Identification of N-acylhydrazone derivatives as novel lactate dehydrogenase A inhibitors

Abstract Glycolysis is drastically increased in tumors and it is the main route to energy production with a minor use of oxidative phosphorylation. Among the key enzymes in the glycolytic process, LDH is emerging as one of the most interesting targets for the development of new inhibitors. In this context, in the present work, we carried out a virtual screening procedure followed by chemical modifications of the identified structures according to a “hit-to-lead” process. The effects of the new molecules were preliminary probed against purified human LDH-A. The compounds active at low micromolar level were additionally characterized for their activity on some cellular metabolic processes by using Raji human cell line. Within the series, 1 was considered the best candidate, and a more detailed characterization of its biological properties was performed. In Raji cells exposed to compound 1 we evidenced the occurrence of effects usually observed in cancer cells after LDH-A inhibition: reduced lactate production and NAD/NADH ratio, apoptosis. The flow cytometry analysis of treated cells also showed cell cycle changes compatible with effects exerted at the glycolytic level. Finally, in agreement with the data obtained with other inhibitors or by silencing LDH-A expression, compound 1 was found to increase Raji cells response to some commonly used chemotherapeutic agents. Taken together, all these finding are in support of the LDH-A inhibiting activity of compound 1.

A comparative reactivity survey of some prominent bisphosphine nickel(II) precatalysts in C-N cross-coupling

The synthesis and characterization of the new air-stable precatalyst (L1)Ni(o-tol)Cl (C1; where L1 = JosiPhos CyPF-Cy) is reported, along with the results of a comparative reactivity survey involving C1 and analogous PAd-DalPhos- and DPPF-containing precatalysts (C2 and C3, respectively) in representative nickel-catalyzed C(sp2)-N cross-coupling reactions. Precatalyst C1 was found to be competitive with, and in some cases complementary to, C2 in the monoarylation of ammonia and primary alkylamines with (hetero)aryl chlorides, including in otherwise challenging room temperature transformations. (Pseudo)halide comparison studies involving the cross-coupling of furfurylamine at room temperature revealed that in contrast to C2 precatalyst C1 performs less effectively with aryl bromides. Whereas C3 was found to be ineffective for such transformations, this DPPF-derived precatalyst proved superior to C1 and C2 in reactions involving the secondary dialkylamine test substrate morpholine.

Discovery of a new series of potent and selective linear tachykinin NK 2 receptor antagonists

Starting from 1 (MEN 14268), a selective tachykinin NK2 receptor antagonist with an interesting in vitro pharmacological profile, a family of numerous antagonists was obtained through an optimization process focused on iterated structural modifications. The effects of the introduction of a wide variety of substituents on the lipophilic aromatic part of the molecule and the modulation of the structural constraint through the insertion of different achiral alpha,alpha-dialkylamino acids were investigated. In particular, aromatic and benzofused heteroaromatic moieties were introduced at the pseudo-N-terminal residue to replace the 2-benzothiophene moiety, and a systematic investigation of the best positioning of substituents onto the aromatic platform was reported for the benzothiophene core. Studies on the modulation of the length and the rigidity of the hydrophilic pseudo-C-terminal pendant are presented. Many heteroaliphatic groups are well tolerated by the receptor in this part of the ligand. The product 48f (MEN15596), bearing a methyl substituent on the benzothiophene and a tetrahydropyranylmethylpiperidine pendant, was finally selected for its good in vivo activity after intravenous, intraduodenal, and oral administration in guinea pigs.

Ni-Catalyzed Suzuki-Miyaura Cross-Coupling of alpha-Oxo-vinylsulfones to Prepare C-Aryl Glycals and Acyclic Vinyl Ethers

We demonstrate that readily available and bench-stable alpha-oxo-vinylsulfones are competent electrophiles in Ni-catalyzed Suzuki-Miyaura cross-coupling reactions. The C-sulfone bond in the alpha-oxo-vinylsulfone motif is cleaved chemoselectively in these reactions, furnishing C-aryl glycals or acyclic vinyl ethers in high yields. These reactions proceed under mild conditions and tolerate a remarkable scope of heterocycles and functional groups. Preliminary mechanistic studies revealed the importance of an alpha-heteroatom in facilitating these transformations.

Abiotic oxidation of petroleum bitumens under natural conditions

Five series of crude oil samples exposed to atmospheric conditions have been analysed at the molecular level, each series comprising several samples originating from the same crude oil but altered to different extents. The aim of our investigation was to compare the specific impact of abiotic oxidation to other alteration processes such as biodegradation, evaporation and water washing. Bulk analyses revealed that increasing alteration is accompanied by an increase in oxygen content which parallels a relative increase of the proportions, as well as of the molecular weights of the macromolecular constituents of the bitumens. Gas chromatographic-mass spectrometric analyses of polar fractions showed the presence of oxygen-containing compounds (steroid ketones, benzothiophenic acids and sulfones) which result from oxidation of petroleum lipids. The hypothesis that part of these oxygenated compounds results from abiotic oxidation processes rather than from biodegradation is supported, notably, by the fact that oxygen incorporation generally occurred without any diastereomeric discrimination. This is also supported by simulation experiments performed on petroleum lipids, which showed that abiotic oxidation induces cleavage reactions affecting C-C and C-S bonds which may intervene in the transformation of geomacromolecules in the environment by degradation (‘depolymerization’). Thus abiotic oxidation may play a major role in the fate of petroleum pollutants in the environment by transforming lipidic organic matter from petroleum into more water soluble and, therefore, more biodegradable constituents. However, these can be more toxic to the environment as the water-soluble fraction may be easily taken up by biota. (C) 2000 Elsevier Science Ltd.

Evolution of products in the combustion of scrap tires in a horizontal, laboratory scale reactor

A horizontal laboratory reactor was used to study the evolution of byproducts from the combustion of scrap tires at five nominal temperatures (ranging from 650 to 1050 C) and different oxygen:sample ratios A model was used to calculate the bulk air ratio (lambda), and the oxygen consumption was discussed considering this ratio lambda. More than 100 volatile and semivolatile compounds were identified and quantified by gas chromatography mass spectrometry, plotting their yields vs the bulk air ratio and temperature. Five different behaviors considering the bulk air ratio and the temperature were identified.
