An article , which mentions Synthetic Route of 2682-49-7, molecular formula is C3H5NOS. The compound – Thiazolidin-2-one played an important role in people’s production and life., Synthetic Route of 2682-49-7

In this study, a series of novel thiazolidin-4-ones (5a?g) and azetidin-2-ones (6a?g) were synthesized from N-(6-chlorobenzo[d]thiazol-2-yl)hydrazine carboxamide derivatives of the benzothiazole class. Antimicrobial properties of the title compound derivatives were investigated against one Gram (+) bacteria (Staphylococcus aureus), three Gram (?) bacteria (Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae) and five fungi (Candida albicans, Aspergillus niger, Aspergillus flavus, Monascus purpureus and Penicillium citrinum) using serial plate dilution method. The investigation of antibacterial and antifungal screening data revealed that all the tested compounds showed moderate to good inhibition at 12.5?200 mug/mL in DMSO. It has been observed that azetidin-2-ones derivatives are found to be more active than thiazolidin-4-ones derivatives against all pathogenic bacterial and fungal strains.

The Thorpe-Ingold effect is a key factor that affects the ring-closure rates and efficiency, as well as the structure of products in some ring-closure reactions. The reaction of vicinal amino primary alcohol hydrogen sulfates and carbon disulfide in the presence of potassium hydroxide produces the desired 4,4-disubstituted thiazolidine-2-thiones, and their isomers 5,5-disubstituted derivatives companying with their oxygen analogues 4,4-disubstituted oxazolidine-2-thiones. The formation of 5,5-disubstituted thiazolidine-2-thiones was rationalized via 2,2-disubstituted aziridine-1-carbodithioate intermediates, which were generated due to the Thorpe-Ingold effect. 4,4-Disubstituted oxazolidine-2-thiones were generated from carbon disulfide and free amino alcohols yielded via basic hydrolysis of active amino alcohol hydrogen sulfates in the reaction system.

A minor byproduct in the reaction of (S)-prolinol with thiophosgene in the presence of triethylamine is identified as a novel tricyclic dipyrrolidino-1,3,6-oxadiazocane-2-thione, the first example of such a ring system, and a representative of the uncommon, but useful 1,3,6-oxadiazocanes. A mechanism is proposed for its formation.

Oxidative stress and glutathione (GSH) deficit may play an important role in HIV infection pathogenesis, and oral administration of GSH- replenishing drugs such as N-acetylcysteine (NAC) and 2-oxothiazolidine-4(R)- carboxylic acid (OTC) may be associated with an increased survival rate of HIV-infected patients. Nevertheless, beneficial effects of these molecules are restricted in vivo by the high concentrations that are necessary to obtain biological effects, rapid extracellular metabolization, and low availability and plasma concentrations. We synthesized OTC derivatives that are more lipophilic than OTC and theoretically able to overcome these limitations and to generate, in addition to cysteine, other substrates of the gamma-glutamyl cycle. Their antiviral effects were investigated in human HIV- 1/ba-l-infected monocyte-derived macrophages. In our experimental conditions, OTC exhibited anti-HIV-1 effects and little cytotoxicity at high doses. None of the nine tested derivatives showed higher cytotoxicity than OTC, nor anti- HIV-1/Ba-L activity.

Cigarette/tobacco smoke/biomass fuel-induced oxidative and aldehyde/carbonyl stress are intimately associated with the progression and exacerbation of chronic obstructive pulmonary disease (COPD). Therefore, targeting systemic and local oxidative stress with antioxidants/redox modulating agents, or boosting the endogenous levels of antioxidants are likely to have beneficial effects in the treatment/management of COPD. Various antioxidant agents, such as thiol molecules (glutathione and mucolytic drugs, such as N-acetyl-L-cysteine and N-acystelyn, erdosteine, fudosteine, ergothioneine, and carbocysteine), have been reported to modulate various cellular and biochemical aspects of COPD. These antioxidants have been found to scavenge and detoxify free radicals and oxidants, regulate of glutathione biosynthesis, control nuclear factor-kappaB (NF-kappaB) activation, and hence inhibiting inflammatory gene expression. Synthetic molecules, such as specific spin traps like alpha-phenyl-N-tert-butyl nitrone, a catalytic antioxidant (ECSOD mimetic), porphyrins (AEOL 10150 and AEOL 10113), and a superoxide dismutase mimetic M40419, iNOS and myeloperoxidase inhibitors, lipid peroxidation inhibitors/blockers edaravone, and lazaroids/tirilazad have also been shown to have beneficial effects by inhibiting cigarette smoke-induced inflammatory responses and other carbonyl/oxidative stress-induced cellular alterations. A variety of oxidants, free radicals, and carbonyls/aldehydes are implicated in the pathogenesis of COPD, it is therefore, possible that therapeutic administration or supplementation of multiple antioxidants and/or boosting the endogenous levels of antioxidants will be beneficial in the treatment of COPD. This review discusses various novel pharmacological approaches adopted to enhance lung antioxidant levels, and various emerging beneficial and/or prophylactic effects of antioxidant therapeutics in halting or intervening the progression of COPD. This article is part of a Special Issue entitled: Antioxidants and Antioxidant Treatment in Disease.

COA of Formula: C3H5NOS

A series of novel 4-thiazolidinoneepyrazoline conjugates have been synthesized and tested for anti-Trypanosoma brucei activity. Screening data allowed us to identify five thiazolidinoneepyrazoline hybrids, which possess promising trypanocidal activity, with IC50 <1.2 muM. The highest active thiazolidinoneepyrazoline conjugates 3c and 6b (IC50 values of 0.6 mM and 0.7 mM, respectively) were 6-times more potent antitrypanosomal agents than nifurtimox. In addition, these compounds, as well as 6d and 6e had selectivity index higher than 50, and were more selective than nifurtimox. SAR study included substituent variations at the pyrazoline moiety, modifications of N3 position of the thiazolidinone portion, elongation of the linker between the heterocycles, as well as rhodanineeisorhodanine isomerism. It was also shown that methyl or aryl substitution at the thiazolidinone N3-position is crucial for trypanocidal activity.

A convergent stereoselective synthesis of the potent anti-inflammatory, proresolving and neuroprotective lipid mediator protectin D1 (2) has been achieved in 15% yield over eight steps. The key features were a stereocontrolled Evans-aldol reaction with Nagao’s chiral auxiliary and a highly selective Lindlar reduction of internal alkyne 23, allowing the sensitive conjugated E,E,Z-triene to be introduced late in the preparation of 2. The UV and LC/MS-MS data of synthetic protectin D1 (2) matched those obtained from endogenously produced material.
