From a fermentation broth of Streptomyces albolongus obtained from Elephas maximus feces, nine bafilomycins (1–9) and seven odoriferous sesquiterpenoids (10–16) were isolated. The structures of the new compounds, including three bafilomycins, 19-methoxybafilomycin C1 amide (1), 21-deoxybafilomycin A1 (2), and 21-deoxybafilomycin A2 (3), and two sesquiterpenoid degradation products, (1β,4β,4aβ,8aα)-4,8a-dimethyloctahydronaphthalene-1,4a(2H)-diol (10) and (1β,4β,4aβ,7α,8aα)-4,8a-dimethyloctahydron...

Abstract Odoriferous terpene metabolites of bacterial origin have been known for many years. In genome-sequenced Streptomycetaceae microorganisms, the vast majority produces the degraded sesquiterpene alcohol geosmin. Two minor groups of bacteria do not produce geosmin, with one of these groups instead producing other sesquiterpene alcohols, whereas members of the remaining group do not produce any detectable terpenoid metabolites. Because bacterial terpene synthases typically show no significan...

Two new compounds, isostreptazolin (1) and sannaphenol (2), were isolated from the culture broth of Streptomyces sannanensis and their structures elucidated on the basis of 1D and 2D NMR as well as MS, IR and UV spectroscopic data analysis. The cytotoxic activity of 1 and 2 were evaluated. Both compounds were inactive against H460 and HeLa cell lines at 100 mM.

Most terpenoids have been isolated from plants and fungi and only a few from bacteria. However, an increasing number of genome sequences indicate that bacteria possess a variety of terpenoid cyclase genes. We characterized a sesquiterpene cyclase gene (SGR2079, named gcoA) found in Streptomyces griseus. When expressed in Streptomyces lividans, gcoA directed production of a sesquiterpene, isolated and determined to be (+)-caryolan-1-ol using spectroscopic analyses. (+)-Caryolan-1-ol was also dete...

Two new sesquiterpenes, 15-hydroxy-T-muurolol (3d) and 11,15-dihydroxy-T-muurolol (3e), along with the plant cadinenes T-muurolol (3f) and 3 alpha-hydroxy-T-muurolol (3g), were isolated from the marine-derived Streptomyces sp. M491. Their absolute configuration was established via NMR spectroscopy and X-ray crystallography of 3-oxo-T-muurolol (3a), which was reisolated from this strain. In addition, the absolute configuration of further sesquiterpenes previously reported from this strain was rev...

(-)-Geosmin (1, blue) is an important odor component produced by many bacteria, including actinomycetes, myxobacteria, and cyanobacteria, but has also been reported for eukaryotic organisms such as fungi, liverworts, insects, and plants. Recent research has shown that the biosynthesis of 1 starts with the cyclization of farnesyl pyrophosphate to (1(10)E,5E)-germacradien-11-ol (2, yellow), the first key intermediate en route. In a retro-Prins-reaction acetone is lost, and the second key intermedi...

Abstract The ether extract of the liverwort Porella perrottetiana afforded (−)-α-eudesmol, which showed an opposite sign of the optical rotation to that found in higher plants. Present work on the absolute configuration and an optical purity of (−)-α-eudesmol strongly suggested that the positive values (e.g.+28.5°) described in many previous papers should be revised. Since the absolute configuration of (−)-α-eudesmol was identical to that of (+)-β-eudesmol found in the higher plants, it was appa...

The essential oil from the rhizomes of Hedychium gardnerianum Roscoe (‘Kahili ginger’) contains about 30% of sesquiterpenes, mainly cadinane derivatives. The following new sesquiterpenes were identified by their NMR and MS data: α-corocalene epoxide (104); 1,10;7,10-bisepoxy-1,10-seco-calamenene (68); 6,7;7,10-bisepoxy-6,7-seco-calamenene (74); 7-epi-trans- (60) and 7-epi-cis-sesquisabinene hydrate (69); 10-epi-cubenol (78); and ar-curcumen-1,10-diol (108).

Abstract Molecular identification suggested an edible mushroom, which was previously named as Craterellus odoratus should be revised as Montagnula donacina . A chemical re-investigation of the culture broth of this fungus resulted in the isolation of four rare tetracyclic bergamotane-type sesquiterpenoids, namely donacinolides A and B, donacinoic acids A and B, and three cadinane-type ones, namely donacinols A–C and a meroterpenoid ( Z )-4-hydroxy-3-(3-hydroxy-3-methylbut-1-en-1-yl)benzoic acid....
