A series of apomorphine ((-)-1, APO)-derived analogues ((+/-)-3, (-)-4-(-)-6) were designed and synthesized by hybridizing APO with a privileged 2-aminothiazole functionality which was lent from the orally available anti-parkinsonian drug, pramipexole (2). Among these hybridized compounds, catecholic aporphine (-)-6 shows good affinity at the D(2) receptor with K(i) of 328nM, slightly less potent (3-fold)
通过将APO与特有的2-氨基噻唑杂交,设计并合成了一系列阿朴吗啡((-)-1,APO)衍生的类似物((+/-)-3,(-)-4-(-)-6)口服抗帕金森病药物普拉克索(2)提供的功能性。在这些杂交的化合物中,儿茶酚卟啉(-)-6在D(2)受体上具有328nM的K(i)的良好亲和力,效力稍弱(3倍),但对D(1)受体的选择性比母体化合物,APO。尽管在D(2)受体上具有降低的亲和力,但紫粉15和18在D(1)和5-HT(1A)受体上均显示出显着的效力。前一种化合物在两个受体上均等价(分别为K(i):116和151nM),而后者在D(1)上的效价(K(i):78nM)是5-HT的8倍。 (1A)受体(K(i):640nM)。
