Silica chloride (SiO2-Cl) catalyzed one pot synthesis of 2,3-disubstituted-thiazolidin-4-one

In this paper, we report one-pot, three-component cyclo condensation of an aldehyde, an amine and thioglycolic acid to form 2,3-disubstituted-thiazolidin-4-one by using supported protic acid (Silica Chloride: SiO2-Cl) catalyst. The catalyst SiO2-Cl is compatible with a variety of aldehydes (aryl/heteroaryl) and the aromatic amines affording 2,3-disubstituted-thiazolidin-4-one analogs in 72-89% yields. Moreover, the supported catalyst was recycled several times without significant loss of catalytical activity

Steric Enforcement about One Thiolate Donor Leads to New Oxidation Chemistry in a NiSOD Model Complex

Ni-containing superoxide dismutase (NiSOD) represents an unusual, member of the SOD family due to the presence of oxygen-sensitive Ni Says bonds at its active site. Reported in this account is the synthesis and properties of the Ni-II complex of the N3S2 ligand [N3S2Me2](3-) ([N3S2Me2](3-) = deprotonated form of 2-((2-mercapto-2-methylpropyl)(pyridin-2-ylmethyl)amino)-N-(2-mercaptoethyl)acetamide), namely Na[Ni(N3S2Me2)] (2), as a NiSOD model that features sterically robust gem-(CH3)(2) groups on the thiolate alpha-C positioned trans to the carboxamide. The crystal structure of 2, coupled with spectroscopic measurements from H-1 NMR, X-ray absorption, IR, UV-vis, and mass spectrometry (MS), reveal a planar Ni-II (S = 0) ion coordinated by only the N2S2 basal donors of the N3S2 ligand. While the structure and spectroscopic properties of 2 resemble those of NiSODred and other models, the asymmetric S ligands open up new reaction paths upon chemical oxidation. One unusual oxidation product is the planar Ni-II-N3S complex [Ni(L-ox)] (5; L-ox = 2-(5,5-dimethyl-2-(pyridin-2-yl)thiazolidin-3-yl)-N-(2-mercaptoethyl)acetamide), where two-electron oxidation takes place at the substituted thiolate and py-CH2 carbon to generate a thiazolidine heterocycle. Electrochemical measurements of 2 reveal irreversible events wholly consistent with thiolate redox, which were identified by comparison to the ZIP complex Na[Zn(N3S2Me2)] (3). Although no reaction is observed between 2 and azide, reaction of 2 with superoxide produces multiple products on the basis of UV-vis and MS data, one of which is S. Density functional theory (DFT) computations suggest that the HOMO in 2 is pi* with primary contributions from Ni-d pi/S-p pi orbitals. These contributions can be modulated and biased toward Ni when electron-withdrawing groups are placed on the thiolate alpha-C. Analysis of the oxidized five-coordinate species 2(ox)* by DFT reveal a singly occupied spin-up (alpha) MO that is largely thiolate based, which supports the proposed Ni-III-thiolate/Ni-II-thiyl radical intermediates that ultimately yield 5 and other products.

Synthesis, Biological Evaluation and Molecular Modeling Studies of New 2,3-Diheteroaryl Thiazolidin-4-Ones as NNRTIs

In a focused exploration, thiazolidin-4-ones with different C-2 and N-3 substituent groups were synthesized and evaluated as non-nucleoside reverse transcriptase inhibitors against HIV-1. This has led to new active compounds sporting heteroaryls at both C-2 and N-3 positions prompting to view them in the backdrop of nevirapine. To assign the molecular attributes for the activity, the compounds are investigated by docking them into non-nucleoside inhibitor-binding pocket of HIV-1 reverse transcriptase (RT). The most active compounds of this series (7d and 7f) shared spatial features with nevirapine with added molecular flexibility. Furthermore, in molecular dynamics simulations carried out for up to 10 ns, the compounds 7d and 7f showed consistency in their interactions with non-nucleoside inhibitor-binding pocket of HIV-1 RT and suggested Tyr319 and Val106 as potential residues for H-bond interaction with these molecules. These results open new avenues for the exploration of 2,3-diheteroaryl thiazolidin-4-ones for prevention of HIV-1.

In this study, a novel series of 4-thiazolidinone derivatives (1-17) was synthesized and evaluated for its in vitro antimicrobial and anticancer potentials. N-(2-(5-(4-nitrobenzylidene)-2-(4-chlorophenyl)-4-oxothia- zolidin-3-ylamino)-2-oxoethyl) benzamide (7, pMICam = 1.86 mu M/mL) was found to be the most active antimi- crobial agent.

Umpolung cyclization reaction of N-cinnamoylthioureas in the presence of DBU

A novel regioselective cyclization reaction of N-cinnamoylthioureas leading to six- or five-membered heterocyclic compounds was developed. N-Cinnamoylthioureas in the presence of trifluoroacetic acid (TFA) underwent the well-established intramolecular cycloaddition reaction to give 2-imino-2,3,5,6-tetrahydro-4H-1,3-thiazin-4-ones in good yields. On the other hand, the reaction with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) proceeded in an unprecedented umpolung cyclization fashion to afford five-membered 2-imino-1,3-thiazolidin-4-ones and/or 2-thioxoimidazolidine-4-ones. The reaction was considered to occur via a cycloadduct of DBU with the cinnamoyl moiety followed by intramolecular attack of the thiourea group.

Synthesis, Characterization, and Anticancer Screening of Some New Bithiazole Derivatives

Twenty new bithiazole derivatives were synthesized by condensation of 2-{2-[(1-arylethylidene)hydrazinylidene]thiazolidin-4-ylidene}hydrazine-1-carbothioamides with halo ketones, halo esters, and alpha-keto hydrazonoyl halides. The structures of all prepared compounds were proposed on the basis of their IR,H-1 and(13)C NMR, and mass spectra. All the synthesized compounds were screened for their cytotoxicity against three human cancer cell lines, HCT-116 (human colorectal carcinoma), MCF-7 (human breast adenocarcinoma), and HepG2 (human hepatocellular carcinoma). Two compounds (12dand12b) had significantly more potent anticancer activity on HCT-116 human colorectal carcinoma cells. In the case of MCF-7 human breast cancer cells, three compounds (12b,4band4a) were significantly more potent than the reference drug doxorubicin. Nine of the synthesized compounds (8a,7a,9b,12d,12c,7b,10a,5aand12b) showed a significantly higher activity than that of doxorubicin against HepG2 human liver cancer cells.

Novel thiazolidines: Synthesis, antiproliferative properties and 2D-QSAR studies

A series of N-substituted (Z)-2-imino-(5Z)-ylidene thiazolidines/thiazolidin-4-ones were synthesized and their antiproliferative activities against colon (HCT-116) and breast (MCF7) cancer cell lines were evaluated utilizing an MTT growth assay. A 2D-QSAR investigation was conducted to probe and validate the obtained antiproliferative properties for the thiazolidine derivatives. The majority of the thiazolidines exhibit higher potency against a colon cancer cell line relative to the standard reference. The p-halophenylimino p-anisylidene derivatives exhibited the highest anti-proliferative activity against HCT116 relative to control (IC50 = 8.9-10.0 mu M compared to 20.4 mu M observed for 5-fluorouracil as positive control). An X-ray study confirmed the Z, Z’-configurations for two examples of the synthesized compounds.
