  Compounds from Danshen. Part 4. Structure-activity relationship of miltirone, an active central benzodiazepine receptor ligand isolated from Salvia miltiorrhiza Bunge (Danshen)

  摘要：

  Twenty one o-quinonoid-type compounds and one coumarin-type compound related to miltirone (1) have been synthesized with the aim to identify the key structural elements involved in miltirone's interaction with the central benzodiazepine receptor. On the basis of their inhibition of [H-3]flunitrazepam binding to bovine cerebral cortex membranes, it is apparent that ring A of miltirone is essential for affinity. Although increasing the size of ring A from six-membered to seven- and eight-membered is well-tolerated, the introduction of polar hydroxyl groups greatly reduces binding affinity. The presence of 1,1-dimethyl groups on ring A is, however, not essential. On the other hand, the isopropyl group on ring C appears to be critical for binding as its removal decreases affinity by more than 30-fold. It can, however, be replaced with a methyl group with minimal reduction in affinity. Finally, linking ring A and B with a -CH2CH2- bridge results in analogue 89, which is 6 times more potent than miltirone at the central benzodiazepine receptor (IC50 = 0.05-mu-M).

• Facile synthesis of 1,2-dione-containing abietane analogues for the generation of human carboxylesterase inhibitors

  the synthesis of such compounds is complex. Here we describe a novel method for the generation of 1,2-dione containing diterpenoids using a unified approach, by which boronic acids are joined to vinyl bromo-cyclohexene derivatives via Suzuki coupling, followed by electrocyclization and oxidation to the o-phenanthroquinones. This has allowed the construction of a panel of miltirone analogues containing

  最近，基于丹参酮已经鉴定出一系列选择性的人羧酸酯酶抑制剂，其具有1，2-二酮基团的生物活性分子作为萘醌核心的一部分。不幸的是，这类化合物的合成很复杂。在这里，我们描述了一种使用统一方法生成含1,2-二酮的二萜类化合物的新方法，该方法将硼酸通过Suzuki偶联与乙烯基溴-环己烯衍生物连接，然后进行电环化并氧化成邻位-菲醌。这允许构建一组含有一系列取代基（甲基，异丙基，氟，甲氧基）的米替隆类似物，这些取代基已用于与两种人羧酸酯酶同工型发展初步的SAR。因此，我们已经合成这些酶（K的高度有效的抑制剂我 <15纳米），其保持所述芯丹参酮支架。因此，我们开发了一种简便易行且可重现的方法，用于合成abetanene类似物，从而产生了一系列米替农衍生物，这些衍生物将是评估羧酸酯酶生物学的有用工具化合物。
• Synthesis and Antioxidant Activity of Rosmariquinone and Several Analogues

  Rosmariquinone (1) and six analogues were chemically synthesized using an ultrasound-promoted Diels-Alder cycloaddition in yields of 35-90%. The analogues included substitution of the isopropyl at carbon 13 (C-13) with a hydrogen (5), methyl (6), or tert-butyl (4) substituent. The hydrogen-substituted analogue had the lowest yield at 35%, due in part to the instability of the compound to air, while the highest yields were achieved for the methyl (85%) and tert-butyl (90%) analogues. The 60% yield obtained for the C-14 methyl analogue (7; no C-13 isopropyl) may have been caused by the meta-substituted catechol inhibiting the cycloaddition. The final two analogues were ring A modifications and included the removal of one C-4 methyl (3; 80% yield) or both C-4 methyl (2; 85% yield) groups. The analogues were tested against rosmariquinone in light-sensitized oxidation of stripped soybean oil. Analogues 5 and 6 were significantly (P < 0.05) better antioxidants than rosmariquinone and all other analogues. The antioxidant properties of compounds 2-7 were not significantly different (P < 0.05) from each other while compounds 2 and 4 had significantly (P < 0.05) lower antioxidant activity than rosmariquinone. This study demonstrated the importance of structural characteristics of antioxidants and that natural antioxidants, such as rosmariquinone, can be improved through chemical modification.
