Regarding the doses used in vivo and mode of delivery, one needs to think about the goal of the experiment. The authors observed high inhibition of triglyceride synthesis in mice at a low dose of 0.088 mg/kg mostly due to DGAT1 inhibition in the GI tract where the compound’s concentration is likely to be significantly higher during drug absorption following oral dosing. Studying compound effect a few hours (4 and 15 selected by the authors) after dosing or using a parenteral route of administration are ways to evaluate systemic DGAT1 inhibition without the effect on enterocytes during compound absorption.

GSK2973980A has an acceptable in-vitro profile against its primary target and the off-targets that have been explored. There remains the possibility of in-vivo effects (desired efficacy and safety/toxicity) are due to poly-pharmacology, therefore it is suggested that additional data is generated. This could include profiling of GSK2973980A against a panel of protein targets from a variety of classes.
