Antiangiogenic properties of substituted (Z)-(±)-2-(N-benzylindol-3-ylmethylene)quinuclidin-3-ol/one analogs and their derivatives
Graphical abstract
A series of substituted (Z)-(±)-2-(N-benzylindol-3-ylmethylene)quinuclidin-3-ols (1a–1k), (Z)-2-benzylindol-3yl-methylene)quinuclidin-3-ones (2a–2i), (Z)-(±)-2-(1H/N-methyl-indol-3-ylmethylene)quinuclidin-3-ol (3b), and substituted (Z)-(±)-2-(N-benzenesulfonylindol-3-yl-methylene)quinuclidin-3-ols and their derivatives (4a–4d) that incorporate a variety of substituents in both the indole and N-benzyl/benzene sulfonyl moieties were evaluated for their antiangiogenic activity using Human Umbilical Vein Endothelial Cells (HUVECs). Eight analogs were identified as potent angiogenesis inhibitors at a non-toxic concentration of 10 μM. The analog, 4b was identified as the most potent antiangiogenic agent. The mechanism of inhibition is consistent with inhibition of ENOX activity.

Discovery of novel quaternary ammonium compounds based on quinuclidine-3-ol as new potential antimicrobial candidates
2019, European Journal of Medicinal ChemistryCitation Excerpt :The best explored biological activity of quinuclidine derivatives is against the α7-nicotine acetylcholine receptor (α7 nAChR), as evidenced by the current phase II clinical trials of its several derivatives for treatment of schizophrenia and Alzheimer disease [9–11]. In addition, quinuclidine has also a wide spectrum of other biological activities such as anticholinergic, antiparasitic and antitumor activity, making it an attractive target for further research [12–15]. However, up until recently, little has been known about antimicrobial activity of quinuclidinium compounds.
Structure-property relationship of quinuclidinium surfactants-Towards multifunctional biologically active molecules
2016, Colloids and Surfaces B: BiointerfacesCitation Excerpt :The quaternary ammonium surfactants containing long alkyl chains exert bactericidal and fungicidal properties [8,10]. Furthermore, quinuclidinium and oxime based compounds are known to possess a broad range of biological and pharmacological activities [15–20]. These properties have been exploited as starting point for the design of antibacterial surfactants.
