Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 1117-71-1, Name is Methyl 4-bromobut-2-enoate, molecular formula is C5H7BrO2, belongs to esters-buliding-blocks compound, is a common compound. In a patnet, author is Chatzopoulou, Maria, once mentioned the new application about 1117-71-1, Recommanded Product: 1117-71-1.
Decreasing HepG2 Cytotoxicity by Lowering the Lipophilicity of Benzo[d]oxazolephosphinate Ester Utrophin Modulators
Utrophin modulation is a disease-modifying therapeutic strategy for Duchenne muscular dystrophy that would be applicable to all patient populations. To improve the suboptimal profile of ezutromid, the first-in-class clinical candidate, a second generation of utrophin modulators bearing a phosphinate ester moiety was developed. This modification significantly improved the physicochemical and ADME properties, but one of the main lead molecules was found to have dose-limiting hepatotoxicity. In this work we describe how less lipophilic analogues retained utrophin modulatory activity in a reporter gene assay, upregulated utrophin protein in dystrophic mouse muscle cells, but also had improved physicochemical and ADME properties. Notably, ClogP was found to directly correlate with pIC(50) in HepG2 cells, hence leading to a potentially safer toxicological profiles in this series. Compound 21 showed a balanced profile (H2K EC50: 4.17 mu M, solubility: 477 mu M, mouse hepatocyte T-1/2 > 240 min) and increased utrophin protein 1.6-fold in a Western blot assay.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 1117-71-1. The above is the message from the blog manager. Recommanded Product: 1117-71-1.
