应用

N-乙酰神经氨酸(NANA,Neu5Ac)是糖缀合物,例如糖脂、糖蛋白和蛋白多糖(唾液酸糖蛋白),的主要成分,其可赋予糖基化组分选择性结合的特征。 Neu5Ac用于对其体内体外生物化学、代谢和摄取的研究。Neu5Ac可用于纳米载体的开发。

生化/生理作用

唾液酸和神经氨酸通常都被宽泛地称为神经氨酸轭合物。研究发现,N-乙酰神经氨酸通常都是细胞表面糖蛋白的末端糖。细胞表面糖蛋白在细胞识别、细胞相互作用和细胞粘附方面都起到重要作用。膜糖蛋白也在肿瘤生长和转移中起重要作用。

Adenoviruses are clinically important agents. They cause respiratory distress, gastroenteritis, and epidemic keratoconjunctivitis. As non-enveloped, double-stranded DNA viruses, they are easily manipulated, making them popular vectors for therapeutic applications, including vaccines. Species D adenovirus type 26 (HAdV-D26) is both a
