challenges such as the unusual kinetically controlled (1 → 2)-β-oligomannan domain, anomeric phosphodiester, and unique phytoceramide lipid tail linked to the glycan through a phosphate group. The synthesis of PLM anchor was accomplished using a convergent block synthetic approach using three main appropriately protected building blocks: (1 → 2)-β-tetramannan repeats, pseudodisaccharide, and phytoceramide-1-H-phosphonate
首先,在细胞表面phospholipomannan锚[β-曼的总合成p - (1→2)-β-曼p ] ñ - (1→2)-β-曼p - (1→2)-α-曼p -1→ P - (ø →6)-α-曼p - (1→2)肌醇-1- P - (ø →1)的-phytoceramide白色念珠菌被报道。目标
