In the context of drug repositioning and expanding the existing structure-activity relationship around astemizole (AST), a new series of analogs were designed, synthesized, and evaluated for their antiplasmodium activity. Among 46 analogs tested, compounds 21, 30, and 33 displayed high activities against asexual blood stage parasites (PfNF54 IC50 = 0.025-0.043μM), whereas amide compound 46 addnl. showed activity against late-stage gametocytes (stage IV/V; PfLG IC50 = 0.6 ± 0.1μM) and 860-fold higher selectivity over hERG (46, SI = 43) compared to AST. Several analogs displaying high solubility (Sol > 100μM) and low cytotoxicity in the Chinese hamster ovary (SI > 148) cell line have also been identified. In the experiment, the researchers used many compounds, for example, 1-(2-Bromoethyl)-4-methoxybenzene (cas: 14425-64-0Quality Control of 1-(2-Bromoethyl)-4-methoxybenzene).
1-(2-Bromoethyl)-4-methoxybenzene (cas: 14425-64-0) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Quality Control of 1-(2-Bromoethyl)-4-methoxybenzene
