The interaction of heteroaryl-acrylates and alanines with phenylalanine ammonia-lyase from parsley

Acrylic acids and alanines substituted with heteroaryl groups at the beta-position were synthesized and spectroscopically characterized (UV, HRMS, 1H NMR, and 13C NMR spectroscopy). The heteroaryl groups were furanyl, thiophenyl, benzofuranyl, and benzothiophenyl and contained the alanyl side chains either at the 2- or 3-positions. While the former are good substrates for phenylalanine ammonia lyase (PAL), the latter compounds are inhibitors. Exceptions are thiophen-3-yl-alanine, a moderate substrate and furan-3-yl-alanine, which is inert. Possible reasons for these exceptions are discussed. Starting from racemic het eroaryl-2-alanines their D-enantiomers were prepared by using a stereodestructive procedure. From the heteroaryl-2- acrylates, the L-enantiomers of the heteroaryl-2-alanines were prepared at high ammonia concentration. These results can be best explained by a Friedel – Crafts-type electrophilic attack at the aromatic part of the substrates as the initial step of the PAL reaction.

The effects of cosolvents on homogeneously and heterogeneously base-catalyzed methanolysis of sunflower oil

Homogeneously and heterogeneously base-catalyzed sunflower oil methanolysis was investigated without and with the presence of the cosolvents. In the former case, KOH and tetrahydrofuran (THF) were used as a catalyst and a cosolvent, respectively, and the reaction was performed at the reaction temperature of 10 C and the methanol-to-oil molar ratio of 6: 1. In the latter case, CaO and various organic solvents such as THF, n-hexane, dioxane, diethyl ether, triethanolamine, ethyl acetate and methyl ethyl ketone were employed as a solid catalyst and a cosolvent, respectively, and the reaction was carried out at the reaction temperature of 60 C and the methanol-to-oil molar ratio of 6: 1. The rate of KOH-catalyzed sunflower oil methanolysis increased with increasing the THF concentration up to 50% of the oil mass, which was due to the self-enhancement of the interfacial area as the result of decreasing the mean drop size. No effect of THF present at the concentration of 20% on the rate of CaO-catalyzed methanolysis was observed, but at higher THF concentrations, the reaction was delayed and the final fatty acid methyl esters (FAME) yield was decreased. Of all tested cosolvents, only n-hexane and THF slightly improved the methanolysis reaction in its initial period, triethanolamine and ethyl acetate had no effect, while diethyl ether, dioxane and methyl ethyl ketone negatively influenced the reaction rate and the FAME yield.

Further structure-activity relationships in the series of tropanyl esters endowed with potent antinociceptive activity

Several analogs of the alpha-tropanyl esters of 2-(4-chlorophenoxy)butyric acid (SM21) and 2-phenylthiobutyric acid (SM32), endowed with potent antinociceptive and cognition enhancing activity, were synthesized, aimed at obtaining more potent and safe drug candidates. Variation of the acyl moiety, as well as the conformational restriction of atropine to give the alpha-tropanyl ester of 2,3-dihydrobenzofurane-3-carboxylic acid (18), practically abolished activity. In the case of 18, the antimuscarinic activity was also severely affected by the conformation restrain. On the contrary, conformational restriction of phenoxybutyric and phenylthiobutyric acid derivatives to give the alpha-tropanyl ester of 2,3-dihydro-benzofurane-2-carboxylic acid and 2,3-dihydro-benzothiophene-2-carboxylic acid, afforded potent analgesic drugs that unfortunately were too toxic to be reliable drug candidates. A series of related esters of benzofurane-3-carboxylic acid and benzothiophene-3-carboxylic acid were also studied and found to be potent but toxic analgesics.

Synthesis and in vitro activity of N-benzyl-1-(2,3-dichlorophenyl)-1H- tetrazol-5-amine P2X7 antagonists

Synthesis and biological evaluation of a novel class of substituted N-benzyl-1-(2,3-dichlorophenyl)-1H-tetrazol-5-amine derivatives resulted in the identification of potent P2X7 antagonists. These compounds were assayed for activity at both the human and rat P2X7 receptors. On the benzyl moiety, a variety of functional groups were tolerated, including both electron-withdrawing and electron-donating substituents. Ortho-substitution on the benzyl group provided the greatest potency. The ortho-substituted analogs showed approximately 2.5-fold greater potency at human compared to rat P2X 7 receptors. Compounds 12 and 38 displayed hP2X7 pIC 50s >7.8 with less than 2-fold difference in potency at the rP2X7.

Antitumor agents. 284. new desmosdumotin B analogues with bicyclic B-ring as cytotoxic and antitubulin agents

We previously reported that the biological acti-vity of analogues of desmosdumotin B (1) was dramatically changed depending on the B-ring system. A naphthalene B-ring analogue 3 exerted potent in vitro activity against a diverse panel of human tumor cell lines with GI50 values of 0.8-2.1 muM. In contrast, 1 analogues with a phenyl B-ring showed unique selective activity against P-glycoprotein (P-gp) overexpressing multidrug resistant cell line. We have now prepared and evaluated 1 analogues with bicyclic or tricyclic aromatic B-ring systems as in vitro inhibitors of human cancer cell line proliferation. Among all synthesized derivatives, 21 with a benzo[b]thiophenyl B-ring was highly active, with GI50 values of 0.06-0.16 muM, and this activity was not influenced by overexpression of P-gp. Furthermore, 21 inhibited tubulin assembly in vitro with an IC50 value of 2.0 muM and colchicine binding by 78% as well as cellular microtubule polymerization and spindle formation.

Discovery of a promising agent IQZ23 for the treatment of obesity and related metabolic disorders

Discovery of novel anti-obesity agents is a challenging and promising research area. Based on our previous works, we synthesized 40 novel beta-indoloquinazoline analogues by altering the skeleton and introducing preferential side chains, evaluated their lipid-lowering activity and summarized the structure-activity relationships. In combination with an evaluation of the lipid-lowering efficacies, AMP-dependent activated protein kinase (AMPK) activating ability and liver microsomal stability, compound 23 (named as IQZ23) was selected for further studies. IQZ23 exerted a high efficacy in decreasing the triglyceride level (EC50 = 0.033 muM) in 3T3-L1 adipocytes. Mechanistic studies revealed the lipid-lowering activity of IQZ23 was dependent on the AMPK pathway by modulating ATP synthase activity. This activation was accompanied by mitochondrial biogenesis and oxidation capacity increased, and insulin sensitivity enhanced in pertinent cell models by various interventions. Correspondingly, IQZ23 (20 mg/kg, i.p.) treatment significantly reversed high fat and cholesterol diet (HFC)- induced body weight increases and accompanying clinical symptoms of obesity in mice but without indicative toxicity. These results indicate that IQZ23 could be a useful candidate for the treatment of obesity and related metabolic disorders.

Indole carboxylic acid esters of melampomagnolide B are potent anticancer agents against both hematological and solid tumor cells

A series of novel, heteroaryl carboxylic acid conjugates of the sesquiterpene melampomagnolide-B (MMB, 3) has been evaluated as antitumor agents against an NCI panel of 64 human hematopoetic and solid tumor cell lines. The indole-3-acrylic acid conjugate 7j and the indole-3-carboxylic acid conjugate 7k were found to be the most potent analogs in the series. Compounds 7j and 7k exhibited remarkable growth inhibition, with GI50 values in the range 0.03?0.30?muM and 0.04?0.28?muM, respectively, against the cell lines in the leukemia sub-panel, and GI50 values of 0.05?0.40?muM and 0.04?0.61?muM, respectively, against 90% of the solid tumor cell lines in the NCI panel. Compound 7a was particularly effective against the sub-panel of breast cancer cell lines with GI50 values in the range <0.01?0.30?muM. Compounds 7j, 7a and its water soluble analog 7p also exhibited potent anticancer activity against rat 9L-SF gliosarcoma cells in culture. Compound 7j was the most potent compound in the series in the M9-ENL1 AML cell assay with a lethal dose concentration EC50 value of 720?nM, and exhibited the greatest cytotoxicity against a collection of primary AML stem cell specimens, which included a specimen that was unresponsive to PTL, affording EC50 values in the range 0.33?1.0?muM in three out of four specimens. The results from this study provide further evidence that analogs of the sesquiterpene MMB can be designed to afford molecules with significantly improved anticancer activity. Thus, both 7j and 7k are considered potential lead molecules in the search for new anticancer agents that can be used as treatments for both hematopoetic and solid tumors.
