Provided herein are novel irreversible sialidase inhibitors. These compounds can be conjugated with a detectable tagging moiety such as azide-annexed biotin via CuAAC for isolation and identification of sialidases. The provided compounds and the corresponding detectable conjugates are useful for detecting sialidase-containing pathogens and imaging in situ sialidase activities under physiological conditions.
