  体内评估选择性碳酸酐酶抑制剂作为潜在的抗惊厥药

  摘要：

  癫痫病是一种常见的神经系统疾病，由抑制性和兴奋性神经传递之间的不平衡引起。众所周知，神经元兴奋性与γ-氨基丁酸（GABA）能量去极化有关。HCO 3 -可以通过膜渗透性碳酸酐酶抑制剂抑制依赖的去极化。我们以前鉴定了一些异喹啉磺酰胺作为人类碳酸酐酶II和VII（hCA II和hCA VII）同工型的有效和选择性抑制剂。鉴于hCA II和hCA VII是参与GABA介导的神经元兴奋的特定同工型，我们假设它们可以代表开发新的抗惊厥药的生物学靶标。因此，对于选定的异喹啉磺酰胺，我们初步测试了它们在DBA / 2小鼠中预防音源性癫痫发作的能力。腹膜内给药后对所有化合物进行评估，其中一些化合物被证明可以保护小鼠免于惊厥。在这一系列化合物中，几种衍生物显示出对目标碳酸酐酶（即hCA II和hCA VII）具有联合体内功效和抑制作用。具体而言，最有趣的分子是1-（4-氨基苯基）-6,7-二甲氧基-3,4-

  Asymmetric transfer hydrogenation (ATH) of imines has been performed with variation in formic acid (F) and triethylamine (T) molar ratios in water. The F/T ratio is shown to affect both the reduction rate and enantioselectivity, with the optimum ratio being 1.1 in the ATH of imines with the Rh-(1S,2S)-TsDPEN catalyst. Use of methanol as a cosolvent enhanced reduction activity. A variety of imine substrates

  亚胺的不对称转移氢化（ATH）随水中甲酸（F）和三乙胺（T）摩尔比的变化而变化。已显示出F / T比影响还原速率和对映选择性，在具有Rh-（1 S，2 S）-TsDPEN催化剂的亚胺的ATH中，最佳比为1.1 。使用甲醇作为助溶剂可增强还原活性。减少了各种亚胺底物，提供了高收率（94–98％）和良好至优异的对映选择性（89–98％）。与普通的共沸FT系统相比，以1.1 / 1 F / T降低速度更快。

  Selective blockade of the orexin-1 receptor (OX1) has been suggested as a potential approach to drug addiction therapy because of its role in modulating the brain's reward system. We have recently reported a series of tetrahydroisoquinoline-based OX1 selective antagonists. Aimed at elucidating structure-activity relationship requirements in other regions of the molecule and further enhancing OX1 potency and selectivity, we have designed and synthesized a series of analogues bearing a variety of substituents at the 1-position of the tetrahydroisoquinoline. The results show that an optimally substituted benzyl group is required for activity at the OX1 receptor. Several compounds with improved potency and/or selectivity have been identified. When combined with structural modifications that were previously found to improve selectivity, we have identified compound 73 (RTIOX-251) with an apparent dissociation constant (K-e) of 16.1 nM at the OX1 receptor and >620-fold selectivity over the OX2 receptor. In vivo, compound 73 was shown to block the development of locomotor sensitization to cocaine in rats.

  Following previous studies we herein report the exploration of the carbonic anhydrase (CA, EC 4.2.1.1) inhibitory effects and enzyme selectivity of a small class of 1-(cyclo)alkylisoquinolines containing a sulfonamide function considered a key feature for inhibiting CA. The results of enzymatic assays against human (h) CA isoforms, hCA I and hCA II (cytosolic, ubiquitous enzymes), hCA IX (transmembrane, tumor-associated), and hCA XIV (transmembrane), suggested that the presence of C-1 small substituents on isoquinoline scaffold controls both inhibitory potency and selectivity. Some derivatives showed potent hCA IX and hCA. XIV inhibitory effects at nanomolar concentrations as well as low affinity for the ubiquitous hCA II. Moreover, we report the X-ray crystal structure of one of these derivatives in complex with dominant human isoform II, thus confirming the sulfonamide zinc interactions. Finally, the results of docking experiments suggested the hypothetic interactions in the catalytic binding site for the most active and selective hCA IX and hCA XIV inhibitor.
