Zhou, Qinghao;Mohammed, Fathelrahman;Wang, Yuheng;Wang, Jingbo;Lu, Nannan;Li, Junjie;Ge, Zhishen research published 《 Hypoxia-responsive block copolymer polyprodrugs for complementary photodynamic-chemotherapy》, the research content is summarized as follows. The inherent hypoxic microenvironment of solid tumors has an important influence on tumor growth, distant metastasis, and invasiveness. The heterogeneous distribution of hypoxic regions inside tumors limits the therapeutic efficacy of O2-assisted therapeutic strategy (e.g. photodynamic therapy (PDT)). On the other hand, the hypoxia-activable prodrugs cannot work effectively in the regions with enough O2 concentration To address the issues, we prepare a block copolymer polyprodrug consisting of polyethylene glycol (PEG) and copolymerized segments of nitroimidazole-linked camptothecin (CPT) methacrylate and 5,10,15,20-tetraphenylporphyrin (TPP)-containing methacrylate monomers for complementary photodynamic-chemotherapy. The polyprodrug can self-assemble into polymeric micelles in aqueous solution with suitable size and high stability. After i.v. injection, the polyprodrug micelles show tumor accumulation. Followed by light irradiation (650 nm) at tumor sites, TPP moieties induce singlet oxygen (1O2) production in the oxygen-rich area to exert PDT and cause transformation of the oxygen-rich areas into hypoxia. Simultaneously, in the hypoxic areas, the hypoxia-responsive polyprodrugs can be activated to release free CPT due to the cleavage of nitroimidazole linkages. The polyprodrug micelles with the segments for PDT and hypoxia-activable CPT efficiently suppress the growth of HeLa tumors. The well-defined polyprodrug amphiphiles offer an effective strategy to overcome the disadvantages of single treatment of PDT or hypoxia-responsive prodrugs for complementary photodynamic-chemotherapy of cancers.
Reference of 3034-50-2, 1H-Imidazole-4-carbaldehyde, also known as 1H-Imidazole-4-carbaldehyde, is a useful research compound. Its molecular formula is C4H4N2O and its molecular weight is 96.09 g/mol. The purity is usually 95%.
The starting material for a practical synthesis of a potent C17,20-lyase inhibitor. The lyase is a key enzyme in androgen biosynthesis as well as a target for treatment of androgen-dependent prostate cancer. Used to synthesize potent antimalarial drug.
1H-Imidazole-4-carbaldehyde is a chemical compound that has been shown to bind to the glucocorticoid receptor. It was synthesized by reacting 1,2-diaminobenzene with formaldehyde and then hydrolyzing the intermediate imidazolium salt, which is stable in acidic solutions. The complex can be prepared by mixing two solutions of imidazole and trifluoroacetic acid. The ligand has a redox potential of -0.1 V (vs NHE). This means it can be oxidized to the carbonyl group or reduced back to the imidazole ring. The compound is stable in neutral solution and forms stable complexes with metal ions such as Cu+, Fe3+, and Zn2+. It also coordinates well with oxygen atoms, nitrogen atoms, and water molecules. 1H-Imidazole-4-carbaldehyde has been shown to bind to glucocortic, 3034-50-2.
