Paragraph 0329, (2017/12/13)
The present disclosure is directed to compounds of formula (I): or a pharmaceutically acceptable salt, solvate or solvate of the salt thereof. Compounds of formula (I) are inhibitors of NOX4 and are useful in the treatment of fibrotic diseases such as scleroderma; lung disease, such as pulmonary fibrosis including idiopathic pulmonary fibrosis (IPF); heart disease, such as heart failure due to ischaemic heart disease, valvular heart disease and hypertensive heart disease, diabetic cardiomyopathy and hypertension; liver disease, such as cirrhosis of the liver; and kidney disease, such as progressive kidney disease glomerulonephritis and diabetic nephropathy; and eye disease such as diabetic retinopathy; skin or subcutaneous scarring, such as keloids, adhesions, hypertrophic scarring or cosmetic scarring; or as an adjuvant or anti-fibrotic in pancreatic cancer to increase chemotherapeutic drug penetration by reducing the density of the connective tissue stroma.

The preparation and assessment of biological activity of 6-substituted 2-naphthamidine inhibitors of the serine protease urokinase plasminogen activator (uPA, or urokinase) is described. 2-Naphthamidine was chosen as a starting point based on synthetic considerations and on modeling of substituent vectors. Phenyl amides at the 6-position were found to improve binding; replacement of the amide with other two-atom linkers proved ineffective. The phenyl group itself is situated near the S1′ subsite; substitutions off of the phenyl group accessed S1′ and other distant binding regions. Three new points of interaction were defined and explored through ring substitution. A solvent-exposed salt bridge with the Asp60A carboxylate was formed using a 4-alkylamino group, improving affinity to Ki = 40 nM. Inhibitors also accessed two hydrophobic regions. One interaction is characterized by a tight hydrophobic fit made with a small dimple largely defined by His57 and His99; a weaker, less specific interaction involves alkyl groups reaching into the broad prime-side protein binding region near Val41 and the Cys42-Cys58 disulfide, displacing water molecules and leading to small gains in activity. Many inhibitors accessed two of these three regions. Affinities range as low as Ki = 6 nM, and many compounds had Ki 100 nM, while moderate to excellent selectivity was gained versus four of five members of a panel of relevant serine proteases. Also, some selectivity against trypsin was generated via the interaction with Asp60A. X-ray structures of many of these compounds were used to inform our inhibitor design and to increase our understanding of key interactions. In combination with our exploration of 8-substitution patterns, we have identified a number of novel binding interactions for uPA inhibitors.
