Structure?activity relationship study of peptidomimetic aldehydes as enterovirus 71 3C protease inhibitors

A series of peptidomimetic aldehydes were designed, synthesized, and evaluated for their biochemical activity against 3C protease (3Cpro) and anti-enterovirus 71 (EV71) activity in?vitro. Molecular docking revealed that 5s (IC50?=?0.22?¡À?0.07?muM, EC50?=?0.18?¡À?0.05?muM) could bind well to the active site of EV71 3Cpro, which was consistent with the biological data compared to reference 5a (IC50?=?0.54?¡À?0.02?muM, EC50?=?0.26?¡À?0.07?muM). Structure and relationship study led to the discovery of aldehyde 5x (IC50?=?0.10?¡À?0.02?muM, EC50?=?0.11?¡À?0.07?muM), which exhibited the most potent 3Cproinhibitory and antiviral activity.

2,2?-Bis-substituted Biphenyls by the Addition of Nucleophiles to Benzyne Followed by in Situ Oxidative Homocoupling

The paper describes the addition of Mg-anilides and -thiolates to in situ generated benzyne with subsequent oxidative homocoupling of the adducts to give 2,2?-bis-substituted biphenyls in a one-pot process. Oxidative C-C bond formation was best achieved with a Cu catalyst using O2 as oxidant. The sequence comprises two C-X and one C-C bond formation and the products were obtained in moderate yields. Some of the 2,2?-bis-substituted biphenyls have been characterized by X-ray analysis.

Photolysis of (3-methyl-2H-azirin-2-yl)-phenylmethanone: Direct detection of a triplet vinylnitrene intermediate

The photoreactivity of (3-methyl-2H-azirin-2-yl)-phenylmethanone, 1, is wavelength-dependent (Singh et al. J. Am. Chem. Soc. 1972, 94, 1199-1206). Irradiation at short wavelengths yields 2P, whereas longer wavelengths produce 3P. Laser flash photolysis of 1 in acetonitrile using a 355 nm laser forms its triplet ketone (T1K, broad absorption with lambdamax ? 390-410 nm, tau ? 90 ns), which cleaves and yields triplet vinylnitrene 3 (broad absorption with lambdamax ? 380-400 nm, tau = 2 mus). Calculations (B3LYP/6-31+G(d)) reveal that T1K of 1 is located 67 kcal/mol above its ground state (S0) and has a long C-N bond (1.58 A), and the calculated transition state to form 3 is only 1 kcal/mol higher in energy than T1K of 1. The calculations show that 3 has significant 1,3-carbon iminyl biradical character, which explains why 3 reacts efficiently with oxygen and decays by intersystem crossing to the singlet surface. Photolysis of 1 in argon matrixes at 14 K produced ketene imine 7, which presumably is formed from 3 intersystem crossing to 7. In comparison, photolysis of 1 in methanol with a 266 nm laser produces mainly ylide 2 (lambdamax ? 380 nm, tau ? 6 mus, acetonitrile), which decays to form 2P. Ylide 2 is formed via singlet reactivity of 1, and calculations show that the first singlet excited state of the azirine chromophore (S1A) is located 113 kcal/mol above its S0 and that the singlet excited state of the ketone (S1K) is 85 kcal/mol. Furthermore, the transition state for cleaving the C-C bond in 1 to form 2 is located 49 kcal/mol above the S0of 1. Thus, we theorize that internal conversion of S1A to a vibrationally hot S0 of 1 forms 2, whereas intersystem crossing from S1K to T1K results in 3.

Adenosine monophosphate (AMP)-activated protein kinase: A new target for nutraceutical compounds

Adenosine monophosphate-activated protein kinase (AMPK) is an important energy sensor which is activated by increases in adenosine monophosphate (AMP)/adenosine triphosphate (ATP) ratio and/or adenosine diphosphate (ADP)/ATP ratio, and increases different metabolic pathways such as fatty acid oxidation, glucose transport and mitochondrial biogenesis. In this sense, AMPK maintains cellular energy homeostasis by induction of catabolism and inhibition of ATP-consuming biosynthetic pathways to preserve ATP levels. Several studies indicate a reduction of AMPK sensitivity to cellular stress during aging and this could impair the downstream signaling and the maintenance of the cellular energy balance and the stress resistance. However, several diseases have been related with an AMPK dysfunction. Alterations in AMPK signaling decrease mitochondrial biogenesis, increase cellular stress and induce inflammation, which are typical events of the aging process and have been associated to several pathological processes. In this sense, in the last few years AMPK has been identified as a very interesting target and different nutraceutical compounds are being studied for an interesting potential effect on AMPK induction. In this review, we will evaluate the interaction of the different nutraceutical compounds to induce the AMPK phosphorylation and the applications in diseases such as cancer, type II diabetes, neurodegenerative diseases or cardiovascular diseases.

Process for the preparation of 4-hydroxy-3-(5-methyl-3-isoxazolylcarbamoyl)-2-methyl-2H-1,2-benzothiazine 1,1-dioxide

An improved process for the preparation of 4-hydroxy-3-(5-methyl-3-isoxazolylcarbamoyl)-2-methyl-2H-1,2-benzothiazine 1,1-dioxide (I), a known anti-inflammatory agent, requires the use of specific proportions of reactants and carefully controlled reaction conditions. An alkali metal alkoxide, suspended in dimethylformamide is combined, with stirring, as rapidly as possible with a solution of alkyl 2,3-dihydro-3-oxo-1,2-benzisothiazole-2-acetate 1,1-dioxide (II) in dimethylformamide, while maining the internal reaction temperature within 15-30C. More than two but less than six moles of the alkoxide are used per mole of the alkyl 2,3-dihydro-3-oxo-1,2-benzisothiazole-2-acetate 1,1-dioxide (II). After all reactants have been combined, stirring is continued for a specific period of time and then the reaction mixture is acidified. Total elapsed time from initial combination of reactants to acidification is from 30 to 50 minutes. Acidification of the reaction mixture precipitates out alkyl 4-hydroxy-2H-1,2-benzothiazine-3-carboxylate 1,1-dioxide (III) in substantially pure form in high yields, without recrystallization. Product III is methylated on the sulfonamide nitrogen and reacted with 3-amino-5-methyl-isoxazole to obtain crude I. A further improvement in the process of the invention involves a more efficient method for purifying crude product I: the need for large quantities of dioxane solvent is obviated. After slurrying and washing, product I is solubilized in dilute alkali, and decolorized. After filtration and acidification pure product I in high yield is obtained. In addition to preparing the known anti-inflammatory agent (I), the initial reaction step of the invention wherein 2,3-dihydro-3-oxo-1,2-benzisothiazole-2-acetate, 1,1-dioxide (II) is rearranged to form alkyl 4-hydroxy-2H-1,2-benzothiazine-3-carboxylate 1,1-dioxide (III), may be used with particular advantage for the preparation of other useful benzothiazine derivatives.
