New isomeric trialkoxybenzylamine resins are developed coupling phthalimidomethyl-3,5-dimethoxyphenols to the Merrifield resin, followed by subsequent treatment with hydrazine. The generated benzylamine function allows DCC coupling with the carboxyl funct

A series of muramyl dipeptide (MDP) analogues with structural modifications at the C4 position of MurNAc and on the d-iso-glutamine (isoGln) residue of the peptide part were synthesized. The C4-diversification of MurNAc was conveniently achieved by using CuAAC click strategy to conjugate an azido muramyl dipeptide precursor with structurally diverse alkynes. d-Glutamic acid (Glu), replaced with isoGln, was applied for the structural diversity through esterification or amidation of the carboxylic acid. In total, 26 MDP analogues were synthesized and bio-evaluated for the study of human NOD2 stimulation activity in the innate immune response. Interestingly, MDP derivatives with an ester moiety are found to be more potent than reference compound MDP itself or MDP analogues containing an amide moiety. Among the varied lengths of the alkyl chain in ester derivatives, the MDP analogue bearing the d-glutamate dodecyl (C12) ester moiety showed the best NOD2 stimulation potency.
