The synthesis of a new series of organochalcogen-derivatives, 2-alkyl/arylchalcogenyl-N-(4-aryl-1,3-thiazol-2-yl)acetamides 5a–r, provided products in satisfactory yields, which varied from 42% to 95%. All these novel compounds were screened for their in vitro free radical scavenging activity against 2,2-diphenyl-2-picrylhydrazyl (DPPH) and 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS)
合成了一系列新的有机硫属元素衍生物2-烷基/芳族硫属酰基-N-(4-芳基-1,3-噻唑-2-基)乙酰胺5a – r,所提供的产品收率令人满意,从42%达到95%。筛选了所有这些新型化合物的体外对2,2-二苯基-2-吡啶并肼基(DPPH)和2,2'-叠氮基-双-(3-乙基苯并噻唑啉-6-磺酸)(ABTS)的自由基清除活性部首。化合物5(m,h,i,f,q,g,l,c,n)是对ABTS自由基物种的有效清除剂,但对DPPH自由基的清除效果较差,表明这些化合物的抗氧化作用与质子化自由基清除剂活性有关。
