An investigation of the olive phenols activity as a natural medicine
(Food & Drug Adminstration, 2018)
The natural antioxidants of olive oil have phenolic structure and their activities are related to the formation of stable derivatives. In this study, the single components of the phenolic fraction of olive oil (1,4-hydroquinone, ...
Simple and convenient preparation of novel 6,8-disubstituted quinoline derivatives and their promising anticancer activities
(Scientific Technical Research Council Turkey-Tubitak, 2013)
A short and easy route is described for 6,8-disubstituted derivatives of quinoline and 1,2,3,4-tetrahydroquinoline from 6,8-dibromoquinolines 2 and 7 by various substitution reactions. While copper-promoted substitution ...
SAR Evaluation of Disubstituted Tacrine Analogues as Promising Cholinesterase and Carbonic Anhydrase Inhibitors
(Assoc Pharmaceutical Teachers India, 2019)
Background: The inhibition of both hydrolysis products of acetylcholine (ACh), Acetylcholinesterase (AChE) and Butyrylcholinesterase (BChE), is essential for successful treatment of Alzhemier patients. Objectives: This ...
Synthesis, characterization, crystal structures, theoretical calculations and biological evaluations of novel substituted tacrine derivatives as cholinesterase and carbonic anhydrase enzymes inhibitors
(Elsevier Science Bv, 2019)
The six and seven hydrocycle membered disilylanilino acridine (tacrine) analogues (9-11) were synthesized by one-pot procedures. The structures of novel silyl tacrine derivatives were characterized by NMR spectroscopy, ...
