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

MedKoo CAT#: 406512

CAS#: 129414-88-6

Description: KRIBB3 is novel and potent microtubule inhibitor with potential anticancer activity. KRIBB3 has anti-migratory and anti-invasive activities in MDA-MB-231 cells. KRIBB3 inhibits tumor cell migration and invasion by blocking protein kinase C-dependent phosphorylation of Hsp27 through its direct binding to Hsp27.
