产品概览 | Product Overview
左旋多巴 (Levodopa, L-DOPA, (-)-DOPA) 是一种非蛋白质芳香族氨基酸,化学名为(S)-2-氨基-3-(3,4-二羟基苯基)丙酸。它是多巴胺 的直接前体,能够穿过血脑屏障进入中枢神经系统,在脑内脱羧转化为多巴胺,从而有效补充帕金森病 患者脑中缺失的多巴胺,是目前治疗帕金森病的“金标准”药物。与人工合成的多巴胺 不同,天然来源的左旋多巴是左旋 手性构型,具有生物活性。
Levodopa, a non-proteinogenic aromatic amino acid, is the direct precursor to dopamine. Unlike dopamine itself, it can cross the blood-brain barrier. In the brain, it is decarboxylated to dopamine, effectively replenishing the dopamine deficiency in Parkinson's disease patients, making it the "gold standard" therapy. Naturally sourced L-DOPA is the active levorotatory enantiomer.
核心药理与功效 | Core Pharmacology & Efficacy
治疗帕金森病的基石 | Cornerstone of Parkinson's Disease Therapy: 作为多巴胺前体,能显著改善帕金森病的主要症状,如静止性震颤、肌肉僵直、运动迟缓、姿势平衡障碍,提高患者生活质量。
As a dopamine precursor, it significantly alleviates core Parkinson's symptoms (resting tremor, rigidity, bradykinesia, postural instability) and improves patients' quality of life.
抗肝昏迷辅助治疗 | Adjuvant for Hepatic Coma: 在肝脏,左旋多巴可转化为去甲肾上腺素和多巴胺,竞争性地拮抗苯乙醇胺和羟苯乙醇胺 等假性神经递质,帮助恢复神经功能,促进苏醒。
In the liver, it is converted to norepinephrine and dopamine, competitively antagonizing false neurotransmitters like phenylethanolamine and octopamine, aiding in neurological recovery and consciousness restoration.
其他潜在研究应用 | Other Potential Research Applications:
影响垂体激素分泌(如生长激素、催乳素)。
Influencing pituitary hormone secretion (e.g., growth hormone, prolactin).
作为神经内分泌研究 和精神药理学研究 的重要工具。
Serving as a crucial tool in neuroendocrine and psychopharmacological research.
在运动科学、情绪与认知功能调节等领域有研究价值。
Holds research value in sports science, mood and cognitive function modulation.
