A total of 26 compounds based on osthole skeleton were designed, synthesized. Their cytoprotective abilities of antioxidation, anti-inflammation and Aβ42(Amyloid β-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 Aβ42 (61.4 ± 5.2%) at a low concentration of 10 μM. 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 Aβ 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.

Objective: The present work deals with the designing, scoring, synthesis and, characterization of 1-(4-(2-(4-Substitutedphenylamino)-2-oxoethyl)phenylsulfonyl)-3-(4-substitutedbenzoyl)urea (5A-5B),1-(4-(2-(4-substitutedphenylamino)-2-oxoethyl)phenylsulfonyl)-3-(4-substituted-benzoyl)guanidine(5C-5E) and, 1-(4-Substitutedbenzoyl)-3-(4-(2-oxo-2-(piperazin-1-yl)ethyl)phenylsulfonyl)urea (5F-5H) based derivatives as hypoglycemic agents. Methods: Docking calculations were performed to predict the binding affinity between the AKR1C1 complexes and sulphonylureas compounds using the Glide docking program. Docking studies on LigPrep treated ligands were carried out to predict the binding pocket of protein 4YVP using the docking program. The QikProp program was used to predict the ADME/T properties of the analogues. All these newly synthesized compounds were screened for their in vivo hypoglycemic activity by most relevant animal models like alloxan-induced diabetic rats by measuring blood plasma concentration compared with reference drug glibenclamide. Results: Novel compounds 1-(4-(2-(4-Substitutedphenylamino)-2-oxoethyl)phenylsulfonyl)-3-(4-substitutedbenzoyl)urea (5A-5B), 1-(4-(2-(4-substitutedphenylamino)-2-oxoethyl)phenylsulfonyl)-3-(4-substitutedbenzoyl) guanidine (5C-5E), and 1-(4-Substitutedbenzoyl)-3-(4-(2-oxo-2-(piperazin-1-yl)ethyl)phenylsulfonyl)urea (5F-5H) were synthesised and characterized using spectral and analytical data. The results of molecular docking and in vivo hypoglycemic activity, all compounds have shown considerable activity with respect to glibenclimide, but compounds 5D (52.49±7.73) and 5E(48.18±4.22)are equipotent with respect to activity as compared to standard glibenclamide(55.97±3.19). Conclusion: Compounds 5D and 5E have exhibited good hypoglycemic activity,hence both the derivatives will consider as a lead molecule and further some modification in their structures to get a more potent anti-diabetic agent.
