| Cell experiment [1]: | |
|
Cell lines |
MDA-MB-231 cells |
|
Preparation method |
The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
|
Reaction Conditions |
80, 250, 500 nM; 1 d to 4 d |
|
Applications |
In MDA-MB-231 cells, in a concentration-dependent manner, exposure to UNC0638 for 48 h reduced H3K9me2 levels with an IC50 value of 81 ± 9 nM. Cellular levels of H3K9me2 were progressively reduced from 1 d to 4 d exposure to UNC0638 at the concentrations of 80 nM (IC50), 250 nM (IC90) and 500 nM (2 × IC90). The reductions of H3K9me2 levels with 250 nM and 500 nM treatments after 4 d were equal or very close to that of G9a and GLP knockdown cells. The effects of UNC0638 were long-lasting. In cells with 2 d exposure to UNC0638, levels of H3K9me2 remained low after washout of compound followed by 2 d incubation without the inhibitor. |

Dosage form |
5 mg/kg; i.p. |
|
Applications |
UNC0638 was not suitable for animal studies due to its poor pharmacokinetic properties. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

UNC0638 is a potent and selective inhibitor of G9a and GLP with IC50 values of < 15 nM and 19 ± 1 nM, respectively [1].
GLP forms a heterodimer with G9a. Both G9a and GLP can mono- and dimethylate histone H3 Lys9 (H3K9), and dimethylate Lys373 of p53 and hence inactivate the transcriptional activity of p53 [1].
UNC0638 showed balanced physicochemical properties and potency aiding cell penetration in vitro, had high potency in cellular assays. It was much less toxic than BIX01294 to cells. In MDA-MB-231 cells, in a concentration-dependent manner, exposure to UNC0638 for 48 h reduced H3K9me2 levels with an IC50 value of 81 ± 9 nM (n= 3), which showed considerably higher potency than BIX01294 (IC50= 500 ± 43 nM (n= 3)). In reducing H3K9me2 levels, UNC0638 was of greater maximum effect than BIX01294. This effect is close, but not equal, to the effect on the double knockdown of G9a and GLP via shRNA [1].
In 6-week-old male athymic nude mice subcutaneously inoculated with BON cells, UNC0638 decreased H3K9me2 level [2]. In organotypic cochlear cultures, rapid increase of H3K9me2 upon the damage of hair cells was observed. Both ex vivo and in vivo, UNC0638 effectively prevented aminoglycosides-induced hair cell damage [3].
