that the derivatives o f 2-arylaminocinchoninic acid hydrazides exhibit an anfiinflarnmatory action that is most pronounced in the arylidene and 2-oxoindoline-3-ylidene derivatives. In continuation of that work, we have synthesized and characterized a series of 2-aminocinchoninic acid hydrazides on the basis of esters of 2-arylaminocinchoninic acids ( I a Id) having various substituents at the amino
在以前的工作 [I, 2] 中,我们已经确定 2-芳基氨基辛可宁酸酰肼的衍生物表现出抗炎作用,这在亚芳基和 2-氧代二氢吲哚-3-亚基衍生物中最为明显。在继续这项工作的过程中,我们基于在氨基和喹啉环的第 5 位具有各种取代基的 2-芳基氨基辛可宁酸 (I a Id) 的酯类合成并表征了一系列 2-氨基辛可宁酸酰肼( IlIg,表1)。3 此外,我们还合成了这些 2-芳基氨基辛可宁酸与丙酮酸的腙 (II Ia IIIc)。
