Competing interests The authors declare that they have no competing interests. Authors’ contributions ETA Developed and validated the LC-MS/MS assay for the quantitative determination of TK900D and TK900E in mouse blood, and used the assay for PK-evaluation of your analytes; performed the data acquisition and interpretation with the benefits presented within the manuscript; compiled information and presented it in the form as it seems in the manuscript. MT synthesized the compounds and supplied us with in vitro activity data. LG assisted with the evaluation on the PK-properties employing PK-summit application. LW, KJS and JHW edited, revised and PKC Activator Purity & Documentation accepted the manuscript, that is a part of ETA’s PhD project. KC revised the manuscript. The final version with the manuscript has been study and accepted by each of the authors.
