We recently reported a new class of imidazole-based chalcones as potential antimitotic agents. In view of their promising cytotoxic activity, a comprehensive structure-activity relationship (SAR) of these compounds was undertaken focusing on four major structural variations: the length of the mol., the Michael acceptor character, the nature and substitution pattern of ring B, and the nature of the amide functionality tethering ring B. These second-generation analogs (IBCs) demonstrated a superior bioactivity profile than the previously reported imidazole chalcones (referred to as IPEs). The analog IBC-2 with one less methylene group (nor series) and para-fluoro substituted ring B demonstrated the best cytotoxicity profile among the library of compounds A computational anal. of the NCI-60 data associated both IBCs and the previously reported IPEs with the privileged pharmacol. pharmacophore of chalcones. Interestingly, biol. studies suggest that the imidazole ring is essential for cytotoxic activity of the elongated chalcone analogs. Immunofluorescence studies revealed that IBC-2, unlike IPEs, has the ability to induce microtubule catastrophe independently of Aurora-B inhibition. The effects of IBC-2 on microtubule dynamics are similar to those of Nocodazole, but the cell cycle effects appear to be different. In-silico studies demonstrate that the members of the new series have the ability to bind to the colchicine binding site of β-tubulin with binding scores similar to those of IPEs, corresponding chalcones and Nocodazole. Although tubulin binding can partially explain the biol. effects of IBC-2, on-going target identification studies are aimed at further investigation of its biol. targets. In the experiment, the researchers used many compounds, for example, 1-(1-Methyl-1H-imidazol-2-yl)ethanone (cas: 85692-37-1Quality Control of 1-(1-Methyl-1H-imidazol-2-yl)ethanone).
1-(1-Methyl-1H-imidazol-2-yl)ethanone (cas: 85692-37-1) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.Quality Control of 1-(1-Methyl-1H-imidazol-2-yl)ethanone
