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.

Application of 10310-21-1, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 10310-21-1 is helpful to your research.

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.

The Cl replacement reactions of N/N or N/O spirocyclic monoferrocenylcyclotriphosphazatrienes (1-5) with the piperidine resulted in the geminal- (6-10) and tetra-piperidinophosphazenes with monoferrocenyl pendant arm (11-15). The structures of all the new compounds were determined using spectroscopic techniques. The ultrathin Langmuir-Blodgett (LB) films of two compounds (3 and 12) were prepared. The characterization of the LB films using p-polarized grazing angle (GAIR) and horizontal attenuated total reflectance (HATR) techniques was carried out. The molecular and crystal structure of the compound 6 was examined using X-ray crystallography. In addition, the interactions between six compounds (6, 7, 11, 12, 14 and 15) and pBR322 plasmid DNA were investigated by agarose gel electrophoresis.Graphical AbstractSYNOPSIS The ultrathin Langmuir-Blodgett (LB) films of two of these compounds were prepared.

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.

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.

A Cyclized Polyacrylonitrile Anode for Alkali Metal Ion Batteries

Organic anodes have attracted increasing attention for alkali metal ion batteries. In this work, we discovered that cyclized polyacrylonitrile (cPAN) can serve as an excellent anode for alkali metal ion batteries. Upon activation cycling, as an anode of lithium-ion battery, cPAN exhibits a reversible capacity as high as 1238 mAh g(-1) under a current density of 50 mA g(-1). Based on electrochemical experiments and first-principles calculations, it is demonstrated that the hexagonal carbon ring, piperidine ring, and pyridine nitrogen in ladder cPAN are the main active sites for lithium-ion storage. cPAN displays a unique potential-dependent solid electrolyte interphase formation from 0.1 to 0.01 V vs. Li/Li+. It also displays decent performance as an anode in SIBs and PIBs.
