Abstract: The present invention is concerned with This invention relates to C34 peptide derivatives that are inhibitors of viral infection and/or exhibit antifusogenic properties. In particular, this invention relates to C34 derivatives having inhibiting activity against human immunodeficiency virus (HIV), respiratory syncytial virus (RSV), human parainfluenza virus (HPV), measles virus (MeV), and simian immunodeficiency virus (SIV) with long duration of action for the treatment of the respective viral infections.

Abstract: The present invention relates to methods for enhancing the cellular uptake and clearance of soluble oligomeric A? peptide assemblies from the environment surrounding both neuronal and non-neuronal cells. Oligomeric A? peptide assembly uptake and clearance is achieved via an agent that enhances insulin receptor signaling. Such ADDL uptake enhancers represent effective anti-ADDL therapeutics for use in the therapeutic treatment and/or prophylactic treatment of diseases including Alzheimer's disease, Down's syndrome, and the like, in which compromised nerve cell function is linked to the formation and/or the activity of soluble oligomeric A? peptide assemblies, also known as ADDLs, and ADDL-related assemblies.
