Adenosine Deaminase Inhibitors: Synthesis and Biological Evaluation of Unsaturated, Aromatic, and Oxo Derivatives of (+)-erythro-9-(2‘S-Hydroxy-3‘R-nonyl)adenine [(+)-EHNA]
摘要:
The synthesis and biological evaluation of three classes of chain-modified derivatives of(+)EHNA are described. Among the 5',6'-unsaturated derivatives, the Z-isomer was the most potent inhibitor of adenosine deaminase (ADA) but 3-fold less active than (+)-EHNA. Several 9-aralkyladenines (ARADs) have been prepared, and their inhibitory activity was determined. A minimum of two carbon atoms separating the aromatic ring from the adenine-bearing carbon (C-3') was found to be essential for ADA activity equal to or slightly greater than that of (+)EHNA. Finally, replacement of the C-5' carbon with an oxygen resulted in reduced potency.

[EN] This invention disclosed (2S,3R)-3(6-aminopurin-9-yl)aralkan-2-ols, a novel class of adenine derivatives (also called 9-aralkyladenines, ARADS), which have been shown to inhibit the enzyme adenosine deaminase at therapeutically useful levels. The relevant inhibitory constant (Ki) values are in the range of 10<-7> - 10<-10> M. These compounds with potencies in this range can reversibly inhibit ADA in an effective manner, without permanently deactivating the enzyme. ADA inhibitors that have similar biological profiles have been shown to be of therapeutic value when used to protect heart muscle against ischemic damage. [FR] L'invention concerne des (2S, 3R)-3(6-aminopurine-9-yl) aralcan-2-ols, une nouvelle classe de dérivés d'adénine (également appelée 9-aralkyladénines, ARADS) démontrant une capacité d'inhibition de l'ADA à des niveaux thérapeutiquement utiles. Les valeurs de la constante d'inhibition appropriée (Ki) sont comprises entre 10<-7> et 10<-10> M, et les composés dont le potentiel se situe dans cette fourchette peuvent inhiber l'ADA de manière réversible et efficace, sans désactivation permanente de l'enzyme. Les inhibiteurs de l'ADA ayant des profils biologiques similaires démontrent leur valeur thérapeutique dans les applications qui visent à protéger le myocarde contre une détérioration ischémique.
