- 探讨多德卡格拉-α-D-克西洛 (α12G),一种酸模拟物,作为SR活性调节剂.
- 为了评估α12G在中枢神经系统 (CNS) 疾病的动物模型中的治疗潜力,这种疾病的特征是NMDA功能低下.
主要方法:
- 给C57BL/6J雄性小鼠注射DMM并测量D-氨酸水平.
- 试验室试验以确定α12G对人类SR活性的影响,包括结合亲和性研究.
- 在动物模型中进行行为测试,以评估α12G对过度活跃,脉冲前抑制和记忆的影响.
主要成果:
- 意想不到的是,DMM的使用增加了大脑和血中的D-氨酸水平.
- α12G显著增强了大约八倍的人类SR种族化活动.
- α12G在动物模型中表现出治疗效果,改善过度活跃,脉冲前抑制缺陷和记忆障碍.
结论:
- α12G作为治疗中枢神经系统与NMDA低功能的相关疾病的治疗药物具有前景.
- 该研究确定α12G是SR活动的强有力的增强剂.

02:30Racemic Mixtures and the Resolution of Enantiomers
A racemic mixture, or racemate, is an equimolar mixture of enantiomers of a molecule that can be separated using their unique interaction with chiral molecules or media. Racemic mixtures are denoted by the (±)- prefix. This ‘optical rotation descriptor’ applies to the whole solution of a racemic mixture rather than a specific stereoisomer. Enantiomers typically have the same physical and chemical properties. Hence, they are not easily separable. However, enantiomers can exhibit different...
01:19Allosteric Proteins-ATCase
Binding sites linkages can regulate a protein's function. For example, enzyme activity is often regulated through a feedback mechanism where the end product of the biochemical process serves as an inhibitor.
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis pathway,...
