Synthesis, Selective Aldose Reductase Inhibitory Profile and Antihyperglycaemic Potential of Certain Parabanic Acid Derivatives
摘要:
描述了某些对二氨基甲酸衍生物1a-p的合成和醛糖还原酶抑制剖面。此外,研究了这些化合物的抗高血糖潜力。在这个系列中,最活跃的抑制剂是化合物1g、1p和10,它们在浓度为1 x 10−4时分别显示出36.6%、90%和91%的抑制活性。它们的IC50分别为2 x 10−6、7.5 x 10-8和5 x 10-8。化合物10表现出明显的抗高血糖效果。

Ruthenium(II)-catalyzed C–H functionalization of N-arylhydantoins is herein described. The biologically relevant hydantoin (imidazolidinedione) heterocycle functions as a weakly coordinating directing group in a C–H alkenylation reaction. The reaction gave a wide scope of 23 examples with yields up to 94% in the green solvent 2-MeTHF. Functionalization of API nilutamide (antiandrogen) is also reported
