ZIF-8 (2-Methylimidazole zinc salt) is a pyroptosis inducer that activates the caspase-1/gasdermin D-dependent pyroptosis pathway. ZIF-8 induces pyroptotic cell death accompanied by necrosis and immunogenic cell death. ZIF-8 initiates in situ immunity, activates anti-tumor immunity, and reprograms the immunosuppressive tumor microenvironment to inhibit tumor growth. ZIF-8 acts as a pH-responsive and stimulus-responsive drug release inducer. ZIF-8 is applicable to cancer-related research .

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 .

OF-02 is an ionizable lipid for mRNA delivery and a key component of lipid nanoparticles (LNPs). OF-02 is protonated in the acidic endosomal environment to promote endosomal escape of mRNA and efficiently induce protein expression in target cells. OF-02 relies on the pH-responsive membrane fusion properties to form a complex with mRNA and destroy the endosomal membrane structure to achieve mRNA release in the cytoplasm. OF-02 is mainly used in the development of mRNA vaccines, gene editing, and protein replacement therapy[1][2][3].

Fluorescein O-methacrylate (Methacryloyloxy fluorescein) is a pH-responsive fluorescent monomeric dye. Fluorescein O-methacrylate exhibits pH-responsive fluorescence properties: its fluorescence is activated under alkaline conditions and quenched under neutral or acidic conditions; reversible switching of fluorescence is achievable by adjusting the pH of the solution. Fluorescein O-methacrylate can be used as a monomer for the synthesis of amphiphilic fluorescein polymers. These polymers can self-assemble into stable polymer nanoparticles with enhanced aqueous-phase fluorescence, and also enable the conjugation of nanoparticles with amine-containing biomolecules to support sensitive optical detection of biomarkers (Ex/Em = 490/520 nm) .

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 .

RALA peptide is a cationic amphiphilic delivery agent targeting cell membranes, which forms nanoparticles through electrostatic interactions with anionic drugs. RALA peptide has pH-responsive binding properties, which can enhance the α-helical conformation in an acidic environment and destroy the endosomal membrane, promote the release of drugs into the cytoplasm, and exert efficient intracellular delivery activity. RALA peptide can be used in cancer research (enhancing the activity of bisphosphonates against prostate cancer and breast cancer cells) and bone tissue engineering (promoting osteoblast collagen deposition and extracellular matrix mineralization) .

GALA-chol is a cholesterol-conjugated pH-responsive fusion peptide that can serve as a delivery adjuvant. GALA-chol enhances the endocytosis of siRNA RET/PTC1-SQ nanoparticles, inhibits cell viability, and undergoes pH-responsive charge conversion in the acidic lysosomal environment, thereby promoting lysosomal escape of small extracellular vesicle (sEV) cargo. GALA-chol anchors to the sEV membrane and maintains the structural integrity and intrinsic homing activity of sEVs. GALA-chol can be used in studies related to adjuvant delivery .

LH2 peptide is a pH-responsive cell-penetrating peptide dimer with the amino acid sequence LHHLCHLLHHLCHLAG. It can increase its uptake in tumor cells under weakly acidic conditions (such as the tumor microenvironment) through the protonation of histidine residues (pKa approximately 6). When conjugated with the anticancer drug Paclitaxel (HY-B0015), the PTX-LH2 conjugate showed superior tumor suppression effects compared to paclitaxel alone in a subcutaneous breast tumor model. The LH2 peptide holds potential as a drug delivery vehicle in cancer research .

GALA-Cys is a chemically modified GALA peptide (HY-P5423) that retains GALA functions while acquiring strong covalent conjugation capability. GALA-Cys undergoes pH-driven reversible secondary structure transition, rearranges into an amphipathic α-helix, self-oligomerizes, penetrates lipid membranes to form pores, and disrupts lipid bilayers, thereby enabling endosomal escape and cytosolic cargo delivery. GALA-Cys can be conjugated with lipid DPTE for integration into liposomes, self-assembles into a tilted monolayer on gold surfaces, and serves as a pH-responsive coating for particle surface functionalization. GALA-Cys is applicable to studies related to targeted cargo delivery .

OF-02 is an ionizable lipid for mRNA delivery and a key component of lipid nanoparticles (LNPs). OF-02 is protonated in the acidic endosomal environment to promote endosomal escape of mRNA and efficiently induce protein expression in target cells. OF-02 relies on the pH-responsive membrane fusion properties to form a complex with mRNA and destroy the endosomal membrane structure to achieve mRNA release in the cytoplasm. OF-02 is mainly used in the development of mRNA vaccines, gene editing, and protein replacement therapy[1][2][3].
