Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. In a patent, 76186-04-4, name is (S)-4-Isopropylthiazolidine-2-thione, introducing its new discovery. category: thiazolidine

The first diastereoselective synthesis of aryloxyphosphoramidate prodrugs of 3?-deoxy-2?,3?-didehydrothymidinemonophosphate (d4TMP) was recently reported. The synthetic approach utilized the chiral auxiliary (S)-4-isopropylthiazolidine-2-thione (2). For this strategy, a stereochemically pure phosphorodiamidate intermediate was needed. The diastereoselective formation of this key compound was investigated by using different phenols and L-alanine methyl or benzyl ester. Generally, the reaction with 3- or 4-substituted phenols led to significantly better diastereoselectivities compared to their 2-substituted counterparts. Moreover, variation of the ester group in the amino acid residue resulted in no significant differences with regard to the obtained diastereoselectivity. From the reported results, a model for the transition state was elaborated. Finally, eight new (S P)-arylphosphoramidates were synthesized with very high diastereoselectivities (up to ? 95 % de) and tested for their anti-HIV potency, showing a tendency for higher antiviral activity from the (S P) diastereomers.

Cervical cancer ranks third among the most prevalent deadly cancer in women worldwide and ranks first in developing countries. It is caused by human papilloma virus (HPV) infection. Thus HDACs have become prominent inhibition target for cervical cancer treatment. In order to discover the new alternative HDAC inhibitors (HDACIs), we conducted a computer-aided drug discovery and development (CADDD) based on de novo approach. The compound library is based on 4-[(2-oxo-1,3-thiazolidin-3-yl)carbonyl] aniline. Screening of the best drug leads was evaluated from several parameters, such as docking and interaction analysis, pharmacology, in silico preclinical trial and molecular dynamics analysis. The inhibitory activity of these new designed ligands against Homo sapiens class II HDAC was determined by molecular docking simulation. Docking analysis yielded eight best ligands which have better binding affinity than the standards. Therefore, interaction analysis indicated that all best ligands performed coordination with Zn2+ cofactor in HDAC charge-relay system which are essential for HDAC inhibitory activities of these inhibitors. Pharmacology analysis and preclinical trials of these compounds including pharmacology properties, bioactivity, mutagenicity?carcinogenicity, absorption, distribution, metabolism, excretion and toxicity (ADMET) properties were done through in silico methods. Through this analysis, the best ligands meet Lipinski’s rule of five, have a better drug score than standards, and show good bioactivities, oral bioavailability and ADMET properties. All best ligands also have good synthetic accessibility and were proved to be new compounds that have never been synthesized before. Stability of HDAC?ligand complexes was also calculated through molecular dynamics (MD) simulation. Based on this simulation, complex of the best ligands with corresponding HDAC has a good stability based on RMSD (root mean square deviation) and interaction analysis. The study thus reveals eight best ligands (F, Ib14, O38, Kb17, Gd40, Aa50, Gc42 and Bb38) which have better binding affinity against human class II histone deacetylase (HDAC) through molecular docking, dynamics and interaction analysis. The best ligands were also found to have good bioactivities, oral bioavailability and ADMET properties through in silico pharmacology analysis and preclinical trial. These compounds were found to have a good synthetic accessibility; therefore they could be synthesized for further biological and clinical test.

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, name: Thiazolidin-2-one, 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 an attempt to identify potential new agents active against tuberculosis with Shikimate kinase as the target, a novel series of 2-phenyl- 3-(5-sulfanyl-1,3,4-thiadiazol-2-yl)-1,3-thiazolidin-4-one derivatives were synthesized by convenient one-pot three-component reaction of amine, aldehyde and mercaptoacetic acid on montmorillonite KSF clay as a solid acidic catalyst in good yields. The structures of the newly synthesized compounds were confirmed by IR, 1H-NMR and elemental analysis and were subjected for anti-tubercular activity by Microplate Alamar Blue Assay (MABA) against Mycobacterium tuberculosis H37Rv. Docking and ADMET studies were used to better describe the titled compounds as potential anti-tubercular agents. The compound, 2-(3,4-dimethoxyphenyl)-3-(5-sulfanyl-1,3,4-thiadiazol-2-yl)-1,3-thiazolidin-4-one(4j), was found to be the most active against Mycobacterium tuberculosis H37Rv with MIC of 1.6 mug/ml and good drug likeness and dock scores. Molecular docking study revealed that the molecules fit well into the cavity of Shikimate kinase. Also, the molecular properties and bioactivity scores for the synthesized compounds obtained by in-silico studies were found to be within the acceptable range defined for human use revealing their potential as possible drug-like compounds. The anti-tubercular activity of the titled compounds was comparable to that of the standard drug Isoniazid and Ciprofloxacin. The results indicate that the synthesized thiadiazolyl-thiazolidinone derivatives may have an affinity towards Shikimate kinase active site which can be further explored for selective target based studies. Thus these compounds could act as a potential lead for further anti-tubercular studies.
