A series of 2-(3- and 4-substituted phenyl)-3-[3-(N, N-dimethyl-amino)propyl]-1,3-thiazolidin-4-ones acting as H1-antihistaminics was investigated with a combined Hansch-CoMFA approach. The substituents at the 3- and 4-positions of the phenyl ring have been described through steric, electronic and hydrophobic parameters and correlated with pA2 values. The obtained quantitative models suggest that affinity to the receptor is promoted by hydrophobic and small 4-substituents and by 3- and 4-substituents generating a positive electrostatic potential towards a complementary receptor region.
采用Hansch-CoMFA联合方法研究了一系列作为H1抗组胺剂的2-(3-和4-取代苯基)-3-[3-(N,N-二甲基氨基)丙基]-1,3-噻唑烷-4-酮。通过空间、电子和疏水参数描述了苯环3-位和4-位的取代基，并将其与pA2值相关联。所得的定量模型表明，疏水性和小的4-取代基以及在互补受体区域产生正静电势的3-和4-取代基可促进对受体的亲和力。
