개요
Neopterin is a pyrazino-화학적 성질
off-white to yellow solid용도
D-(+)-Neopterin has been used as a NADPH oxidase inhibitor while assessing the ability of NADPH oxidases in breast cancer cells to produce reactive oxygen species (ROS). [NADPH= nicotinamide adenine dinucleotide phosphate]일반 설명
D-(+)-Neopterin is a pteridine derivative, naturally found in Dictyostelium discoideum. It is found in significant amounts in the urine of cancer patients.Purification Methods
Purification is as for biopterin. Also purify it on a Dowex-1 x 8 (formate form) column and elute with 0.03M ammonium formate buffer pH 8.0 then pH 7.2. The fluorescent neopterin fraction is evaporated under reduced pressure, leaving neopterin and ammonium formate (the latter sublimes out at high vacuum) behind. Stir the residue for 24hours with EtOH, collect the solid and recrystallise it from H2O. [Viscontini et al. Helv Chim Acta 53 1202 1970, cf Wachter et al.
