Synthesis, antitumor activity, and mechanism of action of 6-acrylic phenethyl ester-2-pyranone derivatives

Based on the scaffolds of caffeic acid phenethyl ester (CAPE) as well as bioactive lactone-containing compounds, 6-acrylic phenethyl ester-2-pyranone derivatives were synthesized and evaluated against five tumor cell lines (HeLa, C6, MCF-7, A549, and HSC-2). Most of the new derivatives exhibited moderate to potent cytotoxic activity. Moreover, HeLa cell lines showed higher sensitivity to these compounds. In particular, compound 5o showed potent cytotoxic activity (IC50 = 0.50-3.45 muM) against the five cell lines. Further investigation on the mechanism of action showed that 5o induced apoptosis, arrested the cell cycle at G2/M phases in HeLa cells, and inhibited migration through disruption of the actin cytoskeleton. In addition, ADMET properties were also calculated in silico, and compound 5o showed good ADMET properties with good absorption, low hepatotoxicity, and good solubility, and thus, could easily be bound to carrier proteins, without inhibition of CYP2D6. A structure-activity relationship (SAR) analysis indicated that compounds with ortho-substitution on the benzene ring exhibited obviously increased cytotoxic potency. This study indicated that compound 5o is a promising compound as an antitumor agent.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of 1-(2-Hydroxyethyl)piperidine, you can also check out more blogs about3040-44-6

Removal of the pyridine directing group from alpha-substituted N-(pyridin-2-yl)piperidines obtained via directed Ru-catalyzed sp3 C-H functionalization

Two strategies, “hydrogenation-hydride reduction” and “quaternization-hydride reduction”, are reported that make use of mild reaction conditions (room temperature) to efficiently remove the N-pyridin-2-yl directing group from a diverse set of C-2-substituted piperidines that were synthesized through directed Ru-catalyzed sp3 C-H functionalization. The deprotected products are obtained in moderate to good overall yields irrespective of the strategy followed, indicating that both methods are generally equally effective. Only in the case of 2,6-disubstituted piperidines, could the “quaternization-hydride reduction” strategy not be used. The “hydrogenation-hydride reduction” protocol was successfully applied to trans- and cis-2-methyl-N-(pyridin-2-yl)-6-undecylpiperidine in a short synthetic route toward (¡À)-solenopsin A (trans diastereoisomer) and (¡À)-isosolenopsin A (cis diastereoisomer).

Animal models of obesity: Genetic aspects

Among the candidate genes that have been reviewed herein, adipsin, calcitonin, cholecystokinin, G(i)alpha and G(s) subunits of G proteins, insulin I and II, and lipoprotein lipase have all been mapped to specific chromosomes in mouse or rat or both. In none of these cases is the chromosomal location syntenic with murine obesity genes db (on chromosome 4), or ob (on chromosome 6). Thus, all of these genes that code for metabolic modulators that are altered in obese animals but not in lean animals can be ruled out as possible loci of the primary genetic defect, at least for the murine models of obesity. In the case of neuropeptide Y, growth hormone, glucose transporter GLUT-4, the insulin receptor, and glyceraldehyde-3-phosphate dehydrogenase, chromosomal mapping has not yet been reported. However, in each of these cases, the evidence available strongly argues against any one of these physiologic modulators as the likely site of the primary defect for any one of the obesity mutations. Rather, in all of these cases, regardless of whether or not the gene has been mapped, the evidence suggests that posttranscriptional and/or posttranslational processes are involved in bringing about the specific alterations in level or activity of the protein product that is seen in the obese animal. Often hormonal regulation is invoked as a possible explanation for the changes observed in gene expression. The hormones most commonly identified as having a mediating effect on the particular metabolic pathways involved are insulin and/or the adrenal glucocorticoids. Since in each of the obese mutants, circulating amounts of these hormones are elevated, severely so in the case of insulin, it would not be surprising to find that they influence the levels and activities of many protein products involved in a variety of central nervous system and peripheral metabolic pathways. Glucocorticoids are known to exert direct effects on gene expression; however, with respect to adipsin gene expression, a direct effect has not been found (142). Furthermore, insulin itself has been considered as a candidate for the genetic lesion in these animals and has been ruled out by chromosomal localization. Thus, while it may certainly prove to be the case that both insulin and glucocorticoids affect these systems in some way, their effects appear to be indirect. The work by Platt and colleagues (154) in transgenic mice provides the first evidence of signal transduction between an obese mutant allele and the promoter sequence for a gene that shows significantly altered expression in the obese animal. Future studies should reveal how obese mutations exert their influence on the expression of many other structural genes in a variety of tissues that undergo significant alterations in obesity. Current data suggest that the mutant allele, in this case db, may code for a regulatory element that can interact with promoter sequences to alter gene expression in a variety of tissues. In 1982, we proposed that the fa gene may exert its influence on a fundamental cellular regulatory function pleiotropically (201). Given the information now available on numerous candidate genes that have altered levels of expression in tissues ranging from specific hypothalamic brain regions to liver, pancreas, and adipose tissue, and given the ability to construct appropriate vectors for production of transgenic animals, investigators interested in understanding genetic obesity will be able to test similar hypotheses.

Palladium-mediated N-arylation of heterocyclic diamines: Insights into the origin of an unusual chemoselectivity

The chemoselectivity of the palladium-mediated reaction of bromobenzene with various heterocyclic diamines was studied. Whatever the ligand used, 3-aminopyrrolidine underwent arylation of the secondary amine function (> 82%), whereas the more flexible 3-aminoazepinine was arylated on its primary function (>70%). The ratio “arylation of primary amine versus arylation of secondary amine” of 3-aminopiperidine with bromobenzene varied from 90:10 (BINAP, electron-enriched and hindered biphenyls L2 or L3) to 32:68 with the Josiphos-type ligand L10. The same trend was observed when 4-aminopiperidine was used (82:18 with L2 and 17:83 with L10). This selectivity can be tuned by the choice of aryl halide partners having different steric and electronic properties. A cooperative effect of both nitrogens of diamines during the reaction was deduced from competitive experiments. Finally, 13C and 31P NMR experiments, carried out with 3-aminopyrrolidine at room temperature, support a fast coordination of the primary amine to the metal. Indeed, a palladium complex resulting from the unusual displacement of one phosphane group of the intermediate ArPdX(BINAP) by the primary amino group was characterized.

SO2 effect on degradation of MEA and some other amines

SO2 is the main acidic impurity in flue gas and will affect amine degradation in CO2 capture process. This work introduced SO2/Na2SO3 in various experiment conditions of MEA (monoethanolamine) oxidative degradation and evaluated the SO2 effect on MEA degradation considering both oxidative and thermal degradation. 60 ppm SO2 could inhibit MEA oxidative degradation by scavenging oxidative radicals in absorber condition. Higher concentration of SO2 does not enhance the inhibitory effect, but will increase the corrosivity of the solution. NH3 is promoted by sulfite and becomes significant in MEA thermal degradation. Thiosulfate, the disproportionation product of sulfite, is believed to be the catalyst of SN2 reaction. Na 2SO3 was used to test SO2-3 effect on thermal degradation of EDA (ethylenediamine), 2-PE (2-piperidineethanol) and PZ/AMP (piperazine /2-amino-2-methyl-1-propanol) solution. Alkyl structure of amines has important effect on the SN2 reactions.

(Pyridylcyanomethyl)piperazines as orally active PAF antagonists

A series of (pyridylcyanomethyl)piperazines was prepared and evaluated for PAF-antagonist activity. Compounds were tested in vitro in a PAF-induced platelet aggregation assay and in vivo in a PAF-induced hypotension test in normotensive rats. Oral activity was ascertained through a PAF-induced mortality test in mice. The main structure-activity trends of the series were established. Activity was mainly found in four skeletons: 1-acyl-4-(3- pyridylcyanomethyl)-piperazine, 1-acyl-4-(4-pyridylcyanomethyl)piperazine, 1- acyl-4-(3-pyridylcyanomethyl)piperidine, and 1-acyl-4-cyano-4-(3- pyridylamino)piperidine. The acyl substituents, diphenylacetyl and 3,3- diphenylpropionyl, provided the most active compounds, and the introduction of an amine or hydroxy group in the 3,3-diphenylpropionyl substituent led to further improvement in oral activity. As a result, three of the most active compounds (100, 114, and 115) have been selected for further pharmacological development.

Alkoxycarbonylpiperidines as N-nucleophiles in the palladium-catalyzed aminocarbonylation

Piperidines possessing ester functionality, such as 2-(methoxycarbonyl) piperidine (methyl pipecolinate), 3-(ethoxycarbonyl)piperidine (ethyl nipecotate), and 4-(ethoxycarbonyl)piperidine (ethyl isonipecotate), were used as N-nucleophiles in palladium-catalyzed aminocarbonylation of iodobenzene and iodoalkenes such as 1-iodocyclohexene and 17-iodoandrost-16-ene. While the aminocarbonylation of both iodoalkenes, carried out under mild reaction conditions, resulted in the exclusive formation of the carboxamide, the same reaction of iodobenzene brought about the mixture of the corresponding carboxamide and 2-ketocarboxamide. The chemoselectivity toward the latter compounds, formed via double carbonyl insertion, was substantially increased by using high carbon monoxide pressure (up to 40 bar). Carboxamides derived from iodoalkenes and ketocarboxamides derived from iodoarene have been obtained in moderate to high yields. Graphical abstract: [Figure not available: see fulltext.]
