Abstract
Artificial phosphodiesterases that combine a guanidinium unit with a general base connected by a m-xylylene linker catalyze the transesterification of the RNA model compound 2-hydroxypropyl p-nitrophenyl phosphate (HPNP). The bifunctional catalysts presented in this work show varying extents of cooperation between catalytic units and a rate enhancement of 4 x 10(4) in the most favorable case.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
