Two methods for the synthesis of 8-substitutedpyrido[2,3-d]pyrimidines are described. These compounds are close structural analogues of the pteridine precursor involved in the biosynthesis of riboflavin, and were required for studies of the inhibition of riboflavin synthetase.
描述了两种合成8-取代的吡啶并[2,3- d ]嘧啶的方法。这些化合物是参与核黄素生物合成的蝶啶前体的紧密结构类似物,是抑制核黄素合成酶所必需的。

A series of pyrimido[4,5-b]quinoline-2,4-dione derivatives was synthesized and evaluated for their cytotoxic
activities in vitro against five human cancer cell lines. Selected compounds were tested for their MDM2 E3 ligase inhibitory
activities and p53-MDM2 binding inhibitory activities. Among tested compounds, four sulfur-containing compounds
(4-7) displayed enhanced cytotoxic activities and better MDM2 E3 ligase inhibitoty activities in comparison with that of
HLI98c. Three compounds (4-6) showed better p53-MDM2 binding inhibitory potency with IC50 values ranging from 1.3
μM to 9.0 μM.
