Intracellular pathogenic microorganisms and toxins exploit host cell mechanisms
to enter, exert their deleterious effects as well as hijack host nutrition for
their development. A potential approach to treat multiple pathogen infections and
that should not induce drug resistance is the use of small molecules that target
host components. We identified the compound 1-adamantyl (5-bromo-2-methoxybenzyl)
amine (ABMA) from a cell-based high throughput screening for its capacity to
protect human cells and mice against ricin toxin without toxicity. This compound
efficiently protects cells against various toxins and pathogens including
viruses, intracellular bacteria and parasite. ABMA provokes Rab7-positive late
endosomal compartment accumulation in mammalian cells without affecting other
organelles (early endosomes, lysosomes, the Golgi apparatus, the endoplasmic
reticulum or the nucleus). As the mechanism of action of ABMA is restricted to
host-endosomal compartments, it reduces cell infection by pathogens that depend
on this pathway to invade cells. ABMA may represent a novel class of
broad-spectrum compounds with therapeutic potential against diverse severe
infectious diseases.
