Syntheses of biomimetic low-molecular weight poly-(R)-3-hydroxybutanoate me
diated by three types of supramolecular catalysts are presented. The utilit
y of these synthetic polyesters for preparation of artificial channels in p
hospholipid bilayers capable of sodium and calcium ion transport across cel
l membranes, is discussed. Further studies on possible applications of thes
e bio-polymers for manufacturing drugs of prolonged activity are under way.
