title: Synthesis and biological activity of potential antimetabolites.
abstract: Several known alpha-amino acid analogues and a new compound, N-chloroacetylphosphoramidate, a carbamyl phosphate analogue, were screened as antitumor agents. All gave 50% growth inhibition of cultures of human epidemeroid carcinoma of the nasopharynx at dosage levels of 2-8 mug/ml while showing no activity against L1210 lymphoid leukemia in vivo in BDFi mice.
