ABSTRACT
To screen potential hamster chymase 2 inhibitors, a high-throughput screening (HTS) model was established. Recombinant hamster chymase 2 with active form was cloned and expressed in E. coli. The HTS model with total volume of 50 microL in 384-well microplate was based on fluorescence analysis and was proved sensitive as well as specific (Z' = 0.84). A total of 40 080 samples (including 28 060 compounds and 12 020 natural products) were screened, and 613 samples with inhibition greater than 90% were selected for further rescreening. Finally, compounds J16647 and J16648 were identified with high inhibitory activity on chymase 2, and whose IC50 values were 0.823 and 0.690 micromol x L(-1), respectively.
