When formulated with phosphatidylcholine and exposed to aqueous media, glycerol dioleate constructs an inverted hexagonal (H_II) phase structure with sustained-release properties. The in-situ forming gel prepared by optimizing glycerol dioleate with phosphatidylcholine and N-methyl-2-pyrrolidone enables stable release of Risperidone (HY-11018) for up to 60 days in vitro and in vivo. Glycerol dioleate causes minimal side effects in rabbits, making it an ideal carrier component for the development of antischizophrenia agents .Note: Lyotropic liquid crystals (Lyotropic Liquid Crystal, LLC) are ordered fluid phases self-assembled by amphipathic molecules (e.g., lipids, surfactants) in solvents (usually water) at specific concentrations .

DOTAGA-anhydride	Radionuclide-Drug Conjugates (RDCs)	Cancer
DOTAGA-anhydride (GMP) is DOTAGA-anhydride (HY-W087187) produced by using GMP guidelines. GMP small molecules works appropriately as an auxiliary reagent for cell therapy manufacture. DOTAGA-anhydride is a DOTA-based metal chelator that can bind to radionuclides and is used to prepare radionuclide drug conjugates (RDCs). DOTAGA-anhydride has been successfully used for labeling antibodies (e.g., Trastuzumab (HY-P9907)). DOTAGA-anhydride can be used for the synthesis of a bimodal tag for Single-photon emission computed tomography (SPECT) or PET/optical imaging .
