Abstract:
The effects of bepridil, ni-modipine and nicardipine on the activity of CaM - dependent protein kinase Ⅱ from mouse cerebrum were studied in vitro. Tt was found that bepridil significantly inhibitied the activity of CaM - PK Ⅱ with an IC50 value of 0. 3 mmol ? L-1. but nimodipine and nicardipine did not basi-cally influence the activity of the enzyme. The experimental results showed that the inhibitory effect of bepridil on the activity of CaM - PK Ⅱ was an antagonistic action of bepridil to CaM.
