Abstract

In continuation of studies in these laboratories aiming at the bioevaluation of macromolecular anticancer drug models, in vitro cytotoxicity screens are performed on several series of water-soluble polymer-methotrexate  conjugates. The methotrexate drug in these conjugates is bound through amide or ester linkages to water- soluble polyamide- or polyamidoamine-type carriers by previously developed anchoring techniques.Tests were  conducted against the HeLahumancervical carcinoma cell line generally considered to be drug-sensitive, and  against two variants of the rather refractory Colo 320 DM, a human colon adenocarcinoma line.

KEYWORDS: Drug conjugation, Colo cell line, HeLa cell line, methotrexate, polyaspartamide,  polyamidoamine.
