Sequential Design of Activatable Photosensitizers for Ablation of Glioma Cells in Brain Cancer Tissues

open access: yesAngewandte Chemie, EarlyView.
Gal‐SeNBD‐oleamide is an activatable photosensitizer (PS) with efficient uptake and selective, β‐galactosidase‐triggered activation in cancer cells, enabling efficient photodynamic ablation of glioma cells directly in brain tissue slices from mouse preclinical models and human glioblastoma patients.

5-Aminolevulinic acid: A matter of life and caveats

open access: yesJournal of Photochemistry and Photobiology, 2021
Our mini-review concerns the potential adverse pro-oxidant role of 5-aminolevulinic (ALA), the first protoporphyrin IX (PP-IX)/heme precursor widely used in commercial formulations for endogenous photodynamic therapy (PDT).

5-Aminolevulinic acid synthesis in Escherichia coli [PDF]

open access: yesJournal of Bacteriology, 1989
A hemA mutant of Escherichia coli containing a multicopy plasmid which complemented the mutation excreted 5-aminolevulinic acid (ALA) into the medium. [1-14C]glutamate was substantially incorporated into ALA by this strain, whereas [2-14C]glycine was not. Periodate degradation of labeled ALA showed that C-5 of ALA was derived from C-1 of glutamate. The

X-ray structure of a putative reaction intermediate of 5-aminolaevulinic acid dehydratase

open access: yes, 2003
The X-ray structure of yeast 5-aminolaevulinic acid dehydratase, in which the catalytic site of the enzyme is complexed with a putative cyclic intermediate composed of both substrate moieties, has been solved at 0.16 nm (1.6 Å) resolution.

Photodynamic diagnosis for skull invasion [PDF]

open access: yes, 2008
OBJECTIVE: We present a case of a meningioma in which photodynamic diagnosis (PDD) using 5-aminolevulinic acid was very useful in identifying the cranial involvement. CLINICAL PRESENTATION: An 83-year-old woman presented with a bony, hard, immobile bulge

Beyond a dual role: how Purpureocillium lilacinum reprograms citrus metabolism for integrated biocontrol and growth promotion

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Plants harbor complex microbial communities that are fundamental to their health and productivity. Among them, endophytic fungi such as Purpureocillium lilacinum establish mutualistic associations, offering dual benefits as plant growth promoters and biocontrol agents.
