The synthesis of mono- and dihydroxy aromadendrane sesquiterpenes, starting from natural (+)-aromadendrene-III
摘要:
The monoalcohols (-)-globulol (2), (-)-epiglobulol (3), (-)-ledol (4), and (+)-viridiflorol (5) were synthesized from (+)-aromadendrene (1). The cis-fused alloaromadendrone (14), the key intermediate used in the synthesis of 4 and 5, was obtained from the trans-fused apoaromadendrone (13) via a selective protonation of the thermodynamic enol trimethylsilylether 15. After hydroxylation of the tertiary C11 of 13 with RuO4, (+)-spathulenol (6), (-)-allospathulenol (7), and the aromadendrane diols 8-11 could be prepared. Compounds 2-11 were tested for antifungal properties, but their activity was only moderate.

The present invention relates to a detergent composition for the control and removal of biofilms, which have been formed on a surface. The detergent composition comprises a combination of a mannanase and a botanical active ingredient, so that the combined action of both components provides a high efficiency in the elimination of biofilms adhered on surfaces, both in open areas and in closed areas. It also relates to a method for removing the biofilm in which this composition is used, and to the use thereof.
The present invention relates to methods for producing oxygenated terpenoids. Polynucleotides, derivative enzymes, and host cells for use in such methods are also provided.

Disclosed is an adjuvant for improving the bioavailability of bioactive compositions. The adjuvant is prepared from a byproduct of mint flavor production. In vitro and in vivo testing confirms effectiveness. The adjuvant contains a mixture of compounds which is effective to improve the oral bioavailability of a bioactive composition normally having limited absorptivity, and it comprises a mixture of nonpolar compounds and compounds with some polar characteristics. In preferred form the nonpolar compounds comprise compounds selected from a group that includes terpene hydrocarbons and terpene derivatives and the compounds with some polar characteristics comprise compounds selected from a group that includes aldehydes, alcohols and ketones. The preferred compositions will have a ratio of nonpolar compounds and compounds with some polar characteristics is within the range of from 5:1 to 20:1. The adjuvants can enhance delivery of CoQ10 and other bioactive compositions, such as carotenoids (e.g., β-carotene), curcuminoids, lycopene, resveratrol, flavonoids and other phenolic compounds, organosulfur compounds, saponins, sterols, stanols, and mixtures of at least two of these, to the interior cellular environment, including organelles, such as the mitochondria.
