Background:
BIX 02565 is a novel inhibitor of ribosomal S6 kinase 2 with IC50 value of 1 nM [1].
Ribosomal S6 kinase (RSK) is a Na/H exchanger (NHE) -activating factor and is important for pH maintenance during the early phase of cellular stress. While, NHE activation leads to Ca2+ overload and cardiac hypertrophy over longer periods [2].
BIX 02565 is a novel RSK2 inhibitor. Also, BIX 02565 inhibited adrenergic ɑ1A-, ɑ1B-, ɑ1D-, ɑ2A-, β2- and imidazoline I2 receptors with IC50 values ranging from 0.052 to 1.820 μM. These receptors played important roles in the regulation of vascular tone and cardiac function [2]. Also, BIX 02565 inhibited LRRK2 and PRKD1 with IC50 values of 16 and 35 nM [1].
In the rat CV screen, BIX 02565 (1, 3 and 10 mg/kg) significantly decreased heart rate (-93 +13 beats/min) and mean arterial pressure (MAP: to -65 +6 mm Hg below baseline). In telemetry-instrumented rats, BIX 02565 (30, 100 and 300 mg/kg for 4 days) reduced MAP (to -39 + 4 mm Hg) in a concentration-dependent way [2].
