Abstract:
:A scaffold hopping strategy was successfully applied in discovering 2-aminooxazole amides as potent DGAT1 inhibitors for the treatment of dyslipidemia. Further optimization in potency and PK properties resulted in a lead series with oral in vivo efficacy in a mouse postprandial triglyceridemia (PPTG) assay.
