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

Metabolism of ο-, m-, and p-fluoro, bromo-, and iodonitrobenzenes in the rabbit was written by Bray, H. G.;James, Sybil P.;Thorpe, W. V.. And the article was included in Biochemical Journal in 1958.Application of 74440-80-5 This article mentions the following:

The metabolism of ο-, m-, and p-fluoro-, ο-, m-, and p-bromo-, and ο-, m-, and p-iodonitrobenzenes has been studied in the rabbit. The ortho and para compounds form mercapturic acids (over 30% of the dose with the fluoro and ο-bromo compounds), but the meta compounds do not. Except with p-fluoronitrobenzene (less than 10%) about 30-60% of the dose is excreted as phenols conjugated with glucuronic and sulfuric acids; except with p-bromo- and p-iodonitrobenzenes (30%) less than 10% of the dose is excreted as the corresponding anilines. The main phenolic metabolite of p-fluoronitrobenzene is p-aminophenol. ο- and m-Fluoronitrobenzenes also probably undergo hydroxyldefluorination. Apart from hydroxyldehalogenation in the fluoro compounds the metabolic fate of the fluoro-, bromo-, and iodonitrobenzenes is, in general, qualitatively similar to that of the corresponding chloro compounds (Bray, et al., C.A. 50, 17144g). Other metabolites isolated in smaller quantities were as follows: N-acetyl-S-(2-nitrophenyl)-L-cysteine, N-acetyl-S-(4-nitrophenyl)-L-cysteine, p- and m-fluoroanilines, 4-amino-2-fluorophenol, ο- and m-bromoanilines, 4-amino-3- and 4-amino-2-bromophenols, 2-amino-4-, 2-amino-5-, 2-amino-6-bromophenols, ο-, m-, and p-iodoanilines, 4-amino-3- and 2-amino-5-iodophenols. The R_f values of the various metabolites in several solvent mixtures have been determined and recorded. In the experiment, the researchers used many compounds, for example, 4-Amino-3-bromophenol (cas: 74440-80-5Application of 74440-80-5).

4-Amino-3-bromophenol (cas: 74440-80-5) belongs to organobromine compounds. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.

Reducing the Trap Density in MAPbI₃ Based Perovskite Solar Cells via Bromide Substitution was written by Pegu, Meenakshi;Ghaderian, Abolfazl;Ahmad, Shahzada;Kazim, Samrana. And the article was included in ChemPlusChem in 2022.SDS of cas: 128-08-5 This article mentions the following:

The past decade has witnessed tremendous advancement in the field of halide perovskite (PSK) as a choice of material for high-performing solar cells fabrication. Here, we investigate the impact of the halide exchange through N-bromosuccinimide (NBS) treatment in MAPbI₃ based solar cells. We observed the partial halide exchange (I^– to Br^–) or the filling of halide (X^–) vacancy upon treatment of different NBS concentrations exptl. by spectroscopic and diffractogram studies. We noted that halide exchange impacts the crystallization and is beneficial in improving the photovoltaic performance. The optimized 0.5% NBS treated PSC exhibited a power conversion efficiency of 17.87% due to an increment in open-circuit voltage (V_oc) and short circuit current (J_sc). We noted improved perovskite crystal growth upon Br^– substitution; eventually, it helps to lower the trap d., reducing non-radiative recombination and renders the enhancement of long-term stability of PSC.

Two 11-ring-fused quinacridone derivatives, TTQA (I) and DCNTTQA (II), have been synthesized by ferric chloride mediated cyclization and Knoevenagel reaction. Replacement of the carbonyl groups (in TTQA) with dicyanoethylene groups (in DCNTTQA) not only red-shifted the emission to the near-IR region but also led to a nonplanar skeleton that significantly improved the solubility of DCNTTQA. Moreover, dicyanoethylene groups rendered DCNTTQA low-lying HOMO and LUMO levels. DCNTTQA-based solution-processed field-effect transistors showed a hole mobility up to 0.217 cm² V^-1 s^-1.
