Synthesis, conformational characteristics and anti-influenza virus A activity of some 2-adamantylsubstituted azacycles
The broad-spectrum antiviral activity of 2-(2-adamantyl)piperidines 11, 13a,b, and 15, 3-(2-adamantyl)pyrrolidines 27, 21a-g and 2-(2-adamantylmethyl)piperidines 30, 32a-c, and 35a-d was examined. Several compounds in the new series were potent against influenza A H3N2 virus. When 1-aminoethyl pharmacophore group of 2-rimantadine 4 (2-isomer of rimantadine) is included into a saturated nitrogen heterocycle, see compound 11, potency was retained. The diamine derivatives 21e-g and particularly 35a-c possessing three pharmocophoric groups, that is, the adamantyl and the two amine groups, exhibited high potency. The new compounds did not afford specific activity at non-toxic concentrations against any of the other viruses tested. According to NMR spectroscopy and molecular mechanics calculations it is striking that the parent structures 11 and 27 adopt a fixed trans conformation around C2{single bond}C2? bond. In the parent amines, which proved to be active compounds, the distance between nitrogen and adamantyl pharmacophoric groups was different; N{single bond}C2? distance is 3.7, 3.8 A for 27, 30 and 2.5 A for 11 suggesting that M2 receptor site can accommodate different in size and orientation lipophilic cages.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2008-75-5, help many people in the next few years.Recommanded Product: 2008-75-5
