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. 4897-84-1, formula is C5H9BrO2, Name is Methyl 4-bromobutanoate, Name: Methyl 4-bromobutanoate
Ning, Xiangxue;Tan, Guiyu;Chen, Xiaojiao;Wang, Mian;Wang, Baomin;Cui, Liwang research published 《 Development of a lateral flow dipstick for simultaneous and semi-quantitative analysis of dihydroartemisinin and piperaquine in an artemisinin combination therapy》, the research content is summarized as follows. Dihydroartemisinin (DHA) and piperaquine (PPQ) are two drugs used in an artemisinin-based combination therapy (ACT). The circulation of counterfeit antimalarial drugs demands the development of simple, point-of-care (POC) tests for monitoring drug quality. Here we aimed to design an antibody-based lateral flow dipstick assay for simultaneous quality control of DHA and PPQ. To obtain a monoclonal antibody (mAb) for PPQ, one structural unit of the sym. PPQ mol. was used to derive a carboxylic acid for linkage to a carrier protein as immunogen. Screening of hybridoma cells identified an mAb 4D112B2 that reacted with the PPQ-based immunogen. A highly-sensitive icELISA was designed based on this mAb, which showed 50% inhibition concentration of PPQ at 1.66 ng/mL and a working range of 0.35 – 7.40 ng/mL. The mAb showed 10.2, 15.9 and 30.4% cross reactivity to hydroxychloroquine sulfate, chloroquine and amodiaquine, resp. No cross reactivity was observed to lumefantrine, mefloquine artemisinin and its derivatives Using our previous DHA dipstick design, a lateral flow dipstick for simultaneous anal. of PPQ and DHA was developed. The indicator ranges for PPQ and DHA were 2 – 5μg/mL and 250 – 500 ng/mL, resp. The dipstick was used to semi-quant. analyze PPQ and DHA content in com. ACT drugs, which produced agreeable results to those determined by high-performance liquid chromatog. This combination dipstick makes it a potential POC device for quality control of the two active ingredients in a commonly used ACT.
Name: Methyl 4-bromobutanoate, Methyl 4-bromobutyrate,also as known as 4-Bromobutyric acid methyl ester, is a useful research compound. Its molecular formula is C5H9BrO2 and its molecular weight is 181.03 g/mol. The purity is usually 95%.
4-Bromobutyric acid methyl ester is a synthetic compound that can be used to inhibit the activity of the G1 phase cyclin-dependent kinases. It has been shown to inhibit protein synthesis by alkylating the amino groups of proteins and fatty acids. 4-Bromobutyric acid methyl ester also inhibits the growth of cancer cell lines, such as renal carcinoma cells. The mechanism of action for this drug is not well understood, but it may be due to its ability to bind with monoclonal antibodies and enter kidney cells by passive diffusion., 4897-84-1.
