Novel α-aminoamide derivatives containing different benzoheterocyclics moiety were synthesized and evaluated as voltage-gated sodium ion channels blocks the treatment of pain. Compounds 6a, 6e, and 6f containing the benzofuran group displayed more potent in vivo analgesic activity than ralfinamide in both the formalin test and the writhing assay. Interestingly, they also exhibited potent in vitro anti-Nav 1.7 and anti-Nav 1.8 activity in the patch-clamp electrophysiology assay. Therefore, compounds 6a, 6e, and 6f, which have inhibitory potency for two pain-related Nav targets, could serve as new leads for the development of analgesic medicines.

Galantamine (GAL) and curcumin (CU) are alkaloids used to improve symptomatically neurodegenerative conditions like Alzheimer's disease (AD). GAL acts mainly as an inhibitor of the enzyme acetylcholinesterase (AChE). CU binds to amyloid-beta (Aβ) oligomers and inhibits the formation of Aβ plaques. Here, we combine GAL core with CU fragments and design a combinatorial library of GAL-CU hybrids as dual-site binding AChE inhibitors. The designed hybrids are screened for optimal ADME properties and BBB permeability and docked on AChE. The 14 best performing compounds are synthesized and tested in vitro for neurotoxicity and anti-AChE activity. Five of them are less toxic than GAL and CU and show activities between 41 and 186 times higher than GAL.

Neuraminidase (NA) is an important target for current research on anti-influenza drugs. The acylhydrazone derivatives containing the -CONHN═CH- framework have been shown to have good NA inhibitory activity. In this paper, a series of novel acylhydrazone NA inhibitors (9a-9n) were designed and synthesized, and the inhibitory activities against NA were evaluated in vitro. The NA inhibition results showed that compound 9j has the most potent inhibitory activity (IC50 = 0.6 μM) against NA, which is significantly lower than that of the positive control oseltamivir carboxylic acid (OSC) (IC50 = 17.00 μM). Molecular docking analysis indicates that the acylhydrazone group plays an important role in compound 9j, which can bind well to the residues Arg371 and Arg292 in the S1 subsite of NA. The good potency of 9j may be also ascribed to the extending of morpholinyl ring into the 430-cavity. The results of this work may contribute to the development of more potent NA inhibitors to against mutant influenza viruses.
