Synthesis of a Novel Series of 1,2,3-Triazole-Containing Artemisinin Dimers with Potent Anticancer Activity Involving Huisgen 1,3-Dipolar Cycloaddition Reaction
A “click” ionchannel platform has been established by employing a clickable guanosine azide or alkyne with covalent spacers. The resulting guanosine derivatives modulated the traffic of ions across the phospholipid bilayer, exhibiting a variation in conductance spanning three orders of magnitude (pS to nS).

The targeting of one mRNA in the transcriptome requires small molecules that bind with substantial affinity and specificity. As such, compounds with specificity for individual RNA secondary structural motifs could be useful for targeting RNA. Described herein is the synthesis of a combinatorial library of 105 dimers of deoxystreptamine and the subsequent identification of compounds with specificity for specific RNA hairpin loop sizes, including tetraloops and octaloops. Such compounds will be useful for the perturbation of RNA function in vivo.
