Pimozide is an antagonist of 6-hydroxyapatide against 6-hydroxyapatide, with Ki values of 1.4 nM, 2.5 nM and 588 nM for 6-hydroxyapatide, D3 and D1 receptors, respectively. Pimozide also has a high affinity for α1-adrenoceptor. Ki value is 39 nM. Pimozide is also an inhibitor of STAT3 and STAT5, and piperimidate triggers ADCD in glioblastoma cell lines (LN-229, MZ-54, GOS-3 and U343) by inducing dephosphorylation and inactivation of mTORC1.

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.
