YS-49 protects cells from oxidant injury.YS-49 is an anti-inflammatory agent. YS-49 is a activator of PI3K/Akt signaling. YS-49, an analog of higenamine, induces heme oxygenase (HO-1) in endothelial cells and protects cells from oxidant injury. The compound was reported to inhibit Ang II-stimulated VSMC proliferation through HO-1 production, which inhibits both the JNK pathway and ROS production. A study (JPET) reported that CKD712 (S-YS-49) confer cardiac protection and anti-inflammatory via activation of the PI3K signal pathway. YS-49 and YS-51 showed inhibitory activities to both human and rat platelet aggregation induced by ADP, collagen and epinephrine. YS-49 and YS-51 have therapeutic potential for DIC and/or accompanying multiple organ failure.

|Cell Lines||RAW 264.7 cells|
|Incubation Time||1 h|
|Results||As shown in Fig. 2, 1 μg/ml LPS significantly induced the morphological change at 2 h, which was subsequently inhibited by CKD712 in a concentration-dependent manner.|

|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|
|Animal A Km|
For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
