Optimization of macromolecular prodrugs of the antitumor antibiotic adriamycin [PDF]

open access: yes, 1985
In our earlier work [10] on aminoribosyl-bound prodrugs of adriamycin (ADR) using poly(α-l-glutamic acid) (PGA) grafted in high yield (90–100 mol.%) with various peptide spacers as a plasma-soluble macromolecular carrier we observed rather low cytotoxic ...

Living Materials Approach for In Situ Bio‐Polymers Production Using Bacillus Paralicheniformis in Microneedles

open access: yesAdvanced Healthcare Materials, EarlyView.
Dissolvable microneedle (MN) device containing Bacillus paralicheniformis. The polymeric matrix encapsulates and protects the bacteria, preserving their viability while enabling in situ production and release of γ‐polyglutamic acid. The bacteria are delivered into the skin via 500 µm‐long microneedles, and remain detectable on the skin 24 h post ...

Plant volatile eliciting FACs in lepidopteran caterpillars, fruit flies and crickets: a convergent evolution or phylogenetic inheritance?

open access: yesFrontiers in Physiology, 2014
Fatty acid amino acid conjugates (FACs), first identified in lepidopteran caterpillar spit as elicitors of plant volatile emission, also have been reported as major components in gut tracts of Drosophila melanogaster and cricket Teleogryllus taiwanemma ...

Strategies to Improve the Lipophilicity of Hydrophilic Macromolecular Drugs

open access: yesAdvanced Healthcare Materials, EarlyView.
Hydrophilic macromolecular drugs can be successfully lipidized by covalent attachment of lipids, by hydrophobic ion pairing with negatively or positively charged surfactants, and by dry or wet reverse micelle formation. Lipophilicity enhancement of hydrophilic macromolecules has several benefits including stability and bioavailability improvement ...

Factors affecting protein synthesis in vitro in rabbit reticulocytes [PDF]

open access: yes, 1957
Rabbit reticulocytes in vitro rapidly incorporate labeled amino acids into their proteins. The process is accelerated by the plasma of every mammal investigated and also by extracts of normal erythrocytes, rabbit reticulocytes, liver, spleen, and yeast ...

Self‐Assembling Peptide Hydrogels Support Stromal Vascular Fraction Viability to Promote In Vivo Nerve Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Stromal vascular fraction (SVF) may enhance nerve repair, especially when delivered in a self‐assembling peptide hydrogel (SAPH). In vitro, softer SAPH increased neuronal explant outgrowth and supported greater SVF viability and proliferation. In a rat sciatic defect, SVF in an optimized SAPH produced motor and sensory recovery equivalent to autograft ...

An Ultrapotent, Ultraeconomical, Antifreeze Polypeptide

open access: yesAdvanced Materials, EarlyView.
Simple and inexpensive polypeptides composed of random copolymers of alanine and glutamic acid are effective antifreezes for applications in foods and biomedicine. The polypeptides, inspired by natural extremophile proteins, inhibit the growth of large ice crystals and prevent damage to sensitive biologics.

Biosynthesis of food constituents: Amino acids: 1. The glutamic acid and aspartic acid groups - a review

open access: yesCzech Journal of Food Sciences, 2006
This review article gives a survey of principal pathways that lead to the biosynthesis of the proteinogenic amino acids of the glutamic acid group (glutamic acid, glutamine, proline, arginine) and aspartic acid group (aspartic acid, asparagine, threonine,
