Alpha1L-adrenoceptor mediation of smooth muscle contraction in rabbit bladder neck: a model for lower urinary tract tissues of man.[Pubmed:9579731]
Br J Pharmacol. 1998 Apr;123(7):1359-66.
1. The alpha1-adrenoceptor population mediating contractile responses to noradrenaline (NA) in smooth muscles of the bladder neck from rabbit (RBN) has been characterized by use of quantitative receptor pharmacology. 2. Experiments with several 'key' alpha1-adrenoceptor antagonists of varying subtype selectivities (RS-17053, BMY 7378, indoramin, 5-methylurapidil, prazosin, REC 15/2739, SNAP 5089, terazosin, WB 4101, tamsulosin, (+)-cyclazosin and RS-100329) were conducted. Schild regression analyses yielded affinity (mean pKb) estimates of 7.1, 6.2, 8.6, 8.6, 8.4, 9.3, 7.0, 7.4, 8.9, 10.0, 7.1 and 9.3, respectively, although deviations from unit Schild regression slope question the robustness of data for RS-17053 and SNAP 5089. 3. The nature of antagonism by these agents and the profile of affinity determinations generated together suggest that a single alpha1-adrenoceptor subtype mediates contractile responses of RBN to NA. Additional studies with phenylephrine indicated also an agonist-independence of this profile. Pharmacologically, this profile was reminiscent of that described as 'alpha1L'-adrenoceptor, which has been shown to mediate contractions of several tissues including lower urinary tract (LUT) tissues of man. Furthermore, a similarity was noticed between the 'alpha1L'-adrenoceptor described here in RBN and the rabbit and human cloned alpha1a-adrenoceptor (based on data from both whole cell radioligand binding at 37 degrees C and [3H]-inositol phosphates accumulation assays), characterizations of which have been published elsewhere. 4. In conclusion, the RBN appears to provide a predictive pharmacological assay for the study of NA-induced smooth muscle contraction in LUT tissues of man.
Pharmacological characterization of an alpha 1A-adrenoceptor mediating contractile responses to noradrenaline in isolated caudal artery of rat.[Pubmed:9138687]
Br J Pharmacol. 1997 Mar;120(5):819-26.
1. The alpha 1-adrenoceptor population mediating contraction of caudal artery of rat has been characterized by using quantitative receptor pharmacology. 2. Cumulative concentration-effect (E/[A]) curves to noradrenaline (NA) yielded a p[A]50 of 5.56 +/- 0.05 (n = 16). Prazosin caused concentration-dependent, parallel, dextral shifts of E/[A] curves to NA yielding a pKb of 8.9 (Schild regression slope = 1.0). RS-17053 (N-[2-(2-cyclopropyl methoxy phenoxy) ethyl]-5-chloro-alpha, alpha-dimethyl-1H-indole- 3-ethanamine hydrochloride; 10-100 nM), a selective alpha 1 A-adrenoceptor antagonist, produced non-parallel, biphasic, dextral shifts of E/[A] curves to NA, suggesting the involvement of more than one alpha 1-adrenoceptor subtype. Analysis of the high affinity component yielded an apparent pA2 value of 9.2 +/- 0.3. 3. A-61603, a selective agonist at alpha 1A adrenoceptors behaved as a full agonist relative to NA and yielded monophasic E/[A] curves with a p[A50] of 7.59 +/- 0.04 (n = 15). Pretreatment of tissues with chloroethylclonidine (CEC; 100 microM for 20 min, followed by 40 min washout), which preferentially alkylates alpha 1B- and alpha 1D-adrenoceptors, did not alter E/[A] curves to A-61603. Prazosin (3-300 nM) caused concentration-dependent, parallel, dextral shifts of E/[A] curves to A-61603 yielding a pA2 estimate of 9.2 +/- 0.2. 4. Experiments with alpha 1-adrenoceptor antagonists of varying subtype selectivities (RS-17053, SNAP 5089, tamsulosin, 5-methylurapidil, BMY 7378, HV 723 and REC 15/2739) revealed parallel dextral shifts of E/[A] curves to A-61603. Schild regression analyses yielded pA2 estimates of 9.2, 9.3, 11.2, 9.0, 6.3, 8.7 and 10.0 for RS-17053, SNAP 5089, tamsulosin, 5-methylurapidil, BMY 7378, HV 723 and REC 15/2739, respectively, although deviations from unit slope (possibly reflecting a secondary involvement of another alpha 1-adrenoceptor) hindered estimations of pKb for some antagonists. The antagonist affinity profile obtained reflects best that described for the alpha 1A-adrenoceptor. 5. In conclusion, caudal artery of rat contracts in response to NA via activation of at least two alpha 1-adrenoceptor subtypes. One of these subtypes displays the pharmacology of the alpha 1A-adrenoceptor, while the other remains to be defined. Use of the novel selective agonist, A-61603, allows for limited pharmacological isolation of the alpha 1A-adrenoceptor permitting characterization of the properties of selective antagonists.
Pharmacological characterization of the uroselective alpha-1 antagonist Rec 15/2739 (SB 216469): role of the alpha-1L adrenoceptor in tissue selectivity, part I.[Pubmed:9190863]
J Pharmacol Exp Ther. 1997 Jun;281(3):1272-83.
Alpha adrenoceptor antagonists have been convincingly shown to be beneficial in reducing both subjective and objective indices of urethral obstruction in benign prostatic hyperplasia. Rec 15/2739 (SB 216469) is a novel alpha-1 adrenoceptor (alpha-1 AR) antagonist currently being developed for benign prostatic hyperplasia. When evaluated in radioligand binding assays with expressed animal or human alpha-1 ARs, Rec 15/2739 shows marked to moderate selectivity for the alpha-1a AR subtype. Its affinity for the recombinant alpha-2 AR subtypes or native dopaminergic D2 receptor was about 100-fold lower than that for alpha-1a AR subtype. In canine tissues, Rec 15/2739 was 20-fold more potent as an inhibitor of [3H]prazosin binding to prostate vis-a-vis aorta. Functional studies in isolated rabbit tissues also confirmed the uroselectivity of Rec 15/2739, with substantially higher affinity (Kb = 2-3 nM) being observed in urethra and prostate, compared with ear artery and aorta (Kb = 20-100 nM). The in vitro selectivity observed with Rec 15/2739 was confirmed in vivo in the anesthetized dog, comparing potency against norepinephrine- or hypogastric nerve stimulation-induced urethral contraction with its ability to reduce diastolic blood pressure. In this model, Rec 15/2739 had greater selectivity than any other alpha-1 AR antagonist examined, including terazosin and tamsulosin. Based on the low potency of prazosin and some of its structural analogs in the rabbit and dog lower urinary tract tissues, it appears that norepinephrine contracts these tissues via activation of the alpha-1L AR. Hence this alpha-1 AR subtype, rather than the alpha-1A AR, may mediate the contraction in vivo.
