Synthesis and β-Adrenergic Properties of (Z)-N-[3-(Alkylamino)-2-hydroxypropylidene](aryl-methyloxy)amines: Effects of the Configuration Around the Methyloxyiminomethyl (MOIM) Double Bond on the Biopharmacological Properties of MOIM-type β-Blocking Agents
摘要:
The N-isopropyl- (3a-g) and N-tert-butyl-substituted (4a-g) (Z)-N-(3-(amino)-2-hydroxypropylidene)(arylmethyloxy)amines were synthesized in order to compare their beta(1)- and beta(2)-adrenergic properties with those of their previously studied corresponding analogues with the E configuration (la-g and 2a-g). Compounds 3 and 4 were tested for their affinity for beta(1)- and beta(2)-adrenoceptors by radioligand binding experiments, and the compounds with the highest affinity were also assayed for their activity towards the same types of beta-adrenoceptors by functional tests on isolated preparations. The Z-methyloxyiminomethyl (Z-MOIM) compounds 3 and 4 proved to possess, on the whole, affinity (K-i) and activity (pIC(50)) indices similar to those of the E isomers 1 and 2, thus indicating that for the MOIM-type beta-adrenergic antagonists 1-4, the type of configuration around the MOIM double bond does not have any appreciable effect either on the affinity or on the activity towards beta-adrenoceptors. These results are rationalized on the basis of the steric and electronic analogies existing between the MOIM groups of 1-4 in the two types of configurations (E and Z). (C) 1998 Elsevier Science Ltd.

阿尔茨海默病(AD)是一种严重的多因素神经退行性疾病,其特征是大脑中神经元的进行性丧失。尽管进行了很多研究,但 AD 进展的发病机制和机制尚未完全清楚。只有少数药物被批准用于治疗 AD。 AD 的多因素特征表明,开发能够针对与该疾病相关的多种病理机制的分子非常重要。因此,在全球公认的多功能配体治疗兴趣的背景下,我们在此报告了一组五种( 1a - e )新型阿魏酸杂化化合物(即阿魏酰基-苄氧基酰胺衍生物)的合成、表征、理化和生物学评估包含不同的取代基,作为潜在的抗阿尔茨海默氏病药物。这些杂化物可以保留天然阿魏酸支架的自由基清除活性和金属螯合能力,还表现出良好/温和的抑制自身Aβ聚集的能力以及相当好的抑制Cu诱导的Aβ聚集的能力。与已知的口服药物相比,预测的药代动力学特性表明吸收良好。

the progression of diabeticcomplications. Herein we describe a novel series of (E)-benzaldehyde O-benzyl oximes 6a–e, 7a–e, 8a–e, and 9–11 as ALR2 inhibitors endowed with anti-oxidant properties. Inspired by the natural products, the synthesized derivatives are characterized by a different polyhydroxy substitution pattern on their benzaldehyde fragment, which proved crucial for both the enzyme inhibitory
醛糖还原酶 (ALR2) 是一种负责产生由糖尿病高血糖引起的细胞毒性的酶,这反过来又导致活性氧的产生,从而引发氧化应激。因此,抑制 ALR2 同时通过双重作用药物追求伴随的抗氧化活性现在被认为是预防或至少延缓糖尿病并发症进展的黄金标准治疗方法。在此,我们描述了一系列新型 ( E )-苯甲醛O-苄基肟6a–e 、 7a–e 、 8a–e和9–11作为具有抗氧化特性的 ALR2 抑制剂。受天然产物的启发,合成的衍生物的特点是苯甲醛片段上具有不同的多羟基取代模式,这对酶抑制活性和抗氧化能力至关重要。衍生物( E )-2,3,4-三羟基苯甲醛O- (3-甲氧基苯甲基)肟( 7b )和( E )-2,3,4-三羟基苯甲醛O- (4-甲氧基苯甲基)肟( 8b )结果为最有效的双效产品,证明将最佳的 ALR2 抑制特性与显着的抗氧化功效结合在一起。

A series of O-benzyl-N-(9-acridinyl)hydroxylamines was prepared, isolated, and evaluated for biological activity using both thermal denaturation and MTT assays. Changes in the thermal denaturation temperature of genomic calf-thymus DNA ranged from +6.6 °C to +20.2 °C. MTT assays on SNB-19 glioblastoma cells provided biological activity that ranged from 17.4 μM to 33.2 μM. Both evaluation methods of
