Novel 11β-HSD1 inhibitors: C-1 versus C-2 substitution and effect of the introduction of an oxygen atom in the adamantane scaffold
摘要:
The adamantane scaffold is found in several marketed drugs and in many investigational 11 beta-HSD1 inhibitors. Interestingly, all the clinically approved adamantane derivatives are C-1 substituted. We demonstrate that, in a series of paired adamantane isomers, substitution of the adamantane in C-2 is preferred over the substitution at C-1 and is necessary for potency at human 11 beta-HSD1. Furthermore, the introduction of an oxygen atom in the hydrocarbon scaffold of adamantane is deleterious to 11 beta-HSD1 inhibition. Molecular modeling studies provide a basis to rationalize these features. (C) 2015 Elsevier Ltd. All rights reserved.
Synthesis and pharmacological evaluation of (2-oxaadamant-1-yl)amines
摘要:
The synthesis of several (2-oxaadamant-1-yl) amines is reported. They were evaluated as NMDA receptor antagonists and several of them were more active than amantadine, but none was more potent than memantine. None of the tested compounds displayed antiviral activity. Two of the derivatives showed a significant level of trypanocidal activity. (C) 2009 Elsevier Ltd. All rights reserved.
