Hedgehog signal channel, a channel that plays a role in the occurrence and development of a variety of cancers. We introduce the composition and mechanism of Hedgehog signal channel, and the anti-tumor mechanism. A series of derivatives were designed and synthesized with the Hedgehog signal channel inhibitor Itraconazole in clinical phase II as the precursor. Compared with the other inhibitors, Itraconazole has a weaker inhibitory effect on Hedgehog, and there are few studies on improving the anti proliferation ability of Itraconazole on cells. Therefore, using Itraconazole as the lead, we obtained a series of derivatives that can effectively inhibit Hedgehog channels. Compared with Itraconazole, compounds 12g and 12n had stronger inhibitory effects in A549 cells.
