Abstract [en]

Through the rapid increase in computational power and the development of suitable software, molecular dynamics (MD) has become a promising tool for use in the development of molecularly imprinted polymers (MIPs).1 MD is a computational method based on Newtonian mechanics, which enables the simultaneous simulation of thousands of discrete molecules, and can be used to establish the states of the molecular species present in MIP-prepolymerization mixtures. As detailed understanding of the molecular basis for formation of high affinity MIP sites is still lacking and the physical mechanism underlying specific recognition is still a matter of debate, the use of MD as a tool to investigate MIP-prepolymerization mixtures is highly motivated.1 Recently the first MD simulation of an all-component prepolymerization mixture was presented, which gave a detailed picture of the underlying monomer-template interactions important for the “molecular memory” in MIPs.2

Here, we present results obtained from a series of MD simulations representing all-component MIP/REF prepolymerization mixtures assembled with differences in stoichiometries of functional and crosslinking monomer. In these mixtures, the local anaesthetic drug bupivacaine was used as a template, methacrylic acid as the functional monomer, ethylene dimethacrylate as crosslinking monomer, 2,2’-azobis-(2-methylpropionitrile) as the initiator and toluene as the solvent. Bupivacaine complexation in each system was evaluated with radial distribution functions and hydrogen bond analyses. By correlating the results with the rebinding behaviour of a series of synthesized bupivacaine-MIPs, the relationship between the degree of crosslinking and MIP-performance was highlighted.
