ALD-R491
A vimentin inhibitor.
General information
ALD-R491 is a small molecule targeting vimentin. It is not cytotoxic and does not change vimentin levels. ALD-R491 inhibits endocytosis, endosomal trafficking, and release of exosomes (Li et al., 2021).

It also inhibited SARS-CoV-2 pseudovirus infection with an IC50 of 13.5 nM (at MOI of 0.5) and high selectivity. Experimental data suggest that it boosts the pathogen-killing capacity of macrophages and activates regulatory T cells. The compound displayed efficacy against SARS-CoV-2 infection in aged mice and in a rat model of lung injury. |
