Catalytic Asymmetric Darzens and Aza-Darzens Reactions for the Synthesis of Chiral Epoxides and Aziridines

This review presents an overview on the recent advances in the catalytic enantioselective Darzens and aza-Darzens reactions for the synthesis of enantiopure three-membered oxygen and nitrogen containing heterocycles. Since the synthesis of epoxides is the most widely explored, compared to their nitrogen counterparts, particularly true when asymmetric synthesis are considered, in the last decades several methodologies have appeared or improved and are now available for the preparation of aziridines in a highly stereo- and enantioselective manner. Catalytic asymmetric Darzens and aza-Darzens reaction constitute an important tool in modern organic chemistry, as there is an increased interest in bioactive natural products and pharmaceutical agents that contain these skeletons.

Novel amide and imidazole compounds as potent hematopoietic prostaglandin D-2 synthase inhibitors

In seeking novel and potent small molecule hematopoietic prostaglandin D-2 synthase (H-PGDS) inhibitors as potential therapies for PGD(2)-mediated diseases and conditions, we explored a series comprising multiple aryl/heteroaryl rings attached in a linear arrangement. Each compound incorporates an amide or imidazole linker between the pyrimidine or pyridine core ring and the tail ring system. We synthesized and screened twenty analogs by fluorescence polarization binding assay, thermal shift assay, glutathione S-transferase inhibition assay, and a cell-based assay measuring suppression of LPS-induced PGD(2) stimulation. Amide analogs show ten-fold greater shift in the thermal shift assay in the presence of glutathione (GSH) versus the same assay run in the absence of GSH. The imidazole analogs did not produce a significant change in thermal shift between the two assay conditions, suggesting a possible stabilization effect of the amide linker in the synthase-GSH-inhibitor complex. Imidazole analog 23, (KMN-010034) demonstrates superior potency across the in vitro assays and good in vitro metabolic stability in both human and guinea pig liver microsomes.

Synthesis, spectral characteristics and microbiological activity of benzanthrone derivatives and their Cu(II) complexes

Two benzanthrone derivatives with an amide group (B1 and B2) attached to the C-3 atom have been synthesized and characterized by different spectral methods. The basic photophysical characteristics were investigated in organic solvents of different polarity. A batochromic shift was observed in the transition from non-polar to polar media. The influence of copper ions on the intensity of fluorescence emission was investigated and a stable copper complex with compound B2 was isolated. Its chemical structure was characterized by electronic spectroscopy, IR and EPR spectroscopy. The stoichiometry of the isolated complex was found to be at a 1: 1 ligand-copper ratio. The microbiological activity of the newly synthesized compounds against gram positive and gram negative bacteria and yeast was examined. The copper complex enhanced the antibacterial activity compared to that of the ligand. (C) 2019 Elsevier B.V. All rights reserved.

Indium-Catalyzed Intramolecular Hydroamidation of Alkynes: An Exo-Dig Cyclization for the Synthesis of Pyranoquinolines through Post-Transformational Reaction

An efficient approach for the synthesis of pyranoquinolines through the indium-catalyzed activation of alkynes is reported. Intramolecular hydro-amidation alkynes can proceed through alkyne activation by indium(III) and then 6-exo-dig cyclization, leading to a fused pyran ring with high selectivity, high atom economy, and good to excellent yields. The cyclization was accomplished through the oxygen, not the nitrogen, of the amide functional group.

The endocannabinoid system – current implications for drug development

In this review, the state of the art for compounds affecting the endocannabinoid (eCB) system is described with a focus on the treatment of pain. Amongst directly acting CB receptor ligands, clinical experience with increment Delta(9)-tetrahydracannabinol and medical cannabis in chronic non-cancer pain indicates that there are differences between the benefits perceived by patients and the at best modest effect seen in meta-analyses of randomized controlled trials. The reason for this difference is not known but may involve differences in the type of patients that are recruited, the study conditions that are chosen and the degree to which biases such as reporting bias are operative. Other directly acting CB receptor ligands such as biased agonists and allosteric receptor modulators have not yet reached the clinic. Amongst indirectly acting compounds targeting the enzymes responsible for the synthesis and catabolism of the eCBs anandamide and 2-arachidonoylglycerol, fatty acid amide hydrolase (FAAH) inhibitors have been investigated clinically but were per se not useful for the treatment of pain, although they may be useful for the treatment of post-traumatic stress disorder and cannabis use disorder. Dual-acting compounds targeting this enzyme and other targets such as cyclooxygenase-2 or transient potential vanilloid receptor 1 may be a way forward for the treatment of pain.

Copper-ligand clusters dictate size of cyclized peptide formed during alkyne-azide cycloaddition on solid support

Peptide and peptidomimetic cyclization by copper-catalyzed alkyne-azide cycloaddition (CuAAC) reaction have been used to mimic disulfide bonds, alpha helices, amide bonds, and for one-bead-one-compound (OBOC) library development. A limited number of solid-supported CuAAC cyclization methods resulting in monomeric cyclic peptide formation have been reported for specific peptide sequences, but there exists no general study on monocyclic peptide formation using CuAAC cyclization. Since several cyclic peptides identified from an OBOC CuAAC cyclized library has been shown to have important biological applications, we discuss here an efficient method of alkyne-azide ‘click’ catalyzed monomeric cyclic peptide formation on a solid support. The reason behind the efficiency of the method is explored. CuAAC cyclization of a peptide sequence with azidolysine and propargylglycine is performed under various reaction conditions, with different catalysts, in the presence or absence of an organic base. The results indicate that piperidine plays a critical role in the reaction yield and monomeric cycle formation by coordinating to Cu and forming Cu-ligand clusters. A previously synthesized copper compound containing piperidine, [Cu4I4(pip)(4)], is found to catalyze the CuAAC cyclization of monomeric peptide effectively. The use of 1.5 equivalents of CuI and the use of DMF as solvent is found to give optimal CuAAC cyclized monomer yields. The effect of the peptide sequence and peptide length on monomer formation are also investigated by varying either parameter systemically. Peptide length is identified as the determining factor for whether the monomeric or dimeric cyclic peptide is the major product. For peptides with six, seven, or eight amino acids, the monomer is the major product from CuAAC cyclization. Longer and shorter peptides on cyclization show less monomer formation. CuAAC peptide cyclization of non-optimal peptide lengths such as pentamers is affected significantly by the amino acid sequence and give lower yields.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

The Design and Evaluation of an l-Dopa-Lazabemide Prodrug for the Treatment of Parkinson’s Disease

l-Dopa, the metabolic precursor of dopamine, is the treatment of choice for the symptomatic relief of the advanced stages of Parkinson’s disease. The oral bioavailability of l-dopa, however, is only about 10% to 30%, and less than 1% of the oral dose is estimated to reach the brain unchanged. l-Dopa’s physicochemical properties are responsible for its poor bioavailability, short half-life and the wide range of inter- and intrapatient variations of plasma levels. An l-dopa-lazabemide prodrug is proposed to overcome the problems associated with l-dopa absorption. Lazabemide is a monoamine oxidase (MAO)-B inhibitor, a class of compounds that slows the depletion of dopamine stores in Parkinson’s disease and elevates dopamine levels produced by exogenously administered l-dopa. l-Dopa was linked at the carboxylate with the primary aminyl functional group of lazabemide via an amide, a strategy which is anticipated to protect l-dopa against peripheral decarboxylation and possibly also enhance the membrane permeability of the prodrug. Selected physicochemical and biochemical properties of the prodrug were determined and included lipophilicity (logD), solubility, passive diffusion permeability, pK(a), chemical and metabolic stability as well as cytotoxicity. Although oral and i.p. treatment of mice with the prodrug did not result in enhanced striatal dopamine levels, 3,4-dihydroxyphenylacetic acid (DOPAC) levels were significantly depressed compared to saline, l-dopa and carbidopa/l-dopa treatment. Based on the results, further preclinical evaluation of the l-dopa-lazabemide prodrug should be undertaken with the aim of discovering prodrugs that may be advanced to the clinical stages of development.

Empirical Assessment and Reusability of an Eco-Friendly Amine-Functionalized SBA-15 Adsorbent for Aqueous Ivermectin

Ivermectin has efficacious broad-spectrum action against several human and veterinary endo-/ectoparasites. However, it is an emerging contaminant in water, causing serious concern to environmental health experts because of its toxicity/adverse ecological effects and increasing input. Currently, conventional water treatment methods are not designed to effectively eliminate it. Hence, amine moiety-grafted SBA-15 (SBA-15-NH2) was prepared, characterized, and evaluated for ivermectin adsorption from water as well as its reusability. Ivermectin adsorption data were analyzed with pseudo-first order, pseudo-second order, and intraparticle diffusion kinetic models, in addition to Langmuir and Freundlich adsorption isotherm models and the thermodynamics parameters evaluated. Characterization data revealed that the SBA-15 mesoporous structure was intact in SBA-15-NH2 with reduced surface areas and pore sizes. The SBA-15 characteristic hydroxyl group infrared broad band disappeared with the appearance of stronger amide-I band upon functionalization. In addition, SBA-15-NH2 has approximate to 22% less thermal stability than the SBA-15, while both materials exhibited intense X-ray diffraction peaks typical of well-organized pore structures with no significant distortion after functionalization. Ivermectin adsorption was rapid, and equilibrium was reached within 180 min. The pseudo-second order kinetic model fit the data better than the pseudo-first order one, suggesting electrostatic interaction as a removal mechanism, while the intraparticle diffusion model indicated that approximate to 80% ivermectin uptake occurred on the external surfaces. The process was pH- and concentration-dependent and exhibited higher adsorption at extreme pH conditions (pH values approximate to 3 and 11) and higher concentrations. The SBA-15-NH2 adsorption capacity is 536.2 mu g/g at 30 degrees C, while the concentration left in solution could be as low as 1 mu g/L. Adsorption isotherm models revealed that the process involves multiple reaction phenomena including monolayer, heterogeneous, and multilayer adsorption simultaneously. Adsorption was spontaneous but exothermic, and thus, it decreased at high ambient temperature. The SBA-15-NH2 adsorbent exhibited potential for reusability with about 15% loss in efficiency after 3 cycles of adsorption and desorption.

The endocannabinoid system: Novel targets for treating cancer induced bone pain

Treating Cancer-induced bone pain (CIBP) continues to be a major clinical challenge and underlying mechanisms of CIBP remain unclear. Recently, emerging body of evidence suggested the endocannabinoid system (ECS) may play essential roles in CIBP. Here, we summarized the current understanding of the antinociceptive mechanisms of endocannabinoids in CIBP and discussed the beneficial effects of endocannabinoid for CIBP treatment. Targeting nonselective cannabinoid 1 receptors or selective cannabinoid 2 receptors, and modulation of peripheral AEA and 2-AG, as well as the inhibition the function of fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL) have produced analgesic effects in animal models of CIBP. Management of ECS therefore appears to be a promising way for the treatment of CIBP in terms of efficacy and safety. Further clinical studies are encouraged to confirm the possible translation to humans of the very promising results already obtained in the preclinical studies.
