So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Bhattacharyya, Jayanta; Weitzhandler, Isaac; Ho, Shihan Bryan; McDaniel, Jonathan R.; Li, Xinghai; Tang, Lei; Liu, Jinyao; Dewhirst, Mark; Chilkoti, Ashutosh researched the compound: 1-(tert-Butyl)-1H-pyrrole-2,5-dione( cas:4144-22-3 ).Category: chlorides-buliding-blocks.They published the article 《Encapsulating a Hydrophilic Chemotherapeutic into Rod-Like Nanoparticles of a Genetically Encoded Asymmetric Triblock Polypeptide Improves Its Efficacy》 about this compound( cas:4144-22-3 ) in Advanced Functional Materials. Keywords: peptide gemcitabine conjugate antitumor tumor maleimide derivative; asymmetric triblock polypeptide; colon cancer; gemcitabine; hydrophilic drug delivery; nanoparticle. We’ll tell you more about this compound (cas:4144-22-3).
Encapsulating hydrophilic chemotherapeutics into the core of polymeric nanoparticles can improve their therapeutic efficacy by increasing their plasma half-life, tumor accumulation, and intracellular uptake, and by protecting them from premature degradation To achieve these goals, a recombinant asym. triblock polypeptide (ATBP) that self-assembles into rod-shaped nanoparticles, and which can be used to conjugate diverse hydrophilic mols., including chemotherapeutics, into their core is designed. These ATBPs consist of three segments: a biodegradable elastin-like polypeptide, a hydrophobic tyrosine-rich segment, and a short cysteine-rich segment, that spontaneously self-assemble into rod-shaped micelles. Covalent conjugation of a structurally diverse set of hydrophilic small mols., including a hydrophilic chemotherapeutic-gemcitabine-to the cysteine residues also leads to formation of nanoparticles over a range of ATBP concentrations Gemcitabine-loaded ATBP nanoparticles have significantly better tumor regression compared to free drug in a murine cancer model. This simple strategy of encapsulation of hydrophilic small mols. by conjugation to an ATBP can be used to effectively deliver a range of water-soluble drugs and imaging agents in vivo.
