Deltarasin is an inhibitior of KRAS-PDEδ which has been shown to impair oncogenic signalling. | [Biological Activity]
the kras oncogene product is considered a major target in anticancer drug discovery. interfering with binding of mammalian pdeδ to kras by means of small molecules provides a novel opportunity to suppress oncogenic ras signalling by altering its localization to endomembranes. deltarasin is an inhibitor of the kras-pdeδ interaction to impair oncogenic kras signalling. | [in vitro]
within a minute, 5 mm of deltarasin completely inhibited pdeδ-kras interaction and released the insolubilized mcitrine-rheb/kras6q to the endomembrane system. this showed that deltarasin interfered with the binding of kras to pdeδ in cells and thereby inhibited its solubilization [1]. | [in vivo]
a clear dose-dependent reduction in panc-tu-i tumour growth rate could be observed in deltarasin treated mice with respect to the vehicle-injected controls, where the growth of tumours in mice that were treated with 10mg kg/1 bid deltarasin was almost completely blocked [1]. | [storage]
