Various located urea and schiff-base bifunctional derivatives: Their gelation and Zn2+ sensing behaviors

Chen, Yu,Lei, Zhimei,Liu, Jie,Sun, He-Lue,Xing, Li-Juan,Yu, Haitao,Zhang, Xin

, (2021)

The efficient combination of various moieties is helpful to develop organic functional molecules. Herein, three of urea and Schiff-base bifunctional derivatives (OG, MG and PG) were prepared from o/m/p-diaminobenzene respectively. Benefitting from the urea and Schiff-base, these derivatives revealed satisfactory gelation capacity. However, the various locations of urea and imine paved them markedly different assembly performances during the gel formation. Additionally, these functional molecules displayed obvious “off-on” fluorescence sensing behaviors towards Zn2+ in solution ascribing to the imine and neighbor phenolic hydroxyl, among which the MG displayed the best Zn2+ selectivity. Crucially, the MG also realized Zn2+ probing at cellular level and its gel gave a visual detection via the gel-sol transition.

Chemoselective modifications for the traceless ligation of thioamide-containing peptides and proteins

Wang, Yanxin J.,Szantai-Kis, D. Miklos,Petersson, E. James

, p. 6262 - 6269 (2016)

Thioamides are single-atom substitutions of canonical amide bonds, and have been proven to be versatile and minimally perturbing probes in protein folding studies. Previously, our group showed that thioamides can be incorporated into proteins by native chemical ligation (NCL) with Cys as a ligation handle. In this study, we report the expansion of this strategy into non-Cys ligation sites, utilizing radical initiated desulfurization to "erase" the side chain thiol after ligation. The reaction exhibited high chemoselectivity against thioamides, which can be further enhanced with thioacetamide as a sacrificial scavenger. As a proof-of-concept example, we demonstrated the incorporation of a thioamide probe into a 56 amino acid protein, the B1 domain of Protein G (GB1). Finally, we showed that the method can be extended to β-thiol amino acid analogs and selenocysteine.

Nitrogen Bridged Diazocines: Photochromes Switching within the Near-Infrared Region with High Quantum Yields in Organic Solvents and in Water

Brahms, Arne,Gescheidt, Georg,Gr?bner, Jens,Herges, Rainer,Lentes, Pascal,R?hricht, Fynn,S?nnichsen, Frank D.,Stadler, Eduard

, (2019)

Diazocines are bridged azobenzenes with superior photophysical properties. In contrast to azobenzenes the Z configuration is thermodynamically stable and the E isomer is metastable. We present a new class of nitrogen bridged diazocines with bathochromically shifted switching wavelengths and remarkably high quantum yields (-NH-CH2- bridged diazocine: φZ→E = 0.57, φE→Z = 0.8). Z to E isomerization is induced by irradiation with blue light, whereas switching back to the Z isomer is accomplished with light in the near-infrared window (up to 740 nm), which is important for medical applications like photopharmacology (deep tissue penetration). Furthermore, substitution at the bridging nitrogen should provide access to widely applicable tricyclic, photoswitchable pharmacophores. The -NAc-CH2- bridged derivative is soluble in water, and all photophysical properties (conversion rates, quantum yields, and thermal half-lives) are largely retained. Hence, this diazocine is an ideal photoswitch for applications in biochemical systems and in photopharmacology.

Rhenium(I) polypyridine diamine complexes as intracellular phosphorogenic sensors: Synthesis, characterization, emissive behavior, biological properties, and nitric oxide sensing

Choi, Alex Wing-Tat,Yim, Vicki Man-Wai,Liu, Hua-Wei,Lo, Kenneth Kam-Wing

, p. 9633 - 9642 (2014)

We report the development of a series of rhenium(I) polypyridine complexes appended with an electron-rich diaminoaromatic moiety as phosphorogenic sensors for nitric oxide (NO). The diamine complexes [Re(N^N)(CO)3(py-DA)] [PF6] (py-DA=3-(N-(2-amino-5-methoxyphenyl)aminomethyl)pyridine; N^N=1,10-phenanthroline (phen) (1a), 3,4,7,8-tetramethyl-1,10-phenanthroline (Me4-phen) (2a), 4,7-diphenyl-1,10-phenanthroline (Ph 2-phen) (3a)) have been synthesized and characterized. In contrast to common rhenium(I) diimines, these diamine complexes were very weakly emissive due to quenching of the triplet metal-to-ligand charge-transfer ( 3MLCT) emission by the diaminoaromatic moiety through photoinduced electron transfer (PET). Upon treatment with NO, the complexes were converted into the triazole derivatives [Re(N^N)(CO)3(py-triazole)][PF 6] (py-triazole=3-((6-methoxybenzotriazol-1-yl)methyl)pyridine; N^N=phen (1b), Me4-phen (2b), Ph2-phen (3b)), resulting in significant emission enhancement (I/I0≈60). The diamine complexes exhibited high reaction selectivity to NO, and their emission intensity was found to be independent on pH. Also, these complexes were effectively internalized by HeLa cells and RAW264.7 macrophages with negligible cytotoxicity. Additionally, the use of complex 3a as an intracellular phosphorogenic sensor for NO has been demonstrated. Emission turned ON for NO: A series of rhenium(I) polypyridine complexes functionalized with an electron-rich diaminoaromatic moiety has been developed as a new class of phosphorogenic sensors for NO. Upon treatment with NO, the weakly emissive complexes were converted into the strongly emissive triazole derivatives, resulting in significant emission enhancement (I/I0≈60; see figure). Experiments showed that the diamine complexes can sense NO that is 1) generated exogenously by NOC-7 in HeLa cells and 2) produced endogenously in RAW264.7 macrophages.
