KX-01 is a dual inhibitor of Src kinase and tubulin polymerization. KX01 promotes the induction of p53, G2/M arrest of proliferating cell populations and subsequent apoptosis via the stimulation of Caspase-3 and PARP cleavage. The drug was developed by Kinex Pharmaceuticals and reached phase II of clinical trials for the treatment of Castration-Resistant Prostate Cancer and Actinic Keratosis. KX-01 demonstrated good in vitro pofile against different cancer cell lines with IC50 in nanomolar range.
