Antischistosomal activity of N,N′-arylurea analogs against Schistosoma japonicum
摘要:
Although the antischistosomal activities of N,N'-arylurea analogs were reported, systematic structure-activity relationships have not been conducted. In this Letter, we reported the design, synthesis and evaluation of 45 N,N'-arylurea analogs. Among these prepared compounds, 13 compounds were urea linker modified and 32 were N,N'-arylurea derivatives. The activity evaluation revealed 12 analogs exhibited IC50 values lower than 22.6 mu M, and 7 of them had IC50 less than 10 mu M against the juvenile Schistosoma japonicum in vitro. Their worm killing potency was even higher against adult worm. Unfortunately, low to moderate worm burden reduction of 0-33.4% was recorded after administration of a single oral dose of 200 mg/kg or 400 mg/kg to mice harboring S. japonicum.

Abstract Thioureas and their derivatives are organosulfur compounds having applications in numerous fields such as organic synthesis and pharmaceutical industries. Symmetric thiourea derivatives were synthesized by the reaction of various anilines with CS2. The synthesized compounds were characterized using the UV-visible and nuclear magnetic resonance (NMR) spectroscopic techniques. The compounds
The present invention provides novel [3-substituted-2-(substituted imino)-4-oxo-5-thiazolidinylidene]acetic acids, and novel pharmaceutical compositions and methods of use thereof. The novel acids of the invention are leukotriene antagonists having activity useful for treating asthma, allergies, cardiovascular diseases, migraines, and inflammation.

A highly efficient procedure for the synthesis of symmetrical thioureas by means of simple condensation of primary amines and carbon disulfide in 1-butyl-3-methylimidazolium chloride [BMIM][Cl] as a cheap and commercially available ionic liquid is presented. This procedure works for aromatic and aliphatic primary amines and give high to excellent yields of symmetrical thioureas without need for any catalyst or tedious work-up.
