N-glycolyted muramyldipeptide -NOD2 agonist
The NOD2 agonist, MDP (muramyl dipeptide), is the minimal bioactive peptidoglycan motif common to all bacteria and the essential structure required for adjuvant activity in vaccines. The cell wall of mycobacteria is extremely immunogenic and this potent activity is attributed to their MDP which is N-glycolylated. N-glycolyl-MDP displays strong NOD2-mediated activity and is considered a potent Th1-biased adjuvant.
N-Glycolyl-MDP VacciGrade™ is suitable for preclinical studies. It is prepared under strict aseptic conditions. It is guaranteed sterile and thoroughly tested for the presence of endotoxins.
N-Glycolyl-MDP VacciGrade™ is for research use only, not for use in humans.Back to the top

MDP (muramyl dipeptide), is the minimal bioactive peptidoglycan motif common to all bacteria and the essential structure required for adjuvant activity in vaccines.
MDP has been shown to be recognized by NOD2, but not TLR2, nor TLR2/1, or TLR2/6 associations .
The cell wall of mycobacteria is known to be extremely immunogenic. This potent activity is attributed to their MDP which is N-glycolylated in contrast to the MDP of most bacteria which is N-acetylated. N-glycolyl-MDP has been reported to display a stronger NOD2-mediated activity than N-acetyl-MDP and thus to be a more potent vaccine adjuvant than N-acetyl-MDP . Furthermore MDP leads to the activation of the NLRP3 inflammasome .
