N-(Phosphonoacetyl)amino phosphonates. Phosphonate analogues of N-(phosphonoacetyl)-L-aspartic acid (PALA).
Michaelis-Arbuzov reaction of N-(chloroacetyl)amino phosphonic acids or their esters, followed by acidolysis, gives moderate yields of N-(phosphonoacetyl) derivatives of a variety of (aminoalkyl)phosphonic acids, including analogues of the cytostatic agent PALA, in which the alpha- or beta-carboxylic groups in the aspartate moiety are replaced by a PO3H2 function. Assay of cytostatic activity with human KB cell lines indicates that the substitution of any of the COOH groups in PALA with PO3H2 results in total loss of cytostatic activity. No activity was observed also in the case of other [N-(phosphonoacetyl)amino]alkylphosphonic acids described in this report.
