One-Pot Assembly for Synthesis of 1,4-Dihydropyridine Scaffold and Their Biological Applications

Stable luminescence, size-tunability, and biocompatibility encourage the deployment of Cd-free NPs into diverse biological applications. Here we report one-pot synthesis of blue-emitting and polymerizable silicon quantum dots (Si QDs) from which water-soluble Si QDs embedded polystyrene nanoparticles (SiQD@PS NPs) were prepared using a miniemulsion polymerization approach. The hydrodynamic size of NPs was controlled by KOH to oleic acid molar ratio. Studies on the photoluminescence properties of SiQD@PS NPs in different conditions reveal that they exhibit two-photon luminescence property and high stability against pH and UV exposure. These NPs add new size regime to the Si QDs based luminescent makers for bioimaging and therapy applications.

Abstract Controlling the upconversion luminescence (UCL) intensity ratio, especially pumped at 808 nm, is of fundamental importance in biological applications due to the water molecules exhibiting low absorption at this excitation wavelength. In this work, a series of β-NaYbF4:Er microrods were synthesized by a simple one-pot hydrothermal method and their intense green (545 nm) and red (650 nm) UCL were experimentally investigated based on single particle level under the excitation of 808 nm continuous-wave (CW) laser. Interestingly, the competition between the green and red UCL can be observed in highly Yb3+-doped microcrystals as the excitation intensity gradually increases, which leads to the UCL color changes from green to orange. However, the microcrystals doped with low Yb3+ concentration keep green color which is independent on the excitation power. Further investigations demonstrate that the cross-relaxation (CR) processes between Yb3+ and Er3+ ions result in the UCL competition.

AbstractAmino-functionalized Fe3O4@SiO2 nanoparticles (Fe3O4@SiO2–NH2 NPs) were prepared by treating Fe3O4@SiO2 NPs with (3-aminopropyl)-triethoxysilane. They have been characterized by powder X-ray diffraction, vibrating sample magnetometer, scanning electronic microscopy, energy dispersive X-ray, thermogravimetric analysis and FT-IR spectroscopy. A neat, atom-economical, environmentally benign one-pot multicomponent synthetic route for the synthesis of furo[3,2-c]coumarins in good yields has been devised using the Fe3O4@SiO2–NH2 NPs. The present methodology can be used for the design of libraries and diversity-oriented synthesis, and has potential for biological applications and drug discovery.

Reverse Sequence

We describe the first one-pot orthogonal strategy to prepare well-defined cyclopeptide-based heteroglycoclusters (hGCs) from glycosyl thiols. Both thiol–chloroactetyl coupling (TCC) and thiol–ene coupling (TEC) have been used to decorate cyclopeptides regioselectively with diverse combination of sugars. We demonstrate that the reaction sequence starting with TCC can be performed one-pot whereas the reverse sequence requires a purification step after the TEC reaction. The versatility of this orthogonal strategy has been demonstrated through the synthesis of diverse hGCs displaying alternating binary combinations of α-D-Man or β-D-GlcNAc, thus providing rapid access to attractive heteroglycosylated platforms for diverse biological applications.
