摘要:

利用细胞膜色谱/超高相液相色谱-质谱(CMC/UPLC-MS)方法对中药饮片鹿角胶中的有效成分进行筛选,结合Maxquant软件、Perseus软件以及Uniprot数据库对所得谱图进行数据分析,使用Protein Data Bank对分析结果进行结构鉴定,同时采用生物信息学平台对这些肽段的生物活性、不良反应、相对分子质量、等电点、不稳定指数等基本分子特性进行预测。鉴定肽段活性概率为0.09,无毒,无溶血性,有致敏性,相对分子质量为1 541.68,肽链长度为14,亲水性为良好,等电点值为3.92,不稳定性指数为34.39。该方法为快速筛选鉴定具有药理作用的多肽和蛋白质等活性成分提供了一条可行的研究思路。

Abstract:

Cell membrane chromatography/ultrahigh-phase liquid chromatography-mass spectrometry (CMC/UPLC-MS) was used to screen the active ingredients, i.e., peptides, in the traditional Chinese medicine tablet Cervi cornus Colla, and the obtained spectra were analyzed using Maxquant software, Perseus software, and Uniprot database. Structures of these peptides were identified using Protein Data Bank, and their molecular properties such as their biological activity, adverse reactions, relative molecular mass, isoelectric point, and stability index were predicted using a bioinformatics platform. With an activity probability of 0.09, the peptides were identified as nontoxic, nonhemolytic, sensitizing, and highly hydrophilic, with a relative molecular mass of 1 541.68, a peptide chain length of 14, an isoelectric point of 3.92, and an instability index of 34.39.This method provides a feasible research approach for rapidly screening and identifying active ingredients(e.g., peptides and proteins) that exhibit pharmacological effects.
