Disease relevance of SDZ 205-557

 

High impact information on SDZ 205-557

  • RESULTS: 5-HT binding was completely inhibited by 5-HT and partially by 5-HT2A (ketanserin), 5-HT4 (SDZ-205,557), and 5-HT1p (N-acetyl-5-hydroxytryptophyl-5-hydroxytryptophan amide; 5-HTP-DP) receptor antagonists [2].
  • In cells with only 5-HT4/5-HT1p receptors, 5-HT caused only relaxation and residual binding was inhibited by SDZ-205,557 and 5-HTP-DP [2].
  • 8c is an antagonist equipotent to the 5-HT4 receptor antagonist SDZ 205-557 (1) [3].
  • Tissue responses to exogenously added 5-HT (nonneural pathway) and electrical field stimulation (EFS; neural pathway) were performed, and 5-HT receptor subtypes implicated in both responses were determined using three different 5-HT receptor antagonists: methysergide (5-HT(2/1C)), granisetron (5-HT(3)), and SDZ-205,557 (5-HT(4)) [4].
  • Intra-NAc shell microinjections of either RS 67333 (1 or 3 microgram/0.2 microliter/side) or SDZ 205,557 (1-5 microgram/0.2 microliter/side) did not alter spontaneous activity observed after a systemic saline injection but did significantly attenuate the hyperactivity induced by systemic cocaine injection (10 mg/kg) [5].

Anatomical context of SDZ 205-557

 

Associations of SDZ 205-557 with other chemical compounds

  • [3a-Tropanyl]-1H-indole-3-carboxylic acid ester (tropisetron) and 2-methoxy-4-amino-5-chloro-benzoic acid 2-(diethylamino)ethyl ester (SDZ 205-557), two other 5-HT4 receptor antagonists, mimicked the effects of DAU 6285 [8].
  • GR 113808, SDZ 205-557 and DAU 6285 all functioned as competitive antagonists at these 5-HT4 receptors [9].
  • In rat carbachol-contracted oesophagus, 5-HT4-receptor mediated relaxations were surmountably antagonized by SDZ 205,557 with a similar pA2 value (7.3) [1].
  • 9 It is concluded that the relaxant response to 5-HT in the terminal region of the ileum is mediated directly at the smooth muscle; a ranked indole agonist potency and selective antagonism by 5-HT4 receptor antagonists tropisetron, SDZ 205-557 and GR 113808 indicate a 5-HT4 receptor involvement in the relaxation response [10].
  • In this paper, SDZ 205-557 (2-methoxy-4-amino-5-chloro-benzoic acid 2-(diethylamino) ethyl ester) is characterized as the first potent, selective and surmountable antagonist at 5-HT4 receptors in the isolated guinea pig ileum [11].
 

Gene context of SDZ 205-557

  • The objective of this study was to establish the activity profile of SDZ 205-557, a 5-HT4 antagonist, on cutaneous (hotplate) and visceral (writhing) models of pain, after peripheral administration [12].
  • It was also inhibited by the 5-HT(3,4) receptor antagonist tropisetron (10 microM) and the 5-HT(4,3) receptor antagonist SDZ-205-557 (10 microM) but not by preferential antagonists of 5-HT(1P), 5-HT(2A), or 5-HT3 receptors [13].
 

Analytical, diagnostic and therapeutic context of SDZ 205-557

  • SDZ 205-557 also induced hypoalgesia in the writhing test over the entire dose range tested, and visceral hypoalgesia turned out to be analgesia after 1:1 combination [12].
