  Preliminary Pharmacological Evaluation of Enantiomeric Morphinans

  摘要：

  A series of levo- and dextromorphinan pairs have been synthesized and evaluated for their affinities to the mu, kappa, and delta opioid receptors, the N-methyl-D-aspartate (NMDA) channel, and sigma 1 and 2 receptors. It was found that levo isomers tended to have higher affinities at the opioid receptors and moderate to high affinities to the NMDA and sigma receptors, while dextro isomers tended to have lower affinities to the opioid receptors but comparatively higher affinities to the NMDA and sigma receptors. This series of compounds have interesting and complex pharmacological profiles, and merit further investigation as potential therapies for drug abuse treatment.

  来自马肝的新型细胞色素P450 CYP2D50的互补DNA克隆，功能表达和表征

  摘要：

  CYP2D家族的成员仅占总肝CYP450的2-4％，但是，它们负责代谢20-25％的通常处方的治疗化合物。CYP2D酶已在许多不同物种中得到鉴定。然而，这些酶的代谢活性的巨大差异已被充分证明。在马匹中，马肝脏微粒体的研究提示存在CYP2D家族成员，但尚未明确证明其存在。在这项研究中，从马肝中克隆了一种编码新型CYP2D酶（CYP2D50）的cDNA，并在杆状病毒表达系统中表达。CYP2D50的核苷酸序列与人CYP2D6的核苷酸序列高度同源，因此使用右美沙芬和去甲异喹对酶的活性进行了表征，人类直系同源物的两种同工型选择性底物。当CYP2D50与NADPH CYP450还原酶的摩尔比为1:15时，CYP2D50对右美沙芬具有最佳的催化活性。尽管CYP2D50和CYP2D6具有显着的序列同源性，但两种酶之间的催化活性却存在显着差异。CYP2D50右美沙芬-O-脱甲基酶活性比人类CYP2D6慢近1

  The invention provides inhibitors of a sterol C14-demethylase, a new series of 4- aminopyridyl-based lead inhibitors targeting Trypanosoma cruzi CYP51 (TcCYP51) developed using structure-based drug design as well as structure -property relationship (SPR) analyses. The screening hit starting point, LP 10 (KD < 42 nM; EC50 of 0.65 μΜ), has been optimized to give the potential leads that have low nanomolar binding affinity to TcCYP51 and significant activity against T. cruzi amastigotes cultured in human myoblasts. Many of the optimized compounds have improved microsome stability, and most are selective against the T. cruzi CYP51 relative to human CYPs 1A2, 2D6 and 3A4 (<50% inhibition at 1 μΜ). A rationale for the improvement of microsome stability and selectivity of inhibitors against human metabolic CYP enzymes is presented. In addition, the binding mode of several compounds of the invention with the T. brucei CYP51 (TbCYP51) ortholog has been characterized by x-ray structure analysis. Orally active compounds and their cyclodextrin complexes have been shown to be effective against Chagas-infected mice.

  该发明提供了一种甾醇C14-去甲基酶的抑制剂，这是一种新系列基于4-氨基吡啶的首选抑制剂，通过基于结构的药物设计以及结构-性质关系（SPR）分析来瞄准Trypanosoma cruzi CYP51（TcCYP51）而开发的。筛选起始点LP 10（KD < 42 nM；EC50为0.65 μΜ）已经经过优化，产生了具有低纳摩尔级别结合亲和力和对在人类肌细胞培养的T. cruzi游离体的显著活性的潜在首选抑制剂。许多经过优化的化合物具有改善的微粒体稳定性，大多数相对于人类CYPs 1A2、2D6和3A4对T. cruzi CYP51具有选择性（在1 μΜ下<50%的抑制）。提出了改善微粒体稳定性和抑制剂对人类代谢CYP酶的选择性的理由。此外，通过X射线结构分析表征了该发明的几种化合物与T. brucei CYP51（TbCYP51）同源物的结合方式。口服活性化合物及其环糊精复合物已被证明对克氏病感染的小鼠有效。

  Controlled-release dosage forms containing an opioid agonist; an opioid antagonist; and a controlled release material release during a dosing interval an analgesic or sub-analgesic amount of the opioid agonist along with an amount of said opioid antagonist effective to attenuate a side effect of said opioid agonist. The dosage form provides analgesia for at least about 8 hours when administered to human patients. In other embodiments, the dose of antagonist released during the dosing interval enhances the analgesic potency of the opioid agonist.

  含有阿片激动剂、阿片拮抗剂和受控释放材料的控释剂型，其在给药间隔期间释放阿片激动剂的镇痛或亚镇痛量以及足以减轻所述阿片激动剂的副作用的阿片拮抗剂的量。当给予人类患者时，该剂型提供至少约8小时的镇痛作用。在其他实施例中，给药间隔期释放的拮抗剂剂量增强了阿片激动剂的镇痛效力。
