Inhibitory effect on tumor necrosis factor-α (TNF-α) production by sinomenine derivatives with embedment of small drug-like nitrogen hetereocyclic moieties has been studied in this work. Several new sinomenine derivatives having chlorophenyl substituent have been found to exhibit much more potent TNF-α inhibitory activity than natural sinomenine and other derivatives.
The synthesis of C-ring quinoxaline-substituted sinomenine 1,2,3-triazole derivatives at the 4-OH via click reactions is accomplished, and a total of 16 novel sinomenine double N-heterocyclic derivatives are obtained in 74%–95% yields. The C-ring is first transformed into a 1,2-diketone structure under the action of hydrochloric acid, and then reacted with o-phenylenediamine to obtain a C-ring qui

Pathway blockers: In this study, three series of sinomeninederivatives were synthesized, and derivatives were evaluated for anticancer activity. Most SIN derivatives showed better antitumoractivity than SIN. Compound 11 c was found to be the most potent derivative against human MCF-7 breast cancer cells, with an IC50 value of 3.76 μM. Compound 11 c induced apoptosis via IL-6/PI3K/Akt/NF-κB signaling

Embedment of drug-like heterocyclic moieties was Successfully employed in the novel modification of the readily available but poorly bioactive natural alkaloid sinomenine. Application of the newly proposed approach afforded a number of more potent sinomenine-like molecules with a significantly high hit rate. Among these new analogous, up to 500-fold increase of in vitro immunosuppressive activity was achieved. Further biological experiments of representative compound 4b indicated that it might inhibit NF-kappa B activation induced by TNF-alpha in a dose dependent way and showed remarkable in vivo treatment effects against the mouse experimental autoimmune uveoretinitis (EAU) disease models.
