5-isothiocyanato-2-(5-methyl-2-furyl)benzoxazole (35), and 5-isothiocyanato-2-(1-methyl-1H-2-pyrroly)benzoxazole (37), show 100% nematocidal activity and two, i.e., 5- and 6-isothiocyanato-2-(3-pyridinyl)benzoxazole (5) and 5- and 6-isothiocyanato-2-(3-pyridinyl)benzthiazole (21), show 10% taeniacidal activity at 0.2% in the diet. Two derivatives (5 and 21) show good nematocidal activity in sheep. Maximum
描述了22种异硫氰酸根合-2-吡啶基苯并恶唑和苯并噻唑的合成及抗寄生虫性能。概述了14种异硫氰酸根合-2-噻吩基-,-呋喃基-和-吡咯基苯并恶唑的制备和驱虫活性。在实验性感染了线虫Nematospiroides dubius(线虫)和Hymenolepis nana(带虫)的小鼠中,三种衍生物,即5-异硫氰酸根-2-(2-呋喃基)苯并恶唑(34),5-异硫氰酸根-2-(5-甲基-2) -呋喃基)苯并恶唑(35)和5-异硫氰酸根合-2-(1-甲基-1H-2-吡咯基)苯并恶唑(37)表现出100%杀线活性和5个和6个异硫氰酸根合-2- (3-吡啶基)苯并恶唑(5)和5-和6-异硫氰酸根基-2-(3-吡啶基)苯并噻唑(21)在饮食中显示10%的牛磺酸酸度,为0.2%。两种衍生物(5和21)在绵羊中显示出良好的杀线虫活性。
