Total Synthesis of Tanshinone I

Journal of Natural Products, 2017
A novel total synthesis of tanshinone I (1) via the intermediate 3-hydroxy-8-methyl-1,4-phenanthrenedione (8) is described. The low overall yields and the use of expensive reagents in the synthesis process were minimized by the use of the Diels-Alder reaction to directly construct the 1,4-phenanthrenedione scaffold, providing tanshinone I (1) in only ...

Tanshinone IIA in Acute Promyelocytic Leukemia

The American Journal of the Medical Sciences, 2012
The prognosis of acute promyelocytic leukemia (APL) has been significantly improved by the use of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO). However, the utility of these drugs is limited by resistance to ATRA and the side effects of ATO.

Isolation and Bioactivity of New Tanshinones

Journal of Natural Products, 1987
Two new diterpenoids, designated neocryptotanshinone and isotanshinone IIB, have been isolated from "Tan-Shen," the root of Salvia miltiorrhiza, together with a known compound, danshexinkun A. Their structures are established by spectral and physical data.
