  rdf:value "Drogas diseñadas y sintetizadas, a menudo para uso ilegal en la calle, mediante la modificación de estructuras de fármacos (como las anfetaminas). Revisten especial interés la MPTP (un éster inverso de la meperidina), la MDA (3,4-metilendioxianfetamina) y la MDMA (3,4-metilendioximetanfetamina). Muchas drogas actúan en el sistema aminérgico, las aminas biógenas fisiológicamente activas."@es, "Drugs designed and synthesized, often for illegal street use, by modification of existing drug structures (e.g., amphetamines). Of special interest are MPTP (a reverse ester of meperidine), MDA (3,4-methylenedioxyamphetamine), and MDMA (3,4-methylenedioxymethamphetamine). Many drugs act on the aminergic system, the physiologically active biogenic amines."@en ;
