[EN] COMPOUNDS AND METHODS FOR ALTERING LIFESPAN OF EUKARYOTIC ORGANISMS [FR] COMPOSÉS ET PROCÉDÉS PERMETTANT DE MODIFIER LA DURÉE DE VIE D'ORGANISMES EUCARYOTES
Compounds of general formula (I); or a stereoisomers, tautomers, pharmaceutically acceptable salts, or prodrugs thereof, wherein R1, R2, R3, R4, R5, R6, R8 and R9 are as defined herein, are useful for the treatment of diseases and conditions which are mediated by excessive or inappropriate Hsp90 activity such as cancers, viral infection and inflammatory diseases or conditions.
Cyclohexanedione derivatives represent a new family of colchicine-site binders that were identified through a ligand-based virtual screening approach. Structural modifications have now been performed at both distal sites of our identified hit [2-(1-((2-methoxyphenyl)amino)ethylidene)-5-phenylcyclohexane-1,3-dione (4)] in order to improve tubulin binding affinity, anti-proliferative activity and/or
环己二酮衍生物代表了一种新的秋水仙碱位结合剂家族,它们是通过基于配体的虚拟筛选方法鉴定出来的。现在已经在我们确定的命中[2-(1-(((2-甲氧基苯基)氨基)亚乙基)-5-苯基环己烷-1,3-二酮(4)]的两个远端部位进行了结构修饰,以改善微管蛋白的结合亲和力,抗增殖活性和/或水溶性。获得的结果表明,根据对接研究,2-甲氧基苯基环(该片段更靠近αβ-微管蛋白界面)是允许结构变化以提高针对微管蛋白的K a值的化合物(如在化合物20a中,K a = 1.3×10 7M -1(类似于秋水仙碱)或提高水溶性,例如在化合物22c中,其可溶性比以前的命中4高10倍以上。

Provided are compounds which generally have a triketone structure. Examples of the compounds include derivatives of 1,3-cyclohexanedione, such as: 1,3-cyclohexanedione, 2-propanoyl-5-cyclohexyl-; 1,3-cyclohexanedione, 2-propanoyl-5-[4-fluorophenyl]-; 1,3-cyclohexanedione, 2-acetyl-5-[thien-2-yl]-; 1,3-cyclohexanedione, 2-acetyl-5-butyl-; and 1,3-cyclohexanedione, 2-propanoyl-5-[bicyclo[2.2.1]hept-2-en-5-yl]-. The compounds can be used to alter the lifespan of eukaryotic organisms and treat inflammation.
