log P values and the polar surface area (PSA) values were calculated. Substitution of the methylsulfinyl group (CH3S(O)–R) in 6-MITC with a formyl (CHO–R), a methylsulfanyl (CH2S–R) or a methyl (CH3–R) group reduced the activities of the parent isothiocyanate. Substitution with a formyl group resulted in lower lipophilicity (log P value) whereas substitution with a methylsulfanyl or methyl group resulted
对具有不同作用机理的新型抗炎药的需求不断增长。我们基于辛辣香料山葵(Wasabia japonica)中发现的6-(甲基亚磺酰基)己基异硫氰酸酯(6-MITC)合成了一系列异硫氰酸酯2b - h。注意到使用小鼠巨噬细胞样细胞系J774.1对肿瘤细胞体外生长的抑制活性和一氧化氮(NO)的产生。通过Hartree-Fock / 3-21G模型优化所有异硫氰酸酯,并计算log P值和极性表面积(PSA)值。的甲基亚磺酰基的取代(CH 3 S(O)-R)在6- MITC与甲酰基(CHO-R),甲基硫(CH 2S–R)或甲基(CH 3 –R)基团会降低母体异硫氰酸酯的活性。用甲酰基取代会导致较低的亲脂性(log P值),而用甲硫基或甲基取代会导致较低的PSA值。异硫氰酸酯的抑制活性显示出与其PSA值更好的相关性,而不是其分配系数(log P)值。具有较高PSA值和一定程度log P值的异硫氰酸酯 可能具有强大的生物活性。
