TAK-441 is a novel, orally bioavailable, potent and selective Hedgehog (Hh) signaling pathwayinhibitor with acceptable solubility and pharmacokinetic properties. Itbinds to Smo and is being developed for the treatment of cancer. Hedgehog (Hh) signaling is a highly conserved intercellular and intracellular communication mechanism that governs organogenesis and is dysregulated in cancers of numerous tissues, including prostate. TAK-441 suppressed transcription factor Gli1 mRNA expression in tumor-associated stromal tissue and inhibited tumor growth (treatment/control ratio, 3%) in a mouse medulloblastoma allograft model owing to the improved PK profile based on increased solubility. TAK-441is currently in clinical trials for the treatment of advanced solid tumors.
| ln Vitro |
TAK-441 (compound 11d) (0.03–1000 nM, 48 h) exhibits good solubility and strong activity in the Gli-luc reporter, with an IC50 value of 4.4 nM[1]. With IC50 values of 0.0457 and 0.113 mg/ml in the tumor and skin, respectively, TAK-441 (0.03–1000 nM, 48 h) inhibits Gli1 mRNA[1]. The androgen withdrawal-induced Shh up-regulation is not affected by TAK-441 (0.5-500 nM, 48-72 h). However, by interfering with paracrine Hh signaling with the tumor stroma, TAK-441 (0.5-500 nM, 48-72 h) causes LNCaP xenografts to progress more slowly, resistant to castration[3].

| ln Vivo |
In BALB/c-nu/nu mice, TAK-441 (compound 11d) (oral; 10 mg/kg, 100 mg/kg) exhibits a favorable exposure and good oral absorption[1]. Strong anticancer efficacy is exhibited by TAK-441 (oral, 1 and 25 mg /kg, QD for 14 days), which can produce dose-dependent plasma and tumor concentrations by increasing TAK-441's solubility in Ptc1+/-p53-/-mice receiving medulloblastoma allografts[1]. After oral dosing, TAK-441 (iv, 1 mg/kg; po, 10 mg/kg) can produce enough exposure in rats and dogs[1]. In xenografted mice, TAK-441 (oral; 1, 10, and 25 mg/kg) has dose-dependent anticancer efficacy; the IC50 value for the suppression of tumor development is 0.075 mg/ml[1].
