Fractions from an organic extract from fresh octopus (Paraoctopus limaculatus) were studied for biological activities such as antimutagenic and antiproliferative properties using Salmonella tester strains TA98 and TA100 with metabolic activation (S9) and a cancer cell line (B-cell lymphoma), respectively. A chloroform extract obtained from octopus tentacles(More)
Purpose: To isolate and evaluate the antimutagenic properties of compounds previously identified in octopus (Paraoctopus limaculatus). Methods: Octopus fractions, previously obtained by a sequential thin layer chromatography (TLC) procedure, were subjected to further fractionation by TLC and their anti-mutagenic activity monitored using Salmonella tester(More)
In the solid state, the structure of the title compound, C(16)H(18)N(4)O(2), is stabilized by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds. These hydrogen bonds arrange the mol-ecules into a double-layer supra-molecular structure. The mol-ecular conformation is is consolidated by an intra-molecular N-H⋯N hydrogen bond. The dihedral angle between the(More)
