Reference of 1953-54-4, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 1953-54-4, name is 5-Hydroxyindole. In an article，Which mentioned a new discovery about 1953-54-4
The indolealkylamine 5-hydroxytryptamine (5-HT, 0.1 nM-1 muM) caused dose-dependent increases in the number of contractions observed in guts isolated from the caterpillar Spodoptera frugiperda. Of the 5-HT analogues tested for agonist action, 2-methyl-5-HT (0.1-10 muM) was a full agonist with reduced potency while alpha-methyl-5-HT (0.1-100 muM), 5-carboxamidotryptamine (0.1-100 muM), 5-methoxytryptamine (5-MeOT) (10 nM-10 muM), and tryptamine (1-100 muM) were partial agonists. Incubation of isolated guts with proven mammalian 5-HT receptor antagonists showed that cyproheptadine (10 nM-1 muM), MDL 72222 (1-10 muM), tropisetron (1-10 muM) and 5-benzoyloxygramine (1-10 muM) were potent non-competitive antagonists of 5-HT-induced tissue contraction. In comparison, ketanserin (0.1-1 muM) was a competitive antagonist. The mammalian selective serotonin reuptake inhibitors, clomipramine (10 nM-10 muM) and fluoxetine (10 nM-10 muM) also caused non-competitive inhibition of 5-HT-induced contraction while fluvoxamine (10 nM-10 muM) was a weak competitive antagonist. Low doses of clomipramine (0.1 muM) caused potentiation of 5-HT-induced gut contraction thereby suggesting the presence of 5-HT reuptake systems in this tissue. The contractile effects of 5-HT were inhibited by verapamil, Li+ and H7 and potentiated by theophylline thereby indicating that L-type Ca2+ channels, phosphatidylinositol second messengers and cAMP, respectively, are involved in 5-HT-induced tissue contraction. The 5-HT receptors mediating contractility in the gut of S. frugiperda have properties in common with mammalian 5-HT2 and Drosophila 5- HTdro2A/2B receptors. In addition, these data suggest that the tissue also contains receptors that are similar to mammalian 5-ht6 and 5-HT7 as well as Drosophiladro1 receptors. However, the primary amino acid sequence of these lepidopteran 5-HT receptors will have to be elucidated before full comparisons can be made.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.1953-54-4. In my other articles, you can also check out more blogs about 1953-54-4
