General Description

9-Octadecynoic acid methyl ester, also known as 9-OMe-18:1, is a chemical compound that belongs to the class of alkynoic acids. It is a fatty acid ester that is derived from 9-octadecynoic acid, a type of fatty acid commonly found in plant oils. 9-Octadecynoic acid methyl ester is used in the production of various industrial products, including lubricants, coatings, and plastics. It has also been studied for its potential use in pharmaceutical applications, particularly for its anti-inflammatory and anti-cancer properties. Additionally, 9-Octadecynoic acid methyl ester has been investigated for its potential use as a bio-based fuel additive due to its high energy density and low emissions characteristics.

Synthesis and Evaluation of Radioiodinated (E)-18-Iodo-17-octadecenoic Acid as a Model Iodoalkenyl Fatty Acid for Myocardial Imaging

125I-labeled (E)-18-iodo-17-octadecenoic acid (13) has been prepared and evaluated in rats to determine the myocardial uptake and retention and degree of in vivo deiodination of this model iodovinyl-substituted fatty acid, which contains no structural perturbation to inhibit metabolism.This new agent was prepared by NaI-chloramine-T treatment of (17-carbomethoxyheptadec-1-en-1-yl)boronic acid (11) prepared by catecholborane treatment of methyl 17-octadecynoate (10), followed by basic hydrolysis to the free acid (13).The pivotal substrate, 17-octadecynoic acid (9), was prepared by two new routes .The 125I-labeled acid 13 showed high myocardial uptake (1 h, 1.90-2.28percent dose/g) with 45percent washout after 2 h but lower heart/blood ratios in comparison to analogues containing the tellurium heteroatom.Deiodination was low for the first 2 h after injection (2 h, 61percent dose/g).Excellent myocardial images were obtained in a dog with the 123I-labeled agent.

Ultrasound in fatty acid chemistry: facile dehydrobromination of dibromo fatty esters to acetylenic ester derivatives

Dehydrobromination of dibromo derivatives of olefinic fatty acids was accomplished using KOH in 20percent aqueous ethanol under cocomitant ultrasonic irradiation (20 kHz) for 30 min at ambient temperature to give the corresponding acetylenic fatty acid derivatives (52-72percent yield).Ten different dibromo fatty acid substrates were used.Products include: fatty acids with a terminal or internal acetylenic bond; acetylenic fatty acids containing an additional functional group, such as hydroxy, chloro or azide group.The structures of the products were characterized by infrared and NMR spectroscopy. - Keywords: acetylenic fatty esters; dehydrobromination; dibromo fatty esters; ultrasond
