AB  - The most successful therapeutic strategy in the treatment of Alzheimer's disease (AD) is directed toward increasing levels of the neurotransmitter acetylcholine (ACh) by inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), the enzymes responsible for its hydrolysis. In this paper, we extended our study on 4-aminoquinolines as human cholinesterase inhibitors on twenty-six new 4-aminoquinolines containing an n-octylamino spacer on C(4) and different substituents on the terminal amino group. We evaluated the potency of new derivatives to act as multi-targeted ligands by determining their inhibition potency towards human AChE and BChE, ability to chelate biometals Fe, Cu and Zn, ability to inhibit the action of β-secretase 1 (BACE1) and their antioxidant capacity. All of the tested derivatives were very potent inhibitors of human AChE and BChE with inhibition constants (Ki) ranging from 0.0023 to 1.6 μM. Most of the compounds were estimated to be able to cross the blood-brain barrier (BBB) by passive transport and were nontoxic to human neuronal, kidney and liver cells in concentrations in which they inhibit cholinesterases. Generally, newly synthesised compounds were weak reductants compared to standard antioxidants, but all possessed a certain amount of antioxidant activity compared to tacrine. Of the eleven most potent cholinesterase inhibitors, eight compounds also inhibited BACE1 activity at 10–18%. Based on our overall results, compounds 8 with 3-fluorobenzyl, 11 with 3-chlorobenzyl and 17 with 3-metoxy benzyl substituents on the terminal amino group stood out as the most promising for the treatment of AD; they strongly inhibited AChE and BChE, were non-toxic on HepG2, HEK293 and SH-SY5Y cells, had the potential to cross the BBB and possessed the ability to chelate biometals and/or inhibit the activity of BACE1 within a range close to the therapeutically desired degree of inhibition.

AB  - Infective diseases have become health threat of
a global proportion due to appearance and
spread of microorganisms resistant to majority
of therapeutics currently used for their treatment.
Therefore, there is a constant need for
development of new antimicrobial agents, as
well as novel therapeutic strategies.
Quinolines and quinolones, isolated from
plants, animals, and microorganisms, have
demonstrated numerous biological activities
such as antimicrobial, insecticidal, antiinflammatory,
antiplatelet, and antitumor. For
more than two centuries quinoline/quinolone
moiety has been used as a scaffold for drug
development and even today it represents an
inexhaustible inspiration for design and development
of novel semi-synthetic or synthetic
agents exhibiting broad spectrum of
bioactivities. The structural diversity of
synthetized compounds provides high and
selective activity attained through different
mechanisms of action, as well as low toxicity
on human cells. This review describes quinoline
and quinolone derivatives with
antibacterial, antifungal, anti-virulent,
antiviral, and anti-parasitic activities with the
focus on the last 10 years literature.
