Bacteria of the Roseobacter clade are abundant marine bacteria and are important contributors to the global sulfur cycle. The volatiles produced by two of its members, Phaeobacter gallaeciensis and Oceanibulbus indolifex, were analyzed to investigate whether the released compounds are derived from sulfur metabolism, and which biosynthetic pathways are involved in their formation. Both bacteria emitted different sulfides and thioesters, including new natural compounds such as 5-methyl phenylethanethioate (16) and butyl methanesulfonate (21). The S-methyl alkanoates were identified by comparison with standards that were synthesized from the respective methyl alkanoates by a new method using an easily prepared aluminium/sulfur reagent. Phaeobacter gallaeciensis is also able to produce tropone (37) in large amounts. Its biosynthesis was investigated by various feeding experiments, showing that 37 is formed via a deviation of the phenylacetate catabolism. The unstable tropone hydrate 42 was identified as an intermediate of the tropone biosynthesis that was also released together with tropolone (38). The Royal Society of Chemistry 2010.

The prolactin production inhibition agent of the present invention containing a condensed cyclic compound, which is characterized by containing a condensed bicyclic structure of an optionally substituted homo or hetero 5- to 7-membered ring with an optionally substituted homo or hetero 5- to 7-membered ring, or a salt thereof, can be used, as a medicine, for the prophylaxis or therapy of diseases accompanied with an excess prolactin production or diseases having enhanced reactivity with prolactin, or is useful for inhibiting puerperal lactation, and also useful as a prophylactic or therapeutic agent of galactorrhea, hyperprolactinemic ovulation disturbance, amenorrhea-galactorrhea syndrome, prolactinoma, and besides, interbrain tumor, and acromegaly, pituitary gigantism.
