Synthesis of tetracyclic azasugars fused benzo[e][1,3]thiazin-4-one by the tandem Staudinger/aza-Wittig/cyclization and their HIV-RT inhibitory activity

Azasugar aldehydes 6a and 6b containing azido groups were prepared from D-mannose. Three novel tetracyclic azasugars fused benzo[e][1,3] thiazin-4-one 9a-1, 9a-2 and 9a-3 were conveniently synthesized from 6a by the tandem intramolecular Staudinger/aza-Wittig/cyclization reaction under microwave radiation. Two unexpected elimination compounds 8b-1 and 8b-2 were achieved as the main products from 6b in the same processes. The newly synthesized azasugars were examined for their HIV reverse transcriptase (RT) inhibitory activities. The results showed that all the tested compounds could effectively inhibit RT activity. Among them, compound 8b-1 with the protective group (isopropylidene group) was the best one with the IC50 value of 0.76 mu M. The structure activity relationship analysis suggested that improvement of the molecular hydrophilicity might be beneficial for their anti-HIV RT activities. (C) 2017 Elsevier Ltd.

The antinociceptive evaluation of 2,3-substituted-1,3-thiazolidin-4-ones through thermal stimulation in mice

The present study assessed the 2,3-substituted-1,3-thiazolidin-4-ones antinociceptive potential looking at the acute nociception model induced by thermal stimulation in mice. This was done to contribute to the development of new analgesic drugs, in addition to the fact that 4-thiazolidinones are an important scaffold associated with many pharmacological activities. The synthesized compounds were characterized by GC-MS and NMR of H-1 and C-13 and administered at a dose of 100 mg/kg hydrochloride salt (ip). Sodium dipyrone (250 and 500 mg/Kg; ip) and tramadol hydrochloride (25 and 50 mg/Kg; ip) were used as positive controls. The hot plate test was done at a temperature of 50 +/- 0.1 degrees C and animals assessed at 30, 60, and 90 min after the drugs were administered. Among the fourteen compounds tested, nine (5Aa, 5Ab, 5Ac, 5Ad, 5Ba, 5Bb, 5Bd, 5Ea, and 5Fa) showed significant increases in latency time when compared to saline (negative control) and compared to sodium dipyrone (500 mg/Kg; ip) in a 30-min assessment. The highest latency times were obtained for 3-(2-piperidin-1-yl)ethyl)thiazolidin-4-one derivatives (5Ab, 5Ac, and 5Ad). This highlights three findings about the chemical structure that improve activity: (i) an ethylenic link; (ii) a six-membered piperidine; (iii) an aliphatic substituent at the 2-position of thiazolidinone ring.

Condensation-cyclization reaction for one-pot synthesis of 1,3-thiazolidin-4-one derivatives by poly(p-phenylenediamine) grafted on LDHs as a catalyst with green tool

The three-component reaction between amine, carbonyl compound and thioglycolic acid is now considered as a major strategy for synthesis of 1,3-thiazolidin-4-ones, which consists of the following steps: (i) condensation of aldehyde and amine which results the formation of an imine; (ii) the reaction between thioglycolic acid and the imine which is followed by an intramolecular cyclization reaction, which leads to the formation of the final product. In this way, if no suitable catalyst is employed, the completion of the reaction will not be achieved. Hence, it is of great importance to select an appropriate catalyst so that these compounds can be successfully synthesized. Herein, we employed LDHs@PpPDA as a versatile catalyst for the fabrication of novel derivatives of 1,3-thiazolidin-4-one.

Electric Literature of 99-86-5, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 99-86-5 is helpful to your research.

Insulin stimulus-secretion coupling is triggered by a novel thiazolidinedione/sulfonylurea hybrid in rat pancreatic islets

New compounds with promising antidiabetic activity were synthesized. For the first time, a portion of the glibenclamide molecule was bound to a part of the core structure of thiazolidinedione to evaluate insulin secretagogue activity. Following studies in our laboratory, 4-{2-[2-(3,4-dichlorophenyl)-4-oxo-1,3-thiazolidin-3-yl]ethyl}benzene-1-sulfonamide (DTEBS) was selected to evaluate glycemia using the glucose tolerance test and insulin secretagogue activity by E.L.I.S.A. The mechanism of action of this compound was studied by Ca-45(2+) influx and whole-cell patch-clamp in rat pancreatic isolated islets. Furthermore, AGE formation in vitro was investigated. We herein show that this novel hybrid compound (DTEBS) exhibits an insulinogenic index and a profile of serum insulin secretion able to maintain glucose homeostasis. Its mechanism of action is mediated by ATP-sensitive potassium channels (KATP) and L-type voltage-dependent calcium channels (VDCC) and by activating protein kinase C and A (PKC and PKA). In addition, the stimulatory action of the compound on calcium influx and insulin secretion indicates that the potentiation of voltage-sensitive K+ currents (Kv) is due to the repolarization phase of the action potential after secretagogue excitation-secretion in pancreatic islets. Furthermore, under these experimental conditions, the compound did not induce toxicity and the in vitro late response of the compound to protein glycation reinforces its use to prevent complications of diabetes. DTEBS exerts an insulin secretagogue effect by triggering KATP, VDCC, and Kv ionic currents, possibly via PKC and PKA pathway signal transduction, in beta-cells. Furthermore, DTEBS may hold potential for delaying the late complications of diabetes.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 99-86-5. Category: thiazolidines.

An iron( III) complex selectively mediated cancer cell death: crystal structure, DNA targeting and in vitro antitumor activities

The design, synthesis, crystal structures and in vitro biological assessment of three iron(iii) complexes, namely [Fe(L1)(2)]Cl (1), [Fe(L2)(2)]FeCl4 (2) and [Fe(L3)(HL3)(2)](FeCl4)(2)(CH3OH) (3) (HL1 = N’-(4-oxothiazolidin-2-ylidene)picolinohydrazonamide, HL2 = 2-(2-(1-(pyridin-2-yl)ethylidene)hydrazono)thiazolidin-4-one, HL3 = 3-ethyl-2-(2-(1-(pyridin-2-yl)ethylidene)hydrazono)thiazolidin-4-one, are reported in this article. Single crystal X-ray diffraction revealed that all three complexes were mononuclear molecules, approaching a coordination polyhedron of octahedral geometry, in which the 4-thiazolidinone derivative ligands exhibited different coordination modes and conformations. Their interactions with DNA were investigated by UV-visible and fluorescence spectrometries, and by agarose gel electrophoresis. Results indicated that they presented efficient DNA binding propensities and cleavage activities. In vitro, the iron(iii) complexes caused cell cycle arrest at the G1 phase in response to DNA damage, effectively inhibited the cyclinD1 expression and decreased the migration of HeLa cells with a lower wound-healing rate than that of the control. Complex 3 was the most sensitive to HeLa cancer cells, followed by 2 and 1. Attractively, the tested complexes demonstrated significantly enhanced selectivity index values determined for HeLa vs. LO2 normal cells compared with cisplatin, especially for complex 3, which was up to 13.94-fold. Unlike cisplatin, more complex 3 would accumulate in HeLa cancer cells compared with LO2 normal cells.
