Abstract
A series of tanshinone IIA derivatives were synthesized through sulfonation, slat-forming, chlorination, and amidation reactions. Meanwhile, anti-myocardial injury activity was evaluated in vitro. D8 and D9 exhibited a slightly higher anti-myocardial injury (5.78, 7.46 μM) activity compared with esmolol (8.12 μM). In addition, they also displayed a concentration-dependent inhibition on the anti-myocardial injury.
