Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC50/Ki
SIRT2 [1]
(Cell-free assay)
28 nM
In vitro
Thiomyristoyl(TM) is a highly selective SIRT2 inhibitor. It cannot efficiently inhibit SIRT3, SIRT5, SIRT6, or SIRT7. In vitro, it shows great inhibition of cell viability and its cytotoxicity is relatively selective toward cancer cells. TM decreases c-Myc oncoprotein level in cancer cells, the ability of TM to decrease c-Myc abundance in different cell lines correlates with the sensitivity of the cell lines to TM[1].
In vivo
The anticancer effect of TM correlates with its ability to decrease c-Myc level. TM has limited effects on non-cancerous cells and tumor-free mice[1].
