The structure of the title compound, C(8)H(9)N(3), a potential anti-tumour drug, was determined in order to give more insight into its structure-function relationships. The benzimidazole core of the mol-ecule was found to be exactly planar, while the substituents are displaced slightly from the mol-ecular plane [C-C-N-C and C-C-C-N torsion angles of 0.8 (3) and 179.0 (1)° for the methyl and ami...

The title compound, 3-amino-5-methyl-5-(4-pyrid-yl)imid-azol-idine-2,4-dione, C(9)H(10)N(4)O(2), was obtained by reaction of 5-methyl-5-(4-pyrid-yl)hydantoin with hydrazine. It crystallizes as a racemate in the tetra-gonal space group I4(1)/a with one mol-ecule in the asymmetric unit. The dihedral angle between the pyridine ring and the five-membered hydantoin ring is 47.99 (3)° In the crystal ...

This research aimed to produce new 1-[(aryl)(3-amino-5-oxopyrazolidin-4-ylidene) methyl]-2-oxo-1,2-dihydroquinoline-3-carboxylic acid derivatives and check their anticancer effect against the breast cancer MCF-7 cell line. The 2-oxo-1,2-dihydroquinoline-3-carboxylic (4) compound was obtained by hydrolyzing ethyl 2-oxo-1,2-dihydroquinoline-3-carboxylate (2) with thiourea anhydrous potassium carb...
