โœฆ Synopsis


THE stereochemistry of ring A of some of the cucurbitacins has been discussed in a previous communication. 4 We wish to report now the experiments which led us to present most of the stereochemistry of the four naturally occurring cucurbitacins: elatericin A (Ia), cucurbitacin B (Ib), elatericin B (IIa) and elaterin (IIb), leaving only the configuration of C-9 undetert .A !Q u , d r f a R=H, R'=H r'-) R=H, R'=Ac \I 'Y c R=Ac,R'=H d R=Ac,R'=Ac

Cucurbitacin B, a natural triterpenoid is well-known for its strong anticancer activity, and recent studies showed that the compound inhibits JAK/STAT3 pathway. In this study, we demonstrate for the first time that cucurbitacin B is also a potent inhibitor of NF-kB activation. Our results showed tha
