蛙皮降压肽(Sauvagine,Svg)是一种良好的促肾上腺皮质激素,释放因子2受体(CRF2R)激动剂,但它是一种非选择性激动剂,作用于CRF1R而产生副作用。为了探讨蛙皮降压肽类似物对CRF2R与CRF1R选择性的影响,本文使用正交因子(Orthogonal Factors,Orth-Factors)描述子,对45个蛙皮降压肽类似物与CRF2F、CRF1R的亲合力进行了QSAR研究,所建立的QSAR模型预测能力良好。通过QSAR模型信息,设计了17个蛙皮降压肽类似物,其中3个对CRF2R与CRF1R受体选择性良好(SQ:110,TQ:105,VQ:110),有进一步研究的价值。
Sauvagine (Svg) is a good corticotropin-releasing factor 2 receptor (CRF2R) agonist, but it is a non-selective agonist with side effects on CRF1R. In order to investigate the effect of the antihypertensive peptide analogues on the selectivity of CRF2R and CRF1R, we used Orthogonal Factors (Orth-Factors) descriptors to test the selectivity of CRF2R and CRF1R Helps to conduct QSAR research, and the established QSAR model has good predictive ability. Seventeen frog skin antihypertensive peptide analogues were designed based on the QSAR model information. Three of them have good selectivity for CRF2R and CRF1R receptors (SQ: 110, TQ: 105, VQ: 110).
