| Application | Arsenic Iodide is an orange-red shiny crystal (acetone). Toxic! The melting point is 146 ℃, the boiling point is 403 ℃, and the relative density is 4.3918. Arsenic Iodide slightly soluble in water, soluble in ethanol, ether, carbon disulfide. Preparation Method: As2O3 is dissolved in concentrated hydrochloric acid, and then the aqueous solution of potassium iodide is added, filtered and dried. Purposes: used as analytical reagents for the analysis of chemical, toxic and pharmaceutical drugs. arsenic iodide can be used as an analytical reagent for the analysis of chemicals, poisons and pharmaceuticals. |
| activity Study | Wang Ming et al. discussed a new Arsenic Iodide complex Arsenic Iodide-thiourea (AsI3-Tu) effects on proliferation and survivin gene expression of leukemia HL-60 cells. Methods: HL-60 cells were treated with different concentrations of arsenic iodide-thiourea, cell proliferation activity was detected by MTT colorimetric method, cell apoptosis was observed by in situ end labeling (TUNEL) method, RT-PCR semi quantitative detection of sur-vivin mRNA expression in cells. Results: ①AsI3-Tu of each experimental group could inhibit the proliferation of HL-60 cells, which was related to the time and dose. (2) TUNEL method was used to observe the apoptosis, and the number of apoptotic cells in AsI3-Tu concentration groups was significantly increased. ③The expression level of survivin mRNA was decreased in AsI3-Tu groups, and the expression level was negatively correlated with the dose of AsI3-Tu. Conclusion: AsI3-Tu can effectively inhibit the proliferation of leukemia cell line HL-60 and induce its apoptosis. The mechanism may be related to the inhibition of survivin gene expression in HL-60 cells. |
