Some biochemical effects of 2-ethylamino-1, 3, 4-thiadiazole

Biochemical Pharmacology, 1959
Abstract It has previously been demonstrated (Kaplan et a 4 ), that the injection of large doses of nicotinamide results in a ten-fold increase in the diphosphopyridine nucleotide (DPN) content of the liver of mice. The current report shows that the nicotinamide antagonist 2-ethylamino-1,3,4-thiadiazole (EAT) does not behave as a competitive ...

Synthesis, Characterization of New1, 3, 4-thiadiazole Derivatives with Studying their Biological Activity

Research Journal of Pharmacy and Technology, 2018
In this work, thiadiazole derivatives were prepared by taking advantage of active sites in (2-amino-5-mercapto-1,3,4-thiadiazole) as base. The main hetrocyclic compounds (1,3,4-thiadiazole, oxazole) etc. 2-amino-5-mercapto-1,3,4-thiadiazole compound [1] was prepared by cyclic closure of thiosemicarbazide compound with anhydrous sodium carbonate and ...

PSEUDOTETRAHEDRAL COBALT(II)-COMPLEXES OF 2, 5-DIMETHYL-1, 3, 4-THIADIAZOLE

Journal of Coordination Chemistry, 1979
Abstract The cobalt(II) complexes of 2, 5-dimethyl-1, 3, 4-thiadiazole (DTZ) Co(DTZ)2 X2 (X=Cl, Br, I, NO3) have been prepared and investigated. Their observed magnetic moments lie in the range 4.4–4.6 B.M. The complexes have a pseudo-tetrahedral coordination; a threefold splitting of the electronic v 2 and v 3 bands of the halide complexes indicate a ...
