Synthesis of the HIF-2alpha translation inhibitor compound 76 via a Japp-Klingemann coupling

The Iliopoulos laboratory previously reported the discovery of compound 76, a small molecule HIF2alpha inhibitor. HIF2alpha activation is known to play a critical role in both von Hippel-Lindau (VHL) disease-related tumors and sporadic renal cell carcinoma (RCC). We required a facile and scalable synthetic route to confirm the structure, to investigate the biological properties of compound 76, and to perform structure activity relationship optimization studies. Herein, we report the straightforward synthesis of compound 76 and a preliminary investigation into the scope of the methods developed.

Construction of the Benzomesembrine Skeleton: Palladium(0)-Catalyzed Intermolecular Arylative Dearomatization of alpha-Naphthols and Subsequent Aza-Michael Reaction

A novel palladium(0)-catalyzed intermolecular arylative dearomatization of alpha-naphthols and subsequent aza-Michael reaction is described. Two adjacent stereocenters were constructed efficiently through consecutive arylative dearomatization and Michael addition reactions. By utilizing this method, structurally diverse benzomesembrine derivatives were synthesized with excellent yields and chemoselectivity. The benzomesembrine products were shown to undergo versatile functional-group transformations.

Ag(I)-C-H Activation Enables Near-Room-Temperature Direct alpha-Arylation of Benzo[ b]thiophenes

The first example of near-room-temperature alpha-arylation of benzo[b]thiophenes is reported. The discovery rests on the observation of a switch in alpha-/beta-regioselectivity at different loadings of Pd2(dba)3·CHCl3 in the coupling between benzo[b]thiophene and 4-iodotoluene. We show that this unprecedented regioselectivity switch is driven by a Ag(I)-mediated C-H activation at the alpha-C-H position, which becomes the dominant mode of reactivity at low concentrations of Pd. Competition experiments, kinetic studies, KIE, and D/H scrambling experiments have been carried out supporting this mechanism.

Aromatic and Antiaromatic Pathways in Triphyrin(2.1.1) Annelated with Benzo[b]heterocycles

Understanding of the aromatic properties and magnetically induced current densities of highly conjugated chromophores is important when designing molecules with strongly delocalized electronic structure. Linear extension of the triphyrin(2.1.1) skeleton with an annelated benzo[b]heterocycle fragment modifies the aromatic character by extending the electron delocalization pathway. Two-electron reduction leads to an antiaromatic triphyrin(2.1.1) ring and an aromatic benzo[b]heterocycle subunit. Current-density calculations provide detailed information about the observed pathways and their strengths.

Carboxamides vs. methanimines: Crystal structures, binding interactions, photophysical studies, and biological evaluation of (indazole-5-yl)methanimines as monoamine oxidase B and acetylcholinesterase inhibitors

A comprehensive study was performed for the first time to compare two structurally related substance classes, namely indazole-5-carboxamides (11?16) and (indazole-5-yl)methanimines (17?22). Both chemical entities are potent, selective and reversible MAO-B inhibitors and, therefore, may serve as promising lead structures for the development of drug candidates against Parkinson’s disease (PD) and other neurological disorders. Compounds 15 (Ki = 170 pM, SI = 25907) and 17 (Ki = 270 pM, SI = 16340) were the most potent and selective MAO-B inhibitors in both series. To investigate the multi-target inhibitory activity, all compounds were further screened for their potency against human AChE and BuChE enzymes. Compound 15 was found to be the most potent and selective AChE inhibitor in all series (hAChE IC50 = 78.3 ± 1.7 muM). Moreover, compounds 11 and 17 showed no risk of drug-induced hepatotoxicity and a wider safety window, as determined in preliminary cytotoxicity screening. Molecular modeling studies into the human MAO-B enzyme-binding site supported by a HYDE analysis suggested that the imine linker similarly contributes to the total binding energy in methanimines 17?22 as the amide spacer in their carboxamide analogs 11?16. Amplified photophysical evaluation of compounds 17 and 20, including single X-ray analysis, photochemical experiments, and quantum-chemical calculations, provided insights into their more favourable isomeric forms and structural features, which contribute to their biologically active form and promising drug-like properties.

Novel sulfoxide-introducing reaction and photochromic reactions of ethenylsulfinyl derivatives of dithienylethenes

New diarylethenes possessing one or two arenesulfinylethenyl moieties were casually synthesised. The photochromic and chiroptical properties of 1,2-bis-2-{2-methyl-5-[2-(4-toluenesulfinyl)ethenyl]-3- thienyl}-3,3,4,4,5,5-hexafluorocyclopentene were examined. While its colouring quantum yield by 313-nm irradiation (PhiO?C) was as large as 0.46, its bleaching quantum yield by 621-nm irradiation (PhiO?C) was negligibly small. Diels-Alder reaction of 2-(4-toluenesulfinyl)-1,4-benzoquinone with diarylethenes with the structure of 1-aryl-2-(5-ethenyl-2-methyl-3-thienyl)-3,3,4,4,5, 5-hexafluorocyclopentene gave, instead of the expected Diels-Alder cycloadduct or its derivatives, 1-aryl-2-{2-methyl-5- [2-(4-toluenesulfinyl)ethenyl]-3-thienyl}-3,3,4,4,5, 5-hexafluorocyclopentene.

Palladacycle-catalyzed phosphonation of aryl halides in neat water

An efficient and generally applicable protocol for the palladacycle- catalyzed arylation of diisopropyl H-phosphonate in water was developed. The remarkable features of this C-P bond-forming reaction include wide substrate scope including the inactive electron-rich and electron-neutral aryl chlorides, the weak inorganic base KF instead of strong bases such as KOtBu or NaOtBu for the activation of C-Cl bond, and the addition of isopropanol to avoid the decomposition of diisopropyl H-phosphonate.

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.
