Analgesic and Sedative Effect of Thioureido Derivatives of Acetophenone Semicarbazones.
Several synthetic compounds like thiobisformamidine, dithiobiurets and thiobiurets posses a significant analgesic property (1). Some of them (isothiobiurets, thiobiurets) also potentiate the barbiturate hypnosis and this has generally been linked to an enhanced lipophilic property due to the introduction of sulphur. Partition coefficient (a lipophilic parameter for nvalue) is considered to infl...
متن کاملStilbenes and a New Acetophenone Derivative from Scirpus holoschoenus
Separation of the extract of the tubers of Scirpus holoschoenus L. (family Cyperaceae), a species easily confused with Juncus plants, afforded 2-prenyl-3,5,4'trimethoxystilbene, 2-prenyl-3-hydroxy-5,4'-dimethoxystilbene, 2-prenyl-3,4'-dihydroxy5-methoxy-stilbene and 3,5,4'-trimethoxystilbene, in addition to a new acetophenone derivative. The isolated compounds were identified on the basis of sp...
متن کاملAn acetophenone glycoside from Exacum affine.
A new acetophenone glycoside, affinoside, was isolated from the aerial parts of Exacum affine and its structure was determined as 2-O-primeverosylpaenol. The known glucosides, gentiopicroside, 2'-O-E/Z-p-coumaroylloganin and glucopaeonol, were also identified.
متن کاملA potent larvicidal agent against Aedes aegypti mosquito from cardanol.
Cardanol is a constituent of Cashew Nut Shell Liquid that presents larvicidal activity against Aedes aegypti. The isolation of cardanol is somewhat troublesome, however, in this work we describe an efficient and inexpensive method to obtain it as a pure material. The compound was used as starting material to make chemical transformation leading to saturated cardanol, epoxides and, halohydrins. ...
متن کاملTwo antinematodal phenolics from Knema hookeriana, a Sumatran rainforest plant.
The activity-guided chromatographic purification of the methanol extract of Knema hookeriana, using pine wood nematodes Bursaphelenchus xylophilus has successfully led to the isolation and characterization of two phenolic antinematodal compounds with minimum effective dose (MED) of 4.5 and 20 microg/cotton ball (microg/bl.) or 0.018 and 0.073 microM/cotton ball (microM/bl.), respectively. Based...
