Anew series of antinociceptive compounds belonging to the N-acylarylhydrazone (NAH) class were synthesized from natural safrole (7). The most analgesic derivative represented by 10f, [(4'-N,N-dimethylaminobenzylidene-3-(3', 4'-methylenedioxyphenyl)propionylhydrazine], was more potent than dipyrone and indomethacin, used as standards. The NAH compounds(More)
This paper describes the synthesis and anti-inflammatory activity of new N-phenyl-phthalimide sulfonamides (3a-e) and the isosters N-phenyl-phthalimide amides (4a-e), designed as hybrids of thalidomide (1) and aryl sulfonamide phosphodiesterase inhibitor (2). In these series, compound 3e (LASSBio 468), having a sulfonyl-thiomorpholine moiety, showed potent(More)
We report the design, the synthesis and the biological evaluation of the analgesic and anti-inflammatory activities of furoxanyl N-acylhydrazones (furoxanyl-NAH) by applying molecular hybridization approach. Hybrid compounds with IL-8-release inhibition capabilities were identified. Among them, furoxanyl-NAH, 17, and benzofuroxanyl-derivative, 24, together(More)
In this paper, we report the synthesis and pharmacological evaluation of pyrazine N-acylhydrazone (NAH) derivatives (2a-s) designed as novel analgesic and anti-inflammatory drug candidates. This series was planned by molecular simplification of prototype 1 (LASSBio-1018), previously described as a non-selective cyclooxygenase inhibitor. Derivatives 2a-s(More)
In this paper, we report the structural design, synthesis, trypanocidal activity and docking studies of novel quinoxaline-N-acylhydrazone (NAH) derivatives, planned as cruzain inhibitors candidates, a cysteine protease essential for the survival of Trypanosoma cruzi within the host cell. The salicylaldehyde N-acylhydrazones 7a and 8a presented IC(50) values(More)
Emphysema is an intractable pulmonary disease characterized by an inflammatory process of the airways and lung parenchyma and ongoing remodeling process in an attempt to restore lung structure. There is no effective drug therapy that regenerates lung tissue or prevents the progression of emphysema; current treatment is aimed at symptomatic relief. We(More)
AIM In the search for new antithrombotic drug candidates, the synthesis and anti-platelet activity of a new series of N-acylhydrazones that were designed as thrombin inhibitors has been previously described. The aim of this work was to further characterize the effects of these compounds on thrombin-induced platelet aggregation and induced thrombosis in(More)
Cyanobacterial blooms that generate microcystins (MCYSTs) are increasingly recognized as an important health problem in aquatic ecosystems. We have previously reported the impairment of pulmonary structure and function by microcystin-LR (MCYST-LR) exposure as well as the pulmonary improvement by intraperitoneally injected (i.p.) LASSBio 596. In the present(More)
