Description: PRLX 93936 is a structural analogue of erastin with potential antineoplastic activity. Erastin analogue PRLX 93936 appears to inhibit mitochondrial outer membrane protein VDACs (voltage-dependent anion channels) 2 and 3, resulting in an oxidative, non-apoptotic cell death. Erastin analogue PRLX 93936 exhibits greater lethality in cell lines harboring mutations in the GTPase protein oncogenes HRAS and KRAS or the serine-threonine protein kinase oncogene BRAF than in non-tumorigenic cell lines. VDACs 2 and 3 are up-regulated in a wide variety of tumor cell lines.

Additional Information

PRLX 93936 is a product of extensive SAR work originating from a small molecule identified in a synthetic lethal screen against isogenic cell lines engineered to differentially express several genes including activated RasV12. Preclinical pharmacodynamic and toxicological studies, suggest that PRLX 93936 has great therapeutic potential and therefore, Prolexys initiated a Phase I clinical trial in August, 2007.
