5-(3-Bromophenyl)-7-(6-morpholin-4-ylpyridin-3-yl)pyrido[2,3-d]pyrimidin-4-ylamine: structure–activity relationships of 7-substituted heteroaryl analogs as non-nucleoside adenosine kinase inhibitors
摘要:
4-Amino-5,7-disubstituted pyridopyrimidines are potent, non-nucleoside inhibitors of adenosine kinase (AK). We recently identified a potent, orally efficacious analog, 4 containing a 7-pyridylmorpholine substituted ring system as the key structural element of this template. In this report, we disclose the pharmacologic effects of five- and six-membered heterocyclic ring replacements for the pyridine ring in 4. These replacements were found to have interesting effects on in vivo efficacy and genotoxicity as well as in vitro potency. We discovered that the nitrogen in the heterocyclic ring at C(7) is important for the modulation of mutagenic side effects (Ames assay). (c) 2005 Elsevier Ltd. All rights reserved.

was prepared by the nitrosation of chloroethyl methyl ketone with an alkylnitrite. I was treated with the L-leucine ethyl ester (II) to give 2-(2-oximino-3-oxobutylamino)-4-methylvalerate (III) and 2-[N, N-bis(2-oximino-3-oxobutyl)amino]-4-methyl-valerate (IV). In a similar manner, l-bromo-3-oximino-2-butanone (V) was treated with II to give 2-(3-oximino-2-oxobutylamino)-4-methylvalerate (VI). The reaction
1-Chloro-2-oximino-3-butanone (I) 是通过用亚硝酸烷基酯亚硝化氯乙基甲基酮来制备的。I 用 L-亮氨酸乙酯 (II) 处理得到 2-(2-oximino-3-oxobutylamino)-4-methylvalerate (III) 和 2-[N, N-bis(2-oximino-3-oxobutylamino)-4-methylvalerate (III) )氨基]-4-甲基-戊酸酯(IV)。以类似的方式,l-bromo-3-oximino-2-butanone (V) 用 II 处理得到 2-(3-oximino-2-oxobutylamino)-4-methylvalerate (VI)。还研究了III和VI的羰基与羟胺和肼的反应。VI用氨处理得到6-(2-肟基乙基)-3-异丁基-2-羟基吡嗪。还进行了 I 和 V 与其他氨基酸酯的反应。
