3-[1-(2-Benzoxazolyl)hydrazino]propanenitrile derivatives: inhibitors of immune complex induced inflammation
摘要:
3-[1-(2-Benzoxazolyl)hydrazino]propanenitrile derivatives were evaluated in the dermal and pleural reverse passive Arthus reactions in the rat. In the pleural test these compounds were effective in reducing exudate volume and accumulation of white blood cells. This pattern of activity was similar to that of hydrocortisone and different from that of indomethacin. The structural requirements for inhibiting the Arthus reactions were studied by systematic chemical modification of 1. These structure-activity relationship studies revealed that nitrogen 1' of the hydrazino group is essential for activity and must be electron rich, whereas chemical modifications of other sites of 1 had only a modest effect on activity.

A URAT1 activity inhibitor containing a nitrogen-containing fused ring compound represented by the following formula [1]:
wherein each symbol is as defined in the description. The present invention is useful for the prophylaxis or treatment of pathology showing involvement of uric acid, such as hyperuricemia, gouty tophus, acute gouty arthritis, chronic gouty arthritis, gouty kidney, urolithiasis, renal function disorder, coronary artery disease, ischemic heart disease and the like.
A new synthetic method is reported in which 2-arylbenz(ox,imid,thi)azoles can be prepared by the palladium catalyzed condensation of aromatic halides with o-amino(phenol, aniline, thiophenol)s followed by dehydrative cyclization. This method is tolerant of a wide variety of functional groups on either aromatic ring and gives good to excellent yields of products.
A compound of Formula (I),
wherein the substituents are as defined herein, which are useful as kinase inhibitors.
