title: Inhibition of octapeptide N-myristoylation by acyl amino acids and acyl alkanolamines.
abstract: Several acyl amino acids and acyl alkanolamines were prepared and screened for their inhibition of octapeptide N-myristoylation and HIV-1 replication in MT-4 cells. Of the 62 acyl derivatives tested, N-myristoyl-O-caproyl-L-serine, N-myristoyl-O-caproyl-D-serine and N-decanoyl-O-myristoyl-L-serine were found to be uncompetitive inhibitors of N-myristoylation, but did not prevent HIV-induced cytopathicity in MT-4 cells. However, other acyl derivatives such as N-3-hydroxymyristoyl ethanolamine, N-3-hydroxymyristoyl-D-serine and N-myristoyl-L-cysteine, which did not inhibit N-myristoylation, suppressed the cytopathicity in the infected cells. The acyl derivatives described here may serve as lead compounds for antiviral agents.
