    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 406621

CAS#: 1346528-06-0 (free base)

Description: ML241 is a potent and selective inhibitors of p97 ATPase. ML241 inhibit p97 ATPase with IC(50) values of 100 nM. ML241 inhibits degradation of a p97-dependent but not a p97-independent proteasome substrate in a dual-reporter cell line. ML241 may be a novel agent for the chemotherapy of cancer, and provide a rationale for developing pathway-specific p97 inhibitors.
