Some New Methods in Sialic Acid Chemistry
Gangliosides (G) are sialic acid-containing cell surface glycosphingolipids capable of forming lactones, i.e. inner esters. Some gangliosides are tumor-associated antigens, and they may serve as immunogens in their lactone form, where the latter is comparatively more abundant on the surface of malignant cells. Due to improved hydrolytic stability, lactam (inner amide) analogues of gangliosides sho
