Equisetin
Based on 1 Customer Validation
Equisetin is an N-methylserine-derived acyl tetramic acid, quorum sensing inhibitor (QSI), herbicides and antibiotics. Equisetin specifically inhibits the anionic carriers of substrates in the inner mitochondrial membrane. Equisetin inhibits the activity of HIV-1 integrase, 11β-HSD1, and 2,4-dinitrophenol (Dnp)-stimulated ATPase (IC50 = ~8 nmol per mg of protein). Equisetin exhibits growth inhibition of bacteria, anti-inflammatory, amelioration of lipid-associated disorders, and cytotoxic effects.

Equisetin (50-300 μM, 6 h) inhibit the production of virulence factor, biofilm formation, and swarming motility of Pseudomonas aeruginosa PAO1[4].
Equisetin shows cytotoxicity against human CCRF-CEM cells assessed as growth inhibition by SRB assay, with a GI50 of 144 nM[7].
Equisetin (1-6 μg/mL, 0-6 h) removes Staphylococcus aureus from IEC-6 cells by enhancing host autophagy and inducing mitochondria-mediated ROS generation[8].
Equisetin (20 μM, 7 days) inhibits adiposity through AMPK-dependent regulation of brown adipocyte (BA) differentiation[9].
Equisetin (0.01-100 μM, pre-stimulates 12 h) attenuates lipid droplet accumulation and foam cell formation in macrophages[10].
Equisetin (0.01-10 μM) inhibits LPS and oxLDL-induced inflammatory responses in macrophages (RAW264.7 and BMDM)[10].
Equisetin (4 µg/mL) can potentiate Colistin (HY-113678) activity against multi-drug resistant gram-negative bacteria including Colistin -resistant strains[11].

Result:Increased the specific BA markers Prdm16 and the uncoupling protein Ucp1, the mitochondrial markers Pgc1α, and Tfam.
Increased AMPK and phosphorylated AMPK (pAMPK).
Equisetin (10 mg/kg, i.p., 6 h) shows significant anti-infective activity in a mouse model of Staphylococcus aureus ATCC 29213 infection[8].
Equisetin (5-20 mg/kg, p.o., every two days until 12 weeks) prevents atherosclerosis in mice by binding to and inhibiting the activity of STAT3[10].

-
Dosage:5, 20 mg/kg
-
Administration:Oral gavage (p.o.), every two days until 12 weeks

Result:Attenuated HFD-induced lipid area in the en face prepared aorta and aortic root.
Attenuated atherosclerotic lesion area (HFD versus HFD+5 mg/kg Equisetin: 31.71 versus 16.95; HFD versus HFD+20 mg/kg Equisetin: 31.71 versus 10.12).
Increased collagen content in the aortic plaques.
Increased α-SMA-positive areas in the plaques in aortic root.
