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.
天然儿茶酚、醌和醌甲烯二萜类化合物,具有雪松烃(15-去氧福尔斯特酮、税烯酮)和托塔烃(分散酮、12,13-二羟基-8,11,13-托塔烯-6-酮)以及桃金娘烃(宁比二醇、去氧宁比二醇)骨架,通过对苯酚进行邻位氧化,使用对氯苯甲酰过氧化物合成。此外,测量了这些二萜及之前合成的天然二萜对耐甲氧西林金黄色葡萄球菌(MRSA)和丙酸杆菌的最低抑菌活性,这些细菌引起与痤疮相关的严重皮肤感染。Abieta醌甲烯和8,11,13-托塔烯-12,13-二醇对金黄色葡萄球菌(MRSA)和丙酸杆菌显示出强效活性,并且在口服给药于小鼠时没有严重毒性。
