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

PF-04929113 is a water soluble and orally bioavailable prodrug of PF-04928473. It is rapidly absorbed and converted into PF-04928473 after oral administration. In mice bearing BT-474 tumor xenografts, treatment of PF-04928473 causes the degradation of the HER2 client protein. And no obvious toxicity is observed when the dose of PF-04928473 is up to 150mg/kg. Treatment of 100mg/kg PF-04928473 results in complete tumor growth inhibition and in some mice partial tumor regressions. PF-04928473 also shows significant antitumor activity in mice with H1650 xenografts. In addition, as an inhibitor of Hsp90, PF-04928473 is reported to inhibit p-ERK and p-Akt, decrease CD31+ cells and MVD as well as a have an effect on angiogenesis in vivo [1, 2].
