Abstract
Stereoselective inhibition aided by "tailor-made" polymeric additives is an efficient approach to obtain enantiopure compounds through conglomerate crystallization. The chemical and configurational match between the side groups of polymers and the molecules of undesired enantiomer is considered to be a necessary condition for successful stereoseparation. Whereas in this contribution, we present an effective resolution of chiral pharmaceuticals by using cellulose acetates as the additives, which stereoselectively reside on the specific crystal faces of one enantiomer and inhibit its crystal nucleation and growth through helical pattern and supramolecular interaction complementarity. An investigation of nimodipine serves as a case study to highlight the novelty of this strategy wherein R-crystals exhibiting an impressive enantiomeric excess value of 97 % can be attained by employing a mere 0.01 wt % cellulose acetate. Guaifenesin and phenyl lactic acid are also well-resolved by utilizing this methodology. Our work not only brings about a brand-new design strategy for "tailor-made" additives, but will also promote the further exploration of the endless potential for utilizing natural biomolecules in chiral recognition and resolution.

Abstract
The renewable 5-hydroxymethylfurfural (5-HMF) has gained a wide interest from the chemistry community as a valuable biobased platform opening the way to many applications. Despite an impressive number of publications reporting either its preparation or its functionalization, its direct use in fine chemistry, and especially in multi-component reaction (MCR), is less reported. Here, we report a complete study of the use of 5-HMF in the Hantzsch dihydropyridines synthesis. The strategy was applied to a scope of β-dicarbonyl molecules (including β-ketoesters and 1,3-diketones) in a 3-component procedure leading to a series of symmetrical 1,4-dihydropyridines derived from 5-HMF in excellent yields. The study was extended to the 4-component protocol using one equivalent of a β-ketoester and one equivalent of 5,5-dimethyl-1,3-cyclohexanedione (dimedone), which efficiently provided the corresponding unsymmetrical dihydropyridines.

Abstract
The building of heterocyclic systems containing hydrogenated fragments is an important step towards the creation of biologically-active compounds with a wide spectrum of pharmacological activity. Among the numerous methods for creating such systems, a special place is occupied by processes using N-substituted maleimides as the initial substrate. This molecule easily reacts in Diels-Alder/retro-Diels-Alder reactions, Michael additions with various nucleophiles, and co-polymerization processes, as have been described in numerous detailed reviews. However, information on the use of maleimides in cascade heterocyclization reactions is currently limited. This study is devoted to a review and analysis of existing literature data on the processes of recyclization of N-substituted maleimides with various C,N-/N,N-/S,N-di- and polynucleophilic agents, such as amidines, guanidines, diamines, aliphatic ketazines, aminouracils, amino- and mercaptoazoles, aminothiourea, and thiocarbomoyl pyrazolines, among others. The significant structural diversity of the recyclization products described in this study illustrates the powerful potential of maleimides as a building block in the organic synthesis of biologically-active compounds with hydrogenated heterocyclic fragments.

Abstract
The annulation of N-cyclopropyl enamines to produce 1,4-dihydropyridine (1,4-DHP) derivatives is described. In the presence of molecular iodine (I2), an N-cyclopropyl enamine substrate undergoes iodination, opening of the cyclopropyl ring, and annulation with a second molecule of the substrate to form the 1,4-DHP product. This reaction is amenable to gram-scale operations under mild reaction conditions with no transition metals being required. Further transformations of the 1,4-DHPs leads to related pyridine and bicyclic frameworks.

Abstract
Yoshinone A was derived from marine algae and shown to inhibit adipogenic differentiation. The natural compound is composed of a γ-pyrone ring and a side chain and that contains two asymmetric carbons. Although their absolute configuration has been determined, there is no information available on the stereoisomers and their bioactivities. To address this question, we synthesized all four stereoisomers and measured their activities. We also prepared three more derivatives of yoshinone A and found that the stereo-configuration inside the side chain, the γ-pyrone ring, and bulkiness of the side chain all played important roles in its activity. Our findings should help to elucidate the mechanism of action of yoshinone A.

Abstract
Polyhydroquinolines were efficiently obtained from a sequential four-component reaction between dimedone or 1,3-cyclohexandione, ethyl acetoacetate, or methyl acetoacetate as a β-ketoester, aldehydes, and ammonium acetate, under the catalysis of Mo@GAA-Fe3O4 MNPs as a green, effective, recyclable, and environmentally friendly nanocatalyst. Due to its magnetic nature the prepared catalyst can be easily separated from the reaction mixture by an external magnet and reused several times without significant changes in catalytic activity and reaction efficiency. The catalyst was characterized using energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), vibrating sample magnetometry (VSM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM).

Abstract
Heteroatoms as well as heterocyclic scaffolds are frequently present as the common cores in a plethora of active pharmaceuticals natural products. Statistically, more than 85% of all biologically active compounds are heterocycles or comprise a heterocycle and most frequently, nitrogen heterocycles as a backbone in their complex structures. These facts disclose and emphasize the vital role of heterocycles in modern drug design and drug discovery. In this review, we try to present a comprehensive overview of top prescribed drugs containing nitrogen heterocycles, describing their pharmacological properties, medical applications and their selected synthetic pathways. It is worth mentioning that the reported examples are actually limited to current top selling drugs, being or containing N-heterocycles and their synthetic information has been extracted from both scientific journals and the wider patent literature.

Abstract
In this review, the recent synthetic approaches of amino hexahydroquinolines and their spirocyclic structures were highlighted. The synthetic routes include, two-components, three-components or fourcomponents reactions. The two-component [3+3] atom combination reaction represents the simplest method. It involves Michael addition of the electron rich β-carbon of β-enaminones to the activated double bond of cinnamonitriles followed by cyclization to yield hexahydroquinoline compounds. The bioactivity profiles and SAR studies of these compounds were also reviewed with emphasis to the utility of these substances as antimicrobial, anticancer and antitubercular agents, as well as calcium channel modulators.

Abstract
An eco-friendly and cost-effective, microwave-assisted green approach has been developed for the synthesis of diverse functionalized N-methyl-1,4-dihydropyridines (1,4-DHPs). This pseudo three-component reaction was carried out between two equivalents of (E)-N-methyl-1-(methylthio)-2-nitroethenamine (NMSM) and one equivalent of aromatic aldehydes under microwave irradiation at 100 °C without catalyst and solvent. Short reaction times, avoidance of toxic solvents or expensive, metallic and corrosive catalysts and no need for column chromatographic purification are among the valuable features of the presented method. Moreover, the “greenness” of the method was evaluated within the ambits of the defined green metrics such as atom economy, carbon efficiency, E-factor, reaction mass efficiency, overall efficiency, process mass intensity and solvent intensity and the method exhibited a good to excellent score.

Eight compounds in the present study exhibited single digit micromolar binding to this efflux transporter. One monomeric IDHP m-Br-1c, possessed submicromolar binding of 510nM at MDR-1. Three of the dimeric IDHPs possessed <1.5µM activity, and 4b and 4c were observed to have superior binding selectivity compared to their corresponding monomers verses the voltage gated calcium channel (VGCC). The dimer with the best combination of activity and selectivity for MDR-1 was analog 4c containing an m-Br phenyl moiety in the 3-position of the isoxazole, and a tether with five ethyleneoxy units, referred to herein as Isoxaquidar. Two important controls, mono-triazole 5 and pyridine 6, also were examined, indicating that the triazole - incorporated as part of the click assembly as a spacer - contributes to MDR-1 binding. Compounds were also assayed at the allosteric site of the mGluR5 receptor, as a GPCR 7TM control, indicating that the p-Br IDHPs 4d, 4e and 4f with tethers of from n=2 to 5 ethylenedioxy units, had sub-micromolar affinities with 4d being the most efficacious at 193nM at mGluR5. The results are interpreted using a docking study using a human ABC as our current working hypothesis, and suggest that the distinct SARs emerging for these three divergent classes of biomolecular targets may be tunable, and amenable to the development of further selectivity.

Abstract
Cellular signaling in both excitable and nonexcitable cells involves several classes of ion channels. Some of them are of minor importance, with very specialized roles in physiology, but here we concentrate on three major channel classes: TRP (transient receptor potential channels), voltage-gated sodium channels (Nav), and voltage-gated calcium channels (Cav). Here, we first propose a conceptual framework binding together all three classes of ion channels, a "flow-of-excitation model" that takes into account the inputs mediated by TRP and other similar channels, the outputs invariably provided by Cav channels, and the regenerative transmission of signals in the neural networks, for which Nav channels are responsible. We use this framework to examine the function, structure, and pharmacology of these channel classes both at cellular and also at whole-body physiological level. Building on that basis we go through the pathologies arising from the direct or indirect malfunction of the channels, utilizing ion channel defects, the channelopathies. The pharmacological interventions affecting these channels are numerous. Part of those are well-established treatments, like treatment of hypertension or some forms of epilepsy, but many other are deeply problematic due to poor drug specificity, ion channel diversity, and widespread expression of the channels in tissues other than those actually targeted.

Abstract
The association of the isoxazole and dihydropyridine (DHP) ring systems fused at the 4'-isoxazolyl- to the 4-position of the DHP has produced a combination scaffold, the isoxazolyl-DHPs (IDHPs) with unique conformational characteristics. The IDHPs are useful in probing biological activity, as exemplified by our efforts in the fields of voltage gated calcium channel (VGCC) antagonists and inhibitors of the multi-drug resistance (MDR) transporter. A strategically placed methyl group produced a signifcant change at the VGCC, with (R)-(+)-1-phenyl-prop-2-yl (3.7 nM) > phenethyl (22.9 nM) > (S)-(-)-1-phenyl-prop-2-yl (210 nM), a eudismic ratio of 56.7. Branching at the C-5 of the isoxazole produced a 25% increase in MDR binding, and replacing the DHP C-3 ester with a functionalized amide also gave a dramatic increase in binding affinity. Opportunities for combined scaffolds - including examples containing IDHPs - are waiting to be discovered: because new biology is driven by new chemistry.

Abstract
Three quinolone compounds were synthesized and crystallized in an effort to study the structure-activity relationship of these calcium-channel antagonists. In all three quinolones, viz. ethyl 4-(4-bromophenyl)-2,7,7-trimethyl-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carboxylate, (I), ethyl 4-(3-bromophenyl)-2,7,7-trimethyl-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carboxylate, (II), and ethyl 4-(2-bromophenyl)-2,7,7-trimethyl-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carboxylate, (III), all C21H24BrNO3, common structural features such as a flat boat conformation of the 1,4-dihydropyridine (1,4-DHP) ring, an envelope conformation of the fused cyclohexanone ring and a bromophenyl ring at the pseudo-axial position and orthogonal to the 1,4-DHP ring are retained. However, due to the different packing interactions in each compound, halogen bonds are observed in (I) and (III). Compound (III) crystallizes with two molecules in the asymmetric unit. All of the prepared derivatives satisfy the basic structural requirements to possess moderate activity as calcium-channel antagonists.

Abstract
Isoxazole-1,4-dihydropyridines (IDHPs) were tethered to fluorescent moieties using double activation via a lanthanide assisted Weinreb amidation. IDHP-fluorophore conjugate 3c exhibits the highest binding to date for IDHPs at the multidrug-resistance transporter (MDR-1), and IDHP-fluorophore conjugates 3c and 7 distribute selectively in SH-SY5Y cells. A homology model for IDHP binding at MDR-1 is presented which represents our current working hypothesis.

Abstract
AIM To examine the efficacy of YuanHu painkillers (YHP) as a treatment for primary dysmenorrhea and to reveal YHP's principle formula. METHODS A Wistar rat uterine contraction model was utilized in this study. Rats were given 0.698g/kg YHP, 0.07g/kg tetrahydropalmatine (THP; YHP's main component), 0.02g/kg imperatorin (IMP), or THP+IMP (0.07+0.02g/kg) as polypharmacy (PG) by gavage. H&E staining and histopathological examination of the uteri tissue samples were performed. We then detected superoxide dismutase (SOD) and malondialdehyde (MDA), nitric oxide (NO), as well as inducible nitric oxide synthase (iNOS), i-κB, nuclear factor-κB (NF-κB), and cyclooxygenase-2 (COX-2) indices. RESULTS PG significantly inhibited the uterine contraction of the primary dysmenorrhea rat model (p<0.05), and was significantly different than single-agent therapy (p<0.05). Histopathological examination showed inflammation in the uteri of the control group which YHP and its main constitutes alleviated. THP significantly inhibited the contraction of isolated uteri caused by Ach, PGF2α and oxytocin in a concentration-dependent fashion. THP and IMP both significantly affected the levels of NO, activation of NF-κB, up-regulated the expression of i-κB and down-regulated the expression of both iNOS and COX-2. IMP obviously decreased the level of MDA and increased the activation of SOD (p<0.05). PG obviously improved all the parameters mentioned above (p<0.05). CONCLUSIONS YHP exerted protective effects on primary dysmenorrhea in rats and remarkably alleviated the severity of experimental primary dysmenorrhea. The combined strategy proved to be more effective than either THP or IMP alone and may have synergistic effects in combination in primary dysmenorrhea. Mechanisms that might account for the beneficial effects include abating oxidative stress, inhibiting over-inflammatory reaction, and alleviating the contraction of isolated rat uteri by inhibiting the influx of extracellular Ca(2+). Broad potential for future clinical practice is foreseeable.

Abstract
In the title molecule, C19H18F3N3O, the dihydropyridine and cyclohexene rings both adopt sofa conformations. The five essentially planar atoms of the dihydropyridine ring [maximum deviation = 0.039 (2) Å] form a dihedral angle of 88.19 (8)° with the benzene ring. The F atoms of the trifluoromethyl group were refined as disordered over two sets of sites in a 0.840 (3):0.160 (3) ratio. In the crystal, N—H⋯O and N—H⋯N hydrogen bonds link molecules into a two-dimensional network parallel to (100).
