, p. 315 - 319 (2002)
Racemic mixtures and laevorotatory enantiomers of cis- and trans-4-hydroperoxyifosfamide and 4-hydroperoxybromofosfamide possess high antitumour activity both in vitro and in vivo. However, no major differences in biological activity were observed among t

Page/Page column 22-23, (2010/09/17)
The present disclosure concerns complexes of 4-hydroperoxy ifosfamide. In one embodiment the complexes can be represented by the formula (A); wherein A represents an ammonium species selected from the conjugate acid of a basic amino acid, quaternary ammonium, aliphatic ammonium, heterocyclic ammonium, aromatic ammonium, substituted and unsubstituted pyridinium, guanidinium, and amidinium, and wherein X and Y independently represent leaving groups. Also disclosed herein are methods for making such compounds and formulating pharmaceutical compositions thereof. Methods for administering the disclosed compounds to subjects, particularly to treat hyperproliferative disorders, also are disclosed.

31P nuclear magnetic resonance spectroscopy was used to measure the pKa (4.28 +/- 0.2) of isophosphoramide mustard (IPM) at 20 deg C and to study the kinetics and products of the decomposition of IPM at a solution pH value of ca. 7.4 and at temperatures between 20 and 47 deg C in the presence of nucleophilic trapping agents.At 37 deg C, the half-life for the first alkylation was ca. 77 min and ca. 171 min for the second alkylation; these data may be compared with those for phosphoramide mustard (Engle, T.W.; Zon, G.; Egan, W.J.Med.Chem. 1982, 25, 1347), wherein the half-lives for the first and second alkylations are approximately the same (18 min).The rate of fragmentation of aldoifosfamide to IPM and acrolein was also studied by NMR spectroscopy (pH 7.0; 37 deg C; 0.07 M phosphate); under the noted conditions, the half-life of aldoifosfamide was fouund to be ca. 60 min.
