摘要
一氧化氮,从L-精氨酸合成的一氧化氮合酶,在人体是一个复杂的角色。它几乎有助于每一个生理系统,并已被发现在疾病状态下是保护和有毒的。老年人群面临着越来越多的神经退行性疾病的发病率,在未来一氧化氮在阿尔茨海默氏症和帕金森氏症的病理作用可能是重要的治疗目。一氧化氮的保护作用也是很重要的考虑,通过抑制半胱氨酸天冬氨酸蛋白酶-3、亚硝基化天门冬氨酸、蛋白激酶B和环磷腺苷效应元件结合蛋白转录因子的活化增加。一氧化氮已被证明在长时程增强发挥的一部分作用,揭示了其在突触可塑性的重要性。由于一氧化氮的混合效果,这是一个令人兴奋的和不同的治疗靶点。目前,这些疗法的影响已经在动物研究中探索和发展,但尚未完全实现在人体试验。本文概述了在中枢神经系统中病理学和一氧化氮的保护作用,以及潜在的药物治疗和指示目标。

摘要: Nitric Oxide, synthesized from L-arginine by the nitric oxide synthases, has a complex role within the human body. It contributes to almost every physiological system and has been found to be both protective and toxic in disease states. An aging population faces an increasing incidence of neurodegenerative disease and the pathological action of nitric oxide in Alzheimer’s and Parkinson’s diseases may be important therapeutic targets for the future. Nitric oxide’s protective effects are also important to consider, through inhibition of caspase-3, nitrosylation of NMDA and increased activation of protein kinase B and CREB transcription factor. Nitric oxide has been shown to play a part in long term potentiation, revealing its importance in synaptic plasticity. Due to nitric oxide’s mixed effects it is an exciting and varied therapeutic target. Currently, the impact of these therapies has been explored and developed in animal studies, but is yet to be fully realized in human trials. This paper outlines both the pathological and protective roles of nitric oxide in the central nervous system and the potential pharmacological therapies and targets these indicate.

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
