Cancer Targeted Enzymatic Theranostic Prodrug: Precise Diagnosis and Chemotherapy

Shin, Weon Sup,Han, Jiyou,Verwilst, Peter,Kumar, Rajesh,Kim, Jong-Hoon,Kim, Jong Seung

, p. 1419 - 1426 (2016)

The development of targeted and effective theranostic (therapeutic and diagnostic) chemotherapeutic agents is highly desirable for precise diagnosis and treatment of cancer. To realize this goal, we developed a cancer-targeting and enzyme-triggered theranostic prodrug 1, containing 7-ethyl-10-hydroxycamptothecin (SN-38), a well-known anticancer drug, which inhibits topoisomerase I in the cell nucleus; hydroquinone as an enzyme-triggered moiety; and biotin as a cancer targeting unit. Enzyme-triggered theranostic prodrug 1 selectively targets cancer cells and is subsequently activated in the presence of NAD(P)H: quinone oxidoreductase-1 (NQO1), a cytosolic flavoprotein that catalyzes the two-electron reduction of quinone moieties with the concomitant consumption of NADH or NADPH as electron donors. High levels of NQO1 were found in a variety of cancer cell lines compared to healthy cells, and therefore, it is an excellent target for the development of cancer targeted drug delivery systems. Upon preferential cancer cell delivery and uptake, aided by biotin, the enzyme-triggered theranostic prodrug 1 is cleaved by NQO1, with the subsequent release of SN-38, inhibiting topoisomerase I, leading to apoptosis. The drug release and induced apoptosis of cancer cells expressing both biotin receptors and high levels of NQO1 was simultaneously monitored via the innate fluorescence of the released SN-38 by confocal microscopy. In vitro and in vivo studies showed an effective inhibition of cancer growth by the enzyme-triggered theranostic prodrug 1. Thus, this type of enzyme-triggered targeted prodrug therapy is an interesting and promising approach for future cancer treatment.

Hydrophilic 2,9-bis-triazolyl-1,10-phenanthroline ligands enable selective Am(III) separation: A step further towards sustainable nuclear energy

Edwards, Alyn C.,Mocilac, Pavle,Geist, Andreas,Harwood, Laurence M.,Sharrad, Clint A.,Burton, Neil A.,Whitehead, Roger C.,Denecke, Melissa A.

, p. 5001 - 5004 (2017)

The first hydrophilic, 1,10-phenanthroline derived ligands consisting of only C, H, O and N atoms for the selective extraction of Am(iii) from spent nuclear fuel are reported herein. One of these 2,9-bis-triazolyl-1,10-phenanthroline (BTrzPhen) ligands combined with a non-selective extracting agent, was found to exhibit process-suitable selectivity for Am(iii) over Eu(iii) and Cm(iii), providing a clear step forward.

A new signal-on photoelectrochemical biosensor based on a graphene/quantum-dot nanocomposite amplified by the dual-quenched effect of bipyridinium relay and AuNPs

Zhang, Xiaoru,Xu, Yunpeng,Yang, Yanqiang,Jin, Xia,Ye, Sujuan,Zhang, Shusheng,Jiang, Lilin

, p. 16411 - 16418 (2012)

A new photoelectrochemical (PEC) biosensor was developed by using carboxyl-functionalized graphene and CdSe nanoparticles. This sensitive interface was then successfully applied to detection of thrombin based on the dual-quenched effect of PEC nanoparticle, which relied on the electron transfer of a bipyridinium relay and energy transfer of AuNPs. After recognition with an aptamer, the PEC nanoparticle was removed and a signal-on PEC biosensor was obtained. Moreover, the bio-barcode technique used in the preparation of PEC nanoparticle could avoid cross-reaction and enhances the sensitivity. Taking advantages of the various methods mentioned above, the sensitivity could be easily enhanced. In addition, in this work we also investigated graphene that was modified with different functional groups and AuNPs of different particle sizes. Under optimal conditions, a detection limit of 5.9×10-15 M was achieved. With its simplicity, selectivity, and sensitivity, this strategy shows great promise for the fabrication of highly efficient PEC biosensors. PECking order!

Targeted combinational therapy inducing mitochondrial dysfunction

Shin, Weon Sup,Park, Soon Ki,Verwilst, Peter,Koo, Seyoung,Lee, Joung Hae,Chi, Sung-Gil,Kim, Jong Seung

, p. 1281 - 1284 (2017)

We report on a mitochondria-specific combinational theranostic agent, 1. This system contains a chlorambucil prodrug and an aggregation induced emission dye. In addition, compound 1 bears both an intracellular thiol-triggered moiety and a mitochondria targeting unit (triphenylphosphonium). Glutathione (GSH) is the most abundant thiol and its concentrations are significantly higher in a great number of cancer cell lines, compared to normal cells. The GSH-induced prodrug 1 upon activation releases chlorambucil and exhibits mitochondria targeted aggregation induced emission (AIE) fluorescence, resulting in cell apoptosis via the caspase pathway due to mitochondrial dysfunction.

Synthesis of racemic ethanolamine plasmalogen

Pfaendler, Hans Rudolf,Weimar, Volker

, p. 1345 - 1349 (1996)

Racemic C12-ethanolamine plasmalogen 5b was prepared in high yield. The amino group was generated by selective reaction of azide 4b with polymeric triphenylphosphine followed by mild hydrolysis of the intermediate phosphine imine. A novel universal phosphorylation reagent 2-azidoethyl dichlorophosphate (7) was used.

A study of the thermal decomposition of 2-azidoethanol and 2-azidoethyl acetate by ultraviolet photoelectron spectroscopy and matrix isolation infrared spectroscopy

Dyke,Dias,Barros,Hooper,Costa,Beeching,Barros,Cabral,Morris,Cabral,Moutinho,Ogden,Moutinho

, p. 9968 - 9975 (2002)

The thermal decomposition of 2-azidoethanol and 2-azidoethyl acetate were studied by matrix isolation IR spectroscopy and real-time UV photoelectron spectroscopy. The products detected in a flow system at different temperatures (CH2NH, H2CO, N2, CO, and HCN from N3CH2CH2OH and C2H4, CH2NH, HCN, CO2, and N2 from N3CH2COOCH2CH3) allowed mechanisms for decomposition to be proposed. Ab initio calculations were performed for these azides, and application of Koopmans' theorem to the computed orbital energies yielded vertical ionization energies that agreed with experimental values. Two main mechanisms of decomposition of organic azides of the type considered began to emerge. 2-Azidoacetic acid and 2-azidoehtyl acetate decomposed via a concerted process through a cyclic transition state to give the products, while 2-azidoethanol and azidoacetone decomposed via a stepwise mechanism through imine intermediates, which decomposed to give the products via two possible pathways.

Facile formation of hydrogels by using functional precursor polymers and the chemoselective Staudinger coupling

Sallouh, Omar,Weberskirch, Ralf

, p. 189 - 196 (2016)

Hydrogel formation based on chemoselective crosslinking methods has become an important topic in biomedicine. Although the Staudinger ligation has been utilized in protein modification for many years only one example based on polysaccharides has been published to apply this reaction also for hydrogel formation. Therefore, methacrylate monomers with azide Az-MA or triphenylphosphine TPP-MA functional groups were synthesized and used to prepare two water-soluble precursor copolymers P1 (with Az-MA) and P2 (with TPP-MA) by free radical polymerization. The molecular weight and the composition of the copolymers were analyzed by SEC, 1H NMR, FTIR and UV/Vis spectroscopy. Mixing of the water-soluble copolymers P1 and P2 in aqueous media led to the irreversible and easy formation of covalently crosslinked polymers. The kinetics of gelation, swelling and mechanical properties of the hydrogels in aqueous PBS buffer can be tuned by the total polymer concentration and the stoichiometric ratio of the complementary functional groups.

RAFT polymerization of bio-based 1-vinyl-4-dianhydrohexitol-1,2,3-triazole stereoisomers obtained via click chemistry

Beghdadi, Samir,Abdelhedi Miladi, Imen,Ben Romdhane, Hatem,Bernard, Julien,Drockenmuller, Eric

, p. 4138 - 4145 (2012)

Four 1-vinyl-4-dianhydrohexitol-1,2,3-triazole stereoisomers are prepared from isomannide, isoidide, and isosorbide using an alkylation/CuAAC-ligation/ elimination three-step strategy. After characterization of the monomers by NMR, differential scanning calorimetry (DSC), and high-resolution mass spectrometry (HRMS), the corresponding stereocontrolled poly(1-vinyl-4-dianhydrohexitol-1,2, 3-triazole)s are obtained by RAFT polymerization using a xanthate chain transfer agent. A systematic investigation of the structure-properties relationship of both the monomers and polymers highlights the significant impact of the dianhydrohexitols stereochemistry on their physical properties (1H and 13C NMR chemical shifts, physical state, Tg, thermal stability and solubility). A particularly original and unexpected behavior is highlighted since the two different isosorbide-based poly(1-vinyl-4- dianhydrohexitol-1,2,3-triazole) stereoisomers exhibit contrasting solubility in water.
