Discovery of orally active butyrolactam 11β-HSD1 inhibitors
摘要:
A series of metabolically stable butyrolactam 11 beta-HSD1 inhibitors have been synthesized and biologically evaluated. These compounds exhibit excellent HSD1 potency and HSD2 selectivity, pharmacokinetic, and pharmacodynamic profiles. (c) 2006 Elsevier Ltd. All rights reserved.
A Highly Efficient Synthesis of Potent and Selective Butyrolactam Inhibitors of 11β-Hsd1
摘要:
A convergent synthesis of structurally novel butyrolactam 11 beta-HSD1 inhibitors is described. The approach features an efficient Ireland-Claisen reaction to construct a highly substituted aldehyde building block which is converted to a lactam via a tandem reductive amination/cyclization sequence. The generality of the synthetic sequence is demonstrated during the preparation of two additional potent 11 beta-HSD1 inhibitors.
