Dihydrobenzofuran and tetrahydrobenzodifuran functionalities were employed as conformationally restricted bioisosteres of the aromatic methoxy groups in the prototypical hallucinogen, mescaline (1). Thus, 4-(2-aminoethyl)-6,7-dimethoxy-2,3-dihydrobenzofuran hydrochloride (8) and 1-(8-methoxy-2,3,5,6-tetrahydrobenzo[1,2-b:5,4-b']difuran-4-yl)-2- aminoethane hydrochloride (9) were prepared and evaluated
二氢苯并呋喃和四氢苯并呋喃的功能被用作典型致幻剂美斯卡林(1)中构型受限的芳香族甲氧基的生物等排体。因此,4-(2-氨基乙基)-6,7-二甲氧基-2,3-二氢苯并呋喃盐酸盐(8)和1-(8-甲氧基-2,3,5,6-四氢苯并[1,2-b:5制备了(4-b'] difuran-4-yl)-2-氨基乙烷盐酸盐(9),并与1一起评估了在训练中从LSD酒石酸盐中区分出盐水的大鼠的双杠杆药物歧视(DD)范例中的活性。 0.08 mg / kg)。此外,还分别测定了1,8和9取代大鼠皮质匀浆5-HT2A受体中的[3H] ketanserin和取代大鼠海马匀浆5-HT1A受体中的[3H] 8-OH-DPAT的能力。此外,评估了这些化合物与表达克隆的人5-HT2A,5-HT2B和5-HT2C受体的细胞竞争激动剂和拮抗剂的能力。最后,通过测量表达大鼠5-HT2A或5-HT2C受体的NIH 3T3细胞中的磷酸肌
