目的:利用理論對(duì)接方法對(duì)查爾酮類衍生物的可能活性作用進(jìn)行虛擬評(píng)價(jià)。方法:選取12個(gè)查爾酮類衍生物，收集現(xiàn)有常見靶標(biāo)的晶體結(jié)構(gòu)，利用Schr?dinger軟件進(jìn)行計(jì)算，估算測(cè)試分子的非特異性對(duì)接得分，以分級(jí)標(biāo)準(zhǔn)評(píng)價(jià)選擇性。結(jié)果:查爾酮類衍生物的選擇性靶標(biāo)涉及癌癥、糖脂代謝紊亂、心血管疾病、炎癥等。結(jié)論:虛擬評(píng)價(jià)發(fā)現(xiàn)的查爾酮類衍生物的活性作用與文獻(xiàn)報(bào)道相符，該技術(shù)具有較大的實(shí)用性，本研究為利用理論手段研究中藥成分的作用機(jī)制進(jìn)行了有益的嘗試。

Objective: To evaluate the potential biological activities of chalcones by theoretical docking calculation. Methods: Twelve chalcones derivatives were selected as the ligands. Crystal structures of proteins related to common diseases were used as the receptors for calculation. The Schr?dinger software package was employed to dock the molecular into the targets. The grading standard was used to analyze the docking results. Results: Selective targets of chalcones were related to cancer, lipid metabolic disturbance, cardiovascular disease, inflammation, and so on. Conclusion: The biological activities of chalcones founded through virtual evaluation are in accordance with the reports and this technique has great practicality. The study is a meaningful attempt to discover the mechanism of active component in Chinese material medica with a theoretical method.
