In vitro activity and preliminary toxicity of various diamidine compounds against Trypanosoma evansi

Trypanosoma evansi is an animal pathogenic protozoan, causing a wasting disease called Surra, which is broadly distributed in a wide range of mammalian hosts. Chemotherapy is the most efficient control method, which depends on four drugs. Unfortunately, with the appearance of resistance to these drugs, their effective use is threatened, emphasising a need to find new drugs. Diamidines bind to the minor groove of DNA at AT-rich sites and exert their anti-trypanosomal activity by inhibiting one or more DNA dependent enzymes or by directly impeding the transcription process.In total, 67 novel diamidine compounds were tested in vitro to determine activity against an animal pathogenic Chinese kinetoplastic T. evansi strain. In comparison, a human pathogenic Trypanosoma brucei rhodesiense strain and a P2 transporter knock out of a Trypanosoma brucei brucei strain were also tested. All diamidine compounds tested in this study against T. evansi produced inhibitory concentration (IC50) values below 50nM. The results demonstrate that these compounds are highly active against T. evansi in vitro. In addition, preliminary in vivo toxicity tests were performed on all 67 diamidines with 69% of the compounds showing no acute toxicity at an intra-peritoneal dose of 100mg/kg.

Synthesis of functionalized tetrasubstituted pyrazolyl heterocycles – A review

Heterocyclic chemistry constitutes an essential branch of organic chemistry and heterocycles are widely known to display an array of biological properties. Pyrazoles represent key structural motifs in heterocyclic chemistry and are present in a large number of biologically active molecules relevant to the pharmaceutical and agrochemical industries. Compounds incorporating the pyrazolyl structural unit are being developed in a wide variety of therapeutic areas including CNS, metabolic diseases, and oncology. The current review summarizes recent advances in the synthesis of tetrasubstituted pyrazoles. The contents are discussed in five sections: (a) 1,3-dipolar cycloadditions, (b) related 1,3-dipolar cycloadditions, (c) condensations, (d) allenylphosphonates, and (e) synthesis of fused pyrazole containing heterocycles.

Structures of reactive nitrenium ions: Time-resolved infrared laser flash photolysis and computational studies of substituted N-methyl-N-arylnitrenium ions

A series of para-substituted N-methyl-N-phenylnitrenium ions (N-(4-biphenylyl)-N-methylnitrenium ion, N-(4-chlorophenyl)-N-methylnitrenium ion, N-(4-methoxyphenyl)-N-methylnitrenium ion, and N-(4-methylphenyl)-N-methylnitrenium ion) were generated through photolysis of the appropriately substituted 1-aminopyridinium salt. Laser flash photolysis using UV – vis detection as well as photoproduct analysis verified that the expected nitrenium ions were formed cleanly and rapidly following photolysis. Laser flash photolysis with time-resolved infrared detection allowed for structural characterization of the nitrenium ions through observation of a symmetrical aromatic C=C stretch in the region 1580-1628 cm-1. The specific frequencies reflect the degree of quinoidal character present in each phenylnitrenium ion (i.e., the degree to which the nitrenium ion resembles a 4-iminocyclohexa-2,5-dienyl cation). The 4-methoxy derivative shows the highest frequency C=C stretch, indicating that this strongly pi-electron-donating substituent imparts more quinoidal character, and the 4-chloro derivative shows the lowest frequency C=C stretch, suggesting that it possesses the least quinoidal character. Quantum calculations using density functional theory (BPW91/cc-pVDZ) were carried out on the same nitrenium ions. The theoretically derived IR frequencies showed excellent quantitative agreement with the experiment. The computed structures show significant bond length alternation in the phenyl rings, shortened C-N bond lengths, and substantial positive charge delocalization into the phenyl rings. All of these effects are more pronounced with increasing pi-donating character of the ring substituent. Arylnitrenium ions are well described as 4-iminocyclohexa-2,5-dienyl cations.

Identification of 5-Substituted 2-Acylaminothiazoles That Activate Tat-Mediated Transcription in HIV-1 Latency Models

The persistent reservoir of cells latently infected with human immunodeficiency virus (HIV)-integrated proviral DNA necessitates lifelong suppressive antiretroviral therapy (ART). Epigenetic targeted compounds have shown promise as potential latency-reversing agents; however, these drugs have undesirable toxicity and lack specificity for HIV. We utilized a novel HEK293-derived FlpIn dual-reporter cell line, which quantifies specific HIV provirus reactivation (LTR promoter) relative to nonspecific host cell gene expression (CMV promoter), to identify the 5-substituted 2-acylaminothiazole hit class. Here, we describe the optimization of the hit class, defining the functionality necessary for HIV gene activation and for improving in vitro metabolism and solubility. The optimized compounds displayed enhanced HIV gene expression in HEK293 and Jurkat 10.6 latency cellular models and increased unspliced HIV RNA in resting CD4+ T cells isolated from HIV-infected individuals on ART, demonstrating the potential of the 2-acylaminothiazole class as latency-reversing agents.

Orexin research: patent news from 2016

Introduction: The orexin system consists of two G-protein-coupled receptors, orexin 1 and orexin 2 and two endogenous ligands, orexin A and orexin B. It is evolutionarily highly conserved. It is involved in the promotion of wakefulness as well as in anxiety and addictive disorders. In addition, its activation via the Ox1 receptor triggers apoptosis in several cancer cell lines. Dual orexin receptor antagonists are successfully used to treat primary insomnia. The major open questions are now related to the clinical validation of Ox1 selective antagonists. A strong rationale exists for orexin agonism in the treatment of narcolepsy with cataplexy. Areas covered: The patent applications from Thomson Reuters Integrity Database added in 2016 are summarized and discussed together with the most important findings published in the scientific literature. Expert opinion: The large number of patents shows the continuing interest in the orexin receptors as targets. The structural scope covered is narrow. Questions about novelty and inventiveness are evident. The additional information published on X-ray structures on both orexin receptors opens new ways of optimizing antagonists. It might also influence the efforts in the identification of orexin receptor agonists. Being potential treatments for narcolepsy with cataplexy.
