Structure-based design of rhodanine-based acylsulfonamide derivatives as antagonists of the anti-apoptotic Bcl-2 protein
摘要:
A series of novel rhodanine-based acylsulfonamide derivatives were designed, synthesized, and evaluated as small-molecule inhibitors of anti-apoptotic Bcl-2 protein. These compounds exhibit potent antiproliferative activity in three human tumor cell lines (Hep G2, PC-3 and B16-F10). Among them, the most potent compounds 10 and 11 bind to Bcl-2 with a K-i of 20 and 25 nM, respectively. Docking studies demonstrated that these two compounds orient similarly at the binding site of Bcl-2, and the calculated binding affinities (Glide XP score) of compound 10 is more negative than that of compound 11. The binding interactions of compounds with high binding affinity to Bcl-2 protein were analyzed. (C) 2012 Elsevier Ltd. All rights reserved.
A series of rhodanine derivatives was prepared. The synthetic approach, analytical and spectroscopic data of all synthesized compounds are presented. Lipophilicity of all the discussed rhodanine derivatives was analyzed using the RP-HPLC method. The compounds were tested for their ability to inhibit photosynthetic electron transport (PET) in spinach (Spinacia oleracea L.) chloroplasts and reduce chlorophyll content in freshwater alga Chlorella vulgaris. Structure-activity relationships between the chemical structure, physical properties and biological activities of the evaluated compounds are discussed. For majority of the tested compounds the lipophilicity of the compound and not electronic properties of the R1 substituent were decisive for PET-inhibiting activity. The most potent PET inhibitor was (5Z)-5-(4-bromobenzylidene)-2-thioxo-1,3-thiazolidin-4-one (IC50 = 3.0 μmol/L) and the highest antialgal activity was exhibited by (5Z)-5-(4-chlorobenzylidene)-2-thioxo-1,3-thiazolidin-4-one (IC50 = 1.3 μmol/L).
