This study consists of Part 1 followed Part 2.~Part 1 (Dose escalation study, SA001 60mg~300mg dose group) The part 1 is a dose escalation study. The starting dose is SA001 60mg, and the maximum dose is 300mg. Each dose group is assigned to SA001 or Placebo in a ratio of 3:1. The pharmacokinetics, safety and tolerability of SA001 and its metabolite are investigated after a single oral administration on the fasting state.~Part 2 (Single dose and food effect study, SA001 120mg and 300mg dose group) The purpose of this part 2 is to evaluate the food effect of a high-fat diets(HFDs) on the single oral dose pharmacokinetics of SA001 and its metabolite.
