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) .

1-Pyrenebutyric acid is a pyrene-based fluorescent probe compound. The fluorescence lifetime of 1-Pyrenebutyric acid is quenched by molecular oxygen and intracellular ROS, thus it serves as a fluorescent probe for detecting ROS and oxygen concentration through fluorescence lifetime measurements. 1-Pyrenebutyric acid undergoes electrostatic interactions with arginine-rich peptides, increasing their net hydrophobicity, promoting their direct translocation across lipid bilayers, and enhancing cytosolic delivery. 1-Pyrenebutyric acid is used for intracellular reactive oxygen species detection and research related to arginine-rich peptide-mediated cytosolic delivery .

Synonyms: Sodium stearyl sulfate
Sodium octadecyl sulfate (Sodium stearyl sulfate) is a long-chain alkyl sodium sulfate that functions as an emulsifier, crosslinking agent, and regulator. Sodium octadecyl sulfate has high safety, with a LD50 greater than 3.00 Gm./Kg for both intraperitoneal injection in mice and oral administration in rats. Sodium octadecyl sulfate enhances continuous contraction of the gastrocnemius muscle in frogs and boosts intestinal smooth muscle activity in albino rats. However, Sodium octadecyl sulfate exerts no significant effect on isolated tortoise myocardium and does not alter the conduction function of frog sciatic nerves. Sodium octadecyl sulfate can also be used to coat the surface of starch aggregates, promote crosslinking and increase aggregate size through hydrophobic and electrostatic interactions, and further form a coexistent B-V type crystalline structure with acid-hydrolyzed gelatinized starch, thereby effectively modifying the structure and surface properties of high-starch systems .

tBu2bpy is a bidentate nitrogen ligand that coordinates with Pt (II) and Pt (IV) to form functional complexes. The tBu2bpy Pt (II) bis-crown ether complex selectively recognizes Mg 2+ and Zn 2+; both ions significantly enhance the fluorescence of the complex and cause a blue shift of the absorption peak. Its six-coordinate Pt (IV) complex [Pt (X)2Me2 ( tBu2bpy)] inhibits the proliferation of tumor cells. tBu2bpy Pt (IV) complexes bind to DNA through multiple interactions including partial intercalation, groove binding, and electrostatic interaction, and can competitively displace ethidium bromide and covalently bind to purine nucleotides. tBu2bpy can be used in relevant research in fields such as organic synthesis .
