The aim of the present study was to develop a blood-brain barrier (BBB) permeability model that is applicable in the drug discovery phase. The BBB ensures proper neural function, but it restricts many drugs from entering the brain, and this complicates the development of new drugs against central nervous system diseases. Many in vitro models have been developed to predict BBB permeability, but the permeability characteristics of the human BBB are notoriously complex and hard to predict…

An Insect-Based Ex Vivo Blood Brain Barrier Efflux Assay

The locust ex-vivo BBB model holds promise as a cheap model with a high-throughput screening potential in the early discovery phase of CNS drugs, which indicates a conserved mechanism of brain efflux activity between insects and vertebrates.

Characterization of a novel brain barrier ex vivo insect-based P-glycoprotein screening model

It is shown that the locust model has the potential to act as a robust and convenient model for assessing BBB permeability in early drug discovery and to retain the major cues that maintain and modulate the physiological function of the brain barrier.

Development of an a priori computational approach for brain uptake of compounds in an insect model system.

Barrier mechanisms in the Drosophila blood-brain barrier

Findings strengthen the notion that many BBB mechanisms are conserved between vertebrates and invertebrates, and suggest that novel findings in invertebrate model organisms will have a significant impact on the understanding of vertebrate BBB functions.

Molecular determinants of blood-brain barrier permeation.

The different computational tools available today, as well as the experimental methods used to determine BBB permeability, are explored, which include in vitro models and the in vivo models that yield the dataset the authors use to generate predictive models.

Identification of a Functional Homolog of the Mammalian CYP3A4 in Locusts

Not only may locusts be a model useful for determining BBB permeation, but possibly insects could be used in metabolism investigation, however, extensive characterization of the insect model is necessary to determine its applicability.

Identification of a Functional Homolog of the Mammalian CYP 3 A 4 in Locusts Line

Not only may locusts be a model useful for determining BBB permeation, but possibly insects could be used in metabolism investigation, however, extensive characterization of the insect model is necessary to determine its importance.

An ex Vivo Model for Evaluating Blood-Brain Barrier Permeability, Efflux, and Drug Metabolism.

Overall, the experiments indicated that invertebrates might be useful for screening of blood-brain barrier permeation, efflux, metabolism, and analysis of the unbound fraction of drugs in the brain in early drug discovery.

Development of a sensitive and quantitative capillary LC-UV method to study the uptake of pharmaceuticals in zebrafish brain

Quantitative experiments carried out on pooled samples of six zebrafish demonstrated the selective semipermeable nature of the blood-brain barrier after incubating the zebra fish at the maximum tolerated concentration for the investigated pharmaceuticals.

Novel models for assessing blood–brain barrier drug permeation

This focused review covers novel models which have been developed or are in the process of being developed which can be used in modeling BBB and the main model organisms covered here are the grasshopper, fruit fly and zebrafish.

Assays to predict drug permeation across the blood-brain barrier, and distribution to brain.

In combination with in silico and in vivo models, the portfolio of methods establishing and predicting CNS drug PK is now very powerful, allowing much more accurate iterative feedback to chemists to optimise compound profiles through the drug discovery and development programme.

Evolutionary Conservation of Vertebrate Blood–Brain Barrier Chemoprotective Mechanisms in Drosophila

The Drosophila melanogaster (Dm) humoral/CNS barrier conserves the xenobiotic exclusion properties found in the vertebrate vascular endothelium and this data indicates that the ancient origins of CNS chemoprotection extend to both conserved molecular means and functionally analogous anatomic spaces that together promote CNS selective drug partition.

In vitro models of the blood-brain barrier.

The in vitro BBB model is characterized by high transendothelial electrical resistance (TEER regularily above 200 Ohm x cm(2), low permeability and expression of several transporters, which has proven that the model is suitable for basic research and for testing the interaction between the BBB and potential drug candidates (toxicity, permeability, interaction with effluxTransporters) as well.
