(2R,3S,4R,5R,6S)-5-Acetamido-6-(((2R,3S,4R,5R,6S)-5-acetamido-6-(benzyloxy)-2-((benzyloxy)methyl)-4-(((R)-1-oxo-1-(1,2,2-triacetylhydrazinyl)propan-2-yl)oxy)tetrahydro-2H-pyran-3-yl)oxy)-2-(acetoxymethyl)tetrahydro-2H-pyran-3,4-diyl Diacetate is a by-product in the synthesis of N-Acetyl-D-glucosaminyl-(1-4)-N-acetylmuramic Acid (A178230). N-Acetyl-D-glucosaminyl-(1-4)-N-acetylmuramic Acid is effective in activating human monocytes with subsequent destruction of tumor cells.
