What chemo can cross the blood brain barrier?

Which drugs can easily cross the blood-brain barrier?

Small, lipid-soluble agents, such as antidepressants, cross the BBB via diffusion through endothelial cells. 3. Specialised transport proteins transport glucose, amino acids, and drugs like vinca alkaloids and cyclosporin, across the BBB.

Which anticancer drug can cross blood-brain barrier?

Table 2

Drug Family CSF/Plasma Ratio (%) Ref
Erlotinib 1 [61]
Icotinib 0.7 [61]
Imatinib 5 [62]
Osimertinib >100 (brain/plasma ratio) [63]

Can cancer cross the blood-brain barrier?

Cancer cells traveling through the bloodstream eventually colonize a vascular place, by adhering to endothelial cells, or cross the brain barrier to begin the process that leads to the niche formation in the brain parenchyma.

What Cannot cross the blood-brain barrier?

Such substances include lipid-soluble substances (e.g., oxygen, carbon dioxide). Hydrophilic substances, for example, hydron and bicarbonate, are not permitted to pass through cells and across the blood-brain barrier.

Can CBD cross the blood-brain barrier?

CBD, while not psychotropic, also modulates immune function, but its mechanism of action appears to differ from that of THC. Since both compounds are highly lipophilic, they readily passage the blood-brain barrier and access the central nervous system.

Does ifosfamide cross the blood-brain barrier?

IFO and IPM cross the blood–brain barrier and IPM concentrations in the CSF are even higher than in plasma. IFO neurotoxicity can occur following its metabolism to CAA, but the incidence is low, particularly when IFO is administered by continuous intravenous infusion.

Do chemo drugs cross the blood-brain barrier?

This barrier makes it hard for some substances (such as anticancer drugs) to enter the brain. It prevents many chemotherapy drugs from reaching brain tumour cells in large enough amounts to destroy them. The chemotherapy drugs used to treat brain tumours must be able to cross the blood-brain barrier.

Does vinblastine cross the blood-brain barrier?

The results suggest that additional factors, such as steric hindrance and molecular charge distribution, related to the chemical and geometric structure and the large size of vincristine and vinblastine (molecular weight, 825 and 814 daltons, respectively) restrict their passage across the blood-brain barrier.

Why can a drug cross the blood-brain barrier?

The BBB is anatomically and functionally distinct from the blood–cerebrospinal fluid barrier at the choroid plexus. Certain small molecule drugs may cross the BBB via lipid-mediated free diffusion, providing the drug has a molecular weight <400 Da and forms <8 hydrogen bonds.

What does blood-brain barrier mean?

A network of blood vessels and tissue that is made up of closely spaced cells and helps keep harmful substances from reaching the brain. The blood-brain barrier lets some substances, such as water, oxygen, carbon dioxide, and general anesthetics, pass into the brain.
