A sensitive liquid chromatography-tandem mass spectrometry method for quantitative determination of dasotraline in human plasma and its clinical application.
Skende E, Zheng N, Chen YL. Skende E, et al. J Pharm Biomed Anal. 2020 Nov 30;191:113611. doi: 10.1016/j.jpba.2020.113611. Epub 2020 Sep 8. J Pharm Biomed Anal. 2020. PMID: 33007733
Dasotraline and the internal standard (IS) d(4)-(13)C(4)-dasotraline were extracted from the 0.500-mL plasma pre-mixed with 0.20-mL of 0.5 M sodium bicarbonate solution by a 3-mL of hexane containing 0.7 % sec-butyl alcohol. The organic extract, after dried down, wa …

Activation of carboxylic acids by pyrocarbonates. Synthesis of arylamides of N-protected amino acids and small peptides using dialkyl pyrocarbonates as condensing reagents.
Pozdnev VF. Pozdnev VF. Int J Pept Protein Res. 1994 Jul;44(1):36-48. doi: 10.1111/j.1399-3011.1994.tb00402.x. Int J Pept Protein Res. 1994. PMID: 7960403
Activation of carboxylic acids was achieved via dialkyl pyrocarbonates (ROCO)2O, (R = ethyl, isopropyl, sec-butyl, tert-butyl) in aprotic solvents in the presence of tertiary amines. A convenient one-pot procedure for the preparation of arylamides from N-protected a …

[Stability of esters in the blood in vitro].
Ghittori S, Imbriani M, Borlini F, Pezzagno G, Zadra P. Ghittori S, et al. Boll Soc Ital Biol Sper. 1984 Nov 30;60(11):2207-13. Boll Soc Ital Biol Sper. 1984. PMID: 6525281 Italian.
During our experiments we found that most acetates we tested (n-butyl-acetate; sec.butyl-acetate; ter-butyl-acetate; ethyl-acetate; amyl-acetate; methyl-acetate; n-propyl-acetate) were particularly unstable and hydrolyzed rapidly in alcohol and in the corresponding …
