Biological Activity

Description

Pemrametostat (GSK3326595, EPZ015938) is an orally active, potent and selective inhibitor of protein arginine methyltransferase 5 (PRMT5) and potently inhibits tumor growth in vitro and in vivo in animal models.

Targets

PRMT5 ^[1]

In vitro

Both GSK3326595 and Santacruzamate A treatments rescue the ZEB2-mediated E-cadherin promoter suppression in SW480-ZEB2 cells, confirming that the ZEB2-mediated repression of E-cadherin in CRC cells is facilitated by PRMT5 and HDAC2.^[2]

In vivo

GSK3326595 reduces liver metastasis of CRC cells and completely inhibits the distant metastasis of SW620 cells in nude mice.^[2]

Protocol (from reference)

Cell Assay:^{^[2]}	Cell lines SW480 cells Concentrations 100, 250, 500 nM Incubation Time 48 h Method SW480+Vector and SW480+ZEB2 cells express plasmid pGL3-E-cadherin promoter-Luc. InPRMT5 (GSK3326595) and inHDAC2 (Santacruzamate A) were added to the cell medium, and luciferase activity was assayed, 48 h later, luciferase activity was assayed and normalized to Renilla. (E) SW620 cells express plasmid pGL3-E-cadherin promoter-Luc. InPRMT5 (GSK3326595) and inHDAC2 (Santacruzamate A) were added to the medium, and luciferase activity was assayed, 48 h later, luciferase activity was assayed and normalized to Renilla.
