Abstract

A synthetic polymer nanoparticle formulation utilizing the physiological nitrosothiol chemistry for nitric oxide delivery is shown. Toxicity of S-nitroso nanoparticles against adult female Brugia malayi worms, which are responsible for lymphatic filariasis, is dependent on nitric oxide release through transnitrosation as S-nitrosocysteine, a potent endogenous nitric oxide donor.

摘要

展示了一种利用生理亚硝基硫醇化学用于一氧化氮递送的合成聚合物纳米颗粒制剂。S-亚硝基纳米颗粒对导致淋巴丝虫病的成年雌性马来布鲁线虫的毒性取决于通过转亚硝化作用释放的一氧化氮,转亚硝化作用是以S-亚硝基半胱氨酸这种有效的内源性一氧化氮供体形式进行的。
