Sennoside A 是一种蒽醌苷，在番泻叶 (Cassia angustifolia) 中发现。Sennoside A 是一种 HIV-1 抑制剂 (IC50=3.8 μM)，抑制 HIV-1 复制。Sennoside A 还抑制 HIV-1 逆转录酶 (RT) 相关 DNA 聚合酶 (RDDP) 和核糖核酸酶 H (Ribonuclease H)，IC50s 分别为 1.9 μM，5.3 μM。 Sennoside A is an anthraquinone glycoside found in Cassia angustifolia leaves. Sennoside A is an HIV-1 inhibitor (IC50=3.8 μ M) that inhibits HIV-1 replication. Sennoside A also inhibits HIV-1 reverse transcriptase (RT) - related DNA polymerase (RDDP) and ribonuclease H, with IC50 values of 1.9 μ M and 5.3 μ M, respectively.
