Category: chiral-nitrogen-ligands. 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. Compound: 1,5-Dibromopentane, is researched, Molecular C5H10Br2, CAS is 111-24-0, about Acetylcholinesterase inhibition of diversely functionalized quinolinones for alzheimer’s disease therapy.
The synthesis and cholinesterase (ChE)/monoamine oxidase (MAO) inhibition of quinolinones I [R = 2-diethylaminoethyl, 1-methyl-4-piperidyl, 3-morpholinopropyl, etc.] and dihydroquinolinones II [R1 = 1-methyl-4-piperidyl, 2-morpholinoethyl, 2-(4-isopropylpiperazin-1-yl)ethyl, etc.] designed as potential multitarget small mols. (MSM) for alzheimer’s disease therapy was reported.. None of them showed significant human recombinant MAO inhibition, but compounds I [R = 4-(4-isopropylpiperazin-1-yl)butyl, 5-(4-isopropylpiperazin-1-yl)pentyl] and compound II [R1 = 4-(4-isopropylpiperazin-1-yl)butyl] displayed promising human recombinant acetylcholinesterase (hrAChE) and butyrylcholinesterase (hrBuChE) inhibition. In particular, compound I [R = 4-(4-isopropylpiperazin-1-yl)butyl] was found to be a potent and quite selective non-competitive inhibitor of hrAChE (IC50 = 0.29μM), with Ki value in nanomolar range (79 nM). Pertinent docking anal. confirmed this result, suggesting that this ligand was an interesting hit for further investigation.
There is still a lot of research devoted to this compound(SMILES：BrCCCCCBr)Category: chiral-nitrogen-ligands, and with the development of science, more effects of this compound(111-24-0) can be discovered.
