Flow hydrodediazoniation of aromatic heterocycles

Continuous flow processing was applied for the rapid replacement of an aromatic amino group with a hydride. The approach was applied to a range of aromatic heterocycles, confirming the wide scope and substituent-tolerance of the processes. Flow equipment was utilized and the process optimised to overcome the problematically-unstable intermediates that have restricted yields in previous studies relying on batch procedures. Various common organic solvents were investigated as potential hydride sources. The approach has allowed key structures, such as amino-pyrazoles and aminopyridines, to be deaminated in good yield using a purely organic-soluble system.

Heteroarylmethoxyphenylalkoxyiminoalkylcarboxylic acids as leukotriene biosynthesis inhibitors

A novel series of heteroarylmethoxyphenylalkoxyiminoalkylcarboxylic acids was studied as leukotriene biosynthesis inhibitors. A hypothesis of structure-activity optimization by insertion of an oxime moiety was investigated using REV-5901 as a starting point. A systematic structure- activity optimization showed that the spatial arrangement and stereochemistry of the oxime insertion unit proved to be important for inhibitory activity. The promising lead, S-(E)-11, inhibited LTB4 biosynthesis in the intact human neutrophil with IC50 of 8 nM and had superior oral activity in vivo, in a rat pleurisy model (ED50 = 0.14 mg/kg) and rat anaphylaxis model (ED50 = 0.13 mg/kg). In a model of lung inflammation, S-(E)-11 blocked LTE4 biosynthesis (ED50 of 0.1 mg/kg) and eosinophil influx (ED50 of 0.2 mg/kg). S-(E)-11 (A-93178) was selected for further preclinical evaluation.

NMR recognition studies of C¡¤G base pairs by new easily accessible heterobicyclic systems

Recognition of DNA duplexes by triplex forming oligonucleotides (TFO) is limited to DNA homopurine sequences. As a first step to overcome this limitation we report here NMR recognition studies of the C¡¤G base pair by new heterocyclic systems, derived from benzimidazole and benzoxazole units bearing an urea donor moiety, designed to bound to the 4-amino group of the cytosine and the O4- and N7-atoms of the guanosine bases, respectively.

Fragment-based design of 3-aminopyridine-derived amides as potent inhibitors of human nicotinamide phosphoribosyltransferase (NAMPT)

The fragment-based identification of two novel and potent biochemical inhibitors of the nicotinamide phosphoribosyltransferase (NAMPT) enzyme is described. These compounds (51 and 63) incorporate an amide moiety derived from 3-aminopyridine, and are thus structurally distinct from other known anti-NAMPT agents. Each exhibits potent inhibition of NAMPT biochemical activity (IC 50 = 19 and 15 nM, respectively) as well as robust antiproliferative properties in A2780 cell culture experiments (IC50 = 121 and 99 nM, respectively). However, additional biological studies indicate that only inhibitor 51 exerts its A2780 cell culture effects via a NAMPT-mediated mechanism. The crystal structures of both 51 and 63 in complex with NAMPT are also independently described.

Structure-activity relationships of phosphoinositide 3-kinase (PI3K)/mammalian target of rapamycin (mTOR) dual inhibitors: Investigations of various 6,5-heterocycles to improve metabolic stability

N-(6-(6-Chloro-5-(4-fluorophenylsulfonamido)pyridin-3-yl)benzo[d] thiazol-2-yl)acetamide (1) is a potent and efficacious inhibitor of PI3Kalpha and mTOR in vitro and in vivo. However, in hepatocyte and in vivo metabolism studies, 1 was found to undergo deacetylation on the 2-amino substituent of the benzothiazole. As an approach to reduce or eliminate this metabolic deacetylation, a variety of 6,5-heterocyclic analogues were examined as an alternative to the benzothiazole ring. Imidazopyridazine 10 was found to have similar in vitro potency and in vivo efficacy relative to 1, while only minimal amounts of the corresponding deacetylated metabolite of 10 were observed in hepatocytes.

Schisandrin B elicits the Keap1-Nrf2 defense system via carbene reactive metabolite which is less harmful to mice liver

Background: Schisandrin B (Sch B) a main active component of Schisandra chinensis, has been shown to act as a liver protectant via activation of the Nrf2 pathway. Nevertheless, it remains unclear whether its reactive metabolite is responsible for Nrf2 activation; also, the effects of its reactive metabolite on liver function are still unknown. Methods: The present study determined and identifed the carbene reactive metabolite of Sch B in human and mice liver microsomes. Its roles in activating Nrf2 pathway and modifying macromolecules were further explored in human liver microsomes. Moreover the potential cytotoxicity and hepatoxicity of carbene on HepG-2 and mice were also investigated. Results: In the present study, cytochromes P450 (CYP450s) metabolized Sch B to carbene reactive metabolite, which, with the potential to modify peptides, were identifed and observed in human and mice liver microsomes. Moreover, the relevance of carbene in Nrf2 activation was verifed by co-incubation in the presence of CYP450 inhibitors in HepG-2 cells, as well as by molecular docking study of carbene and Keap1. Additionally, the cytotoxicity of Sch B on HepG-2 cells was signifcantly aggravated by CYP450 inducer (with LD50 decreasing from 63 to 21 muM) and signifcantly alleviated by CYP450 inhibitor and glutathione (with LD50 increasing from 63 muM to 200 muM). Besides, after oral administration of mice with Sch B (25?100 mg/kg) for 21 days, only the highest dose induced mild hepatotoxicity, which was accompanied by increasing the aminotransferase activity and centri-lobular hepatocellular infltration of lymphocytes. In addition, upregulation of CYP450 activity; Nrf2, NQO-1, and GST expression; and glutathione level was observed in Sch B treatment groups. Conclusion: The present study revealed that CYP450s mediate the conversion of Sch B to carbene, which subsequently binds to Keap1 and elicits Nrf2 pathway, which could further increase the elimination of carbene and thus exhibit a less harmful effect on mice liver.
