Implications of the changes in serum neutrophil gelatinase-associated lipocalin and cystatin C in patients with chronic kidney disease.

Aim: Early intervention in patients with chronic kidney disease (CKD) significantly improves the prognosis. The present widely used markers of renal function, such as serum creatinine (sCr), fail to reflect early renal damage and predict the progression of disease. The authors aimed to evaluate whether neutrophil gelatinase-associated lipocalin (NGAL), a novel specific biomarker of acute kidney injury, could predict the progression of CKD.

2-Chloro-5-nitro-pyridin-4-amine.

The title mol-ecule, C(5)H(4)ClN(3)O(2), possesses mirror symmetry, with all of the atoms lying in the mirror plane. There is an intra-molecular N-H⋯O hydrogen bond involving the adjacent -NO(2) and -NH(2) groups. A short C-H⋯O inter-action is also observed.

4-Meth-oxy-3-(trifluoro-meth-yl)aniline.

In title compound, C(8)H(8)F(3)NO, the meth-oxy group is inclined at 8.7 (4)° to the benzene ring plane. The crystal structure is stabilized by inter-molecular N-H⋯F, N-H⋯N and C-H⋯F hydrogen-bonding inter-actions.
