alpha-Amino aldehyde 4, which is readily derived from L-cysteine through cyclization and elaboration of the carboxy group, was subjected to the Strecker reaction, which, via sodium bisulfite adduct 16, afforded alpha-amino nitrile 5 with high diastereose-lectivity (syn/anti = 11:1) and in high yield. Amide 6, derived from 5, was converted to thiolactone 8, a key intermediate in the synthesis of (+)-biotin (1), by a novel S,N-carbonyl migration and cyclization reaction. The Fukuyama coupling reaction of 8 with the zinc reagent 21, which has an ester group, in the presence of a heterogeneous Pd/ C catalyst allowed the efficient installation of the 4-carboxybutyl chain to provide 9. Compound 9 was hydrogenated and the protecting groups removed to furnish 1 in 10 steps and in 34 % overall yield from L-cysteine.

The compound – Thiazolidin-2-one played an important role in people’s production and life., Electric Literature of 2682-49-7

New tetrahydro-1H-pyrazolo[3,4-b]quinoline derivatives were designed, synthesized and characterized as dual anticholinestrase and cyclooxygenase-2 inhibitors. The in vitro and in vivo anti-cholinesterase evaluation exhibited promising activities with lower hepatotoxicity for many candidates compared to tacrine as a reference. Furthermore, their anti-inflammatory activity using in vitro (COX-1/COX-2) inhibitory assay demonstrated superior activity to celecoxib with higher selectivity indices for some compounds. In addition, some candidates showed extended anti-inflammatory activity by inhibiting COX-2 protein induction. Besides, in silico docking experiments of the active compounds against hAChE rationalized the observed in vitro AChE inhibitory activity. In conclusion, this work provides an extension of the chemical space of tetrahydro-1H-pyrazolo[3,4-b]quinoline chemotype for the anticholinestrase and anti-inflammatory activity. This would aid to minimize the possible neuroinflammation linked to the pathogenesis of Alzheimer’s disease.

In a patent, 2682-49-7, name is Thiazolidin-2-one, introducing its new discovery. Application of 2682-49-7

In this study, thiourea derivatives [1-4] were synthesized by using 2-amino-4-substituted pyridine compounds and these compounds have been used as the starting materials for synthesis of 2-imino-1,3-thiazolidin-4-one ring [5, 6]. Two different procedures for 4-thiazolidinone ring closure and synthesis method were optimized. The synthesized compounds were identified by the help of elemental analysis, IR, 1H-NMR, 13C-NMR and mass spectral data while the purities of them were proved with TLC. Synthesized compounds were evaluated for their antiviral and anticancer activity. Antiviral activity against Murine norovirus, Yellow fever, Enterovirus and Chikungunya strains of the test compounds were investigated and EC50 values of these compounds were determined higher than 0,3 muM. Cytotoxicity of test compounds was examined on NIH3T3 cell line. When the anticancer activity of test compounds was examined against PC-3, A549, HeLa, HT-29, MCF-7, SJSA1 and K562 cell lines, the percent proliferation values of these compounds were observed over 61% for all cell lines.

Healthcare careers for chemists are once again largely based in laboratories, although increasingly there is opportunity to work at the point of care, helping with patient investigation. In a patent, 185137-29-5, name is (S)-4-Phenylthiazolidine-2-thione, introducing its new discovery. Application of 185137-29-5

A series of simple structural 1,3-thiazolidine-2-thione derivatives with various substituents on the S-, N-, 4-, and 5-positions was synthesized with high yields from various vicinal amino alcohols via two steps and screened for their antifungal activity. Bioassay results reveal that some thiazolidine-2-thione derivatives show strong antifungal activities against P. capsici, G. zeae, S. sclerotiorum, A. alternata, B. cinerea, or R. solani. The SAR analysis indicates that N-acyl substituted and 4-alkyl substituents can enhance the antifungal activity. Notably, 4-isopropyl-N-propionylthiazoldine-2-thione shows excellent activity against B. cinerea and G. zeae with IC50 values at 3.7 g/mL and 6.5 g/mL, respectively, and 4-isobutyl-N-propionylthiazoldine-2-thione shows remarkable fungicidal activity against R. solani, S. sclerotiorum, and G. zeae with IC50 values at 1.0 g/mL, 12.1 g/mL, and 11.0 g/mL, respectively.
