cyclic substitute of the unsaturated alkyl chain of the natural ligand, capsaicin. Accordingly, a new class of amides was synthesized in good yield and high purity and their molecular recognition against the target was investigated by means of docking experiments followed by molecular dynamics simulations, in order to rationalize their geometrical and thermodynamic profiles. The pharmacological properties
鉴定出4-(噻吩-2-基)丁酸是天然配体辣椒素的不饱和烷基链的环状取代基。因此,以高收率和高纯度合成了一类新的酰胺,并通过对接实验和随后的分子动力学模拟研究了其对目标的分子识别性,以合理化它们的几何和热力学特征。这些新化合物的药理特性表示为激活(EC 50)和脱敏(IC 50)效能。发现几种化合物可激活TRPV1通道,尤其是衍生物1和10表现为与辣椒素相比具有良好功效的TRPV1激动剂。还评估了最有前途的化合物1对角质形成细胞和表达TRPV1受体的分化人成神经细胞瘤细胞系的氧化应激的保护作用,以及其体内的细胞毒性和镇痛活性。
