SUBSTITUTED HYDANTOINAMIDES AS ADAMTS7 ANTAGONISTS

The application relates to substituted hydantoinamides of formula (I) as ADAMTS7 antagonists, to processes for their preparation, their use alone or in combination for the treatment or prophylaxis of diseases, in particular of cardiovascular diseases, including atherosclerosis, coronary artery disease (CAD), peripheral vascular disease (PAD), arterial occlusive disease or restenosis after angioplasty. R1 is hydrogen, alkyl, cycloalkyl, heterocycloalkyl, 5- to 6-membered heteroaryl or phenyl; R2 is hydrogen or alkyl; A is 5-membered heteroaryl; Z is 6- to 10-membered aryl or 5- to 10-membered heteroaryl; all groups being optionally substituted.

2H-1,2,3-Triazole-Based Dipeptidyl Nitriles: Potent, Selective, and Trypanocidal Rhodesain Inhibitors by Structure-Based Design

Macrocyclic inhibitors of rhodesain (RD), a parasitic cysteine protease and drug target for the treatment of human African trypanosomiasis, have shown low metabolic stability at the macrocyclic ether bridge. A series of acyclic dipeptidyl nitriles was developed using structure-based design (PDB ID: 6EX8). The selectivity against the closely related cysteine protease human cathepsin L (hCatL) was substantially improved, up to 507-fold. In the S2 pocket, 3,4-dichlorophenylalanine residues provided high trypanocidal activities. In the S3 pocket, aromatic residues provided enhanced selectivity against hCatL. RD inhibition (Ki values) and in vitro cell-growth of Trypanosoma brucei rhodesiense (IC50 values) were measured in the nanomolar range. Triazole-based ligands, obtained by a safe, gram-scale flow production of ethyl 1H-1,2,3-triazole-4-carboxylate, showed excellent metabolic stability in human liver microsomes and in vivo half-lives of up to 1.53 h in mice. When orally administered to infected mice, parasitaemia was reduced but without complete removal of the parasites.
