Drug Mimetic Organogelators for the Control of Concomitant Crystallization of Barbital and Thalidomide

Saikia, Basanta and Mulvee, Matthew T. and Torres-Moya, Ivan and Sarma, Bipul and Steed, Jonathan W. (2020) 'Drug Mimetic Organogelators for the Control of Concomitant Crystallization of Barbital and Thalidomide.', Crystal growth & design., 20 (12). pp. 7989-7996.


A strategic approach to control the polymorphism of two related drugs by introducing a drug-mimetic imide functional group into the molecular weight organogelator structure is presented. This was achieved with novel aminoglutethimide-derived bis(urea) organogelators designed to form gels that act as targeted crystallization media for (±)-thalidomide and barbital. The organogelators prevent concomitant crystallization, a serious issue for drug formulation and development. This work demonstrates the potential to control concomitant crystallization with rationally designed supramolecular gelators.
