除成瘾外,反复使用(+)-甲基苯丙胺[(+)-冰毒]、(+)苯丙胺[(+)-AMP]或(±)-亚甲基二氧基甲基苯丙胺[(±)-亚甲基二氧基甲基苯丙胺[(±)-MDMA,通常称为摇头丸]可导致危及生命的医疗问题,包括心血管损伤、严重抑郁和精神错乱。目前,还没有特效的药物疗法来治疗这些医学问题。在本研究中,我们报道了两个半抗原--(S)-(+)-3-(9-羧基-壬氧基)甲基苯丙胺[3a,(+)-甲基苯丙胺]和(S)-(+)-3-(5-羧基戊氧基)甲基苯丙胺[3b,(+)-甲基苯丙胺]的设计和合成,并将它们用于制备高亲和力(低Kd值)的抗(+)-甲基苯丙胺、(+)-氨基丙酸甲酯和/或(+)-MDMA单抗。根据mAbKd值和配基特异性的测定结果,半抗原3a产生的mAb在治疗(+)-冰毒类兴奋剂过量或成瘾的主动和被动免疫疗法方面表现出最大的潜力。
In addition to addiction, the repeated use of (+)-methamphetamine [(+)-METH], (+)amphetamine [(+)-AMP], or (±)-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, (+)-METHMO10] and (S)-(+)-3-(5-carboxypentyloxy)methamphetamine [3b, (+)-METH MO6], and their use in generating high affinity (low KD value) monoclonal antibodies (mAbs) against (+)-METH, (+)-AMP, and/or (+)-MDMA. Based on results from the determination of mAb KD 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.
