Parethoxycaine (Intracaine) is an ester-type local anesthetic that possesses dual activities as a non-selective inhibitor and agonist potentiator in smooth muscle, while acting as a mixed-type inhibitor of cytochrome c oxidase at the enzyme level. Parethoxycaine non-competitively inhibits the contraction of guinea pig ileal longitudinal muscle by interfering with transmembrane Ca 2+ transport (blocking K +/CD responses in an equi-effective manner), and potentiates norepinephrine (NA) responses in rat vas deferens by blocking NA uptake and promoting Ca 2+ mobilization (increasing the maximum amplitude without affecting K + responses). Parethoxycaine inhibits the activity of purified cytochrome c oxidase in a concentration-dependent manner, and can be used in research focusing on Ca 2+ signal transduction, smooth muscle contraction regulation, and mitochondrial energy metabolism .

GALA is a pH-responsive amphipathic peptide consisting of 30 amino acids, which acts as a lung endothelium-targeting ligand. GALA undergoes a conformational transition from random coil to α-helix in an acidic environment at pH 5.0, thereby inducing endosomal membrane destabilization and fusion. GALA-modified liposomes traverse lung endothelial cells via clathrin-dependent endocytosis and transcytosis, and specifically accumulate in the lungs after intravenous injection. GALA significantly promotes the cytosolic release of cargos carried by exosomes, plasmids and liposomes, effectively enhances gene transfection efficiency, and drives gene knockdown of functional macromolecules (such as siRNA) in alveolar epithelial cells (with no significant cytotoxicity at effective concentrations). GALA serves as a critical tool for studies on lung cancer metastasis (e.g., melanoma lung metastasis) and lung-targeted drug delivery systems .
