MedKoo CAT#: 564061

CAS#: 35954-65-5 (6S-isomer)

Description: FR054 is an inhibitor of the Hexosamine Biosynthetic Pathway (HBP) enzyme PGM3, with a remarkable anti-breast cancer effect. FR054 induces in different breast cancer cells a dramatic decrease in cell proliferation and survival. In particular, in a model of Triple Negative Breast Cancer (TNBC) cells, MDA-MB-231, these effects are correlated to FR054-dependent reduction of both N- and O-glycosylation level that cause also a strong reduction of cancer cell adhesion and migration. . Note: The correct structure for FR054 is CAS#35954-65-5 which is the 6S-isomer. Some vendors are selling wrong structure for FAR054 (the incorrect structure has CAS#10378-06-0, which is the 6R-isomer)
