Ry. Chen et al., THE SYNTHESIS OF NOVEL DERIVATIVES OF DRO-4-MERCAPTO-2,6-DIOXO-1,3,5,2-TRIAZAPHOSPHORINE AND THEIR ANTITUMOR-ACTIVITY, Phosphorus, sulfur and silicon and the related elements, 89(1-4), 1994, pp. 83-88
A series of new derivatives of dro-4-mercapto-2,6-dioxo-1,3,5,2-triaza
phosphorine have been synthesized. The most stable tautomer was proven
to have the thioenol form by spectroscopic data and quantum chemistry
calculation. The preliminary bioassay indicated that the title compou
nds significantly inhibited the growth of jurkat cells in vitro as wel
l as S-180 tumor in vivo.
