Evaluation of the selectivity of this compound indicated that it possessed enhanced in vitro antitumor activity and reduced myelosuppressive activity when compared to its prototype amino acid nitrogen mustard, L-phenylalanine mustard (L-PAM). In addition to being more selectively toxic to tumor cells, this compound differs from L-PAM in having a 2-3-fold shorter half-life (t1/2).
