The antiviral activity of several diaza-adamantanes containing monoterpenoid moieties against a rimantadine-resistant strain of the influenza A/Puerto Rico/8/34 (H1N1) virus was studied. Hetero-adamantanes containing monoterpene moieties at the aminal position of the heterocycle were found to exhibit lower activity compared to compounds with a diaza-adamantane fragment and a monoterpene moiety linked via an amino group at the 6-position of the hetero-adamantane ring. The highest selectivity index (a ratio of the 50% cytotoxic concentration to the 50% inhibitory concentration) out of 30 was observed for compound 8d, which contains a citronella] monoterpenoid moiety. Diaza-adamantane 8d was superior to its adamantane-containing analog 5 both in its anti-influenza activity and selectivity. Furthermore, 8d has more balanced physicochemical properties than 5, making the former a more promising drug candidate. Modelling these compounds against an influenza virus M2 ion channel predicted plausible binding modes to both the wild-type and the mutant (S31N). (C) 2017 Elsevier Ltd. All rights reserved.
