LJ001 an aryl methyldiene rhodanine derivative

A small anti-viral molecule effective against enveloped (but not naked) viruses.

Wolf et. al.

LJ001 acts on virus membranes in an irreversible manner

Wolf et. al.

Broad Spectrum Influenza A Filoviruses Poxviruses Arenaviruses Bunyaviruses Paramyxoviruses Flaviviruses HIV-1 Hepatitis C Ebola And others

Viruses lack a ‘biogenic’ membrane

Viruses can’t make their own proteins or repair their membrane like a cell can

How?

How we would use this Still very early in development, further

testing needed

Shorten Viral Infection Course Preventative Measure?

Could be put in condoms

New treatment for multiple viruses Eliminate temporary infections Fight Chronic ones

LJ001 is effective at very low doses Potentially Excellent Therapeutic Index
