“…46−48 Another alluring property of organotin complexes is that they can act as fluorescence bioimaging agents for the localization of specific organelles in live cells by using confocal microscopy. While recently several organotin(IV) complexes have been synthesized with significant luminescent properties for use in organic light-emitting diodes- (OLEDs), 45,49 and biological studies, still it is important to note that bioimaging studies of organotin(IV) complexes are scarcely reported. [37][38][39][40]42,44 Similarly, Schiff bases as fluorescent probes have attracted a great deal of attention as the specific substituents on the ligand moieties change their photophysical properties remarkably.…”

Five fluorescent ONO donor-based organotin(IV) complexes, [Sn IV (L 1−5 )Ph 2 ] (1−5), were synthesized by the onepot reaction method and fully characterized spectroscopically including the single-crystal X-ray diffraction studies of 2−4. Detailed photophysical characterization of all compounds was performed. All the compounds exhibited high luminescent properties with a quantum yield of 17−53%. Additionally, the results of cellular permeability analysis suggest that they are lipophilic and easily absorbed by cells. Confocal microscopy was used to examine the live cell imaging capability of 1−5, and the results show that the compounds are mostly internalized in mitochondria and exhibit negligible cytotoxicity at imaging concentration. Also, 1−5 exhibited high photostability as compared to the commercial dye and can be used in long-term real-time tracking of cell organelles. Also, it is found that the probes (1−5) are highly tolerable during the changes in mitochondrial morphology. Thus, this kind of low-toxic organotin-based fluorescent probe can assist in imaging of mitochondria within living cells and tracking changes in their morphology.

Luminescent Silk Fibroin with Organotin Compounds from Amino Acid Schiff Bases – Microwave‐Assisted Synthesis, Chemo‐Optical Characterization, Cytotoxicity, and Confocal Microscopy

et al. 2017

View full text Add to dashboard Cite

In this work, we report the microwave‐assisted synthesis of six new pentacoordinate and chiral organotin compounds (1–6) derived from amino acid based Schiff bases. The syntheses were achieved through multicomponent reactions (MCRs) of l‐amino acids (tryptophan, tyrosine, and phenylalanine), 2‐hydroxy‐1‐naphthaldehyde, and the corresponding diorganotin oxide (R2SnO, R = nBu or Ph). These compounds were characterized by NMR spectroscopy (1H, 13C, and 119Sn), HRMS, UV/Vis spectroscopy, and fluorescence spectroscopy. All of the compounds in solution exhibited fluorescence with quantum yields (Φ) in the range 0.08 to 0.21. The cytotoxicities of 1–6 at 0.1 µg mL–1 were investigated, and they are practically harmless to melanoma B16F10 cells. The fluorescent staining ability of the organotin compounds toward silk fibroin was investigated by the immersion method and analyzed by confocal microscopy, which showed the efficient and uniform integration of the luminescent compounds. DFT calculations of the interactions of a truncated organotin–fibroin complex are also reported.
