生物活性

OATD-01 is a highly potent, first-in-class, orally active and selective chitinase inhibitor with low nanomolar activity toward CHIT1 (hCHIT1,IC50=23 nM). OATD-01 shows excellect PK profile in multiple species and is selectivity against a panel of other off-targets. OATD-01 exhibits significant antifibrotic efficacy in vivo and can be used for pulmonary fibrosis (IPF) research.

体外研究

OATD-01 exhibits high affinity toward h/mCHIT1 and h/mAMCase, and the inhibitory constants (Ki) for all four enzymes are 17.3 nM, 26.05 nM, 4.8 nM and 5.7 nM, respectively. These Ki values reveals good correlation with earlier established IC50 data, the IC50 values are 23 nM, 28 nM, 9 nM and 7.8 nM for hCHIT1,mCHIT1, hAMCase and mAMCase, respectively..
Off-target in vitro effects of compound OATD-01 have been evaluated at 10 μM in the Eurofins Panlabs panel of 98 in vitro binding and enzymatic assays, involving diverse molecular classes of proteins.

体内研究

OATD-01 (oral gavage; 30 mg/kg, 100 mg/kg; once daily; 21 days) shows significant antifibrotic efficacy in an animal model of bleomycin-induced pulmonary fibrosis. It reduces the degree of lung fibrosis in a dose-dependent manner, ultimately achieving comparable therapeutic efficacy to reference treatment with Nintedanib in this animal model.
