Biological Activity

NP-118809 (39-1B4) is a potent N-type calcium channel blockers (IC50= 0.11 uM) which has good selectivity over L-type calcium channels. NP-118809 exhibites increased N-type channel blockade (IC50=0.11 uM) and is 111-fold more selective for N-type channels (L-type calcium channel IC50=12.2 uM). NP118809 further exhibits a number of favorable preclinical characteristics as they relate to overall pharmacokinetics and minimal off-target activity including the hERG potassium channel.

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.
