Relation of chemical structure to plant growth-regulator activity in the pineapple plant. V. Post-harvest delay of senescence of pineapple fruit was written by Gortner, Willis A.;Leeper, Robert W.. And the article was included in Botanical Gazette (Chicago) in 1969.Formula: C11H11NO2 This article mentions the following:
The effects of 369 compounds, including 94 phenoxyacetic acids, 43 other phenoxy acids, 23 phenylacetic acids, 15 hydrocinnamic acids, 9 benzoic acids, 7 salicylic acids, 48 naphthalene derivatives, 22 indole acids, 5 hydrazine derivatives, and 8 cinnamic acids, for postharvest delay of senescence of pineapple fruit (Ananas comosus) were determined Seventy-six of the compounds were active, and 27 were highly active in delaying senescence. In the phenoxyacetic acid series, high activity was obtained from some halogen-substituted acids but not generally from Me-substituted acids. In the phenoxy-α-propionic acid series, high activity was not observed for a number of halogen- and Me-substituted acids. None of the substituted phenoxy acids other than HOAc and α- propionic showed even moderate activity. An appreciable number of Cl-substituted phenylacetic acids and several benzoic acids showed activity. None of the phenylalkylcarboxylic acids other than HOAc showed even moderate activity. None of the salicylic acid, phthalic acids, or phthalamic acids showed any activity. All hydrazine derivatives were inactive. In the experiment, the researchers used many compounds, for example, 3-(1H-Indol-1-yl)propanoic acid (cas: 6639-06-1Formula: C11H11NO2).
3-(1H-Indol-1-yl)propanoic acid (cas: 6639-06-1) belongs to indole derivatives. Indole, first isolated in 1866, and it is commonly synthesized from phenylhydrazine and pyruvic acid, although several other procedures have been discovered. They are capable of binding to a variety of receptors with high affinity and thus have applications in a wide range of therapeutic areas.Formula: C11H11NO2
