The invention relates to novel Muramyl Dipeptide (MDP) derivative compound of structural Formula-VIII, a process for synthesis, intermediates used in the synthesis and use thereof. R = alkyl (both linear and branched), aryl, substituted aryl, alkoxy alkyl Wherein, R can be both linear and branched alkyl, aryl, substituted aryl and alkoxy alkyl. These compounds possess excellent pharmacological properties, in particular immunomodulating properties for use as adjuvant in vaccine formulations. These compounds are, particularly useful as adjuvants in vaccines.
this paper, the synthesis and conformational analysis of desmuramyl peptides, derivatives lacking the N-acetylmuramyl moiety, is described. Systematic conformational analysis (bottom-up approach) of peptides in zwitterionic and non-zwitterionic forms of corresponding desmuramyl di-, tri-, and tetrapeptides was performed and results were compared with experimental data obtained by NMR study.

network connected together by peptidic cross-links. PG is a dynamic structure that is essential for resistance to environmental stressors. Remodeling of PG occurs throughout the bacteriallife cycle, particularly during bacterial division and separation into daughter cells. Numerous autolysins with various substrate specificities participate in PG remodeling. Expression of these enzymes must be tightly

(EN) The present invention provides a method for the preparation of disaccharides, such as glucosaminyl muramic acids peptides and derivatives. The method includes condensing a protected muramic acid ester with a 1-organothio- or 1-fluoroglucosamine derivative in the presence of a suitable promoter to produce a protected glucosaminyl muramic acid ester. The protected glucosaminyl muramic acid ester may be used to prepare disaccharide peptides, such as N-acetylglucosaminyl-N-acetylmuramyl dipeptides, which have demonstrated immunological activity. Protected muramic acid esters and 1-organothio- or 1-fluoro-glucosamine compounds which may be employed as intermediates in the method are also provided.(FR) L'invention concerne un procédé de préparation de disaccharides, tels que des peptides et des dérivés d'acide muramique de glucosaminyle. Ce procédé consiste à condenser un ester protégé d'acide muramique avec un dérivé de 1-organothio- ou 1-fluoroglucosamine en présence d'un promoteur approprié, de manière à obtenir un ester protégé d'acide muramique de glucosaminyle. On peut utiliser cet ester protégé afin de préparer des peptides de disaccharides, tels que des dipeptides de N-acétylglucosaminyl-N-acétylmuramyle, qui se sont avérés présenter une activité immunologique. L'invention concerne également des esters protégés d'acide muramique et des composés de 1-organothio- ou 1-fluoroglucosamine que l'on peut utiliser en tant qu'intermédiaires dans le procédé.
