SYNTHESIS, ANTIMICROBIAL, ANTICANCER EVALUATION AND QSAR STUDIES OF THIAZOLIDIN-4-ONE DERIVATIVES

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. The anticancer study results demonstrated that N-(2-(5-(4-hydroxybenzylidene)-2-(4- methoxyphenyl)-4-oxothiazolidin-3-ylamino)-2-oxoethyl) benzamide (10, IC50 = 18.59 mu M) was the most active anticancer agent. QSAR studies indicated the importance of topological parameter, Kier’s alpha third order shape index (k alpha(3)) as well as electronic parameters, cosmic total energy (cos E) and energy of highest occupied molecular orbital (HOMO) in describing the antimicrobial activity of synthesized compounds.

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.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 6117-80-2, you can contact me at any time and look forward to more communication. HPLC of Formula: C4H8O2.

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.

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

Synthesis and Antimicrobial Screening of Novel Azetidin-2-ones Derived from Pyromellitic Diimide via [2+2]-Cycloaddition Reaction

A series of novel 2-azetidinone derivatives have been obtained starting from pyromellitic dianhydride. Pyromellitic dianhydride was converted to pyromellitic diimide using sodium cyanate, and the diimide was alkylated with ethyl chloroacetate. The resulting diester was treated with hydrazine hydrate to obtain dihydrazide which reacted with substituted pyridine-2-carbaldehydes to give the corresponding Schiff bases, and [2+2]-cycloaddition of the latter with chloroacetyl chloride in the presence of triethylamine afforded the target azetidin-2-one derivatives. The newly synthesized compounds showed high antimicrobial activities against some bacterial and fungal strains.

Linear and nonlinear optical properties of new azo aminosalicylic acid derivatives

4-(3-Allyl-4-oxo-2-thioxo-thiazolidin-5-ylazo) salicylic acid (4-ATS) and 5-(3-allyl-4-oxo-2-thioxo-thiazolidin-5ylazo) salicylic acid (5-ATS) were synthesized and characterized by different spectroscopic techniques. The XRD patterns of 4-ATS and 5-ATS in powder form were recorded and found to be polycrystalline with monoclinic crystal system. Thin films of 4-ATS and 5-ATS were successfully prepared by thermal evaporation technique onto optical flat quartz substrates. Linear and nonlinear optical properties of 4-ATS and 5-ATS were investigated by spectrophotometric measurements. The spectral distribution of refractive index of 5-ATS thin films showed normal dispersion in the non-absorbing region of spectra, while 4-ATS showed nonlinear response. The optical energy gap and the electronic transition type for 4-ATS and 5-ATS were calculated. The electronic absorption and emission spectra were recorded for pristine and UV-irradiated 4-ATS and 5-ATS thin films. The absorption coefficient spectra for 4-ATS and 5-ATS were found to decrease with increasing UV exposure time, while the intensity of emission spectra for both of the derivatives were enhanced with increasing UV exposure time. Recovery in dark reversed the effect of UV-radiation.
