DMP-777

Research use only, not for human use.

A potent, selective, and orally active human leukocyte elastase (HLE) inhibitor with IC50 of 23 nM.

A potent, selective, and orally active human leukocyte elastase (HLE) inhibitor with IC50 of 23 nM; displays >40-fold selectivity over thrombin and chymotrypsin; leads to the rapid emergence of spasmolytic polypeptide/trefoil factor family 2 (TFF2)-expressing metaplasia (SPEM) from the bases of fundic glands in gastrin-deficient mice.Cystic Fibrosis Phase 2 Discontinued.

DMP-777-treated rats show a marked decrease in H/K-ATPase staining parietal cells. DMP-777-induced loss of parietal cells is significantly ameliorated with coadministration of omeprazole. DMP-777-treated animals demonstrates marked foveolar hyperplasia in the fundus with prominent expansion of diastase-resistant, PAS-positive surface mucous cells. When DMP-777 is coadministeredwith omprazole, there is a significant decrease in BrdUpositive S-phase cells compared with rats thatreceive DMP-777 alone. After oral dosing of monkeys at 40 mg/kg with DMP-777 the only stereoisomer detected in the post-dose plasma samples is the starting material DMP-777, and no inversion of the configuration at positions 'a' and 'b' of DMP-777 has occurred in vivo. Mist1-/- mice treated with DMP-777 show fewer chief cell to SPEM transitions. Mist1-/- mice treated with L635 demonstrates significantly fewer proliferative SPEM cells compared to control mice.
