Alzheimer's Disease (AD) is one of the major health crises in the 21st century, and due to the complexity of its pathogenesis, there has no good solution to cure this disease. In order to find more economical and effective drugs for the treatment of neurodegenerative diseases, a series of novel 2-dehydroepiandrosterone benzathine derivatives were synthesized and their activity on the NO release of microglia cell line BV-2 activated by lipopolysaccharide (LPS), as well as their effect on cell viability were studied. The structures of the synthesized compounds were confirmed by 1H NMR, 13C NMR and HRMS. The results showed that all compounds had inhibitory effects on the NO release of LPS-activated mouse microglial cell line BV2 after 24 h of treatment, and it was dose-dependent. In particular, the IC50 values of 2-(3-chloro)benzylidene-15β,16β-methylene-androstane-4,6-diene-3,17-dione (5a) and 2-(3,4,5-trimethoxy)benzylidene-15β,16β-methylene-androstane-4,6-die-ne-3,17-dione (5j) were 2.69 and 3.28 μmol·L-1, respectively, which were better than the positive control Minocycline. The results showed that these compounds may be effective in the development of neurodegenerative diseases involving activation of microglia, and the mechanism deserved further study.
