Activation Mechanisms of Mafosfamide and the Role of Thiols in Cyclophosphamide Metabolism

cis-Mafosfamide (cis-5) (ASTA Z7557), a stable analogue of cis-4-hydroxycyclophosphamide (cis-2), undergoes rapid decomposition in aqueous phosphate buffer or plasma at pH 7.4 and 37 deg C.The reaction kinetics of cis-5 are complex, and trans-mafosfamide (trans-5) and cis-2 are produced and subsequently disappear over the course of the reaction.The rates of decomposition of cis-5 as well as cis-2 were much faster in plasma than in buffer.The cis-trans isomerization of cis-5 occured by a specific-base-catalyzed process via iminocyclophosphamide (8) as a transient intermediate.In contrast, formation of cis- and trans-mafosfamide (5) from cis-2 and MESNA (sodium 2-mercaptoethanesulfonate) proceeded by an acid-catalyzed process via the hemithioacetal intermediate (6).The significance of these findings with respect to cyclophosphamide metabolism is discussed.

Base-catalyzed hydrolysis of 4-hydroperoxycyclophosphamide: Evidence for iminocyclophosphamide as an intermediate

cis-4-Hydroperoxycyclophosphamide (5) undergoes facile reaction with acqueous phosphate or Tris buffers at pH 7-8 and 30 °C. The kinetics of 5 are complex,and the trans-4-hydroperoxy isomer 6 is produced and subsequently disappears over the course of the reaction. Addition of hydrogen peroxide to the reaction mixture retards the disappearance rate of 5 and increases the amount of 6 generated. Rate constants for the reversible disappearance of 5 and appearance of 6 and 4-hydrocyclophosphamide (2) have been determined by nonlinear least-squares methods. The reaction is catalyzed by hydroxide ion, Tris free base, and HPO42-, with catalytic constants of 0.032 min-1 (pH 8.0), 0.052, and 0.115 M-1, respectively. The major product in the presence of Tris is the oxazolidine arising from the addition of Tris to aldophosphamide, not 2 as assumed previously. These results are consistent with a mechanism involving general-base-catalyzed elimination to produce iminocyclophosphamide as a transient intermediate; the imine can react with the hydrogen peroxide evolved in the reaction to give 5 and 6, with water to give 2, or, in general, by addition of a nucleophile to C-4. The significance of these findings with respect to other 4-substituted cyclophosphamides is discussed.
