In vitro study | The slight bias of 3-MA to Vps34 may be due to the fact that a specific hydrophobic ring structure in Vps34 can surround the 3-methyl group of 3-MA. It has been reported that 3-MA can cause cell death for both normal cultured and starvation treated cancer cells. 3-MA may also inhibit cell migration and invasion without inhibiting autophagy, suggesting that 3-MA has other biological functions besides inhibiting autophagy. 3-MA can cause caspase-dependent cell death, a function that has nothing to do with its inhibition of autophagy. Treatment of glucose-starved Hela cells with 5mm 3-MA reduced the proportion of gfp-lc3-positive cells to 23%. LC3-I levels rose and LC3-II levels fell within 12 to 48 hours of 3-MA treatment. The conversion of LC3-I to LC3-II was inhibited by 3-MA. Treatment of HeLa cells with 2.5 mM or 5 mM 3-MA for one day did not affect cell viability, whereas treatment with 10 mM 3-MA for one day caused a 25.0 percent decrease in cell viability. Treatment of cells with 2.5, 5, or 10 mM 3-MA for two days decreased cell viability by 11.5, 38.0, and 79.4 percent, respectively. 3-MA The effect of reducing cell viability has a time-and dose-dependent character. 3-MA significantly shortened the pre-metaphase blocking time induced by nocodazole. 3-MA inhibits su11274-induced cell death by inhibiting autophagy. Prolonged 3-MA treatment time (up to 9 H) in wild-type MEF cells clearly resulted in LC3 I to II conversion. Extending the 3-MA treatment time significantly increased GFP-LC3 aggregation whereas wortmannin did not have this feature. 3-MA-mediated LC3 turnover and free GFP release are ATG7 dependent. 3-ma treatment resulted in a significant increase in p62 protein levels. Even in Atg5 −/− MEF cells, 3-MA increased p62 levels, as in cells with DOX-mediated ATG5 deletion. 3-MA inhibits type I and Type III PI3K in different ways. 3-MA induced LC3 I to LC3 II in Tsc2 −/− cells compared with wild-type cells The conversion process has dropped significantly. 3-MA disrupts the antagonistic autophagy function of mTOR complex 1. |
In vivo study | 3-Methyladenine (3-MA) can block autophagy by acting on phosphoinositide 3-phosphate kinase (PI3K), the activity of PI3K is necessary for the nucleation and assembly of the early membrane pool of autophagosome formation. 3-MA did not change the extent of bleeding compared to the SAH-treated group. Neurological symptoms were significantly aggravated after pretreatment with 3-ma compared with the SAH control group. 3-MA treatment reduced autophagy. In contrast, expression of cleaved caspases was significantly up-regulated in the SAH 3-MA group, consistent with the SAH control group, the number of in situ end-labeled positive cells in the right cerebral cortex was significantly increased in the SAH 3-MA group. |

biological activity | 3-Methyladenine (3-MA, NSC 66389) is a selective PI3K inhibitor that acts on Vps34 and PI3Kγ, and IC50 in HeLa cells is 25 μM and 60 μM respectively; Permanent inhibition of type I PI3K, but the inhibition of type III PI3K is transient, which also blocks the formation of autophagosomes. 3-Methyladenine (3-MA) can be successfully applied to inhibit mitochondrial autophagy. Now ready for use (heating to help dissolve). |
