Synthesis and Biophysical Characterization of Chlorambucil Anticancer Ether Lipid Prodrugs. [JOURNAL ARTICLE]
J Med Chem 2009 Apr 29.
The synthesis and biophysical characterization of four prodrug ether phospholipid conjugates are described. The lipids are prepared from the anticancer drug chlorambucil and have C16 and C18 ether chains with phosphatidylcholine or phosphatidylglycerol headgroups. All four prodrugs have the ability to form unilamellar liposomes (86-125 nm) and are hydrolyzed by phospholipase A(2), resulting in chlorambucil release. Liposomal formulations of prodrug lipids displayed cytotoxicity toward HT-29, MT-3, and ES-2 cancer cell lines in the presence of phospholipase A(2), with IC(50) values in the 8-36 muM range.
