenyl)-1-(2,4 dinitrophenyl)-1H-pyrazol-4-yl)methyleneamino)thiazolidin-4-one (4b) emerged as the most potent anti-microbial compounds with minimum bactericidal concentrations of < 0.2 mu M against MRSA and S. aureus. Structure-activity relationship analysis further revealed that the presence of 2,4-dichloro moiety surprisingly influenced the activity of the compounds. Molecular docking studies of the compounds into the crystal structure of topoisomerase II and topoisomerase IV suggest that compounds 3a and 4b preferably interact with the targets through hydrogen bonding. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 6118-51-0, in my other articles.

Synthesis and evaluation of antibacterial and antifungal activities of 4-thiazolidinones and 2-azetidinones derivatives from chalcone

(E)-3-(thiophen-2-yl)-1-(4-methylphenyl)-prop-2-en-1-one 1 was obtained from the reaction of thiophene-2-aldehyde with p-methyl acetophenone. The treatment of 1 with guanidine nitrate produced 4-thiophen-2-yl-6-(4-methylphenyl)-pyrimidin-2-ylamine 2. The synthesis of N-substituted benzylidine-4-(4-methylphenyl)-6-(thiophen-2-yl) pyrimidin-2-amines 3a-j was performed by the treatment of compound 2 with the corresponding aromatic aldehydes. The reaction of 3a-j with thioglycolic acid and thiolactic acid formed the corresponding 3-[4-(4-methyl-phenyl)-6-thiophen-2-yl-pyrimidin-2-yl]-2-(substituted-phenyl)-thiazolidin-4-ones 4a-j and 3-[4-(4-methyl-phenyl)-6-thiophen-2-yl-pyrimidin-2-yl]-2-(substituted-phenyl)-5-methyl-thiazolidin-4-ones 5a-j and with chloroacetylchloride, it gives 3-chloro-1-[4-(4-methyl-phenyl)-6-thiophen-2-yl-pyrimidin-2-yl]-4-(substituted-phenyl)-azetidin-2-ones 6a-j. Newer analogues were characterized by infrared spectrum, H-1 nuclear magnetic resonance, C-13 nuclear magnetic resonance spectroscopy and elemental analyses. The newly synthesized analogues were then examined for their antimicrobial activity against some bacterial and fungal strains as two Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa), two Gram-positive bacteria (Staphylococcus aureus, Streptococcus pyogenes) and two fungal species (Candida albicans, Aspergillus niger, Aspergillus Clavatus) to develop a novel class of antimicrobial agents.

ASSESSMENT OF IN VITRO ANTIOXIDANT ACTIVITY OF SOME NEW FERULIC ACID DERIVATIVES

Aim: The in vitro antioxidant potential of new thiazolidin-4-one derivatives of ferulic acid was evaluated according to the total antioxidant activity and ferric reducing power assays. Material and methods: The ferric reducing power assay was based on the reduction of ferricyanide to ferrocyanide, which form in the presence of ferric chloride a Perl Prussian blue color complex. The total antioxidant activity assay was assessed using phosphomolybdenum method. The results were expressed as effective concentration (EC50) values and ascorbic acid was used as positive control. All determinations were performed in triplicate. Results: It was found that the activity of the tested compounds is influenced by the substituents on phenyl ring of the thiazolidine-4-one moiety. The most active compound was 1i, which contains 2,3-diOH as substituent on phenyl ring. Conclusions: A total of 10 new thiazolidin-4-one derivatives of ferulic acid were investigated for their in vitro antioxidant activity. The most active compound 1i (R=2,3-diOH) proved to be about 4 times more active than ferulic acid and comparable to ascorbic acid in both antioxidant assays.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 10097-02-6. COA of Formula: C6H12O4.

Novel Thiazolidinone-Azole Hybrids: Design, Synthesis and Antimycobacterial Activity Studies

To develop novel antimycobacterial agents, a new series of thiazolidinone-azole hybrids 4a-b, 5a-b and 6-13 were designed and synthesized. Thiazolidin-4-ones (4a-b and 5a-b) were obtained by the reaction of Schiff bases and hydrazones (2a-b and 3a-b) with mercaptoacetic acid. 5-Benzylidene derivatives (6-13) were gained by treatment of 5a-b with appropriate benzaldehydes according to Knoevenagel condensation. To evaluate their structures H-1 NMR, IR, mass spectrometry and elemental analysis data were used. The target compounds were screened for their antimycobacterial activity against M. tuberculosis H37Rv strain using the microplate alamar blue assay method. Among them, 6, 10 and 12 (MIC: 14.27-14.74 mu M) were found as most active compounds in the series. It was seen that both phenylamino and benzylidene substitutions on thiazolidin-4-one ring caused an improvement in the antimycobacterial activity.

Synthesis of novel indole derivatives as promising DNA-binding agents and evaluation of antitumor and antitopoisomerase I activities

Molecules bearing indole nucleus present diverse biological properties such as antitumor and antiinflammatory activities that can be associated both to DNA and protein interactions. This study focused on the synthesis of new indole derivatives with thiazolidines and imidazolidine rings condensed as side chains as well as the evaluation of their ability to interact with the DNA and antitumor and topoisomerase inhibition activities. All derivatives were successfully synthesized and their structures were elucidated by mass spectrometry (MS), infrared (IR), spectroscopy H-1 NMR,C-13 NMR, COSY H-1-H-1 and HSQC H-1-C-13. The antitumor activity was evaluated against different cancer cell lines using the antiproliferative MTT assay. DNA binding ability was analyzed by absorption spectroscopy and fluorescence technique using ethidium bromide (EB) as a fluorescent probe. Changes were observed in spectroscopic properties of the compounds after interacting with ctDNA (calf thymus DNA), with hypochromic and hyperchromic effects, besides blue or red shifts in the maxima of spectra. The indole derivative 5-(1H-Indo1-3-ylmethylene)-thiazolidin-2,4-dione (4c) presented the best results in antitumor assay against the breast line tested (T47D), with IC50 value lower than the positive control, doxorubicin (1.93 and 4.61 mu M, respectively). On the other hand, the compound 3-amino-5-(1H-indo1-3ylmethylene)-2-thioxo-thiazolidin-4-one (4a) was active against leukemia cell lines (HL60 and K562) with the high value of the DNA binding constant, Kb of 5.69 x 10(4). However, this compound (4a) did not inhibit the topoisomerase-I activity evaluated by relaxation assay. These results show that the indole nucleus contribute to the incorporation of molecules into the DNA. Moreover, it was highlighted that basic side chains, such as thiazolidines and imidazolidines, and free amino group, are relevant for design of promising antitumor and DNA binding compounds.
