  Deoxymorphines: role of the phenolic hydroxyl in antinociception and opiate receptor interactions

  摘要：

  Several 3-deoxy opioids and 3,6-dideoxydihydromorphine was synthesized to ascertain the effect of the phenolic hydroxyl group on antinociceptive potency and receptor binding affinity. Catalytic reduction of the 3-tetrazolyl ether derivatives of dihydromorphine provided the entry into the 3-deoxydihydro series. The prototype, 3-deoxymorphine, was prepared by lithium aluminum hydride reduction of 3-deoxy-N-carbethoxymorphinone, obtained via its 7-(phenylseleno) derivative. 3-Deoxydihydromorphinone and 3,6-dideoxydihydromorphine were found to be about as potent as, or more potent than, morphine in standard antiociceptive assays. Each of them, however, was less potent than the comparable 3-hydroxy analogue, and their binding affinity to the opiate receptor was substantially decreased. The epoxy ring in 3.6-dideoxydihydromorphine was found to increase the antinociceptive potency of the compound.

  口服活性阿扑吗啡候选药物的早期工艺开发和放大

  摘要：

  新型阿扑吗啡帕金森氏症候选药物 (MCL-509) 的制造路线已从 mg 实验室规模发展到适用于 20-50 L 规模的规模。虽然无法改进合成顺序，但所有六个反应步骤都需要显着改进才能扩大规模。去除了有害和有毒的试剂以及有害的步骤；去除所有浓缩至干燥和层析纯化；隔离在操作上得到简化，工厂周期时间缩短。两对步骤（1 和 2；5 和 6）被成功地压缩，并且重新设想了步骤 3、4 和 5，以便所有三个步骤都用替代试剂进行了实质性的重新开发。现在完全依靠结晶分离，每个中间体的产率、纯度和颜色都有了很大的提高。所有六个工艺步骤都可以很容易地转移到中试工厂，在以每批次 20-50 L 的规模进行生产之前，只需要进行最少的调整工作。因此，制造活动基本上按预期进行，没有出现问题，同时材料产量增加了大约 10 倍，同时还实现了必要的质量改进。

• An investigation of the N-demethylation of 3-deoxymorphine and the affinity of the alkylation products to μ, δ, and κ receptors

  The N-demethylation of 3-deoxymorphine (1) was investigated using methyl chloroformate and hydrazine. 3-Deoxynormorphine (2) was obtained in 70% yield, and 3-deoxydihydronormorphine (3) was also obtained as a side product. The mu, delta, and kappa receptor binding affinity of a series of N-substituted 3-deoxynormorphines 6 and 7 and N-substituted 3-deoxydihydronormorphines 8-11 was also determined.
