The efficacy of docetaxel/prednisone with or without enzastaurin, an inhibitor of the beta isoform of protein kinase C with therapeutic activity against prostate cancer, in patients with castration-resistant metastatic prostate cancer has been explored.
Follicular lymphoma cells are characterized not only by genetic alterations involving Bcl-2, Bcl-6 OR C-mYc but also by alterations in B-cell receptor signaling pathways.
PFS-6 was evaluated in newly diagnosed gliobstoma patients who were MGMT- promoter-hypermethylation-free and posturgically treated with enzastaurin plus radiation.
The combination of enzastaurin and bevacizumab, which showed synergistic antitumor activity in preclinical studies, was evaluated for safety and efficacy.
Enzastaurin with 5-fluorouracil/leucovorin plus bevacizumab was evaluated as maintance therapy for MCRC, since the combination of enzastaurin and bevacizumab was well-tolerated and demonstrated synergistic antitumor effects in phse 1 studies.
Enzastaurin is an ATP-competitive, selective oral inhibitor of protein kinase Cβ with IC50 value of 6 nM .
Protein kinase C (PKC) is a family of serine-threonine protein kinases that have been proved to play critical roles in the formation and progression of tumor cells. The PKCβ is especially found to contribute to the growth and proliferation of tumors such as diffuse large B-cell lymphoma, multiple myeloma and chronic lymphoid leukemia. The selective PKCβ inhibitor enzastaurin was found to have antiangiogenic activity in tumor model as well as suppress tumor proliferation and induce apoptosis. Besides that, enzastaurin showed the inhibitory effects on phosphorylation of ribosomal protein S6, GSK3β and AKT which are in pathways influenced by PKC. Due to these, enzastaurin was developed as a therapy for cancer [1 and 2].
Enzastaurin at low concentration suppressed cell proliferation of various tumor cells including colon carcinoma (HCT-116), glioblastoma (U87MG), non–small cell lung cancer (A549), melanoma (M14), ovarian cancer (OVCAR-3), breast cancer (MCF-7), leukemia (K562), prostate cancer (PC-3), renal cancer (CAKI-1) and central nervous system cancer (U251). Enzastaurin induced apoptosis of tumor cells at low concentration in a range of 1 to 4 μM and the apoptosis was proved to be caspase-independent. In addition, enzastaurin suppressed the phosphorylation ofGSK3βSer9, ribosomal protein S6Ser240/244 and AKTThr308 time-dependently in tumor cells and affected these pathways [1 and 3].
In mice models, oral administration of enzastaurin at a dose of 75 mg/kg resulted in significant proliferation inhibition of U87MG glioblastoma or HCT116 coloncarcinoma xenografts. In mice bearing human walden strommacro globulinemia xenografts, administration of enzastaurin at dose of 80 mg/kg significantly reduced tumor growth of WM and increased survival [1 and 2].
