Agonists of antisense activity are described. Agonists of antisense activity can be utilized in conjunction with antisense compounds to increase the antisense activity of the antisense compound. In some instances, a biological cell is contacted with an agonist of antisense activity and an antisense compound to induce antisense activity in the biological cell. In some instances, an animal is administered an agonist of antisense activity and an antisense compound to induce antisense activity in the animal. Therapeutics and treatments involving agonists of antisense activity and antisense compounds are also described.

Antiviral compounds can be utilized to mitigate viral activity of enveloped viruses in an infected host. In some instances, a virally infected biological cell is contacted with an antiviral to mitigate viral activity in the biological cell. In some instances, a virally infected animal is administered an antiviral to mitigate viral activity in the animal. In some instances, an animal is prophylactically administered an antiviral to mitigate viral activity in the animal. Therapeutics and treatments involving antiviral compounds are also described.

synthesized and evaluated for antiproliferativeactivity, interaction with tubulin, and cell cycle effects. Potent inhibitors of multiple cancer cell lines emerged with the 10-(4-methoxybenzoyl)-10H-phenoxazine-3-carbonitrile (33b, IC50 values in the range of 2–15 nM) and the isovanillic analogue 33c. Seventeen compounds strongly inhibited tubulinpolymerization with activities higher than or comparable
Tricyclic phenothiazine and phenoselenazine derivatives as potential multi-targeting agents to treat Alzheimer's disease

A group of tricyclic phenothiazines (6a, 6b and 7a–l) and phenoselenazines (12a, 12b and 13a–l) was designed, synthesized and evaluated as multi-targeting ligands aimed at the cholinergic, amyloid and oxidative stress pathways of Alzheimer's disease. The phenothiazine derivative 7j (2-chloro-10H-phenothiazin-10-yl-(4-methoxyphenyl)methanone) was identified as the best dual, non-selective cholinesterase
