| In vitro study | In intact rat adipocytes, Isoprenaline(300 nM,3 min) increased granule cGMP-and cilostamide-inhibition, low-Km cAMP phosphodiesterase (PDE of cAMP) activity by about 100%. Isoprenaline inhibits insulin-stimulated glucose transport activity in rat adipocytes. Isoprenaline promotes a time-dependent decrease in the accessibility (t1/2 approximately 2 min) of insulin-stimulated cell surface GLUT4 by> 50% in the absence of adenosine, this directly correlates with the observed inhibition of transport activity. Isoprenaline(5 nM and 10 mM) increases the level of cyclic AMP, and Cilostamide(10 mM), a specific PDE (phosphodiesterase 4) inhibitor of cyclic AMP rolipram(10 mM) and ring GMP lifters (50 nM ANF or 30 nMSNP plus 100 nM DMPPO) to enhance this effect. Isoprenaline increased the transcriptional activity of the GIα-2 gene by 140 compared with the control, while the Gsα gene-specific hybridization remained unchanged. Isoprenaline(20 nM) increases the amplitude of total iK and causes a negative shift of the activation curve of IK by about 10 mV, blocking the L-type calcium current regardless of the presence or absence of 300 nM nisoldipine. In rabbit ex vivo pacemaker cells, Isoprenaline(20 nM) increased the spontaneous pacemaker rate in sinoatrial node pacemaker cells by 16%. |
