CAS#: 118525-40-9

Description: Icaritin is an oral traditional Chinese medicine, derived from barrenwort, which targets the estrogen receptor α36. IC50 values for Icaritin are 8,13 and 18 μM for K562, CML-CP and CML-BC cells respectively. Icaritin inhibits the invasion and epithelial-to-mesenchymal transition of glioblastoma cells by targeting EMMPRIN via PTEN/AKt/HIF-1α signalling. Icaritin suppresses hepatocellular carcinoma initiation and malignant growth through the IL-6/Jak2/Stat3 pathway. Icaritin activates JNK-dependent mPTP necrosis pathway in colorectal cancer cells.
