  Synthesis of variously oxidized abietane diterpenes and their antibacterial activities against MRSA and VRE

  摘要：

  Variously oxidized 12 natural abietanes, 6,7-dehydroferruginol methyl ether (3), ferruginol (5), 11-hydroxy-12-oxo-7,9(11),13-abietatriene (7), royleanone (9), demethyl cryptojaponol (12), salvinolone (14), sugiol methyl ether (16), sugiol (17), 5,6-dehydrosugiol methyl ether (19), 5,6-dehydrosugiol (20), 6 beta -hydroxyferruginol (23), and taxodione (25) were synthesized. Antimicrobial activities of synthesized phenolic diterpenes and their related compounds against MRSA and VRE were evaluated. Phenols (12-hydroxyabieta-8,11,13-trien-6-one 22 and 23), catechols (12 and 14) and taxodione 25 showed potent activity with 4-10 mug/mL of MIC against MRSA and 4-16 mug/mL of MIC against VRE. (-)-Ferruginol showed more potent activity than natural type (+)-ferruginol. Quinone methide 7 showed the most potent activity with 0.5-1 mug/mL of MIC against both MRSA and VRE.

• Syntheses and Antibacterial Activities of Diterpene Catechol Derivatives with Abietane, Totarane and Podocarpane Skeletons against Methicillin-Resistant Staphylococcus aureus and Propionibacterium acnes

  日期：——

  Natural catechol, quinone and quinone methide diterpenes with abietane (15-deoxyfuerstione, taxodione) and totarane (dispermone, 12,13-dihydroxy-8,11,13-totaratriene-6-one), and podocarpane (nimbidiol, deoxynimbidiol) skeletons were synthesized using ortho-oxidation of phenol with meta-chlorobenzoyl peroxide. Minimum inhibitory activities of these diterpenes and previously synthesized natural diterpenes were measured against methicillin-resistant Staphylococcus aureus (MRSA) and Propionibacterium acnes, which cause serious skin infection associated with acne. Abietaquinone methide and 8,11,13-totaratriene-12,13-diol showed potent activities against S. aureus (MRSA) and P. acnes, and no serious toxicity by oral dose to mice.

  Oxidation at the C-11 position of methyl 12-hydroxyabieta-8,11,13-trien-18-oate (II) and ferruginol (XXXII) were successfully carried out using benzoyl peroxide, and the resulting phenols (VII and XXXVII) were further converted into taxodione (III), royleanone (IV), cryptojaponol (V), and methyl 11-hydroxy-12-methoxy-7-oxoabieta-8,11,13-trien-18-oate (VI).

  Podocarpic arid was converted to taxodione. Since the total synthesis of the former is recorded, this conversion implies a total synthesis of the latter.

  An asymmetric polyene cyclization (92% ee) strategy has been successfully applied for the first asymmetric total synthesis of oxidized abietane, anticancer agent, taxodione (1) sharing a trans-decalin system. Additionally, the total syntheses of pomiferin B (2) and gaultheric acid (3) (a nor-abietane) were achieved utilizing this unified approach.

  不对称多烯环化（92% ee ）策略已成功应用于共享反式十氢化萘系统的氧化松香烷、抗癌剂紫杉二酮（ 1 ）的首次不对称全合成。此外，利用这种统一方法实现了 pomiferin B ( 2 ) 和 gagatheric Acid ( 3 )（去甲松香烷）的全合成。
