  丙戊酸类似物的新型酰胺和尿素衍生物的合成及抗痛觉过敏和抗惊厥活性的评价

  摘要：

  丙戊酸（VPA，1）是主要的广谱抗癫痫药和中枢神经系统药物，广泛用于治疗癫痫，双相情感障碍和偏头痛。VPA的临床使用受到两种严重且危及生命的副作用，致畸性和肝毒性的限制。合成了许多VPA类似物及其酰胺，N-甲基酰胺和尿素衍生物，并在神经性疼痛和癫痫的动物模型中进行了评估。其中，两种酰胺和两种尿素衍生物（1）作为抗神经痛药的效价最高，酰胺（19和20）的ED 50值分别为49和51 mg / kg，尿素衍生物的ED 50值为49和74 mg / kg。 （29和33）。19，20，和29是等效于加巴喷丁，用于治疗神经性疼痛的主要药物。这些数据表明上述新型化合物作为用于治疗神经性疼痛的未来药物开发的候选物的巨大潜力。

  钯催化未激活的C（sp 3）–H键的位点选择性氟化

  摘要：

  过渡金属催化的直接C–H键氟化是制备有机氟的有吸引力的合成工具。尽管存在许多直接进行sp 3 C–H官能化的方法，但未活化的sp 3碳的位点选择性氟化仍然是一个挑战。据报道，通过钯催化的双齿配体定向的C–H键官能化过程，可以在未活化的sp 3碳上进行直接，高度位点选择性和非对映选择性的氟化。用这种方法，以乙酸钯为催化剂，Selectfluor为氟源，制备了多种在医学和农业化学中重要的基序的β-氟化氨基酸衍生物和脂族酰胺。

• Redox systems for brain-targeted drug delivery

  Inclusion complexes of hydroxypropyl, hydroxyethyl, glucosyl, maltosyl or maltotriosyl derivatives of β- or γ-cyclodextrin with the reduced, biooxidizable, blood-brain barrier penetrating, lipoidal forms of dihydropyridine = pyridinium salt redox systems for brain-targeted drug delivery provide a means for stabilizing the redox systems, particularly against oxidation. The redox inclusion complexes also provide a means for decreasing initial drug concentrations in the lungs after administration of the systems, leading to decreased toxicity. In selected instances, complexation results in substantially improved water solubility of the redox systems as well.

  Despite the availability of 14 new antiepileptic drugs (AEDs), about 30% of epileptic patients are not seizure-free. Consequently there is substantial need to develop new effective AEDs. A novel class of aromatic amides composed of phenylacetic acid or branched aliphatic carboxylic acids, with five to nine carbons in their carboxylic moiety, and aminobenzenesulfonamide were synthesized and evaluated in the anticonvulsant rat-maximal electroshock (MES) and subcutaneous metrazol seizure (scMet) tests. Fourteen of the synthesized amides had an anticonvulsant ED(50) of <50 mg/kg in the rat-MES test. The amides 2-methyl-N-(4-sulfamoylphenyl)butyramide (10), 2-ethyl-N-(4-sulfamoylphenyl)butyramide (11), and 3,3-dimethyl-N-(4-sulfamoylphenyl)butyramide (15) were the most potent compounds possessing MES-ED(50) values of 7.6, 9.9, and 9.4 mg/kg and remarkable protective index (PI = TD(50)/ ED(50)) values of 65.7, 50.5, and 53.2, respectively. These potent sulfanylamides caused neural tube defects only at doses markedly exceeding their effective dose. The anticonvulsant properties of these compounds make them potential candidates for further development as new, potent, and safe AEDs.

• Potent Anticonvulsant Urea Derivatives of Constitutional Isomers of Valproic Acid
  作者：Jakob Avi Shimshoni、Meir Bialer、Bogdan Wlodarczyk、Richard H. Finnell、Boris Yagen

  Valproic acid (VPA) is a major antiepileptic drug (AED); however, its use is limited by two life-threatening side effects: teratogenicity and hepatotoxicity. Several constitutional isomers of VPA and their amide and urea derivatives were synthesized and evaluated in three different anticonvulsant animal models and a mouse model for AED-induced teratogenicity. The urea derivatives of three VPA constitutional isomers propylisopropylacetylurea, diisopropylacetylurea, and 2-ethyl-3-methyl-pentanoylurea displayed a broad spectrum of anticonvulsant activity in rats with a clear superiority over their corresponding amides and acids. Enanatiomers of propylisopropylacetylurea and propylisopropylacetamide revealed enantioselective anticonvulsant activity, whereas only enantiomers of propylisopropylacetylurea displayed enantioselective teratogenicity. These potent urea derivatives caused neural tube defects, but only at doses markedly exceeding their effective dose, whereas VPA showed no separation between its anticonvulsant activity and teratogenicity. The broad spectrum of anticonvulsant activity of the urea derivatives coupled with their wide safety margin make them potential, candidates to become new, potent AEDs.
