Facile synthesis and anti-proliferative activity evaluation of quinoxaline derivatives

A series of ?drug-like? compounds based on quinoxaline scaffold with arylsulfonyl hydrazinyl, arylformyl hydrazinyl or arylsulfonyl groups at C-2 and aryloxy groups at C-3, were synthesized in 4 or 5 steps involving cyclization, chlorination and coupling reactions. Cellular anti-proliferative activities of these quinoxaline derivatives in vitro were determined, which revealed that the inhibitory potency and selectivity of 6f was comparable to that of the positive control.

New derivatives of quinoxaline – Syntheses, complex formation and their application as controlling ligands for zinc catalyzed epoxide-CO2-copolymerization

A series of amino-(type 3) as well as hydrazino-substituted quinoxalines (type 8) have been synthesized in order to study their ability to complex with iron(III) and zinc(II) ions. Cyclization of 2,3-dichloroquinoxaline (1) with a bis-amidine 9 leads to ring-fused quinoxalines of type 10. One of these compounds (10a) forms a unique macrocyclic hexameric complex 14 with zinc ions in the presence of 2,6-diisopropyl phenolate. In an analogous manner, the monomeric complexes 12 and 13 could be synthesized. All of these new zinc complexes catalyze the copolymerization of cyclohexene oxide and carbon dioxide with a high degree of selectivity in the resulting polymers.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Recent developments in the use and abuse of growth promoters

During the last few years, control within the European Union (EU) for illegal growth promoters in cattle and pigs revealed only a limited number of positives. Analysis of illegal preparations, however, showed that steroids, often (esters of) natural hormones, and beta-agonists are still used. Corticosteroids, controlled to a much lesser extent, seem to have become the most important group, while even thyreostats remain. Alarming information was obtained from specific investigations in which a large variety of products were found, some of which had never been reported to be misused in the field of growth promotion. For beta-agonists and quinoxaline compounds, analogues of known compounds are synthesised. Other compounds are readily available as they are registered as growth promoters in some countries outside Europe or are allowed for specific veterinary purposes. Some classes of veterinary drugs are misused for their secondary pharmacological effects, e.g. benzodiazepines as feed intake enhancers and non-steroidal anti-inflammatory drugs (NSAIDs) as pale meat-making agents. Several non-traditional substances are suspected to be used in the field of breeding animals. This is the case for growth hormones (GHs) and all substances acting over this anabolic compound, as for instance, orally GH secretagogue. Moreover, ecdysteroids, which according to old Russian studies, have anabolic activity, are actually very easy to purchase on the Internet. Recent findings in different classes of growth promoters are discussed in detail.

Targeting Plasmodium PI(4)K to eliminate malaria

Achieving the goal of malaria elimination will depend on targeting Plasmodium pathways essential across all life stages. Here we identify a lipid kinase, phosphatidylinositol-4-OH kinase (PI(4)K), as the target of imidazopyrazines, a new antimalarial compound class that inhibits the intracellular development of multiple Plasmodium species at each stage of infection in the vertebrate host. Imidazopyrazines demonstrate potent preventive, therapeutic, and transmission-blocking activity in rodent malaria models, are active against blood-stage field isolates of the major human pathogens P. falciparum and P. vivax, and inhibit liver-stage hypnozoites in the simian parasite P. cynomolgi. We show that imidazopyrazines exert their effect through inhibitory interaction with the ATP-binding pocket of PI(4)K, altering the intracellular distribution of phosphatidylinositol-4-phosphate. Collectively, our data define PI(4)K as a key Plasmodium vulnerability, opening up new avenues of target-based discovery to identify drugs with an ideal activity profile for the prevention, treatment and elimination of malaria.

Imidazo[1,2-a]quinoxalin-4-amines: A novel class of nonxanthine A1- adenosine receptor antagonists

The syntheses and A1 adenosine receptor affinities of a number of imidazo[1,2-a]quinoxalin-4-amines are reported. Structure-activity relationships within the series and in comparison with other similar tricyclic nonxanthine adenosine antagonists are discussed, leading to a putative common binding mode of these nitrogen-containing heterocycles to A1 adenosine receptors. Secondary amino compounds displayed the best affinities toward A1 receptors, while the tertiary amines were almost devoid of activity, thus suggesting a crucial role for the hydrogen bond-forming 4-NH group. Remarkably higher potencies for 1-methyl and N-cyclopentyl derivatives were also found. 4-Cyclopentylamino-1-methylimidazo[1,2-a]quinoxaline (IRFI 165) is the most potent compound in this series, having K(i)(A1) = 7.9 nM. It is also provided with a good A1 selectivity both versus A(2a) and A3 subtypes and was selected for further pharmacological studies.
