4-[Bis(2-chloroethyl)amino]benzenebutanoic acid (=chlorambucil, 1; 2.5 mM) was allowed to react with single- and double-stranded calf thymus DNA at physiological pH (cacodylic acid, 50% base) at 37 degrees . The DNA-chlorambucil adducts were identified by analyzing the DNA hydrolysates by NMR, UV, HPLC, LC/ESI-MS/MS techniques as well as by spiking with(More)
Kinetics of the hydrolytic reactions of four bisphosphonate derivatives of nucleoside antimetabolites, viz., 5-fluorouridine 5'-beta,gamma-(1-hydroxyethylidene) triphosphate ( 4), 5-fluorouridine 5'-beta,gamma-methylene triphosphate ( 5), ara-cytidine 5'-beta,gamma-(1-hydroxyethylidene) triphosphate ( 6), and ara-cytidine 5'-beta,gamma-methylene(More)
N,N-Bis(2-chloroethyl)-p-aminophenylbutyric acid (chlorambucil, 1; 2.5 mM) was allowed to react with 2'-deoxycytidine, 2'-deoxy-5-methylcytidine, and thymidine (16.1 mM) at physiological pH (cacodylic acid, 50% base), and the reactions were followed by HPLC and HPLC-MS technique. Although the predominant reaction observed was chlorambucil hydrolysis, 1(More)
Phenylacetic acid mustard (PAM; 2), a major metabolite of the anticancer agent chlorambucil (CLB; 1), was allowed to react with 2'-deoxyadenosine (dA), 2'-deoxyguanosine (dG), 2'-deoxycytidine (dC), 2'-deoxy-5-methylcytidine (dMeC), and thymidine (T) at physiological pH (cacodylic acid, 50% base). The reactions were followed by HPLC and analyzed by HPLC/MS(More)
N,N-bis(2-chloroethyl)-p-aminophenylbutyric acid (chlorambucil, 1; 0.6 mM) was allowed to react with 2'-deoxyadenosine (16.1 mM) at physiological pH (cacodylic acid, 50% base), and the reactions were followed by HPLC-MS and HPLC-MS/MS techniques. Although the predominant reaction observed was chlorambucil hydrolysis, ca. 7% of 1 reacted with various(More)
