  Synthesis of polyhydroxylated aromatic mandelic acid amides and their antioxidative potential

  摘要：

  Six hydroxymandelic acid amides of phenolic amines were synthesized by condensation of 3,4-dihydroxymandelic or 4-hydroxy-3-methoxymandelic acid N-succinimidyl esters and several phenolic benzylamino and phenethylamino hydrochlorides in moderate to good yield. The radical scavenging activities determined by 2,2-diphenyl-1-picrylhydrazyl assay and superoxide trapping assay were superior compared to standards L-ascorbic acid, a-tocopherol, and butylated hydroxytoluene (BHT). The antioxidative activities tested by accelerated autoxidation of bulk Lipids were 2-3.5 times more potent compared to standards alpha -tocopherol and BHT. 3,4-Dihydroxymandelic acid dopamide (4b) and 4-hydroxy-3-methoxymandelic acid dopamide (4a) showed the best overall performance as antioxidants.

  摘要：

  合成了几种苯甲醛肟，苯甲醛-O-乙基肟和对乙酰氨基苯甲酸，并通过基于酪氨酸酶催化的L-DOPA氧化的分析，评估它们作为酪氨酸酶抑制剂。苯甲醛肟本身仅是一种弱抑制剂，而其衍生物在对位和间位具有一个或两个羟基或甲氧基部分则降低了酪氨酸酶的活性。苯乙酮肟和三取代的苯甲醛肟没有抑制活性。3,4-二羟基苯甲醛-O-乙基肟（0.3 +/- 0.1 micromol L（-1））的IC（50）与托酚酮（0.13 +/- 0.08 micromol L（-1））的幅度相同，一个迄今为止已知的最佳酪氨酸酶抑制剂之一。

  Several benzaldoximes, benzaldehyde-O-ethyloximes, and acetophenonoximes were synthesized and evaluated as tyrosinase inhibitors by an assay based on tyrosinase catalyzed L-DOPA oxidation. Whereas benzaldoxime itself is only a weak inhibitor, its derivatives with one or two hydroxy or methoxy moieties in para and meta positions depress tyrosinase activity. Acetophenonoximes and trisubstituted benzaldoximes
