Cysteamine was condensed with glyoxylic acid monohydrate in a mixture of acetic acid and ethanol in the presence of (2R,3R)- or (2S,3S)-tartaric acid [(R)- or (S)-TA], as the resolving agent, to give the salt of (-)-2-thiazolidinecarboxylic acid [(-)-2-THC] with (R)-TA or the salt of (+)-2-THC with (S)-TA. Treatment of these salts with triethylamine in methanol afforded (-)- and (+)-2-THC, I and II resp. I and II were determined to be enantiopure forms by comparing their powder X-ray diffraction patterns with that of (RS)-2-THC. The absolute configurations of I and II were estimated based on molar rotations of (2R,4R)- and (2S,4R)-2,4-thiazolidinedicarboxylic acids, (R)-4-thiazolidinecarboxylic acid, and I and II. I was determined to have the (R)-configuration with II having the (S)-configuration.

Cysteine reacts with reactive carbonyls to form thioprolines, which have been demonstrated to possess various pharmaceutical properties. Therefore, thioproline formation is considered as a major detoxification pathway for carcinogenic reactive carbonyls. In this study, we report the initial identification of thiazolidine-4-carboxylic acid (1) and 2-methylthiazolidine-4-carboxylic acid (2), two very common thioprolines, formed by reacting formaldehyde and acetaldehyde with cysteine in grape wine samples. We have developed an isotope dilution-liquid chromatog.-tandem mass spectrometry method featuring high sensitivity (limit of detection of ≤1.5 ng/mL) and selectivity to quantitate compounds 1 and 2. The method after validated to be highly accurate (recovery of ≥92%) and precise [intraday relative standard deviation (RSD) of ≤4.1% and interday RSD of ≤9.7%] was applied to determine the varying compound 1 and 2 contents in grape wine samples. Results revealed the grape type and storage duration-dependent formation of thioprolines in grape wines.

Diastereoselective Synthesis of (Aryloxy)phosphoramidate Prodrugs was written by Arbelo Roman, Cristina;Wasserthal, Philip;Balzarini, Jan;Meier, Chris. And the article was included in European Journal of Organic Chemistry in 2011.Recommanded Product: 76186-04-4 This article mentions the following:

The first diastereoselective synthesis of aryloxyphosphoramidate prodrugs of 3′-deoxy-2′,3′-didehydrothymidine monophosphate (d4TMP) was recently reported. The synthetic approach utilized the chiral auxiliary (S)-4-isopropylthiazolidine-2-thione. For this strategy, a stereochem. pure phosphorodiamidate intermediate was needed. The diastereoselective formation of this key compound was investigated by using different phenols and L-alanine Me 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. In the experiment, the researchers used many compounds, for example, (S)-4-Isopropylthiazolidine-2-thione (cas: 76186-04-4Recommanded Product: 76186-04-4).

SELENOPROTEIN O is a chloroplast protein involved in ROS scavenging and its absence increases dehydration tolerance in Arabidopsis thaliana was written by Fichman, Yosef;Koncz, Zsuzsa;Reznik, Noam;Miller, Gad;Szabados, Laszlo;Kramer, Katharina;Nakagami, Hirofumi;Fromm, Hillel;Koncz, Csaba;Zilberstein, Aviah. And the article was included in Plant Science (Shannon, Ireland) in 2018.HPLC of Formula: 444-27-9 This article mentions the following:

The evolutionary conserved family of Selenoproteins performs redox-regulatory functions in bacteria, archaea and eukaryotes. Among them, members of the SELENOPROTEIN O (SELO) subfamily are located in mammalian and yeast mitochondria, but their functions are thus far enigmatic. Screening of T-DNA knockout mutants for resistance to the proline analog thioproline (T4C), identified mutant alleles of the plant SELO homolog in Arabidopsis thaliana. Absence of SELO resulted in a stress-induced transcriptional activation instead of silencing of mitochondrial proline dehydrogenase, and also high elevation of Δ(1)-pyrroline-5-carboxylate dehydrogenase involved in degradation of proline, thereby alleviating T4C inhibition and lessening drought-induced proline accumulation. Unlike its animal homologues, SELO was localized to chloroplasts of plants ectopically expressing SELO-GFP. The protein was co-fractionated with thylakoid membrane complexes, and co-immunoprecipitated with FNR, PGRL1 and STN7, all involved in regulating PSI and downstream electron flow. The selo mutants displayed extended survival under dehydration, accompanied by longer photosynthetic activity, compared with wild-type plants. Enhanced expression of genes encoding ROS scavenging enzymes in the unstressed selo mutant correlated with higher oxidant scavenging capacity and reduced Me viologen damage. The study elucidates SELO as a PSI-related component involved in regulating ROS levels and stress responses. In the experiment, the researchers used many compounds, for example, Thiazolidine-4-carboxylic acid (cas: 444-27-9HPLC of Formula: 444-27-9).

Thiazolidine-2-carboxylic acid, an adduct of cysteamine and glyoxylate, as a substrate for D-amino acid oxidase was written by Fitzpatrick, Paul F.;Massey, Vincent. And the article was included in Journal of Biological Chemistry in 1982.Recommanded Product: 16310-13-7 This article mentions the following:

A mixture of cysteamine and glyoxylate, proposed by G. A. Hamilton, et al. (1979) to form the physiol. substrate of hog kidney D-amino acid oxidase (I), was confirmed to act as a good substrate for the pure enzyme. As proposed by those workers, it was shown that the actual substrate is thiazolidine-2-carboxylic acid (II), formed from cysteamine and glyoxylate with a 2nd-order rate constant of 84 min^-1 M^-1 at 37°, pH 7.5. Steady state kinetic anal. revealed that II was a better substrate at pH 8.5 than at pH 7.5. At both pH values, the catalytic turnover number was similar to that obtained with D-proline. I was rapidly reduced by II to form a reduced enzyme-imino acid complex, as is typical with I substrates. The product of oxidation was shown by NMR to be Δ²-thiazoline-2-carboxylic acid. Racemic II was completely oxidized by I. The directly measured rate of isomerization of L–II to the D-isomer was compared to the rate of oxidation of the L-isomer by I. Their identity over the temperature range 2-30° established that the apparent activity with the L-amino acid can be explained quant. by the rapid, prior isomerization to D–II.

Degradation of 2-Threityl-Thiazolidine-4-Carboxylic Acid and Corresponding Browning Accelerated by Trapping Reaction between Extra-Added Xylose and Released Cysteine during Maillard Reaction was written by Zhai, Yun;Cui, Heping;Zhang, Qiang;Hayat, Khizar;Wu, Xian;Deng, Shibin;Zhang, Xiaoming;Ho, Chi-Tang. And the article was included in Journal of Agricultural and Food Chemistry in 2021.COA of Formula: C4H7NO2S This article mentions the following:

2-Threityl-thiazolidine-4-carboxylic acid (TTCA), a nonvolatile precursor of flavor and color, is considered to be more stable than its isomeric Amadori compound (ARP). The degradation behavior of TTCA favors higher temperatures and pH. In order to adjust and control the thermal degradation of TTCA to improve its food processing adaptability, a TTCA-Xyl thermal reaction model was constructed to explore the effect of extra-added Xyl on the thermal degradation behavior of TTCA. The results confirmed that the extra-added Xyl was involved in the degradation pathway of TTCA and accelerated its depletion, thus promoting the formation of characteristic downstream products of TTCA including some α-dicarbonyl compounds, and consequently accelerating the browning formation. The isotope-labeling technique was further applied to confirm that the added Xyl could trap the Cys released from the decomposition of ARP and formed addnl. TTCA, which could promote the movement of chem. equilibrium and gradually accelerate the degradation rate of TTCA as well as melanoidins formation. The higher pH value could even promote this phenomenon. In the experiment, the researchers used many compounds, for example, Thiazolidine-4-carboxylic acid (cas: 444-27-9COA of Formula: C4H7NO2S).
