A series of bufalin-3-yl nitrogen-containing-carbamate derivatives 3 were designed, synthesized, and evaluated for their proliferation inhibition activities against human cervical epithelial adenocarcinoma (HeLa) cell line. The structure–activity relationships (SARs) of this new series are described in this paper. Cytotoxicity data revealed that the C3 moiety had an important influence on cytotoxic...
Six new cardenolides (1, 2 and 11–14), along with ten known ones, were isolated from the root bark of Calotropis gigantea. The structural determination was accomplished by the 1D- and 2D-NMR spectrum as well as ESIMS analysis. The isolated compounds were evaluated for their in vitro growth inhibitory activity against human A549 and Hela cell lines. The results suggested that some of these cardenolides...
A series of bufalin 3-nitrogen-containing-ester derivatives (2–6) were designed, synthesized, and evaluated for their proliferation inhibition activities against human cervical epithelial adenocarcinoma (HeLa) and non-small-cell lung cancer (A549) cell lines. The structure–activity relationships (SARs) of this new series were described in this paper. Cytotoxicity data revealed that C3 moiety had important...
Estrogen results in the suppression of experimental allergic encephalomyelitis (EAE), a frequently used experimental animal model of multiple sclerosis (MS). The mechanism by which estrogen acts in diseases with an autoimmune background is less clear. Here, we used splenic dendritic cells (DC) from the Lewis rats EAE model as target cells, and explored the pathway of estrogen in immune modulation...
