Muramyl dipeptide and its derivatives: peptide adjuvant in immunological disorders and cancer therapy.
TLDR
The structural modifications of MDP and its derivatives have been extensively studied in an attempt to increase adjuvant activity and boost the immune response effectively for clinical use in the treatment of cancer and other diseases.Abstract:
Muramyl dipeptide (MDP) is a synthetic immunoreactive peptide consisting of N-acetyl muramic acid attached to a short amino acid chain of L-Ala-D-isoGln. It was first identified in bacterial cell wall peptidoglycan as an active component in Freund's complete adjuvant. In the cell, MDP is detected by NOD2, a cytoplasmic receptor belonging to the human innate immune system. NOD2 mutations are frequently observed in patients with Crohn's disease, an autoimmune disorder, suggesting the significance of the MDP-NOD2 pathway in activating immunity. For this reason, structural modifications of MDP and its derivatives have been extensively studied in an attempt to increase adjuvant activity and boost the immune response effectively for clinical use in the treatment of cancer and other diseases. This review summarizes the synthetic chemistry of MDP and its derivatives and discusses their pharmacological action and stereoselective synthesis.read more

TL;DR: It is shown that rationally designed nanobiologics can promote trained immunity and elicit a durable anti-tumor response either as a monotherapy or in combination with checkpoint inhibitor drugs.

Proteasomal degradation of Nod2 protein mediates tolerance to bacterial cell wall components.
TL;DR: It is shown that activation of Nod2 by its ligand, muramyl dipeptide in the bacterial cell wall, induces rapid degradation of NOD2, which confers MDP tolerance in vitro and in vivo, which indicates that TLRs and NLRs induce a tolerant state through distinct molecular mechanisms that protect the host from septic shock.

Immunity, Inflammation, and Allergy in the Gut
TL;DR: In both mouse and man, mutations in genes that control innate immune recognition, adaptive immunity, and epithelial permeability are all associated with gut inflammation, which suggests that perturbing homeostasis between gut antigens and host immunity represents a critical determinant in the development of gut inflammation and allergy.

TL;DR: Further structural simplifications of the active molecule are reported; natural N-acetyl-muramyl-tripeptides have been found active and the smallest adjuvant molecule found is a synthetic N- acetyl muramyl -dipeptide prepared by Sinay et al.

TL;DR: It is reported that patients with CD of the ileum have reduced antibacterial activity in their intestinal mucosal extracts, and changes in HD5 expression levels, comparable to those observed in CD, had a pronounced impact on the luminal microbiota.
