also resulted in analogues that were partially effective in blocking delta 9-THC antinociceptive activity. This blockade was observed particularly in compound 10, which also showed unusually toxic properties. Incorporation of a seven-membered oxepin in the delta 9-THC structure eliminated cannabinoid activity although substitution of the pentyl side chain with a 1,2-dimethylheptyl in the oxepin 14b resulted
合成了几种C-10取代的大麻二酚(CBD)衍生物和新型的δ9-四氢大麻酚(δ9-THC)oxepin衍生物,并评估了其在小鼠和狗中的生物学活性。在Me2SO中用各种胺处理10-溴大麻二酚二乙酸酯(3),得到相应的10-氨基大麻二酚衍生物4-6。类似地,用NaN 3处理3得到叠氮基化合物7,用LiA1H4处理得到叠氮基化合物10-氨基大麻二酚9。但是,用CrCl2还原7形成酰胺8,然后再用LiA1H4还原得到N-乙基类似物10。在存在二环己基碳二亚胺的情况下,由9与11形成11,然后将其用HCl脱保护以得到类似物13。通过在室温下在CH 3 OH / H 2 O中用Na 2 CO 3处理,由3合成氧杂环丁酸酯类似物14a。类似地制备二甲基庚基类似物14b。N-乙基(10),N-甲基-N-炔丙基(6)和吗啉代(4)基团在位置10的CBD中的结合产生了比CBD更有效的类似物,可在小鼠中产生低活性
