Modulating Cocaine Vaccine Potency through Hapten Fluorination
摘要:
Cocaine addiction is a long-lasting relapsing illness characterized by cycles of abuse, abstinence, and reinstatement, and antibody-based therapies could be a powerful therapeutic approach. Herein, we explored the possibility of using halogenated cocaine haptens to enhance the immunological properties of anti-cocaine vaccines. Three fluorine-containing cocaine haptens (GNF, GNCF and GN5F) and one chlorine-containing cocaine hapten (GNCl) were designed and synthesized, based upon the chemical scaffold of the only hapten that has reached clinical trials, succinyl norcocaine (SNC). Hapten GNF was found to retain potent cocaine affinity, and also elicit antibodies in a higher concentration than the parent structure SNC. Our data suggests that not only could strategic hapten fluorination be useful for improving upon the current cocaine vaccine undergoing clinical trials, but it may also be a valuable new approach, with application to any of the vaccines being developed for the treatment of drugs of abuse.

(EN) Compounds of the invention are useful for diagnostic imaging of the brain, in particular those regions having dopaminergic neurons. Such imaging is useful for differential diagnosis of Parkinson's disease and for the monitoring of addictive disorders related to abuse of cocaine and treatment thereof.(FR) L'invention concerne des composés servant à l'imagerie diagnostique du cerveau, en particulier des régions ayant des neurones dopaminergiques. Cette imagerie est utile pour un diagnostic différentiel de la maladie de Parkinson et pour la surveillance et le traitement de troubles d'accoutumance dus à la consommation de cocaïne.
