The results obtained from the alkalifusion of long-chain epoxy-acids indicate the occurrence of at least four different reaction pathways, one of which, a β-elimination reaction, appears to be novel for unactivated epoxides. This particular reaction is also shown to occur with simple acylic ethers, as exemplified by 11-alkoxyundecanoic acids.
Novel oxy- and thio-substituted fatty acid analog substrates of myristoylating enzymes are provided which contain an oxygen or sulfur in place of a methylene group in a carbon position from 4 to 13 in the fatty acid chain of a C.sub.13 -C.sub.14 fatty acid or alkyl ester thereof.
Novel oxy- and thio-substituted fatty acid analog substrates of myristoylating enzymes are provided which contain an oxygen or sulfur in place of a methylene group in a carbon position from 4 to 13 in the fatty acid chain of a C₁₃-C₁₄ fatty acid or alkyl ester thereof.
A method of inhibiting parasitic activity is disclosed in which the biosynthesis of the glycosyl phosphatidylinositol (GPI) anchor of said parasite is inhibited by incorporating into said GPI anchor an oxy-substituted fatty acid analog in place of myristate. The inhibitory compounds are C₁₃ and C₁₄ fatty acids or alkyl esters thereof in which a methylene group normally in carbon position 4 to 13 of said fatty acid is replaced with oxygen.
