@Mauritio its an aldehyde so doesnt sound like a healthy compound / pro metabolic outside of specific use nah (probably best not to take generally outside of cancer) so its one of those things that has an outweighing effect on cancer cells, the anti-cancer dose didnt show toxicity though so i guess healthy cells can deal with that amount well enough but probably some extra burden

apparently low amounts can stimulate cancer growth but higher amounts triggers the apoptosis process (thats normally lacking because of damage making it inefficient, and pH change, needs to be more acidic inside the tissue for apoptosis to happen optimally, cancers are acidic nearby but higher end pH inside - maybe methylglyoxal accumulation makes the tumor more acidic?)

Also it has two carbonyl groups , koch and reinstorff back in the day thought these can be used to take out things with strong bonds that are sticking around blocking mitochondria respiration and enable healthy processes again. maybe @dapose has more to to say on that

Following Glo1 inhibition, cancer cells switch from glycolysis to tricarboxylic acid (TCA) cycle to avoid apoptosis induced by MGO accumulation.

for some reason cancer cells are more sensitive to MGO overload than normal ones even though they have higher glutathione (which sounds to me like the effect is less about damage and more about re-enabling apoptosis unless for some reason they accumulate extreme amounts) https://www.science.org/doi/10.1126/science.160.3832.1140.a
