粗海绵提取物的酶筛选优先于2005年巴布亚新几内亚收集的Hyrtios sp.进行进一步研究。MeOH提取物含有普乌哌酮和四种普乌哌酮类似物(1、2、3、5和7)沿着一种新的非对映异构体,20-表-羟基胡马二烯酮(4)和一种新的类似物15-氧代-普乌哌酸(6)。4和6的补身烷萜核被快速去复制,并且改进的Mosher方法鉴定了4,而1D和2D NMR技术被用于解决6。这些化合物加上值得注意的储存库天然产物和标准品进行了测试,对三个脂氧合酶同工酶,人5-,12-和15-脂氧合酶。在人5-脂氧合酶试验中,通过Puupehenone(1)和jaspaquinol(9)显示了显著的效力和选择性特征,并鉴定了负责活性的结构因子。
Enzyme screening of crude sponge extracts prioritized a 2005 Papua New Guinea collection of Hyrtios sp. for further study. The MeOH extract contained puupehenone and four puupehenone analogs (1, 2, 3, 5, and 7) along with a new diastereomer, 20-epi-hydroxyhaterumadienone (4) and a new analog 15-oxo-puupehenoic acid (6). The drimane terpene core of 4 and 6 was rapidly dereplicated, and modified Mosher’s method identified 4 while 1D and 2D NMR techniques were used to solve 6. These compounds plus noteworthy repository natural products and standards were tested against three lipoxygenase isozymes, human 5-, 12- and 15-lipoxygenases. Significant potency and selectivity profiles were exhibited in the human 5-lipoxygenase assay by puupehenone (1) and jaspaquinol (9) and structural factors responsible for activity identified.
