Exploring the dicationic gemini surfactant for the generation of mesopores: a step towards the construction of a hierarchical metal-organic framework

The present study demonstrates a soft-template-assisted synthesis route to the preparation of a hierarchical microporous-mesoporous Cu-BTC metal-organic framework. The supramolecular assembly of di-cationic quaternary ammonium structure-directing agents cooperatively interacts with Cu-BTC framework coordination layers via a weak electrostatic interaction and self-assemble to form a Cu-BTC framework containing a hierarchical system of mesopores interconnected with micropores. Pore-size distribution measurements revealed that the produced metal-organic framework has a bimodal pore-size distribution consisting of micropores and mesopores. Materials prepared with the di-cationic structure-directing agent and swelling agent 1,3,5-trimethyl benzene showed further improvement in the mesopore diameter. The hierarchical Cu-BTC framework demonstrated higher CO2 uptake capacity and better oxidation activity in reactions involving large molecules, when compared to the conventional Cu-BTC framework.

Rational design of new multitarget histamine H-3 receptor ligands as potential candidates for treatment of Alzheimer’s disease

Design and development of multitarget-directed ligands (MTDLs) has become a very important approach in the search of new therapies for Alzheimer’s disease (AD). In our present research, a number of xanthone derivatives were first designed using a pharmacophore model for histamine H-3 receptor (H3R) antagonists/inverse agonists, and virtual docking was then performed for the enzyme acetylcholinesterase. Next, 23 compounds were synthesised and evaluated in vitro for human H3R (hH(3)R) affinity and inhibitory activity on cholinesterases. Most of the target compounds showed hH(3)R affinities in nanomolar range and exhibited cholinesterase inhibitory activity with IC50 values in submicromolar range. Furthermore, the inhibitory effects of monoamine oxidases (MAO) A and B were investigated. The results showed low micromolar and selective human MAO B (hMAO B) inhibition. Two azepane derivatives, namely 23 (2-(5-(azepan-1-yl)pentyloxy)-9H-xanthen-9-one) and 25 (2-(5-(azepan-1-yl)pentyloxy)-7-chloro-9H-xanthen-9-one), were especially very promising and showed high affinity for hH(3)R (K-i = 170 nM and 100 nM respectively) and high inhibitory activity for acetylcholinesterase (IC50 = 180 nM and 136 nM respectively). Moreover, these compounds showed moderate inhibitory activity for butyrylcholinesterase (IC50 = 880 nM and 394 nM respectively) and hMAO B (IC50 = 775 nM and 897 nM respectively). Furthermore, molecular docking studies were performed for hH(3)R, human cholinesterases and hMAO B to describe the mode of interactions with these biological targets. Next, the two most promising compounds 23 and 25 were selected for in vivo studies. The results showed significant memory-enhancing effect of compound 23 in dizocilpine-induced amnesia in rats in two tests: step-through inhibitory avoidance paradigm (SIAP) and transfer latency paradigm time (TLPT). In addition, favourable analgesic effects of compound 23 were observed in neuropathic pain models. Therefore, compound 23 is a particularly promising structure for further design of new MTDLs for AD.

Voltammetric behaviour of the anticancer drug irinotecan and its metabolites in acetonitrile. Implications for electrochemical therapeutic drug monitoring

In this paper the voltammetric behaviour of the anticancer drug irinotecan (CPT-11), its injectable form in the clinical treatment regimen, irinotecan hydrochloride (CPT-11HCl), and its main metabolites (namely SN-38, SN-38G, APC, and NPC), and the natural chemical analogous camptothecin (CPT) were investigated in acetonitrile using a glassy carbon electrode (GCE), in view of developing an analytical protocol for the therapeutic drug monitoring (TDM) of CPT-11 in patients under chemotherapy regimens. Our results showed that all compounds provided rather complex cyclic voltammetric (CV) patterns in both the negative and positive potential regions. The overall results indicated that the processes recorded in the negative potential region at both GCE and Pt electrodes could be hardly exploited for TDM applications, because of the overlapping of the peaks. Instead, in the positive potential region, the oxidation of the piperidine moiety of CPT-11, which was obtained in CPT-11HCl acetonitrile solutions basified with Na2B4O7 (synthetic solutions), proved to be useful for irinotecan quantification, as its process at the GCE took place over a potential region essentially free from interference. Preliminary differential pulse voltammetry (DPV) measurements performed in synthetic solutions of CPT-11HCl, over the concentration range 0.2-9 mu M, showed a linear dependence between peak current and concentration with a satisfactory correlation coefficient of 0.992. The reproducibility was within 5% from three replicates. (C) 2018 Elsevier Ltd. All rights reserved.

Citric Acid Catalyzed Aqua Mediated Multicomponent Synthesis of Tetrahydropyridines and its Antioxidant Activities

Tetrahydropyridine derivatives are one of the most demanding molecules due to its great applications in medicinal and synthetic chemistry. Here we have designed a new way to synthesize a series of tetrahydropyridine derivatives using citric acid. In this methodology, five-component reaction of 1,3-diketones, substituted amines and aldehydes is done in the presence of citric acid extracted from lemon juice. High atom economy, green and mild conditions, high to moderate yields and shorter reaction times were the key features of this methodology. Later, we have discussed the antioxidant activities of our compounds. It is observed that compound 4a, 4b, 4e, 4f, 4i and 4l were quite effective to show good antioxidant activity.

Octahydrocyclopenta[c]pyridine Scaffold – Enantioselective Synthesis and Indole Annulation

An optically active hexahydrocyclopenta[c]pyridine derivative with quaternary stereocenter was prepared as a new heterocyclic scaffold. Key reaction was the Pd-catalyzed asymmetric allylic alkylation of a piperidine-based beta-oxoester, which proceeded in very good yield with high level of enantioselectivity (90 %, 95 % ee). The a-allyl moiety was transformed into a 1,4-diketone by Pd-catalyzed Wacker oxidation with molecular oxygen (89 %). This intermediate was cyclized in an intramolecular aldol reaction furnishing the cyclopentenone motif (86 %). Hydrogenation of the C-C double bond gave the cisannulated octahydrocyclopenta[c]pyridine (86 %), which was submitted to Fischer indolization (85 %). Although two regioisomers could be expected, only the angular constitution was observed. Relative and absolute configurations were established by X-ray crystallography of a para-iodo benzamide derivative. The utility of the title compound as scaffold is further highlighted by a number of synthetically useful transformations, for instance formation of carboxamides, sulfonamides, ureas and reductive aminations with aldehydes.

Autocombustion-Promoted Synthesis of Lanthanum Iron Oxide: Application as Heterogeneous Catalyst for Synthesis of Piperidines, Substituted Amines and Light-Assisted Degradations

An autocombustion technique was adopted to synthesize the Perovskite structured Lanthanum iron oxide nanoparticles (LaFeO3, abbreviated as LFO NPs). This technique offered lots of benefits such as short reaction time along with quick heating rate. LFO NPs were fabricated at different calcination temperatures (300-800 degrees C) through the aid of sucrose as chelating agent. The prepared LFO NPs were well characterized by various techniques like X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Vibrating sample magnetometer (VSM), Ultraviolet-Visible spectroscopy (UV-Vis), Brunauer-Emmett-Teller (BET), X-ray Photo-Electron Spectroscopy (XPS) and Transmission electron microscopy (TEM) which affirmed that highly crystalline LFO NPs were obtained at 700 degrees C. Subsequently, the catalytic activity of the LFO NPs was surveyed for three independent approaches: (i) for the synthesis of functionalized piperidines through activation of carbonyl groups in the reacting partners (ii) for the sunlight-assisted mineralization of health hazardous food colorant, Allura Red AC (iii) for the hydrogenation of nitro aromatic compounds (NACs) using NaBH4(sodium borohydride) as source of hydrogen in aqueous medium at room temperature.

A common strategy towards the synthesis of 1,4-dideoxy-1,4-imino-L-xylitol, deacetyl (+)-anisomycin and amino-substituted piperidine iminosugars

A strategy towards the synthesis of three different target molecules, namely 1,4-dideoxy-1,4-imino-L-xylitol, deacetyl (+)-anisomycin and amino-substituted piperidine iminosugars, molecules of potential biological and medicinal significance, is reported from a common amino-vicinal diol intermediate derived from tri-O-benzyl-D-glucal. Construction of the key pyrrolidine ring present in 1,4-dideoxy-1,4-imino-L-xylitol and (+)-anisomycin was a consequence of thermodynamically driven concomitant intramolecular nucleophilic addition reaction of the amino group to the resultant aldehyde obtained by oxidative cleavage of the amino-vicinal diol. Alternatively, double nucleophilic substitution on an amino-diol, after mesylation, with various amines delivered amino-substituted piperidine iminosugars in good yields.
