Tanshinone IIA (Tan‑IIA; C19H18O3) is derived from Danshen (the roots of Salvia miltiorrhiza), and has been reported to possess anti‑inflammatory and antioxidant activities. Tan‑IIA can inhibit BxPC‑3 human pancreatic cancer cells in vitro through inducing endoplasmic reticulum stress and apoptosis via mitochondrial pathways. However, the efficacy and molecular mechanisms of Tan‑IIA in human pancreatic cancer have not yet been elucidated.

View Article and Find Full Text PDFTanshinone (Tan)-IIA is a derivative of phenanthrenequinone and the main active ingredient isolated from Salviae miltiorrhizae radix (Danshen). Previous studies have demonstrated that Tan‑IIA increased the protein expressions levels of protein kinase RNA‑like endoplasmic reticulum kinase (PERK), activating transcription factor (ATF) 6, caspase‑12 and CCAAT‑enhancer‑binding protein homologous protein (CHOP), to induce endoplasmic reticulum (ER) stress and apoptosis in human pancreatic cancer BxPC‑3 cells. However, to the best of our knowledge, the effects of Tan‑IIA on pancreatic cancer cells have not been investigated in vivo.
