triazinyl‐isoxazoles were afforded via an effective cycloaddition reaction between nitrile oxides and the scarcely described 2‐ethynyl‐4,6‐dimethoxy‐1,3,5‐triazine as dipolarophile. The biological evaluation of the newly synthesized compounds showed that the inhibition of human farnesyltransferase by zinc complexation could be improved with triazine‐isoxazole moieties. The replacement of the isoxazole unit
前所未有的三嗪基-异恶唑是通过腈氧化物和几乎没有描述的作为偶极体的 2-乙炔基-4,6-二甲氧基-1,3,5-三嗪之间的有效环加成反应得到的。新合成化合物的生物学评价表明,三嗪-异恶唑部分可以改善锌络合对人法呢基转移酶的抑制。用吡咯烷-2-酮取代异恶唑单元不利于抑制活性,而吡咯烷-2-硫酮衍生物则保留了生物学潜力。还评估了所选化合物破坏 pEGFP-CAAX 转染的中国仓鼠卵巢 (CHO) 细胞中蛋白质法呢基化的潜力。
