Bikinin is a strong activator of brassinosteroid (BR) signaling. It is an Arabidopsis GSK-3 Inhibitor, an Arabidopsis SHAGGY-related Kinase Inhibitor, and a GSK-3-like Kinase BIN2 Inhibitor. Bikinin directly inhibits BIN2 (group II GSK3s) by interfering with ATP binding. Bikinin is specific toward a subset of Arabidopsis GSK3 kinases including BIN2 and ASK α, γ, ε, ι, and θ.

| 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.
