BEZ235 was dissolved in dimethylformamide. MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) cell viability assays Cell viability was determined at ~ 72 h after treatment of compounds by MTT assay as described previously.10,11 The EC50 values were calculated by CompuSyn ...
Briefly, dipeptides were synthesized in solution by coupling of the corresponding protected N- and C-terminal AAs using 2-(1H-benzotriazol-1-yl)-1,1,3-tetramethylmethyluronium hexafluoro phosphate (HBTU) in dimethylformamide as the coupling reagent. Once the reaction was finalized, protected ...
APB stock (100 mM) was freshly prepared in dimethylformamide and octamers were incubated with 10-fold excess of APB over cysteine for 3h at 25°C in the dark. After the modification, excess APB was quenched by the addition of an equimolar amount of BME, and octamers were concentrated to ...
Examples of the another organic solvent include alkylene glycol ether (acetates) such as propylene glycol monomethyl acetate and diethylene glycol monomethylether acetate; amides such as dimethylformamide and N-methylpyrrolidone; esters such as ethyl acetate, butyl acetate, and γ-butyrolactone; aliphatic...
SOLUTION: First, a spinning dope prepared by dissolving an acrylic copolymer made from acrylonitrile/vinylidene chloride/sodium 2-acrylamide-2- methylpropanesulfonate in dimethylformamide is wet-spun, drawn, and then washed with water to produce a gel-swollen fiber bundle. Subsequently, the fiber ...
The reaction step can be conducted in the presence of an organic solvent and a base. Examples of suitable organic solvents include methylene chloride, chloroform, acetonitrile, tetrahydrofuran, dimethylformamide, dimethyl sulfoxide, and mixtures thereof. The base can be, for example, pyridine, dimethyla...
