Pim kinases (Provirus Integration site for Moloney murine leukemia virus) are a family of serine/threonine kinases that regulate cell survival. This family of kinases is composed of three different isoforms (Pim-1, Pim-2, and Pim-3). The simultaneous inhibition of Pim-1, Pim-2, and Pim-3 kinases is emerging as a promising strategy for anticancer drug development. CX-6258 is a potent, selective, and orally efficacious pan-Pim kinases inhibitor.
In vitro: CX-6258 exhibited in vitro synergy with chemotherapeutics. The antiproliferative activity of CX-6258 was examined against a panel of cell lines derived from human solid tumors and hematological malignancies. CX-6258 demonstrated robust antiproliferative potencies against all cell lines tested .
In vivo: CX-6258 was evaluated in two human tumor xenograft growth efficacy models, acute myeloid leukemia MV-4-11, and prostate adenocarcinoma PC3. The drug exhibited dose dependent efficacy, with a 50 mg/kg dose producing 45% tumor growth inhibition (TGI) and a 100 mg/kg dose producing 75% TGI. In addition, CX-6258 displayed significant efficacy in vivo in two xenograft models representing the diseases where Pim kinases had been shown to play an important role .
