Biological Activity
G43 (16 h) inhibits more than 85% of S. mutans biofilm at 12.5 μM[1].
G43 (25 μM, 24 h) reduces the glucan production by the glucosyltransferase (Gtfs), and consistently inhibits the activity of both GtfB and GtfC with 80% inhibition of both enzymes[1].
G43 (up to 25 μM, 24 h) shows no significant difference on expression of gtfs (gtfB, gtfC and gtfD) in S. mutans. UA159 cells[1].
G43 (50 μM, 24-48 h) reduces the biofilm formation by decreasing the production of Water-insoluble extracellular polysaccharide in wild-type S. mutans[2].
