on the ability of alkynoic esters and alkynones to induce a chemoselective cysteine modification of unprotected peptides. Thus, also following our previous findings on the impairment of vacuolar-type proton translocating ATPase functionality by activated carbonyl derivatives, we speculate that the formation of a vinyl sulfide linkage might be responsible for the nematicidal activity of the presented
本研究报告了一系列缺电子炔烃对根结线虫Meloidogyne incognita(Kofoid和White)Chitwood的强大杀线虫活性。有趣的是,我们发现吸电子羰基与炔三键的结合在诱导线虫麻痹和死亡方面极为有效。特别是EC 50/48 h的二甲基乙炔二羧酸盐(10),3-butyn-2-one(1)和丙酸甲酯(4)1.54±0.16、2.38±0.31和2.83±0.28 mg / L的化合物被证明是测试效果最好的化合物。较早的研究报道了炔基酯和炔酮诱导未保护肽的化学选择性半胱氨酸修饰的能力。因此,同样根据我们先前关于活化羰基衍生物损害液泡型质子易位ATPase功能的发现,我们推测形成乙烯基硫醚键可能是所呈现的电子缺陷炔的杀线虫活性的原因。
