The present invention features compositions, methods, and kits useful in the treatment of viral diseases. In certain embodiments, the viral disease is caused by a single stranded RNA virus, a flaviviridae virus, or a hepatic virus. In particular embodiments, the viral disease is viral hepatitis (e.g., hepatitis A, hepatitis B, hepatitis C, hepatitis D, hepatitis E) and the agent or combination of agents includes sertraline, a sertraline analog, UK-416244, or a UK-416244 analog. Also featured are screening methods for identification of novel compounds that may be used to treat a viral disease.
A series of 1 (2H)-isoquinolones was prepared by reaction of 4-acylisocoumarins with ammonium carbonate or primary amines in acetic acid. These compounds, after a 15-min pretreatment, inhibited histamine release from isolated rat mast cells, and some of them were potent when tested on rat passive cutaneous anaphylaxis (PCA assay 3 h after i. p. injection). The activities of these compounds were, however, lower than that of the already known 4-(4-carboxybenzoyl) isocoumarin.
basidiomycete Gloeophyllum abietinum, oosponol (6b), and the structural analogues (Figure 1) were synthesised in order to investigate which partial structures of the molecules are responsible for their biological activities. Different organisms were employed to test the antibiotic activities of the analogues. From the results obtained with the synthetic analogues of oosponol (6b), it became evident that the
