supporting information, p. 928 - 931 (2016/02/05)
(Methylthio) acroleins 1a-m were shown to be stable unlike their counterpart the chloroacroleins and their efficacy as 1,3-dielectrophilic properties have now been examined successfully in this work. They are shown to react with ethyl thioglycolate in the
Synthesis, cytotoxicity and effects of some 1,2,4-triazole and 1,3,4-thiadiazole derivatives on immunocompetent cells
Mavrova, Anelia Ts.,Wesselinova, Diana,Tsenov, Yordan A.,Denkova, Pavletta
experimental part, p. 63 - 69 (2009/04/07)
Novel derivatives of 4,5-substituted-1,2,4-triazole-thiones and 2,5-substituted-1,3,4-thiadiazoles were synthesized and evaluated for their cytotoxicity. The biological study indicated that compounds 4-ethyl-5-(4,5,6,7-tetrahydro-1-benzothien-2-yl)-2,4-di
