as PKA,. PKC, PKG, calmodulin kinase,.. that we tested (K252a, K252c, and G6976) were toxic for the. K252a inhibits the phosphorylation of pRb without changing the levels of G1 cyclins and Cdk2 protein in human hepatoma cells. File Format: PDFAdobe Acrobat - View as HTML The structurally related indolocarbazole alkaloids (+)-K252a1,2 (1) and (2) have attracted considerable attention due to the unique.
