APTS Fe2O3 Nanoparticles (Aminated ferric oxide magnetic nanoparticles) are magnetic nanomaterials modified with amino functional groups using APTS. This material consists of a ferric oxide (Fe3O4) nanoparticle core and an amino (-NH2) surface modification layer. The aminated surface helps improve the biocompatibility of the nanoparticles and reduce cytotoxicity. The amino functional groups can be further chemically modified for coupling with biomolecules such as drugs, proteins, and nucleic acids. The amino functional groups undergo protonation at different pH values, resulting in different surface charges on the nanoparticles in different pH environments.

LNO 9 is an orally active LOXL2 inhibitor and NO donor, with an IC50 of 0.17 μM against human LOXL2. LNO 9 competitively binds to the LTQ cofactor of LOXL2 to form an irreversible complex, thereby inhibiting collagen oxidation and abnormal cross-linking. LNO 9 releases nitric oxide (NO) to increase cGMP levels in pulmonary artery smooth muscle cells. LNO 9 inhibits hypoxia-induced collagen modification and possesses vasodilatory activity. LNO 9 ameliorates right ventricular hypertrophy and pulmonary artery medial thickness in rat models induced by hypoxia and Monocrotaline (HY-N0750), and can be used for research on pulmonary hypertension .

8-Oxo-dGTP (8-Oxo-Deoxyguanosine triphosphate) trisodium solution (100mM) is an oxidized guanine nucleotide formed by ROS-mediated oxidative modification of dGTP, and it also serves as a key substrate for 8-oxo-dGTP pyrophosphohydrolases (such as hMTH1 and E. coli MutT). 8-Oxo-dGTP trisodium solution (100mM) acts as a DNA mutagen, inserts into nascent DNA and pairs with adenine and cytosine, inducing A:T to C:G transversion mutations. Furthermore, 8-Oxo-dGTP trisodium solution (100mM) causes oxidative DNA base modification, strand breakage and S-phase arrest, and ultimately triggers AIF-mediated apoptosis and promotes spontaneous carcinogenesis in mth1-deficient mice. Accumulation of 8-Oxo-dGTP trisodium solution (100mM) in cells induces genomic instability, but it exhibits a tumor-suppressive effect that reduces tumor incidence in mouse models instead. 8-Oxo-dGTP trisodium solution (100mM) is widely used in studies related to spontaneous carcinogenesis, Parkinson's disease, Alzheimer's disease, heart failure and tumor mechanisms .

Carboxylated magnetic microspheres (low nonspecificity) are functionalized nano- or micron-sized magnetic particles with abundant carboxyl functional groups on their surface. Special chemical treatments reduce the likelihood of nonspecific adsorption. This 1μm carboxylated magnetic microsphere features a core-shell structure: a PS core, an outer layer of iron oxide (Fe3O4), and an outermost encapsulation layer. The carboxyl groups are obtained through polymer modification. Exhibiting low nonspecific adsorption, these microspheres can covalently couple with bioligands such as peptides, proteins, antibodies, and oligonucleotides using specific chemical reagents (e.g., EDC), making them particularly suitable for cell sorting, affinity chromatography, and immunoassay.

Aminated magnetic microspheres are superparamagnetic magnetic particles with amino functional groups modified on their surface, widely used in biomedical and molecular biology research. This 1μm aminated magnetic microsphere is composed of polystyrene and nano-iron oxide, exhibiting hydrophilicity and good biocompatibility. The aminated magnetic microspheres possess superparamagnetism, fast magnetic response, good monodispersity, ensuring reaction uniformity and detection consistency. The unique rough surface structure and polymer modification give the aminated magnetic microspheres a high amino density, allowing them to covalently couple with bioligands such as peptides, proteins, oligonucleotides, drug molecules, and glycoproteins through the action of special chemical reagents (such as glutaraldehyde). They serve as excellent coating materials and are important carrier tools in medical and biomolecular research.

Liposomes are spherical or multilayered spherical vesicles formed by the self-assembly of diacyl chain phospholipids (lipid bilayers) in aqueous solutions, which can be made from natural or synthetic phospholipids and exhibit good biocompatibility and low toxicity. They can serve as delivery carriers for various bioactive substances (such as drugs, proteins, nucleic acids, etc.) and are widely used in biomedical and chemical research. The main advantages of liposomes include 1) Protective effect: Their bilayer structure can protect encapsulated molecules from enzymatic degradation, oxidation, and other influences, extending stability and activity; 2) Active targeting: Surface modifications enable active targeting, enhancing the concentration of drugs or molecules in specific tissues or cells; 3) Customizability: The composition and structure of liposomes can be adjusted according to needs, such as altering phospholipid types or adding targeting ligands. These properties make liposomes highly valuable in developing novel drug delivery systems, serving as nucleic acid carriers for gene transfection, studying cellular uptake mechanisms and drug release kinetics, as well as developing functional food additives to improve the bioavailability of nutritional components.

MCE contains 227 liposome compounds, which is a good tool for drug delivery-related studies.
