Chemical structure
| Animal experiment [1]: | |
Animal models | Rats and dogs |
Dosage form | 1 mg/kg and 0.5 mg/kg, Oral dosing |
Application | In rats and dogs, PF-04449913 had high clearance in rat and low clearance in dog with CL of 31 and 3.9 mL/min/kg, respectively. The oral bioavailabilities of PF-04449913 in rat and dog were 33 and 68%, respectively. PF-04449913 had moderate volume distribution of 4.8 and 4.3 L/kg and t1/2 of 1.4 and 2.9 h, respectively. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
| Clinical Trial [2]: | |
Disease models | Patients with advanced solid tumors |
Dosage form | 80 mg-640 mg, orally administered once daily, continuous 28-day |
Application | In patients with advanced solid tumors, the first-cycle dose-limiting toxicity (DLT) rate at the 640 mg dose level was 33.3%, and the maximum tolerated dose (MTD) of PF-04449913 was estimated to be 320mg once daily. PF-04449913 was generally well tolerated at doses of 80 to 320 mg once daily. PF-04449913 modulated hedgehog signaling at the dose levels tested and downregulated GLI1 expression in the skin of patients by >80%. |

PF-04449913 is an orally bioavailable inhibitor of smoothened with IC50 value of 5nM [1].
In the Hedgehog (Hh) signaling pathway, the combination of Hh ligands and their receptor Patched leads to the activation of smoothened and subsequently activation of three transcription factors Gli1, Gli2 and Gli3. It then leads to the proliferation of cells. As an antagonist of smoothened, PF-04449913 is developed for treatment of cancer [1].
PF-04449913 is found not to inhibit cytochrome P450 and is negative in Ames and micronucleus assays suggesting it as a safe drug. In the preclinical studies, PF-04449913 shows a half-life of 30 h and an oral bioavailability of 55% in humans. It also has low plasma clearance of 1.03 mL/min/kg and moderate volume of distribution (2.7 L/kg) [1].
