Equisetin

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[1][2][3][4][5][6][7][8][9][10][11].
