Fenretinide is a synthetic retinoid pharmaceutical linked to ceramide build-up in vivo. Saposin D is an intralysosomal protein necessary for ceramide binding/degradation. We show, via electronic absorption spectroscopy, fluorescence spectroscopy, and ceramide hydrolysis assays, that fenretinide is bound by saposin D {Ka = (1.45 ± 0.49) × 105 M−1}, and affects ceramide solubilization/degradation.

芬维 A 胺与溶酶体蛋白 saposin D 结合可改变神经酰胺溶解和水解



芬维A胺是一种合成类维生素A药物,与体内神经酰胺的积累有关。 Saposin D 是神经酰胺结合/降解所必需的溶酶体内蛋白质。我们通过电子吸收光谱、荧光光谱和神经酰胺水解测定表明,芬维A胺与saposin D { Ka = (1.45 ± 0.49) × 10 5 M -1 } 结合,并影响神经酰胺溶解/降解。
