Synthesis of New 1,2,3,4-Tetrahydroquinoline Hybrid of Ibuprofen and Its Biological Evaluation

open access: yesMolbank, 2022
Herein we report the obtaining of 1-(3,4-dihydroquinolin-1(2H)-yl)-2- (4-isobutylphenyl)propan-1-one and its characterization. The newly obtained hybrid and its derivatives (hybrids of ibuprofen with 1,2,3,4-tetrahydroisoquinoline, and piperidine) were ...

Antinociceptive Effect of Cinnamaldehyde in Male Mice: Investigation of the Mechanisms of Action Through In Silico and In Vivo Approaches

open access: yesChemistry &Biodiversity, Volume 23, Issue 4, April 2026.
ABSTRACT Cinnamaldehyde (CA), a major component of Cinnamomum spp. essential oils, has recognized bioactivity, including possible analgesic effects. However, its acute antinociceptive mechanisms remain unclear. This study assessed the influence of CA (15, 30, and 60 mg/kg, p.o.) on locomotor and exploratory behaviors via rotarod and open field tests in

Trisubstituted Pyrimidines as Efficacious and Fast-acting Antimalarials [PDF]

open access: yes, 2016
In this paper we describe the optimization of a phenotypic hit against Plasmodium falciparum, based on a trisubstituted pyrimidine scaffold. This led to compounds with good pharmacokinetics and oral activity in a P. berghei mouse model of malaria.
