15034129 | Daniel H, Rancillac A, Crepel F: Mechanisms underlying cannabinoid inhibition of presynaptic Ca2+ influx at parallel fibre synapses of the rat cerebellum. J Physiol. 2004 May 15;557(Pt 1):159-74. Epub 2004 Mar 19. The present study demonstrates that the molecular mechanisms underlying the CB1 inhibitory effect involve the activation of the PTX-sensitive G (i)/G (o) subclass of G proteins, independently of any direct effect on presynaptic Ca (2+) channels (N, P/Q and R (SNX-482-sensitive) types) or on adenylate cyclase or MAPK activity, but do require the activation of G protein-gated inwardly rectifying (Ba (2+)- and tertiapin Q-sensitive) K (+) channels, in addition to 4-aminopyridine-sensitive K (+) channels. |

J Pharmacol Exp Ther. 2006 Feb;316(2):709-17. Epub 2005 Oct 18. In isolated trachea precontracted with carbachol, KMUP-3 (10-100 microM)-caused relaxations were attenuated by epithelium removal and by pretreatments with an inhibitor of K (+) channel, tetraethylammonium (10 mm); K (ATP) channel, glibenclamide (1 microM); voltage-dependent K (+) channel, 4-aminopyridine (100 microM); Ca (2+)-dependent K (+) channel, charybdotoxin (0.1 microM) or apamin (1 microM); soluble guanylate cyclase (sGC), 1H-[1,2,4] oxadiazolo [4,3-a] quinoxalin-1one (ODQ, 1 microM); (NO) synthase, N (omega)-nitro- methyl ester (L-NAME, 100 microM); and adenylate cyclase, SQ 22536 [9-(terahydro-2-furanyl)- (100 microM). |

Br J Pharmacol. 2004 Aug;142(7):1105-14. Epub 2004 Jul 5. Tracheal relaxation induced by KMUP-1 was attenuated by epithelium removal and by pretreatment with inhibitors of soluble guanylate cyclase (sGC) (1H-[1,2,4] oxadiazolo [4,3-a] quinoxalin-1-one (ODQ), 1 microm), synthase (Nomega-nitro- methyl ester, 100 microm), K+ channels (tetraethylammonium, 10 mm), KATP channels (glibenclamide, 1 microm), voltage-dependent K+ channels (4-aminopyridine, 100 microm) and Ca2+-dependent K+ channels (charybdotoxin, 0.1 microm or apamin, 1 microm). These increases in cyclic AMP and cyclic GMP were abolished in the presence of an adenylate cyclase inhibitor SQ 22536 (100 microm) and an sGC inhibitor ODQ (10 microm), respectively. |

Neuroscience. 2002;109(2):299-311. The application of K+ channel blockers such as 4-aminopyridine, Cs+, Ba2+ or tetraethylammonium increased the mIPSC frequency, but failed to inhibit the tACPD action on mIPSC. Forskolin, an activator of adenylate cyclase, facilitated the mIPSC frequency in a concentration-dependent manner and inhibited the tACPD-induced suppression of mIPSC frequency. 8-Br-cAMP, a membrane permeable analog of cAMP, also prevented the inhibitory action of tACPD. |

Eur J Pharmacol. 2005 Sep 27;520(1-3):22-8. This augmentation was observed in the presence of 4-aminopyridine (4-AP, 10 (-3) M) but not that of charybdotoxin (Ch Tx, 10 (-7) M). The isoprostane-induced augmentation was prevented by the ryanodine receptor blocker ruthenium red (10 (-5) M) or the adenylate cyclase blocker SQ 22536 (10 (-4) M). |

Relaxation elicited by HNS-32 was not affected by the adenylate cyclase inhibitor, 9-(tetrahydro-2'-furyl) (SQ 22,536, 10 (-4) M), the soluble guanylate cyclase inhibitor, 1H-(1,2,4)-oxadiazolo-(4,3-a)-quinoxalin-1-one (ODQ, 10 (-5) M) or a cocktail of K+ channel blockers (glybenclamide 10 (-6) M, tetraethylammonium 2x10 (-3) M, apamin 10 (-7) M, 4-aminopyridine 10 (-4) M and Ba2+ 10 (-5) M). |
