Design, synthesis, and biological evaluation of novel 4-alkylamino-1- hydroxymethylimidazo[1,2-a]quinoxalines as adenosine A1 receptor antagonists

The preparation and biological evaluation of a series of 4-alkylamino-1-hydroxymethylimidazo[1,2-a]quinoxalines as adenosine A 1 receptor antagonists are described. 4-Cyclopentylamino-7,8- dichloro-1-hydroxymethylimidazo[1,2-a]quinoxaline shows potent adenosine A 1 receptor inhibitory activity, having Ki = 7 nM. A series of 4-alkylamino-1-hydroxymethylimidazo[1,2-a]quinoxalines have been synthesized and evaluated for their adenosine A1 receptor inhibitory activity in the radioligand binding assays. The compounds were tested for the inhibition percent (IP) and the affinity toward A1AR (Ki) that IP were more than 90% in the nanomolar range. 4-Cyclopentylamino-7,8-dichloro-1- hydroxymethylimidazo[1,2-a]quinoxaline 18 is the most potent compound in this series, having Ki = 7 nM, which is remarkably higher than that of IRFI-165 (Ki = 48). 1-Hydroxymethyl groups of the tricyclic heteroarmatic compounds displayed the potent affinities toward A1AR.

Herein, we report a mild protocol for metal-, photocatalyst-, and light-free Minisci C-H alkylation reactions of N-heteroarenes with alkyl oxalates derived from primary, secondary, and tertiary alcohols. The protocol uses environmentally benign persulfate as a stoichiometric oxidant and does not require high temperatures or large excesses of either of the substrates, making the procedure suitable for late-stage C-H alkylation of complex molecules.

Microwave-Assisted Synthesis of (Piperidin-1-yl)quinolin-3-yl)methylene)hydrazinecarbothioamides as Potent Inhibitors of Cholinesterases: A Biochemical and In Silico Approach

Alzheimer’s disease (AD), a progressive neurodegenerative disorder, characterized by central cognitive dysfunction, memory loss, and intellectual decline poses a major public health problem affecting millions of people around the globe. Despite several clinically approved drugs and development of anti-Alzheimer’s heterocyclic structural leads, the treatment of AD requires safer hybrid therapeutics with characteristic structural and biochemical properties. In this endeavor, we herein report a microwave-assisted synthesis of a library of quinoline thiosemicarbazones endowed with a piperidine moiety, achieved via the condensation of 6/8-methyl-2-(piperidin-1-yl)quinoline-3-carbaldehydes and (un)substituted thiosemicarbazides. The target N-heterocyclic products were isolated in excellent yields. The structures of all the synthesized compounds were fully established using readily available spectroscopic techniques (FTIR, H-1- and C-13-NMR). Anti-Alzheimer potential of the synthesized heterocyclic compounds was evaluated using acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes. The in vitro biochemical assay results revealed several compounds as potent inhibitors of both enzymes. Among them, five compounds exhibited IC50 values less than 20 mu M. N-(3-chlorophenyl)-2-((8-methyl-2-(piperidin-1-yl)quinolin-3-yl)methylene)hydrazine carbothioamide emerged as the most potent dual inhibitor of AChE and BChE with IC50 values of 9.68 and 11.59 mu M, respectively. Various informative structure-activity relationship (SAR) analyses were also concluded indicating the critical role of substitution pattern on the inhibitory efficacy of the tested derivatives. In vitro results were further validated through molecular docking analysis where interactive behavior of the potent inhibitors within the active pocket of enzymes was established. Quinoline thiosemicarbazones were also tested for their cytotoxicity using MTT assay against HepG2 cells. Among the 26 novel compounds, there were five cytotoxical and 18 showed proliferative properties.

Chiral Pd-Catalyzed Enantioselective Syntheses of Various N-C Axially Chiral Compounds and Their Synthetic Applications

Biaryl atropisomers are key structural components in chiral ligands, chiral functional materials, natural products, and bioactive compounds, and their asymmetric syntheses have been reported by many groups. In contrast, although the scientific community has long been aware of atropisomers due to rotational restriction around N-C bonds, they have attracted scant attention and have remained an unexplored research area. In particular, their catalytic asymmetric synthesis and the synthetic applications were unknown until recently. This Account describes studies conducted by our group on the catalytic enantioselective syntheses of N-C axially chiral compounds and their applications in asymmetric reactions. In the presence of a chiral Pd catalyst, the reactions of achiral secondary ortho-tert-butylanilides with 4-iodonitrobenzene proceeded in a highly enantioselective manner (up to 96% ee), affording N-C axially chiral N-arylated ortho-tert-butylanilides in good yields. The application of the present chiral Pd-catalyzed N-arylation reaction to an intramolecular version gave N-C axially chiral lactams with high optical purity (up to 98% ee). These reactions were the first highly enantioselective syntheses of N-C axially chiral compounds with a chiral catalyst. Since the publication of these reactions, N-C axially chiral compounds have been widely accepted as new target molecules for catalytic asymmetric reactions. Furthermore, chiral-Pd-catalyzed intramolecular N-arylations were applied to the enantioselective syntheses of N-C axially chiral quinoline-4-one and phenanthridin-6-one derivatives. We also succeeded in the enantioselective syntheses of various N-C axially chiral compounds using other chiral Pd-catalyzed reactions. That is, optically active N-C axially chiral N-(2-tert-butylphenyl)indoles, 3-(2-bromophenyl)quinazolin-4-ones, and N-(2-tert-butylphenypsulfonamides were obtained through chiral Pd-catalyzed 5-endo-hydroaminocyclization, monohydrodebromination (reductive asymmetric desymmetrization), and Tsuji-Trost N-allylation, respectively. The study of the catalytic asymmetric synthesis of axially chiral indoles has contributed to the development of not only N-C axially chiral chemistry but also the chemistry of axially chiral indoles. Subsequently, the catalytic asymmetric syntheses of various indole derivatives bearing a C-C chiral axis as well as an N-C chiral axis have been reported by many groups. Moreover, axially chiral quinazlolin-4-one derivatives, which were obtained through chiral Pd-catalyzed asymmetric desymmetrization, are pharmaceutically attractive compounds; for example, 2-methyl-3-(2-bromophenyl)quinazolin-4-one product is a mebroqualone possessing GABA agonist activity. Most of the N-C axially chiral products have satisfactory rotational stability for synthetic applications, and their synthetic utility was also demonstrated through application to chiral enolate chemistry. That is, the reaction of various alkyl halides with the enolate prepared from the optically active anilide, lactam, and quinazolinone products proceeded with high diastereoselectivity by asymmetric induction due to the N-C axial chirality. At the present time, N-C axially chiral chemistry has become a popular research area, especially in synthetic organic chemistry, and original papers on the catalytic asymmetric syntheses of various N-C axially chiral compounds and their synthetic applications have been published.

Facile nucleophilic substitution of coordinated acetonitrile in trans-[PtCl4(NCMe)(PPh3)]

( )Despite the generally accepted inertness of platinum(IV) complexes towards nucleophilic substitution, the title compound promptly reacts with nucleophiles L (L = pyridine, quinoline, isoquinoline, benzothiazole, o-, m-, ptoluidine) affording the corresponding acetonitrile substitution products. To follow the reaction spectroscopically, a series of platinum(IV) standards were prepared by bridge splitting of trans-[Pt(mu-Cl)Cl(PPh3)](2), followed by oxidation by PhICl2. All the new platinum(II) and platinum(IV) complexes were fully characterized, and, in some cases, the structure was studied by single crystal X-ray diffraction. Even when protic o-, m- and p-toluidines were used, chemoselectivity towards substitution was observed, with addition products formed in less than 10% extent.
