The stem bark and stem wood of Cinchona pubescens were found to owe their weak cytotoxic activity to the presence of quinovic acid. This acid and its 3-rhamnoside were isolated and characterized through several derivatives, all of which were assayed for their cytotoxicity.
A series of novel functionalized mono-, bis- and tris-(S)-{[(2S,4R,8R)-8-ethyl-quinuclidin-2-yl](6-methoxyquinolin-4-yl)}methanamines including ferrocene-containing derivatives was obtained by the reaction of the precursor amine with a variety of acylation agents. Their in vitro antitumor activity
TRAF6 is highly expressed in many tumors and plays an important role in the immune system. The aim of this study is to confirm anti-tumor activities of all naturally occurring Cinchona alkaloids that have been screened using computational docking program, and to validate the accuracy and specificity
Recently, we demonstrated that ferrocene-containing compounds with a cinchona moiety displayed marked anticancer activity. Here we report on the effects of the most promising isomers encompassing quinine- (compounds 4 and 5) and quinidine-epimers (compounds 6 and 7) - synthesized using improved
A series of eight new conjugates of salinomycin or monensin and Cinchona alkaloids were obtained by the Cu(I)-catalysed 1,3-dipolar Huisgen cycloaddition (click chemistry) of respective N-propargyl amides of salinomycin or monensin with four different Cinchona alkaloid derived azides. In vitro
A series of 27 cinchona alkaloid derivatives (1f-w, 2a-e and 3a-d) were investigated for their cytotoxic and trypanocidal activities using seven different cancer cell lines (KB, HeLa, MCF-7, A-549, Hep-G2, U-87 and HL-60), two normal cell lines (HDF and CHO) and bloodstream forms of Trypanosoma
