pinacidil and Muscle Relaxation

pinacidil has been researched along with Muscle Relaxation in 74 studies

Pinacidil: A guanidine that opens POTASSIUM CHANNELS producing direct peripheral vasodilatation of the ARTERIOLES. It reduces BLOOD PRESSURE and peripheral resistance and produces fluid retention. (Martindale The Extra Pharmacopoeia, 31st ed)

Muscle Relaxation: That phase of a muscle twitch during which a muscle returns to a resting position.

Research Excerpts

ExcerptRelevanceReference
" As part of our efforts directed toward identifying novel, bladder-selective potassium channel openers (KCOs) targeted for urge urinary incontinence (UUI), we found that bioisosteric replacement of the N-cyanoguanidine moiety of pinacidil (1, Figure 1) with a diaminocyclobutenedione template afforded squaric acid analogue 2, the prototype of a novel series of K(ATP) channel openers with unique selectivity for bladder smooth muscle in vivo."3.70Design and SAR of novel potassium channel openers targeted for urge urinary incontinence. 1. N-Cyanoguanidine bioisosteres possessing in vivo bladder selectivity. ( Antane, MM; Antane, SA; Argentieri, TM; Butera, JA; Freeden, C; Graceffa, RF; Hirth, BH; Jenkins, D; Lennox, JR; Matelan, E; Norton, NW; Quagliato, D; Sheldon, JH; Spinelli, W; Warga, D; Wojdan, A; Woods, M, 2000)
" Spontaneous detrusor muscle contractions were unaffected by glibenclamide (K(ATP) channel blocker) but were reduced when pinacidil (K(ATP) channel opener) concentrations exceeded 10(-5) M."3.70K(ATP) channels mediate the beta(2)-adrenoceptor agonist-induced relaxation of rat detrusor muscle. ( Elliott, RA; Hudman, D; Norman, RI, 2000)
"Vasorelaxant responses to the potassium channel opening drug, pinacidil, were obtained on preparations of pulmonary artery and aorta taken from rats with pulmonary hypertension (induced by chronic hypoxia or monocrotaline) and pre-contracted either submaximally with endothelin-1 (ET-1), PGF2 alpha, U46619 (thromboxane-mimetic) or noradrenaline (NA), or with 80 mM K+."3.69Pinacidil-induced relaxation in pulmonary arteries isolated from pulmonary hypertensive and normotensive rats and pre-contracted with different spasmogens. ( Kay, CS; O'Donnell, SR; Wanstall, JC, 1994)
"3,5-Di-substituted phenylcyanoguanidine derivatives with halogen, cyano and/or nitro groups at the 3- and 5-positions of the benzene ring exhibited very strong smooth muscle relaxation activity in vitro, as compared to pinacidil."3.69Synthesis and structure-activity relationships of novel phenylcyanoguanidine derivatives as potassium channel openers. ( Goto, K; Ikeda, S; Morita, T; Nishimura, N; Sukamoto, T; Yoshiizumi, K; Yoshino, K, 1996)
"Obesity was induced by 24 weeks of high-fat diet feeding in male Sprague-Dawley rats."1.35Altered ATP-sensitive potassium channels may underscore obesity-triggered increase in blood pressure. ( Cao, YX; Fan, LH; Hu, Z; Huo, JH; Ma, AQ; Tian, HY, 2008)
"Adenosine (10 microM) was used as other contractile agent for comparison."1.35Contribution of RhoA kinase and protein kinase C to weak relaxant effect of pinacidil on carbachol-induced contractions in sensitized guinea-pig trachealis. ( Gok, S; Izanli-Paksoy, A; Vural, K, 2009)
"5 microM) had no significant effect on relaxation dose-response curves (DRCs) to ACh, NTG or NO."1.29Role of calcium-activated K+ channels in vasodilation induced by nitroglycerine, acetylcholine and nitric oxide. ( Khan, SA; Mathews, WR; Meisheri, KD, 1993)
"Nifedipine was far more potent than (+/-)-cic in this respect."1.29Comparison of in vitro effects of cicletanine, its enantiomers and major metabolite on rat thoracic aorta. ( Mikkelsen, EO; Poulsen, SH; Sehested, J, 1993)
"Charybdotoxin (ChTX) is a potent blocker of the high-conductance Ca(++)-activated K+ channel in smooth muscle and produces a concentration-dependent contraction of guinea pig trachea."1.28Selective inhibition of relaxation of guinea-pig trachea by charybdotoxin, a potent Ca(++)-activated K+ channel inhibitor. ( Charette, L; Garcia, ML; Jones, TR; Kaczorowski, GJ, 1990)
"Pinacidil was less effective preventing (anti-spasmogenic) than reversing (spasmolytic) contractions to endothelin on either tissue type."1.28Pinacidil antagonism of endothelin-induced contractions of smooth muscle in the lungs: differences between tracheal and pulmonary artery preparations. ( O'Donnell, SR; Wanstall, JC; Zeng, XP, 1990)
"Cromakalim was three to four times more potent than pinacidil."1.28K(+)-channel openers for relaxation of isolated penile erectile tissue from rabbit. ( Andersson, KE; Fovaeus, M; Hedlund, H; Holmquist, F, 1990)
"Pretreatment with pinacidil caused a parallel shift of the tracheal histamine C/E curve to the right, whereas the maximal response to histamine was markedly depressed in the pulmonary artery."1.28A comparison of the relaxant effects of pinacidil in guinea-pig trachea, aorta and pulmonary artery. ( Mellemkjaer, S; Nielsen, CB; Nielsen-Kudsk, JE; Siggaard, C, 1989)
"Pinacidil does not produce vasodilation via an indirect effect mediated by adenosine, prostaglandin, or endothelial-derived relaxant factor (EDRF) release."1.27Pinacidil-induced vascular relaxation: comparison to other vasodilators and to classical mechanisms of vasodilation. ( Cohen, ML; Kurz, KD, 1988)
"Hydralazine was effective at similar concentrations on these three types of contraction."1.27Relaxant effects of pinacidil, nicorandil, hydralazine and nifedipine as studied in the porcine coronary artery and guinea-pig taenia coli. ( Imai, S; Matsui, K; Ogawa, Y, 1986)
