Usage

General Description

Cetyl Myristoleate is a chemical compound which is a type of fatty acid ester or, more specifically, a cetylated fatty acid (CFA). It's often derived from beef tallow or can also be found in the fats of other animals such as whales and beavers, as well as in certain types of nuts. It's commonly used as an ingredient in dietary supplements for its purported health benefits. Some research suggests that Cetyl Myristoleate may help in relieving pain and inflammation associated with conditions like arthritis and may support immune function. However, conclusive scientific evidence supporting these health benefits is lacking.

Process for Preparation of Hexadecyl Cis-9-Tetradecenoate and Hexadecyl Cis-10-Tetradecenoate

Hexadecyl cis-9-tetradecenoate commonly known as Cetyl myristoleate (CMO) is being used for the treatment of osteoarthritis and other joint inflammatory diseases, cis-9-Tetradecenoic acid (cis-9-myristoleic acid) is the main precursor for the preparation of CMO. As there are limited natural plant sources for cis-9-tetradecenoic acid, the present invention aimed at the synthesis of cis-9-tetradecenoic acid methyl ester from oleic acid methyl ester. As oleic acid is not available in pure form, this has to be isolated from oleic acid-rich oils like olive oil. cis-10-Tetradecenoic acid methyl ester, an isomer of cis-9-tetradecenoic acid was also prepared from undecenoic acid methyl ester, a derivative of castor oil. Undecenoic acid is easily available commercially in pure form. Hexadecyl cis-9-tetradecenoate and hexadecyl c/s-10-tetradecenoate were prepared by enzymatic transesterification of cis-9-tetradecenoic acid methyl ester and cis-10-tetradecenoic acid methyl ester with 1-hexadecanol (cetyl alcohol) respectively. Both the isomers of cetyl myristoleate were evaluated for anti arthritis, blocking inflammation and reduction of adjuvant-induced arthritis in rats.
