Selective hydrogenation of vegetable oils over Silia Cat Pd(0)
Pandarus, Valerica,Gingras, Genevieve,Beland, Francois,Ciriminna, Rosaria,Pagliaro, Mario
, p. 1307 - 1311 (2012)
Nanostructured immobilized-Pd catalyst SiliaCat Pd(0) selectively mediates at room temperature the selective and complete hydrogenation of a wide variety of vegetable oils under hydrogen balloon conditions over 0.1 mol % (based on metal content) entrapped catalyst. No cis/trans isomerisation takes place, whereas the catalyst is truly recyclable with low leached amounts of valued palladium, thereby providing the fat and oleochemicals industry with a suitable replacement for Ni-based catalysts.
THIRTEEN KOLAVENE DERIVATIVES FROM SYMPHYOPAPPUS SPECIES
Bohlmann, F.,Zdero, C.,King, R. M.,Robinson, H.
, p. 1657 - 1664 (1981)
Key Word Index - Symphyopappus compressus; S. reticulatus; Compositae; diterpenes; kolavene derivatives; diterpene lactones; tremetone derivative. The aerial parts of Symphyopappus compressus afforded three new kolavene derivatives and those of S. reticulatus ten diterpenes of this type, two of them esterified with long chain fatty acids.Furthermore, a dihydroxyphenylpropanol, also esterified with long chain fatty acids, was present in both species.The roots of S. reticulatus afforded a new tremetone derivative.The structures were elucidated by spectroscopic methods and some chemical transformations.
The temperature-respondent release behavior of a new crystalline complex, docosanoic acid-nicotinamide
Yokoyama,Sunohara,Fujie
, p. 2576 - 2578 (1992)
A new crystalline complex composed of docosanoic acid and nicotinamide (NAA) was prepared. The release of NAA from the complex in an aqueous medium was found to be ON-state above 37°C and OFF-state below 37°C, suggesting that the release behavior is applicable to a temperature-respondent drug delivery system
A PROCESS FOR THE PREPARATION OF DOCOSANOL
-
Page/Page column 7; 8, (2019/01/05)
The present invention provides a process for the preparation of Docosanol (I). The process comprises reducing cis-13-Docosenoic acid (V) to obtain Docosanoic acid (III), which is further reduced to obtain Docosanol (I).

Zhang, Hong-Yan,Yamakawa, Yu-Ichiro,Matsuya, Yuji,Toyooka, Naoki,Tohda, Chihiro,Awale, Suresh,Li, Feng,Kadota, Shigetoshi,Tezuka, Yasuhiro
, p. 604 - 608 (2014/01/23)
In order to develop new drugs for Alzheimer's disease, we prepared 17 fatty acid derivatives with different chain lengths and different numbers and positions of double bonds by using Wittig reaction and stereospecific hydrogenation of triple bonds as key reactions. Among them, (4Z,15Z)- octadecadienoic acid (10) and (23Z,34Z)-heptatriacontadienoic acid (16) showed the most potent neurite outgrowth activities on Aβ(25-35)-treated rat cortical neurons, which activities were comparable to that of a positive control, NGF. Both fatty acids 10 and 16 possess two (Z)-double bonds at the n-3 and n-14 positions, which might be important for the neurite outgrowth activity.

Deshmukh,Veeresh
, p. 1239 - 1241 (2007/10/03)
The synthesis of 1-docosanol 1, starting from palmitaldehyde 2 by dithiane 3 and Wittig approach, is described.
Compositions for coating feedstuff additives for ruminants and feedstuff additives thus coated
-
, (2008/06/13)
A composition for coating a biologically active substance, which is stable in a medium with a pH greater than or equal to 5 and which enables the active substance to be released in a medium with a pH less than or equal to 3.5, consisting of a basic amino copolymer (preferably vinyl-pyridine/styrene copolymer) and a hydrophobic substance with a melting point greater than 60° C. (preferably stearic acid), the hydrophobic substance content being between 50 and 90% of the total mass of the coating, and granules comprising a nucleous containing the biologically active substance, coated with this composition.
Chemical Studies on the Constituents of Hyphear Tanakae HOSOKAWA from Different Host Trees
Fukunaga, Takehiko,Nishiya, Koichi,Kajikawa, Ikuko,Watanabe, Yoshikuni,Suzuki, Nobuo,et al.
, p. 1180 - 1184 (2007/10/02)
The chemical constituents of Hyphear Tanakae HOSOKAWA epiphyting to four different host trees were examined.A new triterpene fatty acid ester (III) and four known flavonoid glycosides, rhamnocitrin-3-O-rhamnoside (V), kaempferol-3-O-rhamnoside (VI), rhamnetin-3-O-rhamnoside (VII), and quercetin-3-O-rhamnoside (VIII) have been isolated from the leaves and twigs of this plant epiphyting to Castanea crenata SIEB., together with fatty acids (I), phytosterol (II), and phytosterol-glucoside (IV).The present investigation has revealed that compounds II-V, VII, and VIII are contained in this plant irrespective of the host, among the four host trees, examined.Keywords - Hyphear Tanakae; misletoe; Loranthaceae; triterpene; lup-20(29)-ene-3β,7β,15α-triol; flavonoid; rhamnocitrin-3-O-rhamnoside; kaempferol-3-O-rhamnoside; rhamnetin-3-O-rhamnoside; quercetin-3-O-rhamnoside
