RESUMO
Based on the anticancer mechanism of biological alkylating agent, we designed and synthesized two alpha pinene derivatives:(1R,5S)-(6,6-dimethylbicyclo[3,1,1]hept-2-en-2-yl)methyl benzenesulfonate and (1R,5S)-(6,6-dimethylbicyclo[3,1,1]hept-2-en-2-yl)methyl 4-methylbenzenesulfonate, of which structures were confirmed by ¹H-NMR, HPLC and MS date. These two compounds showed a good inhibition of tumor cells' proliferation. Further, the computer siuulation of molecular docking and metabolic kinetics indicated that these two copounds may have stable molecular complexation with protein CDK2, which closely related to the cell cycle.
RESUMO
<p><b>OBJECTIVE</b>To extract and separate toxic components from Phytolaccae Radix, and to comare the changes in toxicity of Phytolaccae Radix before and after being processed with vinegar.</p><p><b>METHOD</b>The mucous membrane irritation response, mouse peritoneal inflammation model and in vitro macrophages release NO model were applied to compared the changes in inflammatory toxicity of toxic components from Phytolaccae Radix before and after being processed with vinegar.</p><p><b>RESULT</b>Toxic components of Phytolacca Radix had significant inflammatory toxicity, which could cause conjunctival edema in rabbits, and increase of PGE2 and macrophages release NO content in peritoneal exudate in mice. After being processed with vinegar, they showed reduced irritation, which resulted in decrease of PGE2 and macrophages release NO content in peritoneal exudate in mice.</p><p><b>CONCLUSION</b>After being processed with vinegar, the toxicity of toxic components from Phytolacca Radix decreased obviously.</p>
