Synthetic routes are
described to 5,6-diamino-2,4'-bipyrimidin-4-ones and thence to
2-(pyrimidin-4'-yl)purines and 2-(pyrimidin-4'-yl)pteridines, some of which bear a sulfur- or nitrogen-linked
basic side chain; also reported are routes to a series of phenyl- and diphenyl-pyrimidines, to each of which is attached a similar
sulfur-, nitrogen-, or oxygen-linked side chain. Members of all the above
systems show activity as amplifiers of phleomycin in
a bacterial screen but the phenylpyrimidines with a
sulfur-linked side chain are especially active.
合成路线
描述了 5,6-二氨基-2,4'-联嘧啶-4-酮的合成路线,然后是
2-(嘧啶-4'-基)嘌呤和 2-(嘧啶-4'-基)蝶啶的合成路线。
还报道了一系列苯基和二苯基嘧啶的制备方法,每种嘧啶都附有类似的
硫链、氮链或氧链侧链。上述所有
系统在细菌筛选中都显示出了作为博莱霉素扩增剂的活性。
细菌筛选中,上述所有系统的成员都显示出了作为普利霉素扩增剂的活性,但具有硫连侧链的苯基嘧啶类
硫连侧链的苯基嘧啶具有特别的活性。
