SERCA2a activator 1 (Compound A) is a sarco/endoplasmic reticulum Ca2+-dependent ATPase 2a (SERCA2a) activator. SERCA2a activator 1 attenuates phospholamban inhibition and enhances the systolic and diastolic functions of the heart. SERCA2a activator 1 can be used for heart failure.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 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 Compound A of 10 mg/kg.
