Cypermethrin (CP) is widely used for controlling agricultural and indoor vermin. Previous studies have reported the stereoselective difference of CP in biological activities. However, little is known about their potential mechanisms between metabolic phenotypes and endocrine‐disrupting effects. Herein, nuclear magnetic resonance (NMR)‐based metabolomics combining metabolite identification and pathway

Enantioselective LC-MS/MS method for the determination of cloperastine enantiomers in rat plasma and its pharmacokinetic application. Chirality (IF 2.171) Pub Date : 2020-06-22 Jia Lun,Pengfei Zhao,Zhen Jiang,Yongbo Song,Xingjie Guo
Cloperastine is a central antitussive used to reduce the frequency and intensity of coughing on a short‐term basis. In this study, a reliable chiral LC‐MS/MS technology has been developed for the quantification of cloperastine enantiomers in the rat plasma. Carbinoxamine was selected as the internal standard. The enantioseparation of cloperastine was performed on a Chiralpak IA column with a mobile

Racemic ethyl 2,3‐dibromopropionate, commercially available at low price, is a key intermediate used in the synthesis of several heterocycle fragments, which are present in many biologically active compounds. Surprisingly, the enantiomers are not commercially available and have never been described in the literature. In this work, we undertook two different strategies to obtain these enantiomers, which

Synchronous bond molecular dynamics of conjugated chlorocyclopropyl alk-yn-enes revealed by ECD and UV-vis. Chirality (IF 2.171) Pub Date : 2020-06-21 Colin K Skepper,Tadeusz F Molinski
Chlorocyclopropanes (CCPs) conjugated to alk‐yn‐enes occur in a unique family of polyketide natural products from marine sponges. Synthesis of several optically enriched analogs of CCPs and measurement of their UV–vis spectra and electronic circular dichroism (ECD) spectra reveal unusually strong hyperconjugation that constrains and aligns the cyclopropyl C‐C bond with the π‐plane of the distal ene‐bond

Enantioseparation of citalopram enantiomers by capillary electrophoresis: Method development through experimental design and computational modeling. Chirality (IF 2.171) Pub Date : 2020-06-07 Monica Budău,Gabriel Hancu,Daniela Lucia Muntean,Lajos Attila Papp,Anca Gabriela Cârje,Vladimir Garaj
Citalopram (CIT) is a frequently used modern antidepressant that inhibits selectively serotonin reuptake in the brain. It has a chiral center in its structure and is used in therapy as both racemic mixture and pure enantiomer as its pharmacological effect is almost entirely associated with S‐CIT. The aim of this study was the development of a simple and rapid capillary electrophoresis (CE) method for
