A clerodane diterpene with antibacterial activity from Ajuga lupulina.[Pubmed: 9208462]
The structure of a new diterpene, C30H46O11, with antibacterial activity against Pseudomonas aeruginose and Escherichia coli, isolated from the fresh whole plants of Ajuga lupulina (Labiatae) was established to be 2 beta-hydroxy-2-methylbutanoyl-3 alpha-lupulin (3-deoxy-14,15-dihydro-2-hydroxy-15-methoxycaryoptinol 2-methylbutanoate), by means of X-ray crystallographic analysis. The present study confirms that the two six-membered rings are in ideal chair conformations.
Antibacterial neoclerodane diterpenoids from Ajuga lupulina.[Pubmed: 8759163]
The whole plants of Ajuga lupulina afforded five compounds, including three new clerodane diterpenes, lupulins A-C (1-3), whose structures were elucidated by spectral methods. Among these compounds, lupulins A (1) and B (2) as well as the acid hydrolysate (5) of lupulin D (4) showed antibacterial activities against Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli.
