It has a molecular formula of C16H12O5 and a molecular weight of 284.26 g/mol. 3'-Methoxydaidzein is a phytoestrogen with estrogenic activity. It exhibits antioxidant, anti-inflammatory, and anticancer properties. The compound is a sodium channel inhibitor, inhibiting subtypes NaV1.7, NaV1.8, and NaV1.3 with IC50 values of 181 nM, 397 nM, and 505 nM, respectively. It also has antiplatelet aggregation activity.
Biological Activity I Assay Protocols (From Reference)
Targets
Nav1.3 505 nM (IC50); Nav1.7 181 nM (IC50); Nav1.8 397 nM (IC50)
The primary targets of 3'-Methoxydaidzein include voltage-gated sodium channels (NaV1.7, NaV1.8, and NaV1.3). It inhibits NaV1.7 with an IC50 of 181 nM, NaV1.8 with an IC50 of 397 nM, and NaV1.3 with an IC50 of 505 nM. By inhibiting these sodium channels, 3'-Methoxydaidzein may modulate pain signaling and neuronal excitability. The compound also exhibits antiplatelet aggregation activity, appearing to be specific against collagen-induced platelet aggregation with IC50 values of 12.3 and 61.5 µM. Its estrogenic activity classifies it as a phytoestrogen.
ln Vitro
3'-Methoxydaidzein has been reported in Maackia amurensis, Dalbergia louvelii, and other organisms. 7,4'-dihydroxy-3'-methoxyisoflavone is a member of the class of 7-hydroxyisoflavones that is 7,4'-dihydroxyisoflavone substituted by a methoxy group at position 3'. It is isolated from the heart woods of Maackia amurensis subsp buergeri and Dalbergia louveli and exhibits antiplasmodial ativity. It has a role as a metabolite and an antiplasmodial drug. It is a methoxyisoflavone and a member of 7-hydroxyisoflavones.
In vitro, 3'-Methoxydaidzein inhibits sodium channel subtypes NaV1.7, NaV1.8, and NaV1.3 with IC50 values of 181 nM, 397 nM, and 505 nM, respectively. The compound also exhibits antiplatelet aggregation activity, with IC50 values of 12.3 and 61.5 µM against collagen-induced platelet aggregation. It has antioxidant, anti-inflammatory, and anticancer properties. 3'-Methoxydaidzein is a natural isoflavone with a molecular weight of 284.26 g/mol and is a phytoestrogen.
ln Vivo
Isoflavones are widely consumed by people around the world in the form of soy products, dietary supplements and drugs. Many isoflavones or related crude extracts have been reported to exert pain-relief activities, but the mechanism remains unclear. Voltage-gated sodium channels (VGSCs) play important roles in excitability of pain sensing neurons and many of them are important nociceptors. Here, we report that several isoflavones including 3'-methoxydaidzein (3MOD), genistein (GEN) and daidzein (DAI) show abilities to block VGSCs and thus to attenuate chemicals and heat induced acute pain or chronic constriction injury (CCI) induced pain hypersensitivity in mice. Especially, 3MOD shows strong analgesic potential without inducing addiction through inhibiting subtypes NaV1.7, NaV1.8 and NaV1.3 with the IC50 of 181 ± 14, 397 ± 26, and 505 ± 46 nmol·L-1, respectively, providing a promising compound or parent structure for the treatment of pain pathologies. This study reveals a pain-alleviating mechanism of dietary isoflavones and may provide a convenient avenue to alleviate pain.[1]
In vivo, 3'-Methoxydaidzein has potential therapeutic applications due to its antioxidant, anti-inflammatory, anticancer, and antiplatelet activities. As a phytoestrogen, it may have effects on hormone-related conditions. Its inhibition of sodium channels suggests potential applications in pain research. However, detailed in vivo efficacy and safety data are not extensively reported in the available literature, and its use is primarily limited to preclinical research settings. Further studies are needed to fully characterize its in vivo effects and therapeutic potential.
Enzyme Assay
In vitro assays for 3'-Methoxydaidzein typically involve measuring its inhibition of sodium channel activity using electrophysiological techniques such as patch-clamp recording in cell lines expressing recombinant NaV1.7, NaV1.8, or NaV1.3 channels. The compound is applied to the cells at varying concentrations (typically 1-1000 nM), and the resulting inhibition of sodium current is measured. The IC50 values of 181 nM, 397 nM, and 505 nM for NaV1.7, NaV1.8, and NaV1.3, respectively, are determined by fitting concentration-response curves. Antiplatelet aggregation activity is assessed using platelet aggregation assays with collagen as the inducer.
Cell Assay
Cellular assays for 3'-Methoxydaidzein typically use cell lines expressing recombinant sodium channels, such as HEK293 or CHO cells, for electrophysiological studies. The compound is applied to the cells, and its effects on channel activity are assessed using patch-clamp recording. Fluorescent-based membrane potential assays using voltage-sensitive dyes can also be used for higher-throughput screening of channel activity. Antiplatelet assays are performed using platelet-rich plasma, where the compound's ability to inhibit collagen-induced platelet aggregation is measured.
Animal Protocol
In vivo animal studies for 3'-Methoxydaidzein would likely involve the administration of the compound to rodent models to study its effects on pain, inflammation, cancer, or platelet aggregation. The compound could be administered via oral gavage or intraperitoneal injection. Endpoints would depend on the specific research question and could include pain-related behaviors, tumor growth, inflammatory markers, or platelet function. However, specific in vivo study protocols for 3'-Methoxydaidzein are not detailed in the available literature.
ADME/Pharmacokinetics
Pharmacokinetic data for 3'-Methoxydaidzein are not extensively reported in the available literature. The compound has a molecular weight of 284.26 g/mol and is a natural isoflavone. As a phytoestrogen, its pharmacokinetic properties would be expected to be similar to other isoflavones, with good oral bioavailability and metabolism by gut microbiota and hepatic enzymes. Detailed parameters such as half-life, volume of distribution, and bioavailability are not publicly available and would need to be determined experimentally.
Toxicity/Toxicokinetics
There is no specific toxicity data reported for 3'-Methoxydaidzein in the available literature. As a natural product and research chemical, it is generally considered safe at research doses. However, standard safety precautions should be followed when handling the compound. Toxicity studies, including acute and sub-chronic dosing in animal models, would be required if the compound were to be developed further for therapeutic applications. The compound is not approved for human therapeutic use.
