KN-93 hydrochloride is a cell-permeable inhibitor of Ca2+/calmodulin-dependent protein kinase II (CaMK-II) with a Ki of 370 nM. KN-93 HCl inhibits fibroblast CaMK-II activity and cell growth in a dose-dependent manner, reversibly arrests cells in G1 and induces apoptosis. KN-93 also blocks cell growth stimulated by basic fibroblast growth factor, platelet-derived growth factor-BB, and epidermal growth factor in NIH 3T3 fibroblasts. KN-93 (0.5 μM) prevents increased LV developed pressure during action potential prolongation and early afterdepolarizations.

| Weight (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| Body Surface Area (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| 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.
