| Description | Saccharin 1-methylimidazole (SMI) is a general-purpose activator used for DNA and RNA synthesis.  | 
| In vitro | Exposure to various concentrations of distinct promoters, including phenobarbital and the calcium and sodium salts of saccharin (22, 23, 25, 29, 38), induces calcium-deprived T51B cells to commence DNA synthesis as swiftly and as efficiently, or nearly as efficiently, as when the extracellular calcium concentration is increased to 1.25 mM.  |
