Abstract
A syntheses of three new muramyl dipeptide (MDP) analogues related to LK 423 as potential immunomodulators are presented. The dipeptide part of the lead compound was modified by introducing a phosphonamide isostere instead of the amide bond between Lalanine and D-glutamic acid (or [...] Read more.
A syntheses of three new muramyl dipeptide (MDP) analogues related to LK 423 as potential immunomodulators are presented. The dipeptide part of the lead compound was modified by introducing a phosphonamide isostere instead of the amide bond between Lalanine and D-glutamic acid (or D-isoglutamine), yielding new MDP analogues 5 and 9. Furthermore, the amide bond between L-Ala and D-Glu was replaced by a phosphonate isostere, giving peptidyl phosphonate 14. The scope and limitations of the synthetic strategies employed are discussed. Full article

Abstract
This work describes the synthesis of seven new platinum complexes having Nbenzyl 1,3-propanediamine derivatives as ligands. They were prepared by the reaction of K2[PtCl4] with the appropriate ligand in water. These complexes are analogs of cisplatin, and are potential antineoplastic agents. Full article
