  Discovery of a nonpeptidic small molecule antagonist of the human platelet thrombin receptor (PAR-1)

  摘要：

  The synthesis and biological evaluation of a series of nonpeptidic small molecule antagonists of the human platelet thrombin receptor (PAR-1) are described. Optimization of the 5-amino-3-arylisoxazole lead resulted in an approximate 100-fold increase in potency. The most potent of these compounds (54) inhibits platelet activation with IC50S of 90 nM against the thrombin receptor agonist peptide (TRAP) and 510 nM against thrombin as the agonist. Further, antagonist 54 fully blocks platelet aggregation stimulated by 1 nM thrombin for 10 min. (C) 2002 Published by Elsevier Science Ltd.

  The Rh(III)-catalyzed [4 + 2] annulation of 3-aryl-5-isoxazolones with maleimides or maleic ester has been developed, which gives synthetically important 3,4-dihydroisoquinoline derivatives in good to excellent yields. This facile protocol can tolerate a variety of functional groups, and CO2 was produced as the predominant byproduct. Notably, a C–C bond and a C–N bond were formed simultaneously. This

  A palladium catalyzed insert reaction of isocyanides to 3-arylisoxazol-5(4H)-ones for the construction of 4-aminomethylidene isoxazolone derivates is reported. In this transformation, only the C–H bond of the methylene group was involved while the remaining ring structure was retained. In general, this work provided a new protocol for the synthesis of 4-aminomethylidene isoxazolones.

  An efficient I2-mediated sulfonylation at 4-position of isoxazoles has been developed by employing sodium sulfinate and 3-substituted isoxazol-5(4H)-ones. This metal-free, one-pot strategy provides various sulfonyl isoxazoles under mild reaction conditions. The final product exists in the form of stable organic sodium salt, which can be purified by column chromatography under air.
