摘要
Vismodegib is an oral and high selective hedgehog (Hh) inhibitor used for the treatment of basal cell carcinoma (BCC). In this work, analogs of Vismodegib with deuterium-for-hydrogen replacement at certain metabolically active sites were prepared and found to have a better pharmacokinetic properties in mice. In particular, deuterated compound SKLB-C2211 obviously altered the blood circulation behavior compared to its prototype, which was demonstrated by significantly prolonged blood circulation half-life time (t1/2) and increased AUC0→∞. These results suggested SKLB-C2211 had the potential to be a long-acting inhibitor against Hh signaling pathway, and laid the foundation for the further research of its druggability.
