Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Product Details of 111974-74-4, 111974-74-4, Name is 11-(1-Piperazinyl)-dibenzo[b,f][1,4]thiazepine dihydrochloride, molecular formula is C17H19Cl2N3S, belongs to piperazines compound. In a document, author is Zhang, Li, introduce the new discover.
Design, synthesis and biological evaluation of novel osthole-based derivatives as potential neuroprotective agents
A total of 26 compounds based on osthole skeleton were designed, synthesized. Their cytoprotective abilities of antioxidation, anti-inflammation and A beta(42)(Amyloid beta-protein 42)-induced neurotoxicity were evaluated by MTT assays. Mechanism of the action of selected compounds were investigated by molecular docking. AlogP, logS and blood-brain barrier (BBB) permeability of all these compounds were simulated by admetSAR. Most of the compounds showed better antioxidative and anti-inflammatory activities compared with osthole, especially OST7 and OST17. The compound OST7 showed relative high activity in neuroprotection against H2O2 (45.7 +/- 5.5%), oxygen glucose deprivation (64.6 +/- 4.8%) and A beta(42) (61.4 +/- 5.2%) at a low concentration of 10 mu M. EC50 of selected compounds were measured in both H2O2 and OGD induced cytotoxicity models. Moreover, NO inhibiting ability of OST17(50.4 +/- 7.1%) already surpassed the positive drug indomethacin. The structure activity relationship study indicated that introduction of piperazine group, tetrahydropyrrole group and aromatic amine group might be beneficial for enhancement of osthole neuroprotective properties. Molecular docking explained that the reason OST7 exhibited relatively stronger neuroprotection against A beta because of the greater area of interactions between molecule and target protein. OST7 and OST17 both provided novel methods to investigate osthole as anti-AD drugs.
