Preparation and antitumor activity of o-palmitoyldextran phosphates, o-palmitoyldextrans, and dextran phosphate.

Dextran was modified by introduction of palmitoly and phosphate groups. The derivatives were analyzed by sequential periodate oxidation-sodium borohydride reduction. Only one of these derivatives showed a significant growth-inhibitory effect when administered alone, while a second derivative showed, in combination therapy with an ineffective dose of Mitomycin C, a marked synergistic effect.
