In addition to addiction, the repeated use of (+)-methamphetamine [(+)-METH], (+)-amphetamine [(+)-AMP], or (+/-)-3,4-methylenedioxymethamphetamine ((+/-)-MDMA, commonly called ecstasy) can lead to life-threatening medical problems including cardiovascular injury, severe depression, and psychosis. Currently, there are no specific pharmacotherapies to treat these medical problems. In this study, we report the design and synthesis of two haptens, (S)-(+)-3-(9-carboxynonyloxy)methamphetamine (3a, (+)-METH MO10) and (S)-(+)-3-(5-carboxypentyloxy)methamphetamine (3b, (+)-METH MO6), and their use in generating high affinity (low K-D value) monoclonal antibodies (mAbs) against (+)METH, (+)-AMP, and/or (+)-MDMA. On the basis of results from the determination of mAb K-D values and ligand specificity, the mAbs generated from hapten 3a showed the greatest promise for generating active and passive immunotherapies for treating overdose or addiction from (+)-METH-like stimulants.
