일반 설명
Oenothein B is a dimeric ellagitannin compound which is found commonly in genusOenothera.
애플리케이션
Oenothein B may be used as a reference standard for the determination of oenothein B in aqueous extracts of Epilobii angustifolli herba and Epilobium angustifolium L. by high performance thin-layer chromatography (HPTLC)-densitometry, in plant materials by HPLC combined with diode array detector (DAD) and mass spectrometry (MS) and in Eucalyptus globulus leaves by HPLC-DAD coupled to electrospray ionization (EIS) MS.

Oenothein B, a macrocircular dimeric ellagitannin, was found to be a potent and specific inhibitor of poly(ADP-ribose) glycohydrolase. Oenothein B suppressed glucocorticoid-sensitive mouse mammary tumor virus (MMTV) transcription in 34I cells. This suppression was accompanied by inhibition of glucocorticoid-induced endogeneous

The formation of ATP produced from poly(ADP-ribose) [(ADP-R)n] has been suggested to be required to repair damaged DNA. Here we investigate whether this ATP is involved in DNA replication processes during DNA repair. Poly(ADP-ribosyl)ated mid-S phase cell nuclei, which were
