  多取代嘧啶中C-5取代对前列腺素E 2产生的抑制作用

  摘要：

  作为取代的2-氨基嘧啶更广泛的结构-活性关系研究的一部分，研究了C-5取代对抑制前列腺素E 2（PGE 2）产生的影响。使用Suzuki交叉偶联从相应的2-氨基-4,6-二氯嘧啶开始制备30种化合物。先前显示，具有较小的C-5取代基（氢和甲基）的2-氨基-4,6-二氯嘧啶没有明显的活性，而5-丁基衍生物则具有显着的效力。在这项研究中，在另一方面，既monoaryl-和bisarylpyrimidines是PGE的有效抑制剂2的生产而不管C-5取代基的长度（氢，甲基，Ñ-丁基）。此外，观察到C-5取代基越短，抑制PGE 2产生的效力越高。2-氨基-4,6-二苯基嘧啶是PGE 2产生的最佳抑制剂，IC 50  = 3 nM，无细胞毒性。最有效的抑制剂应作为潜在的抗炎药进行进一步的临床前评估。

  5-Substituted 2-amino-4,6-dihydroxypyrimidines and 2-amino-4,6-dichloropyrimidines: synthesis and inhibitory effects on immune-activated nitric oxide production

  摘要：

  A series of 5-substituted 2-amino-4,6-dihydroxypyrimidines were prepared by a modified condensation of the corresponding monosubstituted malonic acid diesters with guanidine in an excess of sodium ethoxide. The optimized procedure using Vilsmeier-Haack-Arnold reagent, followed by immediate deprotection of the (dimethylamino)methylene protecting groups, has been developed to convert the 2-amino-4,6-dihydroxypyrimidine analogs to novel 5-substituted 2-amino-4,6-dichloropyrimidines in high yields. Pilot screening for biological properties of the prepared compounds was done in mouse peritoneal cells using the in vitro nitric oxide (NO) assay. Irrespective of the substituent at the 5 position, 2-amino-4,6-dichloropyrimidines inhibited immune-activated NO production. The most effective was 5-fluoro-2-amino-4,6-dichloropyrimidine with an IC ₅₀ of 2 µM (higher activity than the most potent reference compound) while the IC ₅₀s of other derivatives were within the range of 9-36 µM. The 2-amino-4,6-dihydroxypyrimidine counterparts were devoid of any NO-inhibitory activity. The compounds had no suppressive effects on the viability of cells. The Mechanism of action remains to be elucidated.

  The invention provides pyrimidine compounds of general formula (I), which reduce simultaneously the production of nitric oxide (NO) and prostaglandin E2 (PGE2). They have no negative effect on the viability of cells in concentrations decreasing the production of these factors by up to 50%; they are not cytotoxic. Furthermore, a method of preparation of the pyrimidine compounds of general formula (I), carrying 2-formamido group, a pharmaceutical composition comprising the substituted pyrimidine compounds according to the invention, and the use of these compounds for the treatment of inflammatory and cancer diseases are provided.˙
