| 描述 | IGF-1R (insulin-like growth factor-1 receptor) plays a key role in transformation, growth and survival of malignant cells, and has been considered as a general and promising target for cancer treatment. Picropodophyllin is a highly specific IGF-1R receptor with IC50 value of 1nM, even does not exhibit inhibition on phosphorylation of IR, a highly homologous receptor of IGF-1R, in cells. Picropodophyllin dose dependently blocked autophosphorylation of IGF-1R induced by IGF-1, as well as its downstream AKT and ERK on phosphorylation level in P6 cells treated with Picropodophyllin at concentration ranging in 0.5-10μM for 1h after 20 hour starvation, and cell apoptosis could be observed after treatment with 0.5μM Picropodophyllin for 6h. Growth inhibition by Picropodophyllin can be observed in a panel of tumor cells from various tumor types with IC50 values≤50nM, including FM 55, SK-MEL-28, SK-MEL-5, C8161, DFB, DFW, AA (melanoma), RD-ES (sarcoma), MCF 7 (breast carcinoma), PC3 (prostate carcinoma), HepG2 (hepatoma), P6 (embryonic mouse fibroblasts) cell lines. Administration of Picropodophyllin (20mg/kg/12h) for 8-14 days blocked growth of IGF-1R-positive tumors and caused complete regression in mice xenograft model of ES-1, BE and PC3[1]. | ||
| 作用机制 | Picropodophyllin may inhibit IGF-1R autophosphorylation at the substrate level, not ATP-competitive.[1] | ||
