  Effect of Benzylic Oxygen on the Antioxidant Activity of Phenolic Lignans

  摘要：

  It has been clarified in the present investigation that a high degree of oxidation at the benzylic position of phenolic lignans bearing a 4-hydroxy-3-methoxybenzyl group reduces their antioxidant activity and that the antioxidant activity of the bis(4-hydroxy-3-methoxybenzyl)tetrahydrofuran lignan 2 is higher than that of the corresponding gamma-butyrolactone lignan 1. This was demonstrated by comparing the antioxidant activities of compounds 1 and 2 with those of the (benzyl)(hydroxybenzyl)tetrahydrofurans 3 and 4, the bis(hydroxybenzyl)tetrahydrofurans 7 and 8, the (benzoyl)(benzyl)tetrahydrofuran 6, and the dibenzoyltetrahydrofuran 9. The activity level of compound 2 was approximately the same potency as that of the tetrahydronaphthalene-tetrahydrofuran 5. These compounds possess either a 4-hydroxy3-methoxybenzyl group or a 4-hydroxy-3-methoxybenzoyl group as the benzyl or benzoyl group. An examination of radical scavenging activity showed differences of activity between diastereomers. To make this comparison possible, compounds 1-9 were synthesized using new synthetic routes for several of these lignans. In this investigation, stereoisomers of the (benzyl)(hydroxybenzyl)tetrahydrofurans 3 and 4 and liovils 7 and 8 were synthesized for the first time.

  芳香环上带有卤素和烷基的细胞毒性新型arcingenin衍生物的合成

  摘要：

  合成了新的木质素-9,9'-内酯（α，β-二苄基-γ-丁内酯木脂素），其细胞毒性高于arctigenin。众所周知的细胞毒性artigenin对HL-60细胞具有活性（EC 50  = 12μM），但是对HeLa细胞没有活性（EC 50  > 100μM）。具有木质素-9,9'-内酯结构的合成的（3,4-二氯，2'-丁氧基）衍生物55和（3,4-二氯，4'-丁基）衍生物66的EC 50值为分别针对HL-60细胞10μM和9.4μM。对于HeLa细胞，衍生物66的EC 50值为27μM。通过将活性与相应的9,9'-环氧结构（四氢呋喃化合物）进行比较，表明了55和66的内酯结构对于更高活性的重要性。木质素9,9'-内酯芳香环上的取代基影响细胞毒性水平，差异超过10倍。
