And the article was included in Chemical Research in Toxicology in 2015.Application of 444-27-9 This article mentions the following:

Carcinogenic formaldehyde is produced by endogenous protein oxidation and various exogenous sources. With formaldehyde being both ubiquitous in the ambient environment and one of the most common reactive carbonyls produced from endogenous metabolism, quantifying formaldehyde exposure is an essential step in risk assessments. The authors present in this study an approach to assess the risk of exposure to oxidative stress by quantifying thiazolidine-4-carboxylic acid (TA), a cysteine-conjugated metabolite of formaldehyde in toxicant-exposed Escherichia coli. The method entails TA derivatization with Et chloroformate, addition of isotope-labeled TA derivatives as internal standards, solid-phase extraction of the derivatives, and quantification by liquid chromatog.-mass spectrometry (LC-MS). After validating for accuracy and precision, the developed method was used to detect TA in oxidizing agent-exposed E. coli samples. Dose-dependent TA formation was observed in E. coli exposed to hydroxyl radical mediators Fe²⁺-EDTA, H₂O₂, and NaOCl, indicating the potential use of TA as a biomarker of exposure to oxidative stress and disease risk. In the experiment, the researchers used many compounds, for example, Thiazolidine-4-carboxylic acid (cas: 444-27-9Application of 444-27-9).

The effect of 2-substituted thiazolidine-4(R)-carboxylic acids on non-protein sulphydryl levels and sulphurtransferase activities in mouse liver and brain. was written by Włodek, L;Radomski, J;Wróbel, M. And the article was included in Biochemical pharmacology in 1993.SDS of cas: 16310-13-7 This article mentions the following:

2-Substituted thiazolidine-4(R)-carboxylic acids (TD) were found to increase the concentration of non-protein sulphydryls (NPSH) and the activity of rhodanese (thiosulphate sulphurtransferase, EC 2.8.1.1) and 3-mercaptopyruvate sulphurtransferase (EC 2.8.1.2) in mouse liver. These properties suggest TDs are potentially hepatoprotective compounds. However TDs also cause depletion of NPSH in the mouse brain and this may be the reason for their toxic side effects on the central nervous system.

And the article was included in European Journal of Cell Biology in 1991.Product Details of 16310-13-7 This article mentions the following:

The D-amino acid oxidase is a widely distributed peroxisomal enzyme whose principal natural substrates are still unknown. Thiazolidine carboxylates, their derivatives and relatives, and the intermediates in their metabolism are among the more plausible substrate candidates. Using a cytochem. procedure, the authors explored the distribution of peroxide-generating enzymic activity against two thiazolidine carboxylates. These compounds are effective substrates for peroxisomal oxidation in a variety of tissues that contain peroxisomal D-amino acid oxidase. Reaction was seen in the classical peroxisomes of rat liver and kidney, the peroxisomes of the fat body of firefly and of Drosophila, and the peroxisomes of frog retina. Both with the thiazolidine compounds and with more traditional D-amino acid oxidase substrates, the fireflies’ photocycle granules, which are peroxisomes, lack activity.

Reactivity of β-Amino Alcohols with Carbon Disulfide Study on the Synthesis of 2-Oxazolidinethiones and 2-Thiazolidinethiones was written by Delaunay, Dominique;Toupet, Loiec;Corre, Maurice Le. And the article was included in Journal of Organic Chemistry in 1995.Electric Literature of C6H11NS2 This article mentions the following:

Reaction of carbon disulfide with β-amino alcs. was examined to determine parameters directing the cyclization to oxazolidinethiones or thiazolidinethiones. By operating in mild conditions, i.e. in a low alk. medium, for a limited reaction time and in the presence of a stoichiometric quantity of CS₂, oxazolidinethiones were preferentially obtained. On the other hand, thiazolidinethiones were prepared under drastic conditions by operating in a more basic medium, with an excess of CS₂ and for a long reaction time. The formation of thiazolidinethiones occurred with an inversion of configuration of the carbon bearing the oxygen; furthermore, conversion of oxazolidinethiones into thiazolidinethiones was in some cases possible. In the experiment, the researchers used many compounds, for example, (S)-4-Isopropylthiazolidine-2-thione (cas: 76186-04-4Electric Literature of C6H11NS2).

Thioproline Serves as an Efficient Antioxidant Protecting Human Cells from Oxidative Stress and Improves Cell Viability was written by Ham, Yat-Hing;Jason Chan, K. K.;Chan, Wan. And the article was included in Chemical Research in Toxicology in 2020.Recommanded Product: 444-27-9 This article mentions the following:

Oxidative stress is associated with the pathophysiol. of many degenerative human diseases, including Alzheimer′s disease, atherosclerosis, Parkinson′s disease, and cancers. We discovered in our previous study that thioproline (SPro), a proline analog, is generated in oxidant-exposed cells. With the prior observation that SPro served as an efficient nitrile trapping agent, we tested in this study the hypothesis that this oxidative stress generated cysteine-formaldehyde adduct, SPro, may serve as an antioxidant protecting cells from oxidative stress. Interestingly, results showed that HeLa cells cultured in SPro-supplemented culture media are more tolerant of oxidative stress, indicated by a dosage-dependent increase in cell viability. Investigation of the mol. mechanism of the observed increase in cell tolerance to oxidative stress revealed SPro acting as an effective antioxidant by sacrificial oxidation Results also showed that SPro had been incorporated into cellular proteins and induced changes in protein expression profiles of treated cells. Despite being yet to determine the participation of individual factors to the observed increase of cell tolerance to oxidative stress, this study sheds light on the potential use of SPro as a dietary supplement for protecting humans from oxidative stress-associated degenerative human diseases.

Stereoselective Hydrocoupling of Optically Active 3-trans-Cinnamoyloxazolidinones by Electroreduction was written by Kise, Naoki;Mashiba, Syun-ichiro;Ueda, Nasuo. And the article was included in Journal of Organic Chemistry in 1998.Related Products of 76186-04-4 This article mentions the following:

Reductive hydrocoupling of chiral 3-trans-cinnamoyloxazolidinones was studied by an electrochem. method. The electroreduction was performed conveniently at a constant current using an undivided cell. The stereoselectivity of the hydrodimers was strongly affected by the electrolyte employed. Electroreduction of (S)-4-isobutyl-3-trans-cinnamoyloxazolidinone (I) in 0.3 M Et₄NOTs/AN gave a mixture of two diastereomers of all-trans cyclized hydrodimer, and the selectivity was R,S,R/S,R,S = 85:15. On the other hand, the reduction of I in 1.7 M LiClO₄/THF afforded a diastereomeric mixture of hydrodimers in a selectivity of R,R/S,S/R,S = 5:52:43. The stereoselectivities were explained by considering stable conformations of intermediate anion radicals, i.e., syn-Z type for naked anion radicals and anti-Z type for lithiated anion radicals. Semiempirical calculations also supported this hypothesis. Electroreductions of (S)-4-isobutyl-3-cis-cinnamoyloxazolidinone and (S)-4-isobutyl-3-phenylpropioloyloxazolidinone gave the same stereoselectivity as electroreduction of I did. The electroreductive hydrocoupling was not inhibited by para and meta substitution on the aryl group of 3-trans-cinnamoyloxazolidinones. An ortho substitution, however, hindered the hydrocoupling and lowered the stereoselectivity of the hydrodimers. Electroreduction of 3-trans-cinnamoyloxazolidinethione and thiazolidinethione gave trans-3,4-diphenylcyclopentanone as a product, and the stereoselectivities were similar to that obtained from the corresponding oxazolidinone.
