An Ultrasound-assisted Nanocatalysis: Ag NPs/rGO Nanocomposite Catalyzed One-pot Diastereoselective Synthesis of Functionalized Tetrahydropyridines

Ag NPs decorated reduced graphene oxide (Ag NPs/rGO) composite was synthesized through one-pot protocol involving simultaneous reduction of GO and AgNO3 and characterized by X-ray diffraction, transmission electron microscope, scanning electron microscopy, ultraviolet-visible, Fourier transform infrared, Raman, CV, and energy dispersive X-ray analyses. Results indicated that Ag NPs (similar to 30 nm) were unvaryingly distributed onto the surface of rGO with good dispersion capability that usually lacks in Ag NPs alone. These nanocomposites were exploited to study their catalytic activities toward the one-pot diastereoselective synthesis of functionalized tetrahydropyridines under ultrasonic irradiation (US). The catalytic activity of Ag NPs/rGO was about 22-fold higher under US as compared to conventional method. Antiselectivity, shorter reaction time, excellent yields, simple work-up procedure, and purification of products by non-chromatographic methods were inherent advantages of the protocol. The catalyst was reused up to four runs without an appreciable loss of catalytic activity. [GRAPHICS] .

Preclinical in vitro and in vivo pharmacokinetic properties of danicamtiv, a new targeted myosin activator for the treatment of dilated cardiomyopathy

Dilated cardiomyopathy (DCM) is a disease of the myocardium defined by left ventricular enlargement and systolic dysfunction leading to heart failure. Danicamtiv, a new targeted myosin activator designed for the treatment of DCM, was characterised in in vitro and in vivo preclinical studies. Danicamtiv human hepatic clearance was predicted to be 0.5 mL/min/kg from in vitro metabolic stability studies in human hepatocytes. For human, plasma protein binding was moderate with a fraction unbound of 0.16, whole blood-to-plasma partitioning ratio was 0.8, and danicamtiv showed high permeability and no efflux in a Caco-2 cell line. Danicamtiv metabolism pathways in vitro included CYP-mediated amide-cleavage, N-demethylation, as well as isoxazole- and piperidine-ring-opening. Danicamtiv clearance in vivo was low across species with 15.5, 15.3, 1.6, and 5.7 mL/min/kg in mouse, rat, dog, and monkey, respectively. Volume of distribution ranged from 0.24 L/kg in mouse to 1.7 L/kg in rat. Oral bioavailability ranged from 26% in mouse to 108% in dog. Simple allometric scaling prediction of human plasma clearance, volume of distribution, and half-life was 0.64 mL/min/kg, 0.98 L/kg, and 17.7 h, respectively. Danicamtiv preclinical attributes and predicted human pharmacokinetics supported advancement toward clinical development.

Recent Advances in the Synthesis of Piperidines: Functionalization of Preexisting Ring Systems

The present review focuses on strategies for the construction of piperidines which have appeared in the literature since 2003 through mid-2017. In a preceding chapter (201 /AFIE 191), we summarized synthetic methods involving the construction of the piperidine ring from essentially acyclic starting materials in an intra- or intermolecular manner. The present chapter aims at giving a general overview of decoration or modification of previously generated pyridines or piperidines. The hydrogenation of preformed pyridine or pyridinium rings and introduction of substituents into fully saturated piperidines as well as ring expansion of pyrrolidines to piperidines are the most prevalent methods.

New insight into the thermal-oxidative stability of polyamide 6: A comparison investigation on the effect of hindered amine and CuI/KI

Polyamide 6 (PA6) and stabilized PA6 with two different thermal stabilizers, (ie, metal salts CuI/KI and hindered amine KYN818 [1,3-benzendicarboxamide,N,N’-bis(2,2,6,6-tetramethyl-4-piperidinyl)]) were separately prepared by melt blending and then aged for different time. The effects of aging temperature and aging time on crystallization behaviors of PA6 and stabilized PA6 were systematically investigated by differential scanning calorimetry and X-ray diffraction. The variations of melting temperature, crystallinity and 2 theta values suggest that aging under high temperature will accelerate the formation of crystals initially and then the degradation of molecular chains. The yellowness index and maximum decomposition temperature of stabilized PA6 are higher than that of PA6, which is dominated by different aging mechanisms and properties of stabilizers. In addition, the viscosity of all systems is increased at the preliminary stage, which is caused by the crosslinking network and the post-polycondensation. The results of dynamic mechanical analysis showed that the glass transition temperature (T-g) decreases because the degradation of molecular chains during the aging process. Moreover, the carbonyl index for stabilized PA6 is lower than PA6, indicating the degradation is hindered by stabilizers. A comparison of the stabilization performance between CuI/KI and KYN818 was investigated to differentiate the long-term stabilizing efficiency.

X-ray Crystal Structure and Hirshfeld Analysis of Gem-Aminals-Based Morpholine, Pyrrolidine, and Piperidine Moieties

The gem-aminals of 1,2-dimorpholinoethane (1) and 1-morpholino-3-morpholinium bromide propane (2) were synthesized by reaction of two molar ratio of morpholine with the halogenating agents in the presence of basic condition (K2CO3) in acetone at room temperature (RT) overnight. The structures of the centro-symmetric compound 1 and the morpholinium salt derivative 2 were assigned unambiguous by single crystal X-ray diffraction analysis and compared with the 1,2-di(pyrrolidin-1-yl)ethane 3 and 1,2-di(piperidin-1-yl)ethane 4. The 1,2-dimorpholinoethane molecule has a center of symmetry at the midpoint of the C-C bond of the ethyl moiety leading to two equivalent halves. It crystallized in monoclinic crystal system and P2(1)/n space group, while the unit cell parameters are determined to be a = 6.0430(3), b = 8.0805(3), c = 11.1700(4) angstrom, and beta = 97.475(2)degrees with unit cell volume of 540.80(4) angstrom(3) and Z = 2 at 170(2) K. The less symmetric analogue 2 crystallized in the lower space group P2(1) with unit cell parameters of a = 6.37450(10), b = 11.1378(2), c = 9.6549(2) angstrom, and beta = 93.358(2)degrees, while the unit cell volume is 684.30(2)angstrom(3) at 120(2) K. Using Hirshfeld analysis, the molecules of 1 are mainly packed by weak N horizontal ellipsis H (4.2%), O horizontal ellipsis H (16.8%), and H horizontal ellipsis H (79.0%) interactions. In contrast, the molecules of 2 are packed by significantly short O horizontal ellipsis H (14.4%) and Br horizontal ellipsis H (11.6%) interactions in addition to the relatively long H horizontal ellipsis H (73.3%) interactions. DFT calculations predicted the molecular geometry of the studied compounds showing a good agreement with the experimental X-ray structures. Due to symmetry considerations, compounds 1, 3, and 4 are nonpolar with zero dipole moment, while the less symmetric molecule 2 has a dipole moment of 6.914 Debye. Their electronic aspects, such as natural population charges, HOMO, and LUMO energies as well as the corresponding reactivity descriptors, were also calculated and discussed.

Inverse agonism at serotonin and cannabinoid receptors

Contemporary receptor theory was developed to account for the existence of constitutive activity, as defined by the presence of receptor signaling in the absence of any ligand. In vitro studies with a variety of cell types have revealed the existence of constitutive activity and inverse agonism at a large number of receptors and also additional complexities of ligandreceptor interactions. Thus, ligands acting at a constitutively active receptor can act as agonists, antagonists, and/or inverse agonists, and these pharmacological characteristics can differ for an individual ligand depending upon the receptor response measured and the physiological state of the system under study. Studies with a variety of cell types have established that the serotonin 5-HT 2A and 5-HT2C receptors and the cannabinoid CB1 receptor demonstrate constitutive activity and inverse agonism in vitro. Serotonin and cannabinoid receptors are involved in a large number of physiological and behavioral functions. The possible existence of constitutive activity and inverse agonism at these receptors in vivo would provide new avenues for drug development. Recent studies have provided compelling evidence that both the serotonin 5-HT2A and 5-HT2C receptors and cannabinoid CB1 receptor demonstrate inverse agonism and constitutive activity also in vivo. This chapter describes our current knowledge of constitutive activity in vitro and then examines the evidence for constitutive activity in vivo.
