生物活性
Enmein 从 I. serra 中分离,具有免疫抑制作用。体外研究
Enmein shows significant inhibitory effect toward K562 with an IC 50 value ranging from 3.2 μg/ml to 8.2 μg/ml. Enmein (3.13-25 μg/ml; 48 hours) has inhibitory effect on lymphocytes with significant difference within concentration from 6.25 μg/ml to 25 μg/ml. Enmein (5.5-22 μg/ml; 48 hours) causes the percentage of S stage cells decreased from 19% to 6%, causes the percentage of G2/M stage cells to decrease from 2% to 0.4%.
