Mixed signals: The glycophospholipid 1, consisting of two cholinylphospho‐GalNAc units, two 2‐acetamino‐4‐amino‐2,4,6‐trideoxygalactose rings, three glucose residues each with different linkages to other sugar units, and a ribitolphosphate residue, has been synthesized. Target 1 is recognized by the immune system, but not by the TLR‐2 signaling receptor as previously postulated.

Streptococcus pneumoniae LTA is a highly complex glycophospholipid that consists of nine carbohydrate residues: three glucose, two galactosamine and two 2‐acetamino‐4‐amino‐2,4,6‐trideoxygalactose (AATDgal) residues that are each differently linked, one ribitol and one diacylated glycerol (DAG) residue. Suitable building blocks for the glucose and the AATDgal residues were designed and their synthesis is described
