Crystal structures of two 1,3-thiazolidin-4-one derivatives featuring sulfide and sulfone functional groups

The crystal structures of two closely related compounds, 1-cyclohexyl-2-(2-nitrophenyl)-1,3-thiazolidin-4-one, C15H18N2O3S, (1) and 1-cyclohexyl-2-(2-nitrophenyl)-1,3-thiazolidin-4-one 1,1-dioxide, C15H18N2O5S, (2), are presented. These compounds are comprised of three types of rings: thiazolidinone, nitrophenyl and cyclohexyl. In both structures, the rings are close to mutually perpendicular, with interplanar dihedral angles greater than 80 degrees in each case. The thiazolidinone rings in both structures exhibit envelope puckering with the S atom as flap and the cyclohexyl rings are in their expected chair conformations. The two structures superpose fairly well, except for the orientation of the nitro groups with respect to their host phenyl ring, with a difference of about 10 degrees between 1 and 2. The extended structure of 1 has two kinds of weak C-H center dot center dot center dot O interactions, giving rise to a closed ring formation involving three symmetryrelated molecules. Structure 2 has four C-H center dot center dot center dot O interactions, two of which are exclusively between symmetry-related thiazolidinone dioxide moieties and have a parallel ‘give-and-take-fashion’ counterpart. In the other two interactions, the nitrophenyl ring and the cyclohexane ring each offer an H atom to the two O atoms on the sulfone group. Additionally, a C-H center dot center dot center dot pi interaction between a C-H group of the cyclohexane ring and the nitrophenyl ring of an adjacent molecule helps to consolidate the structure.

Inhibition of HIV-1 RT activity by a new series of 3-(1,3,4-thiadiazol-2-yl) thiazolidin-4-one derivatives

Non-nucleoside reverse transcriptase inhibitors (NNRTIs) represent potent anti-HIV agents targeting HIV-1 reverse transcriptase (RT), a crucial enzyme for the viral life cycle. We have previously identified a series of NNRTIs bearing a 2,3-diaryl-1,3-thiazolidin-4-one core and some compounds proved to be effective in inhibiting HIV-1 replication at micromolar concentration. As a continuation in this research work we report the design, the synthesis and the structure-activity relationship studies of a further series of 3-(1,3,4-thiadiazol-2-yl)thiazolidin-4-one derivatives containing an arylthioacetamide group as pharmacophoric structural requirement for binding to the RT catalytic area. The new compounds proved to be effective to inhibit RT activity at micromolar concentrations. Finally, docking studies were carried out in order to rationalize the biological results of the new synthesized inhibitors.

Novel 4/3-((4-oxo-5-(2-oxoindolin-3-ylidene)thiazolidin-2-ylidene) amino) benzenesulfonamides: Synthesis, carbonic anhydrase inhibitory activity, anticancer activity and molecular modelling studies

Herein we report the synthesis of two series of novel 4/3-((4-oxo-5-(2-oxoindolin-3-ylidene)thiazolidin-2-ylidene)amino)benzenesulfonamides (4a-m and 7a-g). All the newly prepared sulfonamides were in vitro investigated as inhibitors of the metalloenzyme carbonic anhydrase (CA, EC 4.2.1.1) isoforms hCA I, II, IV and IX, using a stopped-flow CO2 hydrase assay. In particular, hCA isoforms II and IX (tumor associated) were more susceptible to inhibition by the synthesized derivatives, with K(1)s in the range of 2.6-598.2 nM for hCA II, and of 16.1-321 nM for hCA IX. All compounds (4a-m and 7a-g) were evaluated for their anti-proliferative activity against breast cancer MCF-7 and colorectal cancer Caco-2 cell lines. Compound 4c was found to be the most potent derivative against MCF-7 (IC50 = 3.96 +/- 0.21 mu M), while 4j was the most active member against Caco-2 cells (IC50 = 5.87 +/- 0.37 mu M). Compound 4c induced the intrinsic apoptotic mitochondrial pathway in MCF-7 cells; evidenced by the enhanced expression of the pro-apoptotic protein Bax and the reduced expression of the anti-apoptotic protein Bc1-2, and the up regulated active caspase-9 and caspase-3 levels.

SO3H-functionalized Zeolite-Y as an Efficient Nanocatalyst for the Synthesis of N-benzimidazole-2-aryl-4-thiazolidinones and tri-substituted Imidazoles

Background: SO3H-functionalized zeolite-Y was prepared and used as a catalyst for the synthesis of 2-aryl-N-benzimidazole-4-thiazolidinones and tri-substituted imidazoles at ambient conditions. Objective: The goals of this catalytic method include excellent yields and high purity, inexpensive procedure and ease of product isolation, the use of nontoxic and heterogeneous acid catalyst, shorter reaction times and milder conditions. Materials and Methods: NMR spectra were recorded on Brucker spectrophotometer using Me4Si as internal standard. Mass spectra were recorded on an Agilent Technology 5975C VL MSD with tripe-axis detector. FT-1R spectra were obtained with KBr disc on a galaxy series FT-1R 5000 spectrometer. The surface morphology of nanostructures was analyzed by FE-SEM (EVO LS 10, Zeiss, Carl Zeiss, Germany). BET analysis were measured at 196 degrees C by a Japan Belsorb H system after the samples were vacuum dried at 150 degrees C overnight. Results: The NSZ was characterized by FT-1R, FESEM, EDX, XRF, and BET. The catalytic activity of NSZ was investigated for synthesis of 1,3-tiazolidin-4-ones in H2O/Acetone at room temperature. Moreover, NSZ was used for synthesis of tri-substituted imidazoles at 60 degrees C via solvent-free condensation. Different kinds of aromatic aldehydes were converted to the corresponding of products with good to excellent yields. Conclusion: Sulfonated zeolite-Y was as an efficient catalyst for the preparation of N-benzimiclazole-2-aryl-1,3-thiazolidin-4-ones and 2,4,5-triaryl-1H-imidazoles. High reaction rates, elimination toxic solvent, simple experimental procedure and reusability of the catalyst are the important features of this protocol.

Preparation of some novel thiazolidinones, imidazolinones, and azetidinone bearing pyridine and pyrimidine moieties with antimicrobial activity

By aiming to design new antimicrobial agents, we prepared new series of thiazolidin-4-ones(12a-d), imidazolin-4-ones(13a-d), and azetidin-2-ones (14a-d), having pyridine and pyrimidine moieties. Chemical structures of these derivatives were elucidated by the use of spectral and elemental analyses. All the new substituted pyridopyrimidines were subjected to in vitro antimicrobial testing by estimating the zone of inhibition toward Bacillus subtilis and Staphylococcus aureus, as examples of bacterial species, in addition to Aspergillus flavus and Candida albicans, as examples of fungal species. The results of antimicrobial testing detected that all the screened derivatives displayed antibacterial effect; especially azetidin-2-one derivative, (14c), was the most active one. Regarding the antifungal potential, only thiazolidinone derivatives, 12a and 12c, and the imidazolinone, 13c, displayed inhibitory activity toward Aspergillus flavus, while all the tested compounds, 12a-d, 13a-d, and 14a-d, except 14a, produced inhibitory potential toward Candida albicans. Docking studies of the most active antimicrobial agents, 12c, 13c, and 14c, within GLN-6-P, recorded good scores with several binding interactions with the active site.

Molecular Structure, FT-IR, NMR (C-13/H-1), UV-Vis Spectroscopy and DFT Calculations on (2Z, 5Z)-3-N(4-Methoxy phenyl)-2-N ‘(4-methoxy phenyl imino)-5-((E)-3-(2-nitrophenyl)allylidene) thiazolidin-4-one

In this study, some molecular properties of (2Z, 5Z)-3-N(4-methoxy phenyl)-2-N'(4-methoxy phenyl imino)-5-((E)-3-(2-nitrophenyl) allylidene) thiazolidin-4-one(MNTZ) are evaluated using a combination of spectroscopic characterization (FT-IR, H-1- and C-13 NMR chemical shifts) and theoretical calculations. Molecular geometry, vibrational wavenumbers, gauge-independent atomic orbital (GIAO), H-1 and C-13 chemical shift values and NBO analysis are investigated using B3LYP and PBE functionals with the 6-31G(d,p) basis set in the ground state. The calculated geometrical parameters and vibrational spectra are compared to available experimental data and each vibrational frequency is assigned on the basis of potential energy distribution (PED). The electronic transitions are calculated using time-dependent density functional theory (TDDFT). The energy band gap between the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energies are obtained by computing the frontier molecular orbitals using the B3LYP/6-31G(d,p) and PBE/6-31G(d,p) levels along with the global reactivity descriptors. Mulliken atomic charges and molecular electrostatic potential (MEP) are simulated using both functionals to find more reactive sites for electrophilic and nucleophilic attack. Finally, the thermodynamic functions (heat capacity, entropy, and enthalpy) from spectroscopic data are obtained and discussed in the range of 100-1000 K.
