Fig. 9. Receptor selectivity of novel compounds. Real-time DMR of emodin (A) and dihydrotanshinone (B) at indicated concentrations on the CHO-FFA1 cells. (C) The DMR amplitudes as a function of acetylshikonin dose in CHO-FFA1 cells. (D) Concentration-response of desensitization and antagonism for acetylshikonin in CHO-FFA1 cells. All data represent mean ± s.d. from three independent measurements, each in duplicate (n = 6).
