Synthesis and SAR of 3,5-diamino-piperidine derivatives: novel antibacterial translation inhibitors as aminoglycoside mimetics.

abstract：:A novel series of potent DGAT-1 inhibitors was developed originating from the lactam-based clinical candidate PF-04620110. Incorporation of a dioxino[2,3-d]pyrimidine-based core afforded good alignment of pharmacophore features and resulted in improved passive permeability. Development of an efficient, homochiral synt...
