reported on hydroxy substituted 2-benzylidene-1-indanone derivatives as A1 and/or A2A antagonists for the potential treatment of neurological conditions. A lead compound (1a) was identified with both A1 and A2A affinity in the micromolar range. The current study explored the structurally related methoxy substituted 2-benzylidene-1-indanone derivatives with various substitutions on ring A and B of the benzylidene
先前的研究报道了羟基取代的2-亚苄基-1-茚满酮衍生物作为A1和/或A2A拮抗剂可潜在治疗神经系统疾病。鉴定出在微摩尔范围内具有A1和A2A亲和力的前导化合物(1a)。当前的研究探索了与结构相关的甲氧基取代的2-亚苄基-1-茚满酮衍生物,在亚苄基茚满酮骨架的环A和B上具有各种取代基,以增强A1和A2A的亲和力。这导致在纳摩尔量范围内具有A1和A2A亲和力的化合物,即2c(A1 K i(大鼠)= 41 nM; A2A Ki(大鼠)= 97 nM)在环A上被C4-OCH3取代以及间位( 3')在环B和2e上进行羟基取代(A1 K i(大鼠)= 42 nM;在A2A Ki(大鼠)= 78 nM)在环A上进行C4-OCH3取代以及间位(3')和对位(4 ' )在环B上被二羟基取代。此外,2c是A1拮抗剂。因此,甲氧基取代的2-亚苄基-1-茚满酮支架对于新型A1和A2A拮抗剂的设计是非常有前途的。
