Go6976 have no effect on the kinase activity of the Ca(2+)-independent PKC subtypes delta, epsilon, and zeta. [1] Beside WT JAK2, Go6976 also inhibits the mutant forms (JAK2 V617F and TEL-JAK2) found in haematological malignancies, and has activity against mutant forms of FLT3. In AML cells, Go6976 reduces the survival to 55% of control in FLT3-ITD cases and to 69% in FLT3-WT samples.[2] Go 6976 potently inhibits HIV-1 induction by Bryostatin 1, tumor necrosis factor alpha, and interleukin 6.
