A solution of diisopropylamine (29.2 mL, 0.21 mol) in dry tetrahydrofuran (186 mL) and 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone (62 mL) was cooled to -78 C. and then treated with a 2.5M solution of n-butyllithium in hexanes (83.4 mL, 0.21 mol). The yellow-orange reaction mixture was stirred at -78 C. for 35 min and then slowly treated with a solution of 4-(methanesulfonyl)phenyl acetic acid methyl ester (45.35 g, 0.20 mol) in dry tetrahydrofuran (186 mL) and 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone (62 mL). The reaction mixture turned dark in color. The reaction mixture was then stirred at -78 C. for 50 min, at which time, a solution of iodomethylcyclopentane (50.08 g, 0.24 mol) in a small amount of dry tetrahydrofuran was added slowly. The reaction mixture was then stirred at -78 C. for 50 min, and then allowed to warm to 25 C., where it was stirred for 36 h. The reaction mixture was quenched with water (100 mL), and the resulting reaction mixture was concentrated in vacuo to remove tetrahydrofuran. The remaining residue was diluted with ethyl acetate (1.5 L). The organic phase was washed with a saturated aqueous sodium chloride solution (1*500 mL), dried over sodium sulfate, filtered, and concentrated in vacuo. Flash chromatography (Merck Silica gel 60, 70-230 mesh, 3/1 hexanes/ethyl acetate) afforded 3-cyclopentyl-2-(4-methanesulfonylphenyl)propionic acid methyl ester (41.79 g, 68%) as a yellow viscous oil: EI-HRMS m/e calcd for C16H22O4S (M+) 310.1239, found 310.1230.

DFT, SERS-concentration and solvent dependent and docking studies of a bioactive benzenesulfonamide derivative

Spectroscopic analysis, DFT studies and surface enhanced Raman scattering (SERS) of antimicrobial bioac- tive 4-[(5-tert-butyl)2-hydroxybenzylidene]amino-N-(4,6-dimethylpyrimidin-2-yl)benzenesulfonamide (THPB) have been studied on different silver sols. Intensity and hence enhancement variations are observed for Raman and SERS bands. Observed changes in the ring modes may be due to surface pi-electron interactions and presence of this indicated that molecule is inclined with respect to the metal surface. Changes in orientation are seen in SERS spectra depending on concentration. The molecular docking results show that binding affinity and interactions with the receptors may be supporting evidence for further studies in design further THPB pharmaceutical applications. Reactivity properties are obtained from DFT analysis. (C) 2020 Elsevier B.V. All rights reserved.

Case Report: Rapid Treatment of Uridine-Responsive Epileptic Encephalopathy Caused by CAD Deficiency

We present two unrelated Chinese patients with CAD deficiency manifesting with a triad of infantile-onset psychomotor developmental delay with regression, drug-refractory epilepsy, and anaemia with anisopoikilocytosis. Timely translation into uridine supplementation, within 2-months of disease onset, allowed us to stop conventional anti-epileptic drugs and led to dramatic improvement in the clinical symptoms, with prompt cessation of seizures, resolution of anaemia, developmental progress, and prevention of development of severe and non-reversible manifestations. The remarkable recovery and prevention of advanced disease with prompt treatment, highlights the need to act immediately upon genetic diagnosis of a treatable disease. This further reinforces CAD deficiency as a treatable neurometabolic disorder and emphasises the need for a biomarker or genetic new born screening for early identification.
