Abstract
A highly lymphotropic derivative of a proteinaceous antitumor agent, neocarzinostatin, was prepared by chemical conjugation of a water-soluble synthetic poly(maleic acid)-styrene oligomer. The derivative of 2.5 .times. 104 dalton exhibited a strong antitumor activity against [rat ascites tumor] AH109A and of [rat leukemia cells] DBLA-6 and antimetastatic activity against lymphatic metastatis of AH109A in rats. An increased lipophilicity and MW of the derivative appear to be responsible for its improvement as lymphotropic antimetastatic agent.
