This library is comprised of more than 350 synthetic cannabinoid standards, including parent compounds and their positional isomers, analogs, and homologs.
The process avoids random conjugation of ADC payload, which would result in multiple positional isomers with potentially different bioactivity, pharmacokinetics, distribution, immunogenicity, safety, and stability profiles.
These parameters allow different atomic distributions to be represented in the linear molecule which result in positional isomers. The potential surfaces, energy and configuration of inclusion complexes, and their dependence on molecular length, composition, and atomic distribution have already been analysed [17-19].
