The experimental results of Caco-2 cell monolayer demonstrate that the apparent permeability coefficients(Papp) of resibufogenin and cinobufagin are higher than 10–6 cm/s, which indicates that both resibufogenin and cinobufagin have a good absorption in the small intestine. And the biotransformation result of human intestinal bacteria shows that resibufogenin has been transformed to 3-epiresibufogenin and cinobufagin has been transformed to 3-epicinobufagin, deacetylcinobufagin and 3-epideacetycinobufagin, respectively.展开更多

Detailed analysis of the 1H-NMR data showed that X-ray structure of 1 would be expected to closely resemble the solution conformation in chloroform. Compound 1 was inactive for the inhibition of PC3 and HepG2 cancer cells, but the parent compound cinobufagin showed potent inhibition with IC50 values of 0.145 and 5.48 μM, respectively, indicating that esterification at C（3） decreased the cytotoxic effect of 1.展开更多

Methods: A total of 104 cases of patients with middle and advanced primary hepaticcarcinoma who were treated in the oncology department from August 2018 to January 2020 were included as the study objects, andwere randomly divided into two groups according to different treatment regimens, 52 cases in each group. Both groups were treatedwith TACE once;the cinobufagin injection group was given intravenous infusion with 500 mL of 5% glucose injection and 10 mLof cinobufagin injection once a day. The elemene injection group was given intravenous infusion with elemene injection of 0.4 geach time and once a day. Both groups were treated for two courses, 15 days of continuous treatment with a rest of 15 days beingone course.

The 50% inhibitory concentrations（lCs0） of einobufagin and resibufoge- nin were （10.94±2.36） and （218±31） nmol/L, respectively, the 50% cytotoxic concentrations（CCs0） of them were （1277±223） and （1385±254） nmol/L, respectively, and the anti-EV71 selectivity index（SI50） of cinobufagin was 116.7, which are promisingly developed into drug. Using a VP1 detection assay and a constructed reporter luciferase, we found that cinobufagin and resibufogenin disrupted the synthesis of EV71 protein. However, neither of them inhibited EV71 RNA replication. Our study suggests that cinobufagin and resibufogenin are the promising candidates that should he fllrther investigated for the treatment of EV71 caused disease.展开更多

These compounds inhibit Na＋/K＋-ATPase in a dose-dependent manner. Compound 3c with an oxyethylamine side chain that is the same as that of istaroxime showed the most potent inhibi- tion, which was stronger than compound 3a with only hydroxyoxime moiety at C3 and compound 3b with a methy-lated hydroxyoxime moiety. Molecular docking was used to explore the binding modes of the target compounds with Na＋/K＋-ATPase, which suggested that the longer ethyl amine group at C3 oxime moiety of compound 3c could make stronger interaction with Na＋/K＋-ATPase via intermolecular charge-charge and H-bond interaction as compared with other derivatives.展开更多

However, neither of them inhibited EV71 RNA replication. Our study suggests that cinobufagin and resibufogenin are the promising candidates that should he fllrther investigated for the treatment of EV71 caused disease.

文摘Some cinobufagin oxime ether derivatives as potential Na＋/K＋-ATPase inkibitors were synthesized by following the side chain of istaroxime. These compounds inhibit Na＋/K＋-ATPase in a dose-dependent manner. Compound 3c with an oxyethylamine side chain that is the same as that of istaroxime showed the most potent inhibi- tion, which was stronger than compound 3a with only hydroxyoxime moiety at C3 and compound 3b with a methy-lated hydroxyoxime moiety. Molecular docking was used to explore the binding modes of the target compounds with Na＋/K＋-ATPase, which suggested that the longer ethyl amine group at C3 oxime moiety of compound 3c could make stronger interaction with Na＋/K＋-ATPase via intermolecular charge-charge and H-bond interaction as compared with other derivatives.
