Metabolism of macrocyclic drugs

Metabolite Tales Blog

Not only this, the reduction in rotatable bonds and consequent reduction in susceptibility to metabolism is an additional benefit [4]. The resulting macrocyclic structure was found to be associated with improved metabolic stability and low propensity for P-gp efflux compared to the acyclic analog [13]. Balazs et al.,
