New fluorescent derivatives of dinucleoside monophosphates, (5'-AmNS)UpA/ApU/GpU/CpA, with a fluorophore, 1-aminonaphthalene-5-sulfonic acid (AmNS), attached to the first nucleotide of the dinucleoside monophosphates via a 5'-secondary amine linkage were synthesized in good yield. The chemical structure of (5'-AmNS)ApU was proved by

HPLC-DAD, HPLC-MS/MS, GC-MS and spectrophotometric methods are employed to investigate the degradation process of sodium 1-amino-5-naphthalene sulfonate (1A5NS) aqueous solutions, when exposed to sunlight and UV-lamp (254 nm) irradiations. Experimental results show that both sunlight and 254 nm UV-lamp irradiations

Oxo-octadecadienoic acids (OxoODEs) act as peroxisome proliferator-activated receptor (PPAR) agonists biologically, and are known to be produced in the lipoxygenase/linoleate system. OxoODEs seem to originate from the linoleate alkoxyl radicals that are generated from (E/Z)-hydroperoxy octadecadienoic acids ((E/Z)-HpODEs) by a
