A highly versatile and step-economical route to a new class of guanidinium-rich molecular transporters and evaluation of their ability to complex deliver and launch siRNA are described. for cell penetration and may become tuned for particle size. Relative to the previously reported methyl(trimethylene)carbonate (MTC) scaffold the ether linkage at C2 in the new transporters markedly… Continue reading A highly versatile and step-economical route to a new class of
