摘要: 探讨鸡蛋花不同提取部位(水提取部、正丁醇部、石油醚部、乙酸乙酯部)对肥大细胞脱颗粒反应的抑制效果,运用网络药理学探讨鸡蛋花有效活性成分改善I型超敏反应的作用机制。使用吐温80构建RBL-2H3细胞脱颗粒模型,评估鸡蛋花的抗瘙痒药效。预测鸡蛋花治疗超敏反应的靶标和通路,使用分子对接方式验证鸡蛋花有效成分与关键靶标的结合能力。结果表明鸡蛋花的乙酸乙酯部提取物对超敏反应的抗瘙痒机制有明显的效用。其中鸡蛋花苷类成分与黄酮类成分在抗瘙痒,改善超敏反应的机制可能与D(2)多巴胺受体、P2Y嘌呤受体2、5-羟色胺受体2A、P2Y-嘌呤受体1、毒蕈碱乙酰胆碱受体M1、5-羟胺受体2C、毒物学乙酰胆碱受体M、α-1D肾上腺素能受体、α-1A肾上腺素能受体、P2Y-嘌呤受体1等蛋白调节相关。

Abstract:

Studying the inhibitory effect of different solvent extraction sites of Plumeria rubra (water extract,n-butanol extract,petroleum ether extract,ethyl acetate extract) on degranulation of mast cells.And the mechanism of improving type I hypersensitivity by effective active components of P. rubra was predicated by network pharmacology method and molecules docking.The RBL-2H3 cells were used as the experimental materials,Tween 80 as the model reagent to induce the degranulation of RBL-2H3 cells.The anti-pruritus effects of different extracts were compared.The prediction targets and disease targets of P. rubra were integrated to obtain the key targets.Molecular docking was used to virtual verify the binding ability between the effective active components of P. rubra and core targets.The cell experiment showed that the ethyl acetate extract of P. rubra had obvious effect on the anti-hypersensitivity.And the anthocyanins and flavonoids of treating hypersensitivity in P. rubra may be related to D(2) dopamine receptor,P2Y purinoceptor 2,5-hydroxytryptamine receptor 2A,P2Y purinoceptor 12,muscarinic acetylcholine receptor M1,5-hydroxytryptamine receptor 2C,muscarinic acetylcholine receptor M2,alpha-1D adrenergic receptor,alpha-1A adrenergic receptor,P2Y purinoceptor 1.
