AZD-6482 is being developed by AstraZeneca to evaluate its therapeutic effects in the treatment of thrombosis. AZD-6482 is essentially a PI3K-beta inhibitor. It is a PI3Kβ inhibitor with IC50 of 10 nM, 8-, 87- and 109-fold more selective to PI3Kβ than PI3Kδ, PI3Kα and PI3Kγ in cell-free assays. by targeting PI3Kβ, AZD-6482 specifically inhibits thrombosis without interfering with normal haemostasis. Therefore, AZD-6482 is used as an anti-thrombotic drug for the prophylaxis of thrombotic disorders. AZD-6482 was in phase I trials by AstraZeneca for the prevention of thrombosis. However, the study was discontinued.

7-Hydroxystaurosporine (UCN-01) is a protein kinase inhibitor which is under development as an anti-cancer agent in the USA and Japan. Although UCN-01 was originally isolated from the culture broth of Streptomyces sp. as a protein kinase C-selective inhibitor, its ultimate target as an anti-cancer agent remains elusive. As a single agent, UCN-01 exhibits two key biochemical effects, namely accumulation of cells in the G1 phase of the cell cycle and induction of apoptosis. Both these effects may be important for its anti-cancer activity. As a modulator, 7-Hydroxystaurosporine enhances the cytotoxicity of other anti-cancer drugs such as DNA-damaging agents and anti-metabolite drugs through putative abrogation of G2 and/or S phase accumulation induced by these anti-cancer agents. 7-Hydroxystaurosporine had been in phase II clinical trials Life Sciences for the treatment of T-cell lymphoma, malignant melanoma, pancreatic cancer, small cell lung cancer, acute myeloid leukemia, ovarian cancer. However, the research was either discontinued or suspended.
