The recovery process following ischemic stroke is a complex undertaking involving intricate cellular and molecular interactions. Cellular dysfunction or aberrant pathways can lead to complications such as brain edema, hemorrhagic transformation, and glial scar hyperplasia, hindering angiogenesis and nerve regeneration. These abnormalities may contribute to long-term disability post-stroke, imposing significant burdens on both families and society. Current clinical interventions primarily focus on endovascular therapy, overlooking the protection of brain cells themselves. However, the use of bioactive materials in stroke management has shown notable safety and efficacy. By precisely targeting the ischemic site at a cellular and molecular level, this therapeutic approach mitigates ischemia-induced brain tissue damage and promotes site repair. This review examines the protective benefits of bioactive materials in reducing cell damage and facilitating nerve restoration in accordance with the pathophysiological basis of ischemic stroke. Enhanced understanding of ischemic stroke mechanisms has the potential to advance the targeted and efficient clinical use of bioactive materials.

Here, we report on the synthesis and biological evaluation of a novel peptide-drug conjugate, P6-SN38, which consists of the EGFR-specific short cyclic peptide, P6, and the Topo I inhibitor SN38, which is a bioactive metabolite of the anticancer drug irinotecan. SN38 is attached to the peptide at position 20 of the E ring's tertiary hydroxyl group via a mono-succinate linker. The developed peptide-drug conjugate (PDC) exhibited sub-micromolar anticancer activity on EGFR-positive (EGFR+) cell lines but no effect on EGFR-negative (EGFR-) cells.

Artificial blood vessels made from polyurethane (PU) have been researched for many years but are not yet in clinical use. The main reason was that the PU materials are prone to degradation after contact with blood and will also cause inflammation after long-term implantation. At present, PU has made progress in biostability and biocompatibility, respectively.

Agro-industrial residues have transitions from being an environmental problem to being a cost-effective source of biopolymers and value-added chemicals. However, the efficient extraction of the desired products from these residues requires pretreatments. Fungal biorefinery is a fascinating approach for the biotransformation of raw materials into multiple products in a single batch.
