Synthesis of silica-bound amylose by phosphorolytic elongation of immobilised maltoheptaosyl hydrazides
摘要:
Maltoheptaoside-alkoxysilane anchor molecules were synthesised by fusing aliphatic co-Si(OEt3) hydrazide linkers with maltoheptaose. After immobilisation of the primers on porous silica, support-bound amylose was synthesised by phosphorolytic synthesis. The hydrazone linkage as a pre-formed cleavage site allowed removal and Subsequent characterisation of immobilised amylose, which showed a broad molecular weight distribution. Under HPLC conditions, amylose assumed a non-helical conformation, making surface interactions and not complexation the primary separation mechanism. (C) 2002 Elsevier Science Ltd.

Herein we report a detailed description of the structure–activity relationships for a novel series of “C‐linked” 1,2,4‐triazolylazabicyclo[3.1.0]hexanes. These derivatives are endowed with very high in vitro affinity and selectivity for the dopamineD3receptor. An optimization with respect to undesired affinity toward the hERG potassium channel is also reported. Members of this compound series also
