In Vitro selectivity of an acyclic cucurbit[n]uril molecular container towards neuromuscular blocking agents relative to commonly used drugs.

ABSTRACT: An acyclic cucurbit[n]uril (CB[n]) based molecular container (2, a.k.a. Calabadion 2) binds to both amino-steroidal and benzylisoquinolinium type neuromuscular blocking agents (NMBAs) in vitro, and reverses the effect of these drugs in vivo displaying faster recovery times than placebo and the γ-cyclodextrin (CD) based and clinically used reversal agent Sugammadex. In this study we have assessed the potential for other drugs commonly used during and after surgery (e.g. antibiotics, antihistamines, and antiarrhythmics) to interfere with the ability of 2 to bind NMBAs rocuronium and cisatracurium in vitro. We measured the binding affinities (Ka, M(-1)) of twenty seven commonly used drugs towards 2 and simulated the equilibrium between 2, NMBA, and drug based on their standard clinical dosage
