Design and Synthesis of Protein Kinase B-Inhibitors

Protein kinase B (PKB/Akt) is a downstream protein in the phosphoinositol 3-kinase (PI3K) pathway. Its overexpression is observed in ovarian, breast, prostate, and pancreatic cancer in which the PI3K pathway is disregulated. This makes PKB an attractive molecular target for cancer therapy. Using Moloc®, we designed a number of potential inhibitors and propose their synthesis.
