Visualizing of sialidase activities in rat brain slices with BTP-Neu5Ac.
A–C, Sialidase activity was imaged in acute coronal slices of adult rat brains with BTP2-Neu5Ac (A), BTP3-Neu5Ac (B) and BTP4-Neu5Ac (C) at pH 7.3. Abbreviations: cc, corpus callosum; ec, external capsule; fi, fimbria; hip, hippocampus; ic, internal ...

Preferential Accumulation of 14C-N-Glycolylneuraminic Acid over 14C-N-Acetylneuraminic Acid in the Rat Brain after Tail Vein Injection. [PDF]
The two main molecular species of sialic acid existing in nature are N-acetylneuraminic acid (Neu5Ac) and N-glycolylneuraminic acid (Neu5Gc). Neu5Ac is abundant in mammalian brains and plays crucial roles in many neural functions.

Chemistry of N-Acetylneuraminic Acid (Neu5Ac)
シアル酸 (Neu5Ac, Neu5Gc, andKDN) は単糖の中で最も複雑な構造もつ化合物である。シアル酸は分子量320程度の小さな分子にもかかわらず多くの官能基から構成されている。またそれらの官能基が条件によって糖特有の平衡状態とる。このことがシアル酸の合成化学を始めるにあたり難くしている。シアル酸は種々の試薬に大変敏感に反応する性質を持っているので、目的化合物を合成するには経験的な反応条件が必要となる。ここでは、既に報告されている沢山の論文の中からシアル酸の中で最も代表的なN-アセチルノイラミン酸についてNeu5Ac特有の反応と基本的な反応の紹介と、簡単な反応によるNeu5Acの挙動からその化学的な多様性について述べる。

Post-Glycosylation Modification of Sialic Acid and Its Role in Virus Pathogenesis
Sialic acids are a family of nine carbon keto-aldononulosonic acids presented at the terminal ends of glycans on cellular membranes. α-Linked sialoglycoconjugates often undergo post-glycosylation modifications, among which O-acetylation of N-acetyl ...

ABSTRACT Type I collagen (Col‐I) is widely used in biomaterials and cell biology, yet the glycosignature of commercial Col‐I preparations remains poorly characterized. Here, we established an integrated lectin‐based workflow to profile the glycan landscape of commercially sourced bovine pepsin‐soluble Col‐I as supplied for biomaterial use.

ST6GAL1 sialylates glycoconjugates in the Golgi, modulating immune recognition and enabling tumor immune evasion. To effectively reach ST6GAL1, inhibitors should demonstrate good membrane permeability. Based on nonpermeable hit JFD 00458, we developed sulfonylurea analogs achieving increased membrane permeability and potency.
