Synthesis, characterization and acute anti-inflammatory evaluation of new mefenamic acid derivatives having 4-thiazolidinone nucleus

Mefenamic acid (MA) is one of the non-steroidal anti-inflammatory drugs, it is widely used probably due to having both anti-inflammatory and analgesic activity, the main side effects of mefenamic acid include gastrointestinal tract (GIT) disturbance mainly diarrhea, peptic ulceration, and gastric bleeding. The analgesic effects of NSAIDs are probably linked to COX-2 inhibition, while COX-1 inhibition is the major cause of this classic adverse effects. Introduction of thiazolidinone may lead to the increase in the bulkiness leads to the preferential inhibition of COX-2 rather than COX-1 enzyme. The study aimed to synthesize derivatives of mefenamic acid with more potency and to decrease the drug’s potential side effects, new series of 4-thiazolidinone derivatives of mefenamic acid were synthesized IVa-g. The synthetic procedures for target compounds and their intermediates are designed to be as follows: Acylation of secondary amine of mefenamic acid by chloroacetylchloride to produce compound (I), then reaction between compound (I) and hydrazine hydrate to form hydrazine derivative of mefenamic acid (compound II). After that, Schiff base formation by addition of seven benzaldehyde derivatives and finally, cyclization in presence of thioglycolic acid to form 4-thiazolidinone heterocyclic ring. The characterization of the titled compounds has been established on the basis of their spectral FTIR, 1HNMR data, and by measurements of their physical properties. In vivo acute anti-inflammatory effect of the synthesized compounds was evaluated in rats using egg-white induced edema model of inflammation. The tested compounds and the reference drug produced significant reduction of paw edema with respect to the effect of dimethyl sulfoxide 10%v/v (control group). Compound IVe showed more potent effect than mefenamic acid at 240-300 min, while at time 300 min, compounds IVa and IVd exhibit more potent anti-inflammatory effect than mefenamic acid (50mg/kg, i.p.) as they reduced paw edema significantly more than mefenamic acid at mentioned intervals (p<0.05) . On the other hand compound IVc exhibited lower anti-inflammatory effect. One of the oldest and most widely used commercial enzyme inhibitors is aspirin, Recommanded Product: 2682-49-7, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 2682-49-7

In Vivo Selective Modulation of Tissue Glutathione in a Rat Mammary Carcinoma Model

Glutathione (GSH) is known to play a role in cellular sensitivity to some chemotherapeutic agents and to radiation. Depletion of cellular GSH has been demonstrated to result in enhanced toxicity of these drugs, and this approach is being explored in the clinic as a form of biochemical modulation, using the drug buthionine sulfoximine (BSO). The fact that some drug-resistant cell lines have increased glutathione levels, and that enhancing GSH concentrations in animal tissues protects against a variety of xenobiotic agents, suggest a different potential approach to improving anti-cancer therapy. We have examined the efficacy of the cysteine “pro-drug” L-2-oxothiazolidine-4-carboxylate (OTZ) at enhancing normal tissue versus tumor GSH. Animals were treated with OTZ or BSO, and the concentrations of GSH in normal tissues and tumor were measured. We found that the presence of the tumor itself decreased bone marrow GSH, but that OTZ significantly increased it in this setting. Interestingly, OTZ administration significantly depleted tumor GSH levels to the same level as did BSO. OTZ could offer a selective biochemical modulation of GSH.

Design, Synthesis and Biological Evaluation of 2-(naphthoyl) iminothiazolidin-4-ones as Potential Anticancer Agents

A library of novel naphthyl bearing 2-iminothiazolidin-4-ones (2-ITZDs) (2 a?2 q) was designed and synthesized through a facile route involving regioselective heterocyclization of unsymmetrical thioureas (1 a?1 q). The synthesis was achieved at ambient temperature in good to excellent yields under catalyst free conditions. The molecular structures of 2-ITZDs were elucidated by spectroscopic techniques such as FT-IR, 1H-NMR and 13C-NMR. X-ray structural data was used to establish the structure (2 o) unequivocally and to define the geometry of exo double bond. The in vitro anticancer activity of 2-ITZDs (2 a?2 q) was investigated in several human cancer cell lines (A549, LNCap, PC-3, MDA-MB-231, BxPC3, MIA PaCa2). All compounds showed cytotoxicity with IC50 values ranging from 6?23 muM in the tested cancer cell lines except MDA-MB-231. Compound 2 k (IC50=7 muM) and the homologous analog 2 q (IC50=6 muM) were found to be equipotent to 2 k and showed moderate cytotoxicity against human breast cell line (DA-MB-231). Furthermore, compound 2 k exhibited a medium permeability, enough metabolic stability and no significant inhibition of hERG channel. Compound 2 k inhibited cytochrome P450 activity below 50 % in 1 A2, 3 A4 and 2 C19, but not in 2 C9 and 2D6 at 10 muM. Structure-activity relationships (SAR) provided useful insights towards this class of compounds and tiled a way to design novel analogues with increased potency.

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 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 between 1 and 2. The extended structure of 1 has two kinds of weak C – H?O interactions, giving rise to a closed ring formation involving three symmetry-related molecules. Structure 2 has four C – H?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?pi interaction between a C – H group of the cyclohexane ring and the nitrophenyl ring of an adjacent molecule helps to consolidate the structure.

Synthesis and evaluation of anticonvulsant activities of 5-benzylidene-2-(5-methylisoxazol-3-ylimino)thiazolidin-4-one derivatives

Fifteen new 5-benzylidene-2-(5-methylisoxazol-3-ylimino)thiazolidin-4-one derivatives (4-18) were synthesized and evaluated for their preliminary anticonvulsant activity and neurotoxicity by using the maximal electroshock (MES) and rotarod tests. The structures of synthesized compounds were established by IR,1H NMR,13C NMR and mass spectral data. Among the compounds studied, 5-(3-fluorobenzylidene)-2-(5-methylisoxazol-3-ylimino)thiazolidin-4-one (8) was the most potent compound, with a median effective dose of 43.9 mg/kg and a high protective index (PI) of more than 11.1 after intraperitoneal administration in mice. Compound 8 showed significant oral activity against MES-induced seizures in mice, with an ED50 of 84.2 mg/kg and a PI above 11.8. These results demonstrate that compound 8 is safer than the commercially drugs.

Organocatalytic Cyclization of COS and Propargylic Derivatives to Value-Added Heterocyclic Compounds

The organocatalytic cyclization of propargylic amines/amides with carbonyl sulfide (COS) was firstly achieved by employing COS adducts of Lewis base (LB) as organocatalysts, affording various functionalized 1,3-thiazolidine-2-ones, and 1,3-thiazolidine-2,4-diones derivatives in a highly chemo- and stereoselective manner. The isotope labeling and stoichiometric experiments suggested the LB-COS adducts preferentially mediated basic ionic pair mechanism. Furthermore, the practical application of this methodology was highlighted by the highly efficient synthesis of rosiglitazone using COS as sulfur source.
