The present invention relates to a class of compounds of formula (I) and (II): wherein R1 is hydrogen; linear or branched C1-C15 alkyl; C1-C15 alkenyl; C3-C6 cycloalkyl; mono, di, tri, tetra, penta substituted aryl or heteroaryl; COOR3; -(CH2)n-aryl; -COO-(CH2)nR3;-(CH2)n-COOR3;-C(O)R3;-C(O)NHR3; or an unsubstituted or substituted oxadiazole; and R2 hydrogen; linear or branched C1-C15 alkyl; C1-C15 alkenyl; C3-C6 cycloalkyl; mono, di, tri, tetra, penta substituted aryl or heteroaryl; unsubstituted or substituted naphthyl; 1, 3-Benzodioxole; fluorine; indole; isoquinoline; quinoline; pyridine; pyrimidine; onnthracene; or-(CH2)n-Ph; wherein the heteroaryl comprises N, O, or S, the mono or multi substituents on the aryl or heteroaryl are independently C1-C5 alkyl, C1-C5 alkenyl, H, F, Cl, Br, I NO2, NHR , or OR, R is C1-C7 alkyl; R3 is C1-C5 alkyl, C1-C5 alkenyl, benzyl, substituted aryl or heteroaryl; and n = 1-7. These compounds are discovered , synthesized and confirmed as potent inhibitors of dopamine (DA), serotonin (5-HT),and norepinephrine inhibitors. These compounds are therefore particularly useful in the treatment conditions or diseases wherein modulation of the monoamine neurotransmitter system involving dopamine (DA), serotonin (5-HT), and norepinephrine plays a role. |
