CYM5442 是高选择性和口服活性的鞘氨醇 1-磷酸受体激动剂，EC50为 1.35 nM。它激活依赖S1P1的 p42/p44-MAPK 磷酸化，具有视网膜神经保护作用，可轻松穿过中枢神经系统。

CYM5442 is an S1P agonist, targeting to Sphingosine.

HDAC activity is detected as described in the Colorimetric HDAC Activity Assay kit. Each reaction (100 μL) contains nuclear protein (50 μg) extract from leukaemia cells and HDAC substrate. To test the effect of HDACis, Chidamide (CS055) and MS-275 are added to the mixtures and incubated at 37°C for 1 h. The HDAC activities are measured by a microplate readers at 405 nm. The positive control (only nuclear extract and vehicle) is set as 100% and double-distilled water containing 10 μM Trichostatin A, a known strong HDACi, is used as a negative control and set as 0%[2].
