3-Methoxycatechol
Based on 1 Customer Validation
3-Methoxycatechol is a catechol derivative with endothelium-dependent vasodilatory and antihypertensive activities. 3-Methoxycatechol activates GPR35, triggering dynamic mass redistribution and β-arrestin translocation. 3-Methoxycatechol inhibits tau self-interaction and scavenges free radicals such as DPPH. 3-Methoxycatechol combined with NaNO2 enhances forestomach proliferative lesions and papilloma formation, reduces glandular stomach lesions, and promotes esophageal lesion development. 3-Methoxycatechol can be used for research related to hypertension and papilloma.

In Vitro
3-Methoxycatechol (100 nM-100 μM) effectively relaxes resistance mesenteric arteries in male Wistar rats, with an EC50 of 12.5 μM[1].
3-Methoxycatechol (10 nM-100 μM) does not induce vasodilation of porcine coronary artery rings[1].
3-Methoxycatechol (100 nM-100 μM) exerts a vasodilatory effect in male Wistar rat aortic rings that is mildly endothelium-dependent[1].
3-Methoxycatechol enhances cGMP- and cAMP-mediated vasodilation in aortic rings of male Wistar rats, but does not act directly on sGC or PKG[1].
3-Methoxycatechol-induced vasodilation of aortic rings in male Wistar rats involves KV channels, especially KV7 channels, whereas BKCa, KATP, and KIR channels are not involved[1].
3-Methoxycatechol does not inhibit L-type Ca2+ channels in aortic rings of male Wistar rats, but its vasodilatory effect is attenuated when SERCA is inhibited[1].
3-Methoxycatechol exhibits potent DPPH radical scavenging activity, with an EC50 of 0.16 mol AH/mol DPPH and an AE of 48 x 103 mol DPPH/(mol AH x t)[5].
3-Methoxycatechol (10 µM; 2-24 h) significantly disrupts microtubule stability in HuH-7 cells[2].
3-Methoxycatechol molecular docking results support its mechanism of action through activation of KV7.4 channels[3].
3-Methoxycatechol (1 h) acts as a GPR35 agonist in native HT-29 cells, eliciting dose-dependent DMR with an EC50 of 147 μM and a maximum DMR signal of 219 pm[4].
3-methoxycatechol-induced DMR in HT-29 cells is biphasically inhibited by mL-145 (HY-107536)[4].
3-Methoxycatechol (5 h) is active in the Tango β-arrestin translocation assay in U2OS-GPR35-bla cells, with an EC50 of 80.7 μM and an efficacy of 41% of the maximal response to zaprinast[4].
3-Methoxycatechol (1 mM) exhibits a low oxidation potential of 0.200 V vs. Ag/AgCl at pH 7.02, confirming its high electron-donating capacity and antioxidant effect[5].

In Vivo
3-methoxycatechol (3-methoxycatechol; mixed into feed; daily; approximately 24 weeks) combined with 0.3% NaNO2 most significantly reduces GST-P-positive liver foci and inhibits the development of glandular stomach lesions, while strongly stimulating forestomach hyperplasia[7].
3-methoxycatechol (2%; mixed into feed; daily; until week 28) induces forestomach hyperplasia and glandular stomach adenomas in rats without initiation, but does not promote forestomach carcinogenesis[7].
3-methoxycatechol (2%; mixed into feed; daily; until week 28), in combination with NaNO2, strongly stimulates forestomach hyperplasia and papilloma development in non-initiated rats, while significantly reducing the incidence of glandular stomach lesions[7].
