FRET-based cyanine probes for monitoring ligation reactions and their applications to mechanistic studies and catalyst screening

Herbst,Shabat

, p. 3715 - 3728 (2016)

There is an ever-increasing need to design better methods to selectively connect two molecules under mild aqueous conditions on a small scale. The process of finding such methods significantly relies on the employment of an appropriate assay. We report here a modular FRET-based assay to monitor such reactions and illustrate how the assay is used to monitor two particular reactions: native chemical ligation (NCL) and oxime ligation. For both reactions we show that by employing appropriately designed probes FRET measurements could be used to monitor the reaction's progress. We additionally demonstrate the usefulness of the developed probe system to study the mechanisms of the ligation reactions, for example, in monitoring the formation of a trimeric intermediate in the NCL reaction. Finally, we demonstrate that FRET measurements conducted in our system allow the quantification of the reaction yield and we show the application of our FRET-based assay to catalyst screening for the oxime ligation.

Efficient Pictet–Spengler Bioconjugation with N-Substituted Pyrrolyl Alanine Derivatives

Pomplun, Sebastian,Mohamed, Mohamed Y. H.,Oelschlaegel, Tobias,Wellner, Christian,Bergmann, Frank

Reactivity-dependent PCR: Direct, solution-phase in vitro selection for bond formation

Bio-orthogonal Coupling as a Means of Quantifying the Ligand Density on Hydrophilic Quantum Dots

Zhan, Naiqian,Palui, Goutam,Merkl, Jan-Philip,Mattoussi, Hedi

, p. 3190 - 3201 (2016)

We describe the synthesis of two metal-coordinating ligands that present one or two lipoic acid (LA) anchors, a hydrophilic polyethylene glycol (PEG) segment and a terminal reactive group made of an azide or an aldehyde, two functionalities with great utility in bio-orthogonal coupling techniques. These ligands were introduced onto the QD surfaces using a combination of photochemical ligation and mixed cap exchange strategy, where control over the fraction of azide and aldehyde groups per nanocrystal can be easily achieved: LA-PEG-CHO, LA-PEG-N3, and bis(LA)-PEG-CHO. We then demonstrate the application of two novel bio-orthogonal coupling strategies directly on luminescent quantum dot (QD) surfaces that use click chemistry and hydrazone ligation under catalyst-free conditions. We applied the highly efficient hydrazone ligation to couple 2-hydrozinopyridine (2-HP) to aldehyde-functionalized QDs, which produces a stable hydrazone chromophore with a well-defined optical signature. This unique optical feature has enabled us to extract a measure for the ligand density on the QDs for a few distinct sizes and for different ligand architectures, namely mono-LA-PEG and bis(LA)-PEG. We found that the foot-print-area per ligand was unaffected by the nanocrystal size but strongly depended on the ligand coordination number. Additionally, we showed that when the two bio-orthogonal functionalities (aldehyde and azide) are combined on the same QD platform, the nanocrystal can be specifically reacted with two distinct targets and with great specificity. This design yields QD platforms with distinct chemoselectivities that are greatly promising for use as carriers for in vivo imaging and delivery.

Clicking porphyrins to magnetic nanoparticles for photodynamic therapy

Thandu, Merlyn,Rapozzi, Valentina,Xodo, Luigi,Albericio, Fernando,Comuzzi, Clara,Cavalli, Silvia

, p. 90 - 98 (2014)

A method for the preparation of superparamagnetic iron oxide nanoparticle-porphyrin (SPION-TPP) conjugates through click chemistry, which can be used as novel theranostic nanoagents for photodynamic therapy is developed. The synthesis, characterisation, and evaluation of the photocytotoxicity profiles of the nanoconjugates prepared is reported. Upon light irradiation, SPION-TPP nanoconstructs promote a photodynamic effect in vitro in murine amelanotic melanoma B78-H1 cells, with IC50 values in the region of 800 nm, similarly to unbound TPP, whereas they remain non-cytotoxic in the dark. However, these nanoconstructs show poor cellular uptake, which influences a linear dose-response effect. Therefore, the improvement of delivery to cells has also been studied by conjugating a well-known cell-penetrating peptide (TAT peptide) to the SPION-TPP nanoparticles. The new nanoconstructs show lower IC50 values (in the region of 500 nm) and a clear dose-response effect. Our results suggest that TAT-conjugated SPION-TPP nanoparticles are efficient nanodevices both for tracking drugs by means of magnetic resonance imaging (MRI)-based techniques and for treating cancer cells through photodynamic therapy, thus functioning as promising theranostic nanoagents.

Efficient γ-amino-proline-derived cell penetrating peptide-superparamagnetic iron oxide nanoparticle conjugates via aniline-catalyzed oxime chemistry as bimodal imaging nanoagents

Cavalli, Silvia,Carbajo, Daniel,Acosta, Milena,Lope-Piedrafita,Candiota, Ana Paula,Arus, Carles,Royo, Miriam,Albericio, Fernando

, p. 5322 - 5324 (2012)

Aniline-catalyzed oxime chemistry was employed to conjugate a γ-amino-proline-derived cell penetrating peptide to superparamagnetic iron oxide nanoparticles (SPIONs). Internalization of the novel nanoconjugate into HeLa cells was found to be remarkably higher compared to the analogous TAT-SPION conjugate.

Co-delivery of Doxorubicin and Interferon-γ by Thermosensitive Nanoparticles for Cancer Immunochemotherapy

Yin, Yijia,Hu, Qian,Xu, Chenfeng,Qiao, Qi,Qin, Xianya,Song, Qingle,Peng, Yang,Zhao, Yongdan,Zhang, Zhiping

, p. 4161 - 4172 (2018)

A dual-sensitive nanoparticle delivery system was constructed by incorporating an acid sensitive hydrazone linker into thermosensitive nanoparticles (TSNs) for co-encapsulating doxorubicin (DOX) and interferon γ (IFNγ) and to realize the co-delivery of chemotherapy and immunotherapy agents against melanoma. DOX, a chemotherapeutic drug, was conjugated to TSNs by a pH-sensitive chemical bond, and IFNγ, a potent immune-modulator, was absorbed into TSNs through the thermosensitivity and electrostatics of nanoparticles. Consequently, the dual sensitive drug-loaded TSN delivery systems were successfully built and showed an obvious core-shell structure, good encapsulation efficiency of drugs, sustained and sensitive drug release, prolonged circulation time, as well as excellent synergistic antitumor efficiency against B16F10 tumor bearing mice. Moreover, the combinational antitumor immune responses of hydrazone bearing DOX/IFNγ-TSN (hyd) were strengthened by activating Th1-type CD4+ T cells, cytotoxic T lymphocytes, and natural killer cells, downregulating the expression levels of immunosuppressive cytokines, such as IL10 and TGFβ, and upregulating the secretion of IL2 and TNFα. Taken together, the multifunctional TSNs system provides a promising strategy for multiple drugs co-delivery with distinct properties.

Radical Decarboxylative Carbometalation of Benzoic Acids: A Solution to Aromatic Decarboxylative Fluorination

Xu, Peng,López-Rojas, Priscila,Ritter, Tobias

supporting information, p. 5349 - 5354 (2021/05/05)

Abundant aromatic carboxylic acids exist in great structural diversity from nature and synthesis. To date, the synthetically valuable decarboxylative functionalization of benzoic acids is realized mainly by transition-metal-catalyzed decarboxylative cross couplings. However, the high activation barrier for thermal decarboxylative carbometalation that often requires 140 °C reaction temperature limits both the substrate scope as well as the scope of suitable reactions that can sustain such conditions. Numerous reactions, for example, decarboxylative fluorination that is well developed for aliphatic carboxylic acids, are out of reach for the aromatic counterparts with current reaction chemistry. Here, we report a conceptually different approach through a low-barrier photoinduced ligand to metal charge transfer (LMCT)-enabled radical decarboxylative carbometalation strategy, which generates a putative high-valent arylcopper(III) complex, from which versatile facile reductive eliminations can occur. We demonstrate the suitability of our new approach to address previously unrealized general decarboxylative fluorination of benzoic acids.
