The present disclosure relates to radiolabeled compounds and methods of uses for diagnosis, monitoring, and treatment of various degenerative neurological disorders, neuropsychiatric disorders, brain injuries, vascular diseases, and cancers. Radiolabeled compounds for imaging of microtubules or microtubules and other targets using positron-emission tomography (PET) are specifically disclosed.

Purpose: To study the effects of a regioisomeric change on the biological activities of previously reported water soluble, colchicine site binding, microtubule depolymerizing agents. Methods: Nine pyrrolo[3,2-d]pyrimidines were designed and synthesized. The importance of various substituents was evaluated. Their abilities to cause cellular microtubule depolymerization, inhibit proliferation of MDA-MB-435 tumor cells and inhibit colchicine binding to tubulin were studied. One of the compounds was also evaluated in the National Cancer Institute preclinical 60 cell line panel. Results: Pyrrolo[3,2-d] pyrimidine analogs were more potent than their pyrrolo[2,3-d]pyrimidine regioisomers. We identified compounds with submicromolar potency against cellular proliferation. The structure-activity relationship study gave insight into substituents that were crucial for activity and those that improved activity. The compound tested in the NCI 60 cell line is a 2-digit nanomolar (GI50) inhibitor of 8 tumor cell lines. Conclusion: We have identified substituted pyrrolo[3,2-d]pyrimidines that are water-soluble colchicine site microtubule depolymerizing agents. These compounds serve as leads for further optimization.
