Descriptions:
Tanshinone Ⅱ-A is a derivative of phenanthrenequinone isolated from Salvia miltiorrhiza BUNGE, a traditional herbal medicine that is known to induce anti-inflammatory, anti-oxidative and cytotoxic activity; tanshione Ⅱ-A induces HL60 and K562 cellular apoptosis that may be associated with the selective members of caspase family[1]
Acetyltanshinone IIA (ATA), a novel anti-cancer agent, preferentially inhibits cell growth of oestrogen receptor positive (ER+) breast cancer cells and that it is more potent than the commonly used anti-breast cancer agent, tamoxifen; ATA also reduces the mRNA levels of the ERα encoding gene, ESR1, and reduces the transcription of an ER-responsive gene, GREB1.[2]
Tanshinone IIA may inhibit LPS-induced IκBα degradation and NF-κB activation via suppression of the NIK–IKK pathway as well as the MAPKs (p38, ERK1/2, and JNK) pathway in RAW 264.7 cells and these properties may provide a potential mechanism that explains the anti-inflammatory activity of tanshinone IIA.[3]
Tanshinone IIA reduces apoptosis induced by hydrogen peroxide in the human endothelium-derived EA.hy926 cells.[4]
Tanshinone IIA has significant growth inhibition effects on THP-1 cells by induction of apoptosis, and that tanshinone IIA-induced apoptosis on THP-1 cells is mainly related to the disruption of Deltapsim and activation of caspase-3 as well as down-regulation of anti-apoptotic protein Bcl-2, survivin and up-regulation of pro-apoptotic protein Bax, suggests Tanshinone IIA may serve as a potential anti-leukemia reagent.[5]
