The purpose of this study is to evaluate the administration of single doses of 2-HOBA in humans, with an escalation of doses that begins with the calculated Maximum Recommended Starting Dose. This evaluation will assess tolerability to oral administration of 2-HOBA, obtain pharmacokinetic data, characterize the 2-HOBA metabolic pathways, and determine the relation of dose to prevention of formation of bi-functional electrophile adducts in blood. Characterization of the metabolic fate of 2-HOBA will be supported by investigations that evaluate metabolism in microsomes and cells.
