title: N-fatty acyl compounds inhibit myristoyl acylation of pp60v-src and reduce tumorigenicity of Rous sarcoma virus-infected cells.
abstract: Prevention of NH2-terminal myristoylation of pp60v-src was determined with N-fatty acyl glycinal derivatives. Of all the compounds tested, N-myristoyl and N-lauroyl glycinal diethylacetal, N-myristoyl glycyl glycinal diethylacetal, and N-myristoyl-4-aminobutyl aldehyde diethylacetal strongly inhibited myristoylation of pp60v-src; but N-myristoyl diglycyl, N-myristoyl triglycyl, N-decanoyl glycinal diethylacetal, and N-palmitoyl glycinal diethylacetal did not. N-Myristoyl glycinal diethylacetal (25 or 50 microM) suppressed both morphological transformation and colony formation of Rous sarcoma virus-infected chick embryo fibroblasts.
