Abstract:
:A newly designed curcumin mimic library (11a-11k) with 2-ethylamino groups in a chalcone structure and variously substituted triazole groups as side chains was synthesized using the Huisgen 1,3-cycloaddition reaction between various alkynes (a-k) and an intermediate (10), with CuSO4 and sodium ascorbate in a solution mixture of chloroform, ethanol, and water (5:3:1) at room temperature for 5h. In the lactate dehydrogenase (LDH) release assay involving co-treatment with tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) and/or synthetic curcumin derivatives using TRAIL-resistant human CRT-MG astroglioma cells, the novel curcumin mimic library was found to effectively stimulate the cytotoxicity of TRAIL, causing mild cytotoxicity when administered alone. In particular, 11a and 11j are promising candidates for TRAIL-sensitizers with potential use in combination chemotherapy for brain tumors.
