Screening of Antitumor Active Components and Key Targets of Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma Based on PI3K/Akt Pathway
借助Traditional Chinese Medicine Systems Pharmacology(TCSMP)平台构建附子-半夏小分子配体库;基于分子对接(SYBYL2.1,Tripos)将附子-半夏小分子与磷脂酰肌醇-3-激酶(phosphatidylinositol 3-kinase,PI3K)/蛋白激酶B(protein kinase B,Akt)信号通路中的关键靶标蛋白进行能量匹配;借助Cytoscape 3.5.1构建附子-半夏活性成分-靶标网络模型;基于Ligplot计算小分子与靶标蛋白形成的氢键、疏水作用和结构比对;附子-半夏抗肿瘤活性成分的理化性质基于SwissADME和admetSAR进行预测。
Screen out the antitumor constituents of Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma base on system pharmacology with chemical constituents of Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma as study objects
in order to provide the theoretical basis for the development of antitumor and nontoxic activities of Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma.
Method:
2
The small molecule ligand library of Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma was built based on Traditional Chinese Medicine Systems Pharmacology(TCMSP)
energy of Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma was matched with the key protein targets of phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signal pathway by molecular docking (SYBYL2.1
Tripos)
the Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma-targets network model was established based on Cytoscape 3.5.1
and the physicochemical properties of the antitumor activity in Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma were predicted by using SwissADME and admetSAR.
Result:
2
There were 25 small molecule constituents of Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma. Through the energy match
key antitumor constituents of Pinelliae Rhizoma were gondoic acid
10
13-eicosadienoic
baicalin
12
13-epoxy-9-hydroxynonadeca-7
10-dienoic acid. Key antitumor constituents of Aconiti Lateralis Radix Praeparata were deltoin
phosphatase and tensin homolog deleted on chromosome ten (PTEN)
phosphoinositide dependent protein kinase 1 (PDK1) were key antitumor targets of Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma. There were 8 key antitumor constituents of Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma
which had a low CYP450 inhibition and basically followed the Lipinski rule.
Conclusion:
2
Antitumor nontoxic constituents of Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma and key targets are screened out from the molecular level
which provides the new ideas for the effective use of nontoxic traditional Chinese medicine(TCM) and breaks the restrictions in using nontoxic TCM.
