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.

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.

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.

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.

Moving Synergistically Acting Drug Combinations to the Clinic by Comparing Sequential versus Simultaneous Drug Administrations

Drug combinations acting synergistically to kill cancer cells have become increasingly important in melanoma as an approach to manage the recurrent resistant disease. Protein kinase B (AKT) is a major target in this disease but its inhibitors are not effective clinically, which is a major concern. Targeting AKT in combination with WEE1 (mitotic inhibitor kinase) seems to have potential to make AKT-based therapeutics effective clinically. Since agents targeting AKT and WEE1 have been tested individually in the clinic, the quickest way to move the drug combination to patients would be to combine these agents sequentially, enabling the use of existing phase I clinical trial toxicity data. Therefore, a rapid preclinical approach is needed to evaluate whether simultaneous or sequential drug treatment has maximal therapeutic efficacy, which is based on a mechanistic rationale. To develop this approach, melanoma cell lines were treated with AKT inhibitor AZD5363 [4-amino-N-[(1S)-1-(4-chlorophenyl)-3-hydroxypropyl]-1-(7H-pyrrolo[2,3-d]-pyrimidin-4-yl) piperidine-4-carboxamide] and WEE1 inhibitor AZD1775 [2-allyl-1-(6-(2-hydroxypropan-2-yl) pyridin-2-yl)-6-((4-(4-methylpiperazin-1-yl) phenyl) amino)-1H-pyrazolo[3,4-d] pyrimidin-3(2H)-one] using simultaneous and sequential dosing schedules. Simultaneous treatment synergistically reduced melanoma cell survival and tumor growth. In contrast, sequential treatment was antagonistic and had a minimal tumor inhibitory effect compared with individual agents. Mechanistically, simultaneous targeting of AKT and WEE1 enhanced deregulation of the cell cycle and DNA damage repair pathways by modulating transcription factors p53 and forkhead box M1, which was not observed with sequential treatment. Thus, this study identifies a rapid approach to assess the drug combinations with a mechanistic basis for selection, which suggests that combining AKT and WEE1 inhibitors is needed for maximal efficacy.

Developing a Novel Gold(III) Agent to Treat Glioma Based on the Unique Properties of Apoferritin Nanoparticles: Inducing Lethal Autophagy and Apoptosis

Effective delivery of anticancer agents across the blood-brain barrier (BBB) required innovative strategies to achieve glioma regression. To resolve this problem, we proposed to develop a metal agent that target and treat glioma based on the unique property of apoferritin (AFt) nanoparticles (NPs). Thus, we synthesized a series of Au(III) 3-(4-metyl piperidine)-thiosemicarbazides compounds and analyzed their structure-activity relationships, obtaining a Au agent (C6) with remarkable cytotoxicity in glioma. Moreover, we confirmed that C6 kills glioma cells by inducing lethal autophagy and apoptosis. Importantly, our results revealed that the successfully constructed apoferritin-C6 NPs (AFt-C6 NPs) can effectively cross the BBB, inhibit glioma growth, and selectively accumulate in tumors.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 108-26-9. SDS of cas: 108-26-9.
