The preparation and activity against Plasmodium berghei of derivatives of 1-(4-methoxycinnamoyl)-4-(5-phenyl-4-oxo-2-oxazolin-2-yl)piperazine are described. Replacement of the cinnamoyl group was accomplished by acylation or alkylation of 1-(5-phenyl-4-oxo-2-oxazolin-2-yl)piperazine. Modifications of the 5-phenyl group were prepared either by a sequence of reactions involving mandelic ester-pemoline-piperazine
描述了1-(4-甲氧基肉桂酰基)-4-(5-苯基-4-氧代-2-恶唑啉-2-基)哌嗪的衍生物的制备及其对伯氏疟原虫的活性。通过1-(5-苯基-4-氧代-2-恶唑啉-2-基)哌嗪的酰化或烷基化来完成肉桂酰基的取代。5-苯基的修饰可以通过一系列涉及扁桃酸酯-二氢萘-哌嗪-哌莫啉的反应或通过5-芳基-2-硫-2,4-恶唑烷二酮与哌嗪或N-取代的哌嗪的反应来制备。以类似的方式,使匹莫林与N-芳基哌嗪,六氢-1H-1,4-二氮杂和2,6-二甲基哌嗪反应,以提供N-芳基哌嗪匹莫林衍生物和哌嗪部分的变异。制备了几种化合物,其中2-恶唑啉-4-酮环被其他杂环取代,以及几种开链类似物。发现有五个化合物(其中三个被5-苯基对位取代)和两个N-芳基哌嗪哌莫林衍生物对柏氏疟原虫有活性。剩余的活性化合物具有肉桂酰基的变化和5-苯基的取代。
