BIIB-021 Usage And Synthesis

Description

BIIB021 is a potent HSP90 inhibitor (IC50 = 30 nM HER-2 degradation).1 It inhibited the proliferation of MCF7 and BT474 breast cancer cell lines (IC50 = 100 nM for each).? BIIB021 has shown efficacy as a therapeutic in multiple cancer models.2-5

Uses

BIIB 021 an orally available, fully synthetic small-molecule inhibitor of the heat shock protein Hsp90. Studies show that BIIB 021 adminisitration led to degradation of Hsp90 client proteins measured in tumor tissue and resulted in the inhibition of tumor growth in several human tumor xenograft models.

Definition

ChEBI: A member of the class of 2-aminopurines that is 2-aminopurine which is substituted by a chlorine at position 6 and by a (4-methoxy-3,5-dimethylpyridin-2-yl)methyl group at position 9.
