Cat.No. 5424 - Deltarasin | C40H37N5O.3HCl | CAS No. 1440898-82-7
Description: High affinity PDEδ-KRAS interaction inhibitor
Chemical Name: 2-[4-[(2S)-2-(2-Phenyl-1H-benzimidazol-1-yl)-2-(4-piperidinyl)ethoxy]phenyl]-1-(phenylmethyl)-1H-benzimidazole trihydrochloride
Purity: ≥99% (HPLC)

Biological Activity

High affinity PDEδ-KRAS interaction inhibitor (Kd = 41 nM); binds to PDEδ. Reduces proliferation and induces cell death of KRAS-dependent Panc-Tu-1 and Capan-1 pancreatic cancer cells. Attenuates tumor growth of Panc-Tu-1 xenografts in mice.
