Osteoclastogenesis Regulation Metabolites from the Coral-Associated Fungus Pseudallescheria boydii TW-1024-3.

Summary of "Osteoclastogenesis Regulation Metabolites from the Coral-Associated Fungus Pseudallescheria boydii TW-1024-3."

Three new compounds (9-11) were isolated together with eight known analogues from the fungus Pseudallescheria boydii associated with the South China Sea soft coral Sinularia sandensis. The structures of the new compounds were elucidated on the basis of the spectroscopic analysis, and the absolute configurations including the sulfur stereogenic center of a sulfoxide moiety were determined by comparison of experimental ECD spectra to TDDFT/ECD calculations. Epimeric chiral sulfoxides differing in the absolute configuration of the sulfur chirality center could be efficiently distinguished and assigned by comparing the experimental ECD to those of calculations for the sulfur epimers. In the in vitro biotests for osteoclastogenesis effects, compounds 1, 5, 7, and 10 exhibited a stimulatory activity, while compound 3 displayed an inhibitory activity.

Medical and Biotech [MESH] Definitions

Marine ridges composed of living CORALS, coral skeletons, calcareous algae, and other organisms, mixed with minerals and organic matter. They are found most commonly in tropical waters and support other animal and plant life.

A mitosporic fungal genus previously called Monosporium. Teleomorphs include PSEUDALLESCHERIA.

Ascomycetous fungi, family Microascaceae, order Microascales, commonly found in the soil. They are causative agents of mycetoma, maduromycosis, and other infections in humans.

Symbiotic combination (dual organism) of the MYCELIUM of FUNGI with the roots of plants (PLANT ROOTS). The roots of almost all higher plants exhibit this mutually beneficial relationship, whereby the fungus supplies water and mineral salts to the plant, and the plant supplies CARBOHYDRATES to the fungus. There are two major types of mycorrhizae: ectomycorrhizae and endomycorrhizae.

A secreted member of the TNF receptor superfamily that negatively regulates osteoclastogenesis. It is a soluble decoy receptor of RANK LIGAND that inhibits both CELL DIFFERENTIATION and function of OSTEOCLASTS by inhibiting the interaction between RANK LIGAND and RECEPTOR ACTIVATOR OF NUCLEAR FACTOR-KAPPA B.
