Pyrimidine derivatives and pharmaceutical composition

Disclosed is an acetyltransferase activity measuring agent which contains an arylamine derivative. As the arylamine derivative, sodium p-aminohippurate can be used preferably. Use of the acetyltransferase activity measuring agent of this invention permits a simple and safe diagnosis of the progress of the pathema of nephritis, which is accompanied by a mesangial proliferative lesion, or renal insufficiency. Furthermore, the scattering of measured values is small, thereby assuring an accurate diagnosis.

Method of testing for nephritis

Disclosed herein are 4,5,6,7-tetrahydro-1H-imidazo[4,5-c]pyridine-6-carboxylic acid amide derivatives having a high antagonistic activity against angiotensin II and a high specificity to angiotensin II receptors, intermediates for preparing the derivatives, and antagonists against angiotensin II comprising the derivatives.
