Provided herein are methods of treating a viral infection in a subject in need thereof, comprising administering to the subject a compound of Formula (I), or a pharmaceutical composition comprising Formula (I). Further provided herein are methods for inhibiting the replication of a virus (e.g., a togaviridae family virus (e.g., an alphavirus (e.g., Chikungunya virus, Eastern equine encephalitis, Mayaro virus, Venezuelan equine encephalitis virus, Western equine encephalitis)), a filoviradae family virus (e.g., a Marburg virus (e.g., Marburg virus, Ravn virus)), human respiratory syncytial virus (i.e., human orthopneumo virus), a flavivirus (e.g., dengue virus, Usutu virus, Japanese encephalitis virus, Powassan virus, yellow fever), a paramyxoviridae family virus (e.g., an orthoparamyxovirinae virus (e.g., a henipavims (e.g., Nipah virus), a morbillivims (e.g., measles morbillivirus))) in a subject in need thereof. Also provided herein are methods for treating and/or preventing a disorder due to a microbial toxin (e.g., due to P. aeruginosa exotoxin A, Clostridium septicum alpha-toxin, diphtheria toxin(s), shiga toxin(s)) in a subject in need thereof, comprising administering to the subject a therapeutically effective amount of a compound of Formula (I), or a pharmaceutical composition comprising a compound of Formula (I) as described herein. Also provided are pharmaceutical compositions and kits including a compound of Formula (I) for use in the treatment and/or prevention of a viral infection in a subject in need thereof.

The present invention provides glycan-interacting antibodies and methods for producing glycan-interacting antibodies useful in the treatment and prevention of human disease, including cancer. Such glycan-interacting antibodies include monoclonal antibodies, derivatives, and fragments thereof as well as compositions and kits comprising them. Further provided are methods of using glycan-interacting antibodies to target cells and treat disease.

Described are compositions and methods for inhibition of Hepatitis B virus gene expression. RNA interference (RNAi) agents for inhibiting the expression of Hepatitis B virus gene are described. The HBV RNAi agents disclosed herein may be targeted to cells, such as hepatocytes, for example, by using conjugated targeting ligands. Pharmaceutical compositions comprising one or more HBV RNAi agents optionally with one or more additional therapeutics are also described. Delivery of the described HBV RNAi agents to infected liver in vivo provides for inhibition of HBV gene expression and treatment of diseases and conditions associated with HBV infection.
