Disease relevance of SR 144528

  • The hypotension, the inhibition of defecation, the anti-inflammatory and peripheral analgesic effects produced by HU-308 are blocked (or partially blocked) by the CB(2) antagonist SR-144528, but not by the CB(1) antagonist SR-141716A [1].
  • Importantly, treatment with SR144528 attenuated both the recruitment of eosinophils and ear swelling in chronic contact dermatitis induced by repeated challenge with oxazolone [2].
  • The migration evoked by 2-AG was abolished in the presence of SR144528, a CB2 receptor antagonist, or by pretreatment of the cells with pertussis toxin, suggesting that the CB2 receptor and Gi/o are involved in the 2-AG-induced migration [3].
  • The selective CB2 antagonist, SR144528 (1 mg/kg-1 i.p.) antagonised effects of HU210 (30 microg/kg-1 i.p.) in the carrageenan induced inflammatory hypersensitivity [4].
  • The AM1241-induced suppression of thermal hyperalgesia was blocked by SR144528 and to a lesser extent by SR14176A [5].

High impact information on SR 144528

  • This effect was mediated at least in part through the CB2 receptors because pretreatment with the CB2 antagonist SR144528 partially reversed the THC-induced apoptosis [6].
  • We found that CP55,940 enhanced the proliferation of both subsets and that this enhancement was blocked by the CB2 receptor antagonist SR 144528 but not by the CB1 receptor antagonist SR 141716 [7].
  • The selective involvement of the CB(2) receptor in this action was evidenced by: (a) the prevention by the CB(2) antagonist SR144528 but not the CB(1) antagonist SR141716; (b) the down-regulation of the CB(2) receptor but not the CB(1) receptor in the tumors; and (c) the absence of typical CB(1)-mediated psychotropic side effects [8].
  • A1 and A2 elevated total intracellular Ca2+ in CB2-positive but not in CB2-negative promyelocytic HL60 cells, an effect that was inhibited by the CB2 antagonist SR144528 [9].
  • The application of SR144528 also reduced the 12-O-tetradecanoylphorbol-13-acetate-induced production of leukotriene B(4) and the infiltration of neutrophils in the mouse ear [10].

Chemical compound and disease context of SR 144528


Biological context of SR 144528

  • The process of CP-55,940-induced receptor phosphorylation followed by SR 144528-induced receptor dephosphorylation kept recurring many times on the same cells, indicating that the agonist switches the system off but the inverse agonist switches the system back on [11].
  • Furthermore, we described that sustained treatment with SR 144528 induced an up-regulation of the cellular Gi protein level as shown in Western blotting as well as in confocal microscopic experiments [12].
  • In addition, SR 144528 is shown to antagonize the stimulating effects of CP 55,940 on human tonsillar B-cell activation evoked by cross-linking of surface Igs (IC50 = 20 nM) [13].
  • The inhibitory effect of both WIN 55,212-2 and CP55,940 on intestinal peristalsis was antagonized by the cannabinoid CB(1) receptor antagonist SR141716A (0.1 microM), but not by the cannabinoid CB(2) receptor antagonist SR144528 (0.1 microM) [14].
  • We have investigated the binding site of the subtype specific antagonist SR 144528, (N-[(1S)-endo-1,3,3-trimethyl bicyclo [2.2. 1]heptan-2-yl]-5-(4-chloro-3-methylphenyl)-1-(4-methoxybenzyl)- pyrazo le-3-carboxamide) on the human cannabinoid CB(2) receptor based on functional studies with mutated receptors [15].

Anatomical context of SR 144528

  • A cannabinoid CB2 agonist, JWH 133, also inhibited electrical field stimulation-induced guinea pig bronchial smooth muscle contraction and its inhibitory effect was blocked by SR 144528 [16].
  • Indeed, we found that through binding to the CB2 receptors, SR 144528 blocked the direct activation of the Gi protein by mastoparan analog in Chinese hamster ovary CB2 cell membranes [12].
  • In vitro, SR 144528 antagonizes the inhibitory effects of the cannabinoid receptor agonist CP 55,940 on forskolin-stimulated adenylyl cyclase activity in cell lines permanently expressing the h CB2 receptor (EC50 = 10 nM) but not in cells expressing the h CB1 (no effect at 10 microM) [13].
  • In vivo, after oral administration SR 144528 totally displaced the ex vivo [3H]-CP 55,940 binding to mouse spleen membranes (ED50 = 0.35 mg/kg) with a long duration of action [13].
  • This effect was counteracted by the selective CB2 antagonist SR144528 (1 mg/kg i.p.). In rat (+)-AM1241 (3 and 6 mg/kg i.v.) and L768242 (30 mg/kg i.p.) reduced allodynia elicited by L5-L6 spinal nerve ligation [17].

Associations of SR 144528 with other chemical compounds

  • In contrast, SR 144528-induced CB2 dephosphorylation was found to involve an okadaic acid and calyculin A-sensitive type 2A phosphatase [11].
  • This up-regulation occurred with a concomitant loss of SR 144528 ability to inhibit the insulin or lysophosphatidic acid-induced MAPK activation [12].
  • A specific cannabinoid (CB)1 receptor antagonist SR-141716A (5 mg/kg ip) reversed the effect of THC, whereas the CB2 receptor antagonist SR-144528 (5 mg/kg ip) was ineffective [18].
  • Pretreatment with the CB1 and CB2 cannabinoid receptor antagonists N-piperidino-5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4-methyl-3-pyrazole-carboxamide (SR141716) and N-[1S)-endo-1,3,3-trimethylbicyclo[2.2.1]heptan-2-yl]-5-(4-chloro-3-methylphenyl)-1-(4-methylbenzyl)-pyrazole-3-carboxamide (SR144528) did not affect the responses to anandamide [19].
  • 3 The inhibitory effects of noladin ether were unaffected by the CB1 antagonists SR141716A and LY320135, and the CB2 antagonist SR144528 (1 microm) [20].

Gene context of SR 144528

  • The same in vivo effect was observed with other cannabinoid receptor ligands such as SR144528, Delta(9)-tetrahydrocannabinol (THC), and Win55212-2 [21].
  • This effect was antagonized by O-1918, by the PI3K inhibitor wortmannin, and by pertussis toxin, but not by the cannabinoid CB1 receptor antagonist AM251 or the cannabinoid CB2 receptor antagonist SR144528 [22].
  • Actin polymerization induced by 2-AG was abolished when cells were treated with SR144528, a CB2 receptor antagonist, and pertussis toxin, suggesting that the response was mediated by the CB2 receptor and G(i/o) [23].
  • Cannabinoid receptor antagonists include the CB1-selective SR141716A, AM251, AM281 and LY320135, and the CB2-selective SR144528 and AM630 [24].
  • 2-AG-induced contraction was unaffected by both the cannabinoid CB1 receptor antagonist SR141716A (3 microM) and the CB2 receptor antagonist SR144528 (1 microM) [25].
