Synonyms: LPS, from Pseudomonas aeruginosa (10)
Lipopolysaccharides from P. aeruginosa (Pseudomonas aeruginosa) 10 are lipopolysaccharide endotoxins and TLR4 activators derived from Pseudomonas aeruginosa 10, and are classified as S-type LPS. Lipopolysaccharides from P. aeruginosa 10 exhibit a typical three-part structure: O-antigen, core oligosaccharide, and lipid A. The lipopolysaccharides of P. aeruginosa 10 have a fatty acid composition distinct from common enterobacteria, an exceptionally high degree of phosphorylation (triphosphate residues have been detected), and a unique outer region of the core oligosaccharide. Additionally, their O-specific side chains are typically rich in novel aminosugars. Lipopolysaccharides from P. aeruginosa 10 demonstrate susceptibility to viruses, with the level of susceptibility determined by the content of high molecular weight polysaccharides in their composition. The absence of high molecular weight polysaccharides increases their sensitivity to bacteriophages .

NH2-UAMC1110 is an aminobutoxy derivative of the fibroblast activation protein (FAP) inhibitor UAMC1110 (HY-100684), and is a precursor compound for the synthesis of FAP inhibitor probes, not directly used in bioactivity experiments. For example, NH2-UAMC1110 is involved in the synthesis of the radiotracer FAPI-QS, which exhibits high tumor selectivity and high dose-response, and has been used for tumor diagnosis. NH2-UAMC1110 introduces an active amino group into its structure, enabling it to form covalent bonds with various molecules (such as DOTA, DATA5m, radionuclide chelators, etc.), thereby synthesizing molecular imaging probes or targeted compounds with the ability to target FAP. NH2-UAMC1110 specifically binds to the FAP active site, inhibiting its proline-selective serine protease activity (including dipeptidyl peptidase and endopeptidase activity), blocking FAP-mediated tissue remodeling processes. Its key activity is high targeting and high affinity, and its core function is to be coupled with bifunctional chelators (such as DOTA, DATA5m) as a targeting module. NH2-UAMC1110 can be applied to diagnostic imaging studies of tumors expressing FAP (such as colorectal cancer, pancreatic cancer, etc.), and also provides molecular tools for targeted research of FAP-related diseases with high FAP expression, such as fibrosis and arthritis .
