The present invention relates to heterocyclic compounds for use in the treatment of diseases. In particular, the invention relates to heterocyclic compounds for use in the treatment of neurodegenerative diseases, such as Parkinson's or Alzheimer's disease, and methods of making and using the same. The heterocycle compounds contain at least one electronegative atom and comprise a hydroxyl group or substituted hydroxyl group at the 1-position and the carbon at the 2-position being a carbonyl group.
Quantum chemistry-based interpretations on the lowest triplet state of luminescent lanthanides complexes. Part 1. Relation between the triplet state energy of hydroxamate complexes and their luminescence properties
upon experimental and theoretical investigations of the excited state properties of a series of four simple aromatic hydroxamate ligands coordinated to TbIII and GdIII ions. By using previously reported crystallographic data, the structural and energies properties of these systems were investigated in the ground and first excited triplet states at the density functional theory (DFT) level of calculations
Several kinds of cyclic hydroxamic acids were synthesized. They exhibited metal chelating abilities and analgesic activities, as expected. Besides these activities, some of these compounds inhibited the growth of microorganisms.

Iron dysregulation, dopamine depletion, cellular oxidative stress and α-synuclein protein mis-folding are key neuronal pathological features seen in the progression of Parkinson's disease. Ironchelators endowed with one or more therapeutic modes of action have long been suggested as disease modifying therapies for its treatment. In this study, novel 1-hydroxypyrazin-2(1H)-one ironchelators were synthesized
铁失调、多巴胺耗竭、细胞氧化应激和 α-突触核蛋白错误折叠是帕金森病进展中的关键神经元病理特征。具有一种或多种治疗作用模式的铁螯合剂长期以来一直被建议作为其治疗的疾病修饰疗法。本研究合成了新型1-羟基吡嗪-2( 1H )-酮铁螯合剂,并评估了其理化性质、铁螯合能力、抗氧化能力以及在帕金森病细胞培养模型中的神经保护作用。物理化学性质(log β 、log D 7.4 、pL 0.5 )表明这些配体穿透细胞膜并形成较弱铁络合物的能力比密切相关的 1-羟基吡啶-2(1 H )-one 更差。尽管如此,我们表明这些配体在体外针对儿茶酚胺能神经毒素 6-羟基多巴胺提供的神经保护水平与之前使用 1-羟基吡啶-2(1 H )-one 和临床使用的铁螯合剂去铁酮所观察到的神经保护水平相当。与对照相比,其中两种配体将细胞活力恢复至 ≥89%。其中两个配体被赋予了额外的酚部分,试图衍生出具有双重铁螯合/抗氧化活性的多功能螯合剂。
