The carbapenem class of β-lactams has been optimized against Gram-negative bacteria producing extended-spectrum β-lactamases by introducing substituents at position C2. Carbapenems are currently investigated for the treatment of tuberculosis as these drugs are potent covalent inhibitors of l,d-transpeptidases involved in mycobacterial cell wall assembly. The optimization of carbapenems for inactivation of these unusual targets is sought herein by exploiting the nucleophilicity of the C8 hydroxyl group to introduce chemical diversity. As β-lactams are structure analogs of peptidoglycan precursors, the substituents were chosen to increase similarity between the drug and the substrate. Fourteen peptido-carbapenems were efficiently synthesized. They were more effective than the reference drug, meropenem, owing to the positive impact of a phenethylthio substituent introduced at position C2 but the peptidomimetics added at position C8 did not further improve the activity. Thus, position C8 can be modified to modulate the pharmacokinetic properties of highly efficient carbapenems.

Paragraph 0163; 0171, (2019/01/04)
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; wherein R1 and R2 both are hydrogen; or R1 is hydrogen and R2 is alkyl or aryl; or R1 is alkyl or aryl and R2 is hydrogen; or R1 and R2 both are alkyl or aryl (same or different groups); wherein alkyl group constitute C1-C6 alkyl or higher (both linear and branched) with or without heteroatoms; and aryl group constitute phenyl, substituted phenyl, heteraryl, arylalkyl and polynuclear aromatics. 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.
