Luminescence feature of new 3,6-di(thiazolidin-5-one-2-yl)-carbazole derivative: synthesis, photophysical properties, density functional theory studies, and crystal shape effect

A new carbazole chromophore conjugated with substituted thiazolidine-4-one (CzPT) was synthesized by applying the Knoevenagel reaction between 3,6-diformyl-N-hexylcarbazole and ethyl 2-aceto-2-(5-oxo-3-phenylthiazolidin-2-ylidene)acetate. The chemical structure of the new derivative (CzPT) was elucidated by spectral studies. The CzPT absorption spectra in different solvents exhibited a red shift for lambda(max) by increasing solvent polarity. Bands at 430-474 nm appeared and were attributed to intramolecular charge transfer with high pi-pi* characteristics. CzPT fluorescence spectra exhibited a red shift after increasing the solvent polarity. To understand the Stokes’ shift (increment nu over bar ) behaviour of the CzPT derivative referring to the polarity of solvents, Lippert-Mataga and linear solvation-energy relationship (LSER) models were employed in which the LSER exhibited respectable results compared with Lippert-Mataga (r(2) = 0.9707). Moreover, time-dependent density functional theory absorption spectra in hexane and dimethylformamide showed that lambda(max) had a major contribution in the highest occupied molecular orbital to lowest unoccupied molecular orbital transition in both solvents. In addition, the reduced uniformity of crystal features may lead to dislocation or anomalous arrangement of crystals with irregular spacing, which automatically enhances the optical properties of such crystals.

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 83237-15-4, in my other articles.

Further insight into the dual COX-2 and 15-LOX anti-inflammatory activity of 1,3,4-thiadiazole-thiazolidinone hybrids: The contribution of the substituents at 5th positions is size dependent

Herin we report the design, synthesis, full characterization and biological investigation of new 15-LOX/COX dual inhibitors based on 1,3-thiazolidin-4-one (15-lipoxygenase pharmacophore) and 1,3,4-thiadiazole (COX pharmacophore) scaffolds. This series of molecular modifications is an extension of a previously reported series to further explore the structural activity relationship. Compounds 3a, 4e, 4n, 4q, 7 and 8 capable of inhibiting 15-LOX at (2.74, 4.2, 3.41, 10.21, 3.71 and 3.36 mu M, respectively) and COX-2 at (0.32, 0.28, 0.28, 0.1, 0.28 and 0.27 mu M, respectively). The results revealed that binding to 15-LOX and COX is sensitive to the bulkiness of the substituents at the 5 positions. 15-LOX bind better with small substituents, while COXs bind better with bulky substituents. Compounds 3a, 4r and 4q showed comparable in vivo anti-inflammatory activity to the reference drug (celecoxib). The ulcer liability test showed no sign of ulceration which ensures the safe gastric profile. Docking study was performed to explore the possible mode of interaction of the new compounds with the active site of human 15-LOX and COX-2. This study discloses some structural features for binding to 15-LOX and COX, thus pave the way to design anti-inflammatory agents with balanced dual inhibition of these enzymes.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 115-96-8, you can contact me at any time and look forward to more communication. Quality Control of Tris(2-chloroethyl) phosphate.

Visible-light-driven photocatalytic activity of ZnO/g-C3N4 heterojunction for the green synthesis of biologically interest small molecules of thiazolidinones

Designing a photocatalytic system with complementary properties including high surface area, high loading, extraordinary electronic properties, and easy separation for increases photocatalytic performance has remained a challenge in photocatalytic applications. Herein, an environmentally benign approach was developed to fabricate graphitic carbon nitride (g-C3N4) decorated with nanorods zinc oxide (ZnO). The photocatalytic activity of ZnO decorated on the g-C3N4 surface was developed in the synthesis of 1,3-thiazolidin-4-ones and bis-thiazolidinones under very mild and sustainable reaction conditions. The reaction can be carried out by utilizing visible light without the requirement of any additive and other external sources of energy. It was found that the proposed photocatalyst is a more facile, recyclable, large-scale application and provides some new insights into the stabilization of semiconductors for a variety of applications.

SYNTHESIS AND EVALUATION OF ANTI-PROLIFERATIVE ACTIVITY OF NOVEL THIAZOLIDINONE DERIVATIVES

A series of, 2-thioxo-4-thiazolidinone (rhodanine) and 2,4-thiazolidine-dinone derivatives were synthesized by reacting 4-thiazolidine-dione/rhodanine moieties with 2-(4-formylphenoxy)-N-substituted-phenyl-acetamide, in equimolar proportions. The authentication of synthesized compounds was done by FTIR, (HNMR)-H-1, and mass spectrophotometry. The derivatives, N-(phenyl) -2- {4-[(4-oxo-2-thioxo-1, 3-thiazolidin-5-ylidene) methyl] phenoxy} acetamide and 2-{4-[(2,4-dioxo-1,3-thiazolidin-5-ylidene)-methyl] phenoxy}-N-(phenyl)-acetamide, were further screened for their anticancer properties against CEM cell lines. Cell viability was determined by trypan blue dye exclusion assay and cytotoxic effect of the compounds by MTT assay. The two derivatives, N-(phenyl)-2-{4-[(4-oxo-2-thioxo-1,3-thiazolidin-5-ylidene) methyl] phenoxy} acetamide and 2-{4-[(2,4-dioxo-1,3-thiazolidin-5-ylidene)-methyl] phenoxy}-N-(phenyl)-acetamide were found to be anti-proliferative in nature at 75 – 100 mu M and 100 – 250 mu M concentrations, respectively. Thus, it can be established that the rhodanine derivatives, N-(phenyl) -2-{4-[(4-oxo-2-thioxo-1, 3-thiazolidin-5-ylidene) methyl]-phenoxy} acetamide and 2-{4-[(2,4-dioxo-1,3-thiazolidin-5-ylidene) methyl] phenoxy}-N-(phenyl)-acetamide have anti-proliferative property against leukemic cell lines (lymphoblastic leukemia) and can be further optimized to improve its efficacy and safety.

Genetic and small molecule inhibition of arylamine N-acetyltransferase 1 reduces anchorage-independent growth in human breast cancer cell line MDA-MB-231

Arylamine N-acetyltransferase 1 (NAT1) expression is reported to affect proliferation, invasiveness, and growth of cancer cells. MDA-MB-231 breast cancer cells were engineered such that NAT1 expression was elevated or suppressed, or treated with a small molecule inhibitor of NAT1. The MDA-MB-231 human breast cancer cell lines were engineered with a scrambled shRNA, a NAT1 specific shRNA or a NAT1 overexpression cassette stably integrated into a single flippase recognition target (FRT) site facilitating incorporation of these different genetic elements into the same genomic location. NAT1-specific shRNA reduced NAT1 activity in vitro by 39%, increased endogenous acetyl coenzyme A levels by 35%, and reduced anchorage-independent growth (sevenfold) without significant effects on cell morphology, growth rates, anchorage-dependent colony formation, or invasiveness compared to the scrambled shRNA cell line. Despite 12-fold overexpression of NAT1 activity in the NAT1 overexpression cassette transfected MDA-MB-231 cell line, doubling time, anchorage-dependent cell growth, anchorage-independent cell growth, and relative invasiveness were not changed significantly when compared to the scrambled shRNA cell line. A small molecule (5E)-[5-(4-hydroxy-3,5-diiodobenzylidene)-2-thioxo-1,3-thiazolidin-4-one (5-HDST) was 25-fold more selective towards the inhibition of recombinant human NAT1 than N-acetyltransferase 2. Incubation of MDA-MB-231 cell line with 5-HDST resulted in 60% reduction in NAT1 activity and significant decreases in cell growth, anchorage-dependent growth, and anchorage-independent growth. In summary, inhibition of NAT1 activity by either shRNA or 5-HDST reduced anchorage-independent growth in the MDA-MB-231 human breast cancer cell line. These findings suggest that human NAT1 could serve as a target for the prevention and/or treatment of breast cancer.

Novel Benzylidene Thiazolidinedione Derivatives as Partial PPAR gamma Agonists and their Antidiabetic Effects on Type 2 Diabetes

Peroxisome proliferator-activated receptor gamma (PPAR gamma) has received significant attention as a key regulator of glucose and lipid homeostasis. In this study, we synthesized and tested a library of novel 5-benzylidene-thiazolidin-2,4-dione (BTZD) derivatives bearing a substituent on nitrogen of TZD nucleus (compounds 1a-1k, 2i-10i, 3a, 6a, and 8a-10a). Three compounds (1a, 1i, and 3a) exhibited selectivity towards PPAR. and were found to be weak to moderate partial agonists. Surface Plasmon Resonance (SPR) results demonstrated binding affinity of 1a, 1i and 3a towards PPAR gamma. Furthermore, docking experiments revealed that BTZDs interact with PPAR gamma through a distinct binding mode, forming primarily hydrophobic contacts with the ligand-binding pocket (LBD) without direct H-bonding interactions to key residues in H12 that are characteristic of full agonists. In addition, 1a, 1i and 3a significantly improved hyperglycemia and hyperlipidaemia in streptozotocin-nicotinamide (STZ-NA)-induced diabetic rats at a dose of 36 mg/kg/day administered orally for 15 days. Histopathological investigations revealed that microscopic architecture of pancreatic and hepatic cells improved in BTZDs-treated diabetic rats. These findings suggested that 1a, 1i and 3a are very promising pharmacological agents by selectively targeting PPAR. for further development in the clinical treatment of type 2 diabetes mellitus.
