Asymmetric synthesis of 3(S),17-dihydroxytanshinone
摘要:
The first synthesis of 3(S),17-dihydroxytanshinone was achieved by ultrasound promoted Diels-Alder reaction of the protected 3-hydroxymethyl-4,5-benzofurandione with a vinylcyclohexene derivative. Bioassay showed that the synthetic 3(S), 17-dihydroxytanshinone was active in vitro against HL-60 tumor cell line by MTT method. (C) 2003 Elsevier Ltd. All rights reserved.

Discovery and biological evaluation of tanshinone derivatives as potent dual inhibitors of indoleamine 2, 3-dioxygenase 1 and tryptophan 2, 3-dioxygenase
Indoleamine 2, 3-dioxygenase 1 (IDO1) and tryptophan 2, 3-dioxygenase (TDO), catalyzing the first and rate-limiting step of tryptophan-kynurenine (Trp-Kyn) metabolism pathway, are the appealing targets for cancer immunotherapy. A few dual IDO1/TDO inhibitors are reported in literature. However, small-molecule IDO1 and TDO inhibitors are not yet available for clinical use. Here, we report synthetic
