Dihydroconiferyl alcohol as a gibberellin synergist in inducing lettuce hypocotyl elongation. Assessment of structure-activity relationships was written by Shibata, Kozo;Kubota, Takashi;Kamisaka, Seiichiro. And the article was included in Plant and Cell Physiology in 1975.Recommanded Product: 3-(3,4-Dimethoxyphenyl)propan-1-ol This article mentions the following:
Structure-activity relationships of the cotyledon factor were examined by testing the effect of various substances structurally related to the cotyledon factor on gibberellin-induced lettuce hypocotyl elongation. The biol. activity of the cotyledon factor, 3-(4-hydroxy-3-methoxyphenyl) propan-1-ol [2305-13-7], disappeared if the phenolic hydroxy group was masked with a methoxy or glucosyl group. Oxidation of the alc. group in the side chain to a carboxylic group decreased the biol. activity of the cotyledon factor. As to relationships between the biol. activity and length of the alkyl side chain, the propane type was found to be much more active than the methane, ethane or butane type. The presence of a C:C bond in the alkyl side chain made the cotyledon factor biol. inactive. Some antioxidants of indole-3-acetic acid were also assayed for cotyledon factor-like activity, since the cotyledon factor is a polyphenol. However, known antioxidants such as rutin, pyrocatechol, chlorogenic acid, caffeic acid and ferulic acid did not show cotyledon factor-like activity. Structural requirements of the cotyledon factor as a gibberellin synergist were discussed. In the experiment, the researchers used many compounds, for example, 3-(3,4-Dimethoxyphenyl)propan-1-ol (cas: 3929-47-3Recommanded Product: 3-(3,4-Dimethoxyphenyl)propan-1-ol).
3-(3,4-Dimethoxyphenyl)propan-1-ol (cas: 3929-47-3) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. Electron-deficient reagents are also stabilized by ethers. For example, borane (BH3) is a useful reagent for making alcohols. Pure borane exists as its dimer, diborane (B2H6), a toxic gas that is inconvenient and hazardous to use. Borane forms stable complexes with ethers, however, and it is often supplied and used as its liquid complex with tetrahydrofuran (THF).Recommanded Product: 3-(3,4-Dimethoxyphenyl)propan-1-ol
