27648599-4	2016	A series of the ligands, alpha-galactosyl ceramide (alpha-GalCer) derivatives containing polar groups in the acyl chain, was synthesized, and the structure-activity relationship studies demonstrated that simple modification from a methylene to an amide group in the long fatty acyl chain, when introduced at optimal positions, enhanced the CD1d recognition of the glycolipid ligands.	Amides	45-50	CD1d molecule	Homo sapiens	340-344	
28655912-4	2017	While introduction of the amide-motif in the phytosphingosine chain is tolerated for CD1d binding and TCR recognition, the studied alpha-galactosylsphingamides showed compromised antigenic properties.	Amides	26-31	CD1d molecule	Homo sapiens	85-89
