Heterocyclic rimantadine analogues with antiviral activity
摘要:
2-(1-Adamantyl)-2-methyl-pyrrolidines 3 and 4, 2-(1-adamatityl)-2-methyl-azetidines 5 and 6, and 2-(1-adamantyl)-2-methyl-aziridines 7 and 8 were synthesized and tested for their antiviral activity against influenza A. Parent molecules 3, 5, and 7 contain the alpha-methyl-1-adimantan-methanamine 2 pharmacophoric moiety (rimantadine). The ring size effect on anti-influenza A activity was investigated. Pyrrolidine 3 was the most potent anti-influenza virus A compound, 9-fold more potent than rimantadine 2, 27-fold more potent than amantadine 1, and 22-fold more potent than ribavirin. Azetidines 5 and 6 were both markedly active against influenza A H2N2 virus, 10- to 20-fold more potent than amantadine. Aziridine 7 was almost devoid of any activity against H2N2 virus but exhibited borderline activity against H3N2 influenza A strain. Thus, it appears that changing the five-, to four- to a three-membered ring results in a drop of activity against influenza A virus. (c) 2006 Elsevier Ltd. All rights reserved.

This invention is based on methods of killing cancer cells by first using either chemotherapeutic agents or radiation treatment to induce senescence in said cancer cells and then subsequently administering a senolytic, such as a Bcl inhibitor, to induce apoptosis of said cancer cell. Formulations of pharmaceutical agents for use according to this invention are also described.
