Main research purpose
1. Quantitative analysis of the total amount of radioactivity in excreta (urine and feces) of male healthy subjects after oral administration of \[14C\]HPP737, to obtain the cumulative excretion rate and main excretion routes of human radioactivity;
2. To identify the main metabolites in the offspring of \[14C\]HPP737 in healthy male subjects, and to determine the main biotransformation pathway and main metabolite structure;
3. To investigate the distribution of total radioactivity in whole blood and plasma and the pharmacokinetics of total plasma radioactivity in healthy male subjects after a single oral administration of \[14C\]HPP737.
Participants will:
1. Take Investigational product once
2. Stay in the clinic about 7 days for checkups and tests
3. Report their symptoms
