biological activity | Thiomyristoyl (TM) is a potent, specific SIRT2 inhibitor with an IC50 of 28 nM. It inhibits SIRT1 with an IC50 value of 98 μm, whereas it has no inhibitory effect on SIRT3 at concentrations up to 200 μm. |

in vitro study | Thiomyristoyl(TM) is a highly selective SIRT2 inhibitor. It does not effectively inhibit SIRT3, SIRT5, SIRT6 or SIRT7. In vitro, it can significantly inhibit cell activity, and its cytotoxicity has a certain selectivity for cancer cells. TM reduces tumor protein levels by c-Myc in cancer cells. In different cell lines, the ability of TM to reduce abundance by c-Myc correlates with the cell line's sensitivity to TM. |
in vivo study | the anti-cancer effect of TM is associated with its ability to reduce levels by c-Myc. The effect of TM on non-cancer cell lines and tumor-free mice is very limited. |
