摘要: Acylureas and acyclic imides are found to be excellent isosteres for 2-acylamino-1,3,4-thiadiazole in the azaxanthene-based series of glucocorticoid receptor (GR) agonists. The results reported herein show that primary acylureas maintain high affinity selectivity GR while providing improved CYP450 inhibition pharmacokinetic profile over 2-acylamino-1,3,4-thiadiazoles. General methods synthesis a variety from carboxylic acid were utilized described.
