A new sulfenylation reagent, 3-phenylsulfenyl-2-(N- cyanoimino)thiazolidine, and its optically active version

We have developed a new sulfenylation reagent, 3-phenylsulfenyl-2-(N- cyanoimino)thiazolidine 3, that is readily available and stable upon storage. Compound 3 easily reacts with amines or thiols to give the corresponding sulfenamides or asymmetrical disulfides in excellent yields. It was also found that the alpha-sulfenylation reaction of carbonyl compounds with 3 proceeds smoothly. Furthermore, optically active 4-diphenylmethyl derivative 4 was synthesized as an asymmetric sulfenylation reagent, which realized 96% e.e. upon alpha-sulfenylation of a cyclic beta-keto ester.

Synthesis and characterization of new Thiazolidinones which are used to decrease blood glucose level

This study is concerned with the synthesis and characterization derivatives of Thiaszolidinones 3a-e. These compounds were synthesized by reacting of thioglycolic acid with the appropriate Schiff base 2a-e, in the presence of dry benzene in moderate yields (69-73%). The structures of Thiaszolidinone were established on the basis of the spectral data like FT-IR, 1H-NMR, 13C-NMR, Gcosy and Mass.

Oxazolidine-2-thiones and thiazolidine-2-thiones as nucleophiles in intermolecular michael additions

Conjugate addition of thiazolidinethiones and oxazolidinethiones to N-crotonylthiazolidinethiones and -oxazolidinethiones was observed in the presence of excess triethylamine in dichloromethane. The addition takes place by the nitrogen of the heterocycle with high diastereoselectivity. It was observed that the stereoselective addition occurs on the anti-s-cis conformation of the N-enoyl sulfur-containing heterocycle.

Sulfur containing acridine derivatives in preclinical studies with cancer cell lines

Background: The possible use of acridines as anticancer agents was first considered in the 1920?s. Since then, a large number of acridine drugs have been tested as antitumour agents, including compounds containing sulphur on the acridine chromophore. In this review, we will discuss recent studies which have investigated the anticancer activity of this class of acridine derivatives. Methods: We present the results both of our own decade-long research and also of existing research literature into the anticancer activity of acridine derivatives containing sulphur. The evidence of specific tumor-cell killing properties displayed by these compounds suggest the potential of using such molecules as anticancer therapeutics. Results: During the last decade, a number of acridine analogs have been developed by modifying the position and the nature of the substituent on the acridine core. In this paper, we published results on the anticancer activity of acridine derivatives containing sulfur (acridine thioureas, acridine thiazolidine/thiazoidinone, and acridine thiosemicarbazones/ thiosemicarbazides). In cancer chemotherapy, the mechanism of the drugs is complex, although the study of the anticancer activity of acridines has yielded exciting results. Conclusion: In this review we have summarized recent literature on the anticancer activity of acridine derivatives containing sulfur. A considerable amount of published data suggests that these compounds exhibit promising anticancer activity against selected cancer cell lines. The obtained results can be helpful in the development of new pharmaceutical agents.

Physiological basis of the pathogenesis of alcohol-induced skeletal muscle injury

Alcohol-induced muscle damage (AIMD) is an umbrella term that includes all forms of alcoholic myopathy developing in acute or chronic alcohol intoxication. The most common form of destruction of skeletal muscles in alcoholism is chronic alcoholic myopathy, which develops independently of other alcohol-induced disorders, such as polyneuropathy, the malabsorption syndrome, and liver damage, but may be combined with them. The atrophy of muscle fibers underlies skeletal muscle destruction in chronic AIMD. Type II muscle fibers are affected to a greater degree than type I muscle fibers. To date, the pathogenesis of chronic alcoholic myopathy has been studied insufficiently. The imbalance between protein synthesis and proteolysis, as well as increased apoptosis rate, is discussed.
