Convenient preparation of unsymmetrical 2,5-disubstituted 1,3,4-oxadiazoles promoted by Dess–Martin reagent
摘要:
2,5-Disubstituted 1,3,4-oxadiazoles have been conveniently prepared by oxidative cyclization of N-acyl-N'-aryliden-hydrazines promoted by all excess or Dess-Martin periodinane under Mild conditions (23 examples, up to 92% isolated yields). (C) 2009 Elsevier Ltd. All rights reserved.
Mechanistic differences between in vitro assays for hydrazone-based small molecule inhibitors of anthrax lethal factor
摘要:
A systematically generated series of hydrazones were analyzed as potential inhibitors of anthrax lethal factor. The hydrazones were screened using one UV-based and two fluorescence-based in vitro assays. The study identified several inhibitors with IC50 values in the micromolar range, and importantly, significant differences in the types of inhibition were observed with the different assays.
