Analogues of Acifran: Agonists of the High and Low Affinity Niacin Receptors, GPR109a and GPR109b
摘要:
Recently identified GPCRs, GPR109a and GPR109b, the high and low affinity receptors for niacin, may represent good targets for the development of HDL elevating drugs for the treatment of atherosclerosis. Acifran, an agonist of both receptors, has been tested in human subjects, yet until recently very few analogs had been reported. We describe a series of acifran analogs prepared using newly developed synthetic pathways and evaluated as agonists for GPR109a and GPR109b, resulting in identification of compounds with improved activity at these receptors.

dicyclohexylphenylphosphine provides a useful catalyst system for the addition of boronicacids to 1,2-diketones and 1,2-ketoesters. The best yields were obtained when the transformation was performed in DME/H2O at 80 °C with 4 equiv of the boronicacid. The results discussed herein extend the scope of the addition of arylboronic acids to highly activated diketones and ketoesters. The products of the reaction
在二环己基苯基膦的存在下,金属络合物Rh(acac)(CO)2提供了有用的催化剂体系,用于将硼酸加成到1,2-二酮和1,2-酮酸酯中。当在80°C的DME / H 2 O中加入4当量的硼酸进行转化时,可获得最佳的收率。本文讨论的结果扩展了将芳基硼酸添加到高度活化的二酮和酮酸酯的范围。该反应的产物可用于合成在酯或酮之后含氧的天然产物。
