A general and flexible synthetic route, which leads to the synthesis of brazilin-like compounds, was developed. The aza-brazilin derivatives show strong anticancer activities in MTT assay towards a number of human cancer cell lines including HT29, A549, HL60, and K562.
Amyloid beta (A beta) and cholinesterase enzymes (AChE, BuChE) are important biological targets for the effective treatment of Alzheimer's disease. In this study, the aim was to synthesize new donepezil-like secondary amide compounds that display a potent inhibition of cholinesterases and A beta with antioxidant and metal chelation abilities. All test compounds showed activities against both ChEs and beta(1-42) inhibition. The most encouraging compound, 20, is an AChE inhibitor with high anti-aggregation activity (55.3%). Based on the results, compound 20 may be a promising structure in further research for new anti-Alzheimer's agents. (C) 2015 Elsevier Ltd. All rights reserved.
Design, synthesis and biological activity of 1H-indene-2-carboxamides as multi-targeted anti-Alzheimer agents
to design new molecules and evaluate their anticholinesterase and amyloid beta (Aβ1-42) inhibition activities as multifunctional drug candidates for the treatment of Alzheimer's disease (AD). A series of 5,6-dimethoxy-1H-indene-2-carboxamides (1-22) was synthesized; cholinesterase inhibitory activities of the compounds were measured according to Ellman's colorimetric assay, while the thioflavin T assay

The synthesis of a series of novel aza-brazilan derivatives containing imidazolium salt pharmacophores is presented. The biological activity of such imidazolium salts was further evaluated in vitro against a panel of human tumor cell lines. The results suggest that the electron-withdrawing group on the aza-brazilan moiety, substituted 5,6-dimethyl-benzimidazole ring and substitution of the imidazolyl-3-position
