6-Bromoisatin inhibited proliferation of HT29 cells at IC50 223 μM (0.05 mg/mL) and induced apoptosis without increasing caspase 3/7 activity. In vivo 6-bromoisatin (0.05 mg/g) was found to significantly enhance the apoptotic index (p ≤ 0.001) and reduced cell proliferation (p ≤ 0.01) in the distal colon.
| [Synthesis]
Step 2: N-(3-bromophenyl)-2-hydroxyiminoacetamide (55 g, 0.2272 mol) was added to concentrated sulfuric acid (275 mL) and the temperature was maintained at 50 °C. The temperature of the reaction system was then raised to 90 °C for 3 hours. Upon completion of the reaction, the reaction mixture was slowly poured into ice water and a yellow precipitate was precipitated. The precipitate was collected by filtration and dried to give 6-bromodihydroindole-2,3-dione as a yellow solid (50 g, 98% yield). The resulting product can be used directly in the subsequent reaction without further purification. | [Purification Methods]
6-Bromoisatin recrystallises from AcOH (yellow needles). It is a plant growth substance. IR in CHCl3 has 1320 and 3440cm-1. [Sadler J Org max Chem 21 169 1956, Beilstein 21 III/IV 5012.] | [References]
