A Method to Predict Blood-Brain Barrier Permeability of Drug …
Two gold-standard experimental measures of BBB permeability are logBB (the concentration of drug in the brain divided by concentration in the blood) and logPS (permeability surface-area product).
成药性相关小知识(5):血脑屏障通透性 - 知乎 - 知乎专栏
影响中枢药物研发成功的一个主要因素就是血脑屏障(blood-brain barrier, BBB), 几乎阻挡了 100%的大分 子药物及大于 98%的小分子药物[2]。因此, 除了需要 具有较好的活性和代谢性质及较低的毒性等性质 之外, 中枢神经系统药物还需要克服血脑屏障, 在中枢系统达到足够 ...
Molecular determinants of blood–brain barrier permeation - PMC
The blood–brain barrier (BBB) is a microvascular unit which selectively regulates the permeability of drugs to the brain. With the rise in CNS drug targets and diseases, there is a need to be able to accurately predict a priori which compounds in a ...

Log P被用来预测化合物在血脑屏障(BBB)的通透性[8]。 Log P是辛醇和 水相分配 的Log P减去环己烷和水相分配的 Log P。 其差值主要来源于氢键对 Log POW(辛醇/水)和Log PCW(环己烷/水)贡献的差异。
Blood–brain barrier penetration prediction enhanced by …
2022年7月7日 · Blood–brain barrier is a pivotal factor to be considered in the process of central nervous system (CNS) drug development, and it is of great significance to rapidly explore the blood–brain barrier permeability (BBBp) of compounds in silico in early drug discovery process.
Predicting a Drug’s Membrane Permeability: A Computational …
2017年4月28日 · The parameter that determines the lipophilicity of a molecule is LogP (the partition coefficient of the molecule between an aqueous and lipophilic phase, usually water and octanol). LogP is a crucial factor governing passive membrane partitioning; an increase in LogP enhances permeability.

2022年3月26日 · 血脑屏障(brain-blood barrier,BBB)是脑毛细血管阻止某些物质(多半是有害的)进入脑循环,从而保持脑组织内环境基本稳定的一种基本结构。从生物学和功能角度来看,BBB在维持脑内稳态方面起着至关重要的作用,它允许脑组织所需要的营养物质通过,有效阻止一些异物和大 ...
The Relationship Between the Blood-Brain-Barrier and the Central ...
Despite extensive research into the central mechanism of GLP-1RAs and SGLT-2is, the penetration of the blood-brain barrier (BBB) remains controversial. This review discusses the interaction between GLP-1RAs and SGLT-2is and the BBB to …
A prediction model for blood–brain barrier permeation and analysis …
2009年9月1日 · The optimum logP for designing CNS active drug is about 2.9 (Fig. 5). When the logP is lower than 2.9, it has a positive correlation with logBB. It indicates that molecules with higher lipophilic will be partitioned into the lipid bilayer more …
基于机器学习的定量模型 (LogBB_Pred),用于预测 ... - X-MOL
为了推进和提高神经治疗药物发现的成功率,有必要开发一个精确的计算定量模型来确定药物的绝对 logBB 值(大脑中药物浓度与血液中药物浓度的对数比)。 候选药物。 结果在这里,我们开发了一个定量模型 (LogBB_Pred),能够预测查询化合物的 logBB 值。 该模型在独立测试数据集上的 R2 为 0.61,优于其他公开的定量模型。 与仅对化合物是否具有 BBB 渗透性进行分类的可用定性(分类)模型相比,我们的模型与最佳定性模型达到了相同的精度 (0.85),并且远远优于其他 …
