Isoquinoline–pyridine-based protein kinase B/Akt antagonists: SAR and in vivo antitumor activity
摘要:
The structure-activity relationships of a series of isoquinoline-pyridine-based protein kinase B/Akt antagonists have been investigated in an effort to improve the major short-comings of the lead compound 3, including poor pharmacokinetic profiles in several species (e.g., mouse iv t(1/2) = 0.3 h, po F= 0%). Chlorination at C-1 position of the isoquinoline improved its pharmacokinetic property in mice (iv t(1/2) = 5.0 h, po F = 51%) but resulted in > 500-fold drop in potency. In a mouse MiaPaCa-2 xenograft model, an amino analog 10y significantly slowed the tumor growth, however was accompanied by toxicity. (c) 2006 Elsevier Ltd. All rights reserved.
