An Actinomycete, strain K-128, which was isolated from soil, formed a transfer product when the strain was cultured in a medium containing both stevioside and curdlan. The transfer product in culture broth was separated by DIAION HP-20 column and TOYOPEARL HW-40F column chromatographies. From structural studies, the transfer product was identified as C13-O-beta-6(2)-beta-glucosylsophorosyl-C19-...

A novel C19 homolignan, taiwanschirin D (1), possessing a 3,4-(1-[(Z)-2-methoxy-2-oxoethylidenel)pentano (2,3-dihydrobenzo[b]furan)-3(2-oxoacetate) skeleton, was isolated from the stem of Kadsura matsudai Hayata. Its structure was determined from physical and spectral data including 2D NMR spectra. The Anti-HBeAg test revealed that taiwanschirin D (1) had moderate activity at a concentration of...

Andererseits werden einige dieser aber auch zur Behandlung von COVID-19 genutzt. Um mehr über die Zusammenhänge zwischen und zu erfahren wurde 2020 Global Rheumatology Alliance (C19-GRA) gegründet.
