Periplocin 是一类从香加皮中分离出的强心类固醇。Periplocin 可促进肿瘤细胞凋亡并抑制肿瘤生长。Periplocin 通过激活 Na/K-ATPase 介导的 Src/ERK 和 PI3K/Akt 途径而具有促进伤口愈合的潜力。
生物活性 | Periplocin is a cardiotonic steroid isolated from root-barkPeriploca sepiumBunge. Periplocin promotes tumor cellapoptosisand inhibits tumor growth. Periplocin has the potential to facilitate wound healing through the activation of Src/ERK and PI3K/Akt pathways mediated by Na/K-ATPase[1][2]. |

体外研究 (In Vitro) | Periplocin (5-20 μM; 48 hours; L929 cells) treatment shows increased proliferation up to 131% at 20 μM[1]. Periplocin (5-20 μM; 30-120 minutes; L929 cells) increases phosphorylation of Src, ERK, PI3K and Akt at active sites in a dosedependent and time-dependent manner.
Periplocin (5-20 μM; 48 hours) significantly promotes migration of fibroblast cell[1]. Periplocin (5-20 μM; 48 hours) increases collagen production in L929 fibroblast[1]. Periplocin induces Na/KATPase mediates the activation of Src/ERK and PI3K/Akt pathways[1].
