Photosensitizer prodrug compound, and preparation method and application thereof
-
Paragraph 0105-0107, (2019/10/04)
The invention provides a photosensitizer prodrug compound, and a preparation method and an application thereof. The compound has a structure represented by formula (I). A disulfide bond is introduced at the N end of 5-ALA or its ester derivative, the disulfide bond is a GSH responsive group, the group containing the disulfide bond undergoes self-immolative reaction under the condition of linking urethane to the beta position of the disulfide bond in order to release the connected 5-ALA or its ester derivative, protoporphyrin is generated in an intracellular metabolism manner, and the photosensitizer plays a role in photodynamic diagnosis, so dimerization induced inactivation of the 5-ALA is avoided, and the drug stability is increased; and the overexpression of the GSH in various tumor cells and the response of the prodrug compound to the GSH enhance the tumor targeting property of the drug. The invention also provides the application of the photosensitizer prodrug compound in the preparation of the drug for photodynamic diagnosis and treatment.

A carbon nanosphere supported Ru (Ru-CNS) effectively catalyzed the conversion of biorenewable platform chemicals to 5-aminoleulininc acid (ALA), furan alcohols and γ-valerolactone (GVL). The catalyst exhibits high activity for the investigated processes, enabling 76% ALA and > 90% furan alcohols and GVL from their precursors. The effect of solvent polarity on the yield and selectivity of GVL and its ring-opening product has been studied with detailed characterization of the catalyst.

Twenty-seven dipeptide derivatives of general structure Ac-Xaa-ALA-OR were synthesized as potential prodrugs for 5-aminolaevulinic acid-based photodynamic therapy (ALA-PDT). Xaa is an R-amino acid, chosen to provide a prodrug with appropriately tailored l
