    We herein applied the four step-synthetic route to prepare the pyridazine core attached to the various N-aryl acetamides. By this approach, a new series of pyridazine-based compounds were synthesized, characterized and evaluated for their activities against α-glucosidase enzyme. In-vitro α-glucosidase assay established that twelve compounds are more potent than acarbose. Compound 7a inhibited α-glucosidase
    我们在此应用了四步合成路线来制备与各种N-芳基乙酰胺连接的哒嗪核心。通过这种方法,合成了一系列新的基于哒嗪的化合物,表征并评估了它们对α-葡萄糖苷酶的活性。在-体外α葡糖苷酶测定法确定,12个的化合物比阿卡波糖更有效。化合物7a抑制α-葡萄糖苷酶,IC 50值为70.1 µM。最有效的化合物对HDF细胞系无细胞毒性。进行了分子对接和动力学研究,以确定相互作用和抑制的模式。

    than the clinically used drug, acarbose. The kinetic study revealed the competitive inhibition behavior of compound 5m (Ki = −56 μM). Docking studies showed imperative interactions such as hydrogen bonding, Pi-Pi T-shaped, and Pi-anion interactions confirming the observed activity. The RMSD value was determined less than 3 Å and validated the study. Graphical Abstract

    Reaction of 5,6-diphenylpyridazin-3(2H)-one 1a,b with 2,3,4,6-tetra-O-acetyl--D-glucopyranosyl bromide 2 in K2CO3/acetone gave 5,6-diphenyl-N2-(2',3',4',6'-tetra-O-acetyl--D-glucopyranosyl)pyridazin-3-one 5a,b. The same nucleosides 5a,b were obtained by reaction of 1a,b with peracetylated glucose 3 under MW irradiation. Mercuration of 1a,b followed by reaction with glucosyl bromide 2 gave the same nucleosides 5a,b. The riboside 4-cyano-5,6-diphenyl-N2-(2',3',5'-tri-O-acetyl--D-ribofuranosyl)-pyridazin-3-one 8 was obtained by reaction of 4-cyanopyridazinone 1b with peracetylated ribose 7 under MW irradiation. The deprotected nucleosides 6a,b and 9 were obtained by stirring of 5a,b and 8 in methanol and TEA/H2O. The structure was confirmed using 1H and 13C-NMR spectra. Selected members of these compounds were screened for antibacterial activity.
