Abstract: Substituted arylthiourea compounds of Formula I, and the pharmaceutically acceptable salts of such compounds, useful as antiviral agents, are provided herein. Certain substituted arylthioureas disclosed herein are potent and/or selective inhibitors of viral replication, particularly Hepatitis C virus replication. Pharmaceutical compositions containing one or more substituted arylthiourea compounds and one or more pharmaceutically acceptable carriers, excipients, or diluents are provided herein. Such pharmaceutical compositions may contain a substituted arylthiourea as the only active agent or may contain a combination of a substituted arylthiourea derivative and one or more other pharmaceutically active agents. Methods of treating Hepatitis C viral infections in mammals are also provided herein.

Abstract: The present invention provides a process of preparation of naphthochlorins and other chlorins with annelated ring systems useful for photodynamic therapy and the compounds themselves. The method for producing naphthochlorin compounds include contacting compounds such as meso-(2?-hydroxymethyl)phenyl porphyrin or meso-(2?-N,N,N-trialkylaminomethyl)phenyl porphyrin precursors with at least one acid catalyst at sufficient temperature for a sufficient time to yield the desired conversion. In a similar manner chlorins possessing annelated ring systems may be made from compounds such as meso-(2?-hydroxymethyl)aryl porphyrins or meso-(2?-N,N,N-trialkylaminomethyl)phenyl porphyrin. The procedures described herein provide new routes for synthesizing naphthochlorins and chlorins with annelated ring systems.

Abstract: Chlorin compounds and compositions useful in photodynamic therapy for treating ophtalmic, cardiovascular, skin, and cancer or malignant diseases.

Abstract: Carbamate compounds an compositions useful in photodynamic therapy for treating opthalmic, cardiovascular, and skin diseases.

Abstract: The present invention provides a process of preparation of naphthochlorins and other chlorins with annelated ring systems useful for photodynamic therapy and the compounds themselves. The method for producing naphthochlorin compounds include contacting compounds such as meso-(2′-hydroxymethyl)phenyl porphyrin or meso-(2′-N,N,N-trialkylaminomethyl)phenyl porphyrin precursors with at least one acid catalyst at sufficient temperature for a sufficient time to yield the desired conversion. In a similar manner chlorins possessing annelated ring systems may be made from compounds such as meso-(2′-hydroxymethyl)aryl porphyrins or meso-(2′-N,N,N-trialkylaminomethyl)phenyl porphyrin. The procedures described herein provide new routes for synthesizing naphthochlorins and chlorins with annelated ring systems.
