Synthesis of 1,4-Disubstituted Mono and Bis-triazolocarbo-acyclonucleoside Analogues of 9-(4-Hydroxybutyl)guanine by Cu(I)-Catalyzed Click Azide-Alkyne Cycloaddition [PDF]
A series of novel mono-1,2,3-triazole and bis-1,2,3-triazole acyclonucleoside analogues of 9-(4-hydroxybutyl)guanine was prepared via copper(I)-catalyzed 1,3-dipolar cycloaddition of N-9 propargylpurine, N-1-propargylpyrimidines/as-triazine with the ...

Simultaneous utilization of calix[4]pyrrole‐ and crown ether‐based molecular recognition allows the construction of a high molecular weight alternating supramolecular polymer. This heat processible polymer can be used as a durable and reusable adhesive on glass and steel with temperature‐enhanced adhesion strength without the need for a solvent ...

Synthesis of a Versatile Building Block for the Preparation of 6-N-Derivatized α-Galactosyl Ceramides: Rapid Access to Biologically Active Glycolipids [PDF]
A concise route to the 6-azido-6-deoxy-α-galactosyl-phytosphingosine derivative 9 is reported. Orthogonal protection of the two amino groups allows elaboration of 9 into a range of 6-N-derivatized α-galactosyl ceramides by late-stage introduction of the ...

High‐Throughput Microfluidic‐Mediated Assembly of Layer‐By‐Layer Nanoparticles
The layer‐by‐layer (LbL) assembly of polymer films on nanoparticle (NP) surfaces is a promising technique for targeted drug delivery. Despite its success in preclinical mouse models, a current good manufacturing practices (cGMP) compliant, clinical‐scale production method has been lacking.
