4-Methoxybenzyl alcohol
Based on 1 Customer Validation
4-Methoxybenzyl alcohol (P-Methoxy-benzyl alcoho; (4-Methoxyphenyl) methanol) is a naturally derived volatile aromatic compound. 4-Methoxybenzyl alcohol upregulates the phosphorylation level of PI3K/Akt pathway proteins, downregulates the expression of pro-inflammatory factors, increases the content of tight junction proteins occludin and claudin-5, and alleviates structural damage to the blood-brain barrier. 4-Methoxybenzyl alcohol improves the decrease in viability and NO level of cerebral microvascular endothelial cells induced by oxygen-glucose deprivation/reperfusion, and reduces the release of lactate dehydrogenase. 4-Methoxybenzyl alcohol serves as a substrate in the two-phase persulfate-mediated electro-oxidation system, where it is directionally oxidized to p-anisaldehyde. 4-Methoxybenzyl alcohol acts as a substrate for wild-type fungal aryl alcohol oxidase. 4-Methoxybenzyl alcohol can be used in studies related to ischemic stroke, as well as in research across various fields such as chemical synthesis, including the synthesis of fragrances and flavorings.

4-Methoxybenzyl alcohol (4-MA) (25-800 µM; 36 h) shows no cytotoxicity to bEnd.3 cells at concentrations up to 800 µM, and significantly increases the survival rate of bEnd.3 cells injured by OGD/Rep, with the strongest effect observed at the concentration of 200 µM[1].
4-Methoxybenzyl alcohol (50-200 µM; 36 h post-OGD/Rep) reduces LDH release and increases NO levels in bEnd.3 cells injured by OGD/Rep[1].
4-Methoxybenzyl alcohol (200 µM; 36 h post-OGD/Rep) upregulates the expression of tight junction proteins occludin and claudin-5 in OGD/Rep-injured bEnd.3 cells, and activates the PI3K/AKT signaling pathway, as evidenced by increased phosphorylation levels of AKT and eNOS[1].
4-Methoxybenzyl alcohol (200 µM; 36 h post-OGD/Rep) reduces the levels of pro-inflammatory cytokines TNF-α, IL-1β and IL-6 in OGD/Rep-injured bEnd.3 cells[1].
4-Methoxybenzyl alcohol can be oxidized by wild-type and mutant AAO from Pleurotus eryngii, among which the I500M mutant exhibits the highest catalytic efficiency[2].
4-Methoxybenzyl alcohol serves as a substrate in the two-phase persulfate-mediated electro-oxidation system, and undergoes directional oxidation to p-anisaldehyde[3].
