延命草素 用途与合成方法
Enmein 从 I. serra 中分离,具有免疫抑制作用。
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%.
Cell Viability Assay
Cell Line: | Splenic lymphocyte cells |
Concentration: | 3.13, 6.25, 12.5, 25 μg/ml |
Incubation Time: | 48 hours |
Result: | Exhibited an IC 50 value of 17 μg/ml in splenic lymphocytes. |
Cell Cycle Analysis
Cell Line: | Splenic lymphocyte cells |
Concentration: | 5.5 μg/ml, 11 μg/ml, 22 μg/ml |
