Probes for narcotic receptor mediated phenomena. 13. Potential irreversible narcotic antagonist-based ligands derived from 6,14-endo-ethenotetrahydrooripavine with 7-(methoxyfumaroyl)amino, (bromoacetyl)amino, or isothiocyanate electrophiles: chemistry, biochemistry, and pharmacology

(methoxyfumaroyl)amino) and examined in vivo for their narcotic agonist and antagonist activities and for their ability to interact with opioid receptors in vitro. The N-(cyclopropylmethyl)-substituted compounds were found to have the highest affinity for opioid receptors among these N-substituted compounds, although all of them were found to be reasonably potent narcotic antagonists in the mouse tail flick vs. morphine
合成了N-烯丙基-,N-(环丙基甲基)-和N-丙基-内酯-乙炔四氢去甲肾上腺素(N-取代的6,14-内酯-乙炔-4,5-环氧-3-羟基-6-甲氧基吗啡喃)将C-7位上的部分酰化或烷基化(异硫氰酸根,(溴乙酰基)氨基和(甲氧基富马酰基)氨基),并在体内检查其麻醉激动剂和拮抗剂活性,以及它们与阿片受体在体外相互作用的能力。在这些N-取代的化合物中,发现N-(环丙基甲基)-取代的化合物对阿片受体具有最高的亲和力,尽管在小鼠甩尾vs吗啡试验中发现它们都是相当有效的麻醉剂。在小鼠静脉内注射时,它们的体内效力是纳洛啡的1/8至4倍。大鼠脑膜结合研究表明,该化合物与阿片受体相互作用的效力范围为吗啡(8c,9c和10c)的0.5倍至吗啡(8b)的0.017。在使用NG108-15神经母细胞瘤-神经胶质瘤杂交细胞和/或使用NG108-15神经母细胞瘤和//或在大鼠脑膜制剂中。发现8c和10c在一定程度上
