Odor: characteristic
Use: Growth-inhibitory activity of the compound against Strep. mutans of both clinical and type strain cultures was evaluated. The anti-Strep. mutans activity of the guaijaverin was found to be bacteriostatic, both heat and acid stable and alkali labile with the minimum inhibitory concentration (MIC) of 4 mg ml-1 for MTCC 1943 and 2 mg ml-1 for CLSM 001. The sub-MIC concentrations (0.0078-2 mg•ml-1) of the guaijaverin were evaluated for its cariogenic properties such as acid production, cell-surface hydrophobicity, sucrose-dependent adherence to glass surface and sucrose-induced aggregation of Strep. mutans.
