Afzelin (Synonyms: Kaempferol-3-O-rhamnoside) is a flavonol glycoside that has anti-inflammatory, anti-oxidative stress response, anti-apoptotic, and anti-cardiac cytotoxic effects. AfzelinIt can reduce mitochondrial damage, enhance mitochondrial biosynthesis, and reduce mitochondria-related proteins. Parkinand PTENinduced putative kinase 1 (putative kinase 1)s level. AfzelinCan be improved D-galactosamine(GalN)/LPSSurvival rate of mice treated with doxorubicin prophylaxis Induced cardiotoxicity and scopolamine -induced neurological injury. AfzelinAlso inhibits asthma and allergies caused by ovalbumin. | [Uses]
Kaempferol 3-O-α-L-Rhamnoside is found in Cornus macrophylla and has shown to have antibacterial activity against Pseudomonas aeruginosa, a leading cause of illness in immunocompromised individuals. | [Definition]
ChEBI: A glycosyloxyflavone that is kaempferol attached to a alpha-L-rhamnosyl residue at position 3 via a glycosidic linkage. | [in vivo]
Afzelin (5, 10 mg/kg/day; po; 20 days) attenuates DOX toxicity-induced cardiac injury in a concentration-dependent manner. Afzelin exerts cardioprotective effects by upregulating p-AMP-activated protein kinase α (AMPKα) and Sirtuin1 (SIRT1) levels[2].
Afzelin (0.1-10 mg/kg/day; po; for 5 days) reduces the asthma phenotype by downregulating the GATA-binding protein 3 transcription factor (GATA3) in mouse models of asthma. Afzelin inhibits GATA3 and reduces Th2 cytokines, while GATA3 is the main regulator of Th2 cytokine differentiation and production[3].
Afzelin (100 ng/μL vis icv; 3 times a week for 1 month) ameliorates synaptic plasticity and cognitive/memory behaviors in mice given Scopolamine (HY-N0296)[4].
| Animal Model: | C57BL/6 Mouse[2] | | Dosage: | 5 mg/kg/day, 10 mg/kg/day | | Administration: | Oral gavage for 20 days, while C57BL/6 mouse were treated with 4 mg/kg/d (ip, injected at day 1, 7, 14) DXO for 3 doses. | | Result: | Attenuated DOX-induced cardiac damage and reduced serum levels of alanine aminotransferase and pro-inflammatory cytokines.
Also upregulated the expression of p-AMP-activated protein kinase α (AMPKα) and Sirtuin1 (SIRT1).
|
| Animal Model: | Asthma murine model sensitized by ovalbumin (OVA)[3] | | Dosage: | 0.1, 1 and 10 mg/kg | | Administration: | PO; once daily from day 19 to day 23 | | Result: | Suppressed eosinophil infiltration, allergic airway inflammation, airway hyperresponsiveness, OVA-specific IgE and Th2 cytokine secretion.
|
| Animal Model: | Scopolamine induced mouse model[4] | | Dosage: | 100 ng/μL | | Administration: | ICV, administered into the third ventricle of the hypothalamus; 3 time per week for 1 month | | Result: | Resulted the restoration of the cholinergic systems and molecular signal transduction via CREB-BDNF pathways.
Led to improved neurocognitive and neuroprotective effects on synaptic plasticity and behaviors partly through the increase in CREB-BDNF signaling.
