Synthesis, Antimicrobial, and Molecular Docking Studies of 1,3-Thiazolidin-4-one Analogs Bearing Benzothiazole

The title compounds, 3-(7-substituted-6-fluoro-1,3-benzothiazole-2-yl)-2-(4-hydroxy-2-methoxy phenyl)-1,3-thiazolidine-4-ones (5a-k), were prepared by the reaction of 3-(7-chloro-6-fluoro-1,3-benzothiazole-2-yl)- 2-(4-hydroxy-2-methoxyphenyl)-1,3-thiazolidine-4-one (4) with substituted aromatic amines in dry dimethylformamide (DMF). The synthesized compounds were evaluated for their antimicrobial activity against bacterial (Gram positive, and Gram negative) and fungal strains. Compounds 5a-c, 5e, 5g, 5h, and 5k were found to be most active against various bacterial strains and compounds 5b and 5d against antifungal strains at very low concentration. In the docking study, the target protein (CYP450 3A4) was used against synthesized compounds. Among the titled compounds, 5b was found to be most potent and have a high docking score of -8.634 as compared to Ketoconazole (-6.55 as Dock Score).

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 108-59-8, you can contact me at any time and look forward to more communication. COA of Formula: C5H8O4.

Utility involving thioacetoacetanilides as precursors for synthesis of new thiazole, thiadiazole and thiophene derivatives with antimicrobial activity

The behavior of thioacetoacetanilide (1) and/or alpha-arylhydrazono-thioacetoacetanilides 4 toward many different alpha-halocarbonyl compounds was demonstrated. Thus, reactions of 1 with alpha-bromoketones (bromoacetone and phenacyl bromide) and hydrazonoyl bromides afforded the corresponding thiazole, thiophene and 1,3,4-thiadiazole derivatives, respectively. The synthesis and reactivity of thiazolidin-5-one 2 toward aromatic diazonium chlorides and aromatic aldehydes were described. Most of the synthesized compounds were screened for their antibacterial and antifungal activities and showed accepted antimicrobial activities with respect to the control drugs.

New thiourea and 1,3-thiazolidin-4-one derivatives effective on the HIV-1 virus

Thiourea derivatives have been reported to possess many biological activities, among them antiviral and antitumoral properties. As part of our continuing effort to develop new active compounds, we report the synthesis and the evaluation of new fifteen thiourea derivatives with 1,3-benzothiazole-2-yl moiety, among them a group of biologically active (1-7) also underwent cyclization to 1,3-thiazolidin-4-ones. Molecular structure of four compounds (4, 13, 15 and 3a) was determined by an X-ray crystallography. We here report the evaluation of their cytotoxicity against human leukaemia/lymphoma- and solid tumour-derived cell lines and of their antiviral activity against HIV-1 and representatives of ssRNA and dsDNA viruses. Derivative 5 showed an interesting activity against HIV-1 wild type and against variants carrying clinically relevant mutations. A colorimetric enzyme immunoassay clarified its mode of action as a non-nucleoside inhibitor of the reverse transcriptase.

New thiazoldinone substituted 2,6-diarypiperidin-4-one: Synthesis, crystal structure, spectral characterization, binding mode with calf thymus DNA

A series of 2,6-diarylpiperidin-4-ylidene thiazolidin-4-one derivatives (15-21) were efficiently synthesized using a green and recyclable catalyst Amberlit IR-120H resin under microwave irradiation. All the compounds were characterized by elemental analysis, FT-IR, H-1, C-13 NMR spectra. The conformation of the compound was unambiguously assigned by 2D NMR spectral analysis. Single crystal X-ray diffraction recorded for compound 21 and the data indicate that the compound crystallized in triclinic system with space group P (1) over bar. The observed chemical shifts and coupling constants suggested that the piperidone ring (15-21) adopts in chair conformation with equatorial orientations of the aryl groups. In solid state the configuration about C=N double bond is syn to C-5 carbon. All the compounds were screened for their in vitro antibacterial and antimycobacterial activities. Among the tested, compounds 17 and 18, were found to be potent inhibition with MIC values in the range of 0.2-0.8 mu g/mL. The interactions of the compounds with calf thymus DNA were investigated by spectroscopic method and the results indicated that compounds bound to Deoxyribo Nucleic Acid (DNA) by groove binding mode.

Utility of chloroacetonitrile in construction of some hitherto novel pyrazole and thiazole derivatives

2-(-Piperidin-1-yl) acetamide (2) was easily prepared by reacting chloroacetonitrile with piperidine. Furthermore, (2) was allowed to react with different aromatic aldehydes to afford novel arylidene derivatives (3a,b). Unexpectedly, 2-oxo-4-hydroxy-thiazole (5) was obtained instead of 2-(piperidin-1-yl-methylene) thiazolidin-4-one (4) when (2) was treated with mercaptoacetic acid under fusion conditions. Subsequent treatment of (5) with aromatic aldehydes and either malononitrile or cyanoacetamide (1:1:1 molar ratios) produced the hitherto unknown pyrano[2,3-d] thiazole derivatives (6a,b) and (7). Novel pyrazole derivatives (8a, b) and (9) were synthesized upon cyclocondensation of (2) with aromatic aldehydes and hydrazine hydrate. Unfortunately, attempts to prepare novel isoxazole derivatives by utilizing hydroxylamine instead of hydrazine hydrate following the previous procedure were failed. Surprisingly, the uncyclized products (10a,b) were obtained rather than 3-hydroxy-4-piperidinyl-isoxazole (11a,b). Upon refluxing thiosemicarbazide with (2) and aromatic aldehydes under the same conditions, pyrazolinone carbothioamides (12), (13) and (14a-c) were obtained.
