Seven new polyphosphates containing both nucleic acid base and nitrogen mustard were prepared by reacting the monomers
i.e. l
3-dihydroxyalkyl-5-fluorouracil (IIa
b
g)
1
3-dihydro-xyalkyluracil (IIe
d) and 1
3-dihydroxyalkylthymine (IIe
f) with N
N-bis (2-chloroethyl) phospho-ramidic dichlorid (I). The monomers and polymers were structurally characterized by 'H-NMR
IR spectra and elemental analysis. All of the polymers obtained are soluble in water. The antitumor activity of some of these polymers were tested against Ehrlish ascites in mice.The results showed that the polyphosphates containing both 5-fluorouracil and nitrogen mustard exhibit the lower toxicity and higher antitumor activity. The inhibition ratio of the polymer (IIIa)is 66%.
