3'-Methoxyflavonol exhibits a diverse range of bioactivities. It has shown vasorelaxant activity in Sprague-Dawley rat thoracic aorta under both endothelium-dependent and endothelium-independent conditions, with various EC50 values indicating its potency. Additionally, it demonstrates antioxidant properties by reducing superoxide levels and DPPH scavenging activities within the same experimental model. 3'-Methoxyflavonol is also potent as an inhibitor in various biochemical assays, targeting interactions such as Menin-MLL, human Jumonji Domain-containing 2E (JMJD2E), and Thyroid Stimulating Hormone Receptor, among others. It inhibits multiple enzymes including Tyrosyl-DNA Phosphodiesterase (TDP1), Cytochrome P450 isoforms (2C19, 2D6, 2C9, 3A4), 12-human lipoxygenase (12-hLO), and 15-Hydroxyprostaglandin Dehydrogenase (HPGD), and modulates cellular functions like ERK signaling pathway and Tau fibril formation. Furthermore, it shows antiviral properties against Lassa Virus and Marburg Virus, and anti-parasitic activity against Trypanosoma brucei brucei Lister 427, with an EC50 of 2320.0 nM and a selectivity index of 4.0. In prostate cancer models, it inhibits prostate-specific antigen (PSA) and androgen receptor (AR) expression in human 22Rv1 cells, showing antiproliferative activity with an IC50 of 5300.0 nM. Moreover, it exhibits cytotoxic activity against human HCT116 cells, with notable viability reduction at 15 uM after 48 hours. Overall, 3'-Methoxyflavonol demonstrates significant potential due to its broad bioactivity spectrum including vascular, antioxidant, enzymatic inhibition, antiviral, antiproliferative, and antitrypanosomal properties..
