BACKGROUND
Topoisomerase poisons are important drugs for the management of human malignancies. Nitric oxide (•NO), a physiological signaling molecule, induces nitrosylation (or nitrosation) of many cellular proteins containing cysteine thiol groups, altering their cellular functions. Topoisomerases
Water-soluble T-antigen containing glycopolymers [Gal beta(1,3)-GalNAc alpha) having a high degree of lipophilicity were synthesized from poly[N-(acryloxy)succinimide] (6-10) by amidation with an amine-ending T-antigen derivative (3) and various amines of increasing alkyl chain length (ammonia and
Novel nitrogen mustard agents 7-12 involving 4-(N,N-bis(2-chloroethyl)aminophenyl)propylamine linked to a 5-(4-N-alkylamidinophenyl)-2-furancarboxylic acid moiety by the formation of an amide bond have been synthesized, characterized, and evaluated for their in-vitro cytotoxic activity against
BACKGROUND
Etoposide and doxorubicin, topoisomerase II poisons, are important drugs for the treatment of tumors in the clinic. Topoisomerases contain several free sulfhydryl groups which are important for their activity and are also potential targets for nitric oxide (NO)-induced nitrosation. NO, a
