A Highly Efficient Tumor‐Targeting Nanoprobe with a Novel Cell Membrane Permeability Mechanism

Advances in Materials, 2019
Efficient tumor targeting has been a great challenge in the clinic for a very long time. The traditional targeting methods based on enhanced permeability and retention (EPR) effects show only an ≈5% targeting rate.

Measurement of membrane permeability and the mitochondrial permeability transition

2020
The mitochondrial permeability transition (PT) is an increase in the inner membrane permeability caused by the opening of a Ca2+-activated high-conductance channel, the so-called PT pore (PTP) or mitochondrial megachannel (MMC). Recent data indicate that F-ATP synthase contributes substantially to the generation of the PTP, yet this hypothesis is the ...

Permeability of the Synovial Membrane to Proteins

Acta Rheumatologica Scandinavica, 1963
SummaryThe normal synovial membrane has been shown to be only slightly permeable to proteins, especially certain glycoproteins. After filtration of serum through a hyaluronic acid gel in vitro a protein profile similar to that of normal synovial fluid is obtained.

Factors Affecting the Membrane Permeability Barrier Function of Cells during Preservation Technologies.

Langmuir, 2018
Cellular membranes are exposed to extreme conditions during the processing steps involved in cryopreservation (and freeze-drying) of cells. The first processing step involves adding protective agents.

Measurement of Membrane Permeability and the Permeability Transition of Mitochondria

2007
Publisher Summary This chapter focuses on the experimental procedures designed to measure apoptosis-associated mitochondrial membrane permeabilization, either in intact cells or in isolated mitochondria. Following a variety of death signals, mitochondria show early alterations in their function that at least in some instances may be explained by the ...

Interconversion Rates between Conformational States as Rationale for the Membrane Permeability of Cyclosporines.

ChemPhysChem, 2017
Cyclic peptides have regained interest as potential inhibitors of challenging targets but have often a low bioavailability. The natural product cyclosporine A (CsA) is the textbook exception.

Improving the Membrane Permeability of 5-Fluorouracil via Cocrystallization

, 2016
Pharmaceutical cocrystallization is proposed as a new method to enhance membrane permeability of a BCS class III model drug, 5-fluorouracil (5FU). Three cocrystals of 5FU, 5FU/3-hydroxybenzoic acid (1), 5FU/4-aminobenzoic acid (2), and 5FU/cinnamic acid (

Passive Membrane Permeability in Cyclic Peptomer Scaffolds Is Robust to Extensive Variation in Side Chain Functionality and Backbone Geometry.

Journal of Medicinal Chemistry, 2016
Synthetic and natural cyclic peptides provide a testing ground for studying membrane permeability in nontraditional drug scaffolds. Cyclic peptomers, which incorporate peptide and N-alkylglycine (peptoid) residues, combine the stereochemical and ...

The engineering of membrane-permeable peptides

Analytical Biochemistry, 2005
Reversible lipid attachment was investigated as a means to deliver small peptides into cells. Two labile straight chain alkyl motifs were developed: a cysteine dodecane disulfide (Cdd) building block and a tyrosine- or serine-myristate ester. Both moieties are cleaved on cell internalization and are compatible with Fmoc solid phase peptide synthesis. A
