-
Eight new polyphosphates containing both nucleic acid base and phosphonoacetic acid ethyl ester were synthesized by the polycondensation of P, P-dichloride of phosphonoacetic acid ethyl ester with 1, 3-dihydroxyalkyl-5-fluorouracil, 1,3-dihydroxyalkyl-uracil and 1,3-dihydroxyalkylthymine. These polyphosphates were tested against Ehrlich Ascites Carcinoma in mice. Polymer IIa and IIc exhibited excellent antitumor activity. IIc also showed lower toxicity.
