Background:

PF-04929113 is an inhibitor of Hsp90 [1].

PF-04929113 is a water-soluble and oral pre-PF-04928473, which can be rapidly absorbed and converted into PF-04928473 after oral administration. In BT-474 xenograft mice, PF-04928473 induced the degradation of HER2 client protein. No obvious toxicity was observed when the dose reached 150mg/kg. PF-04928473 at 100mg/kg resulted in complete tumor growth inhibition and local tumor regression in some mice. In H1650 xenograft mice, PF-04928473 also showed significant anti-tumor activity. In addition, as an inhibitor of Hsp90, PF-04928473 inhibits p-ERK and p-Akt in vivo, reduces CD31+ cells and MVD, and has an effect on angiogenesis [1,2].
