Synthesis, in vitro anticancer screening and radiosensitizing evaluation of some new 4-[3-(substituted)thioureido]-N-(quinoxalin-2-yl)-benzenesulfonamide derivatives Sulfonamides and quinoxaline derivatives possess many types of biological activities and have been recently reported to show substantial antitumor activity. This paper reports the synthesis of novel thioureido sulfaquinoxaline derivatives. All the newly synthesized compounds were evaluated for their in vitro anticancer activity against a human liver cell line (HEPG2) and showed higher activity than the reference drug doxorubicin.

In the title compound, C14H10F3N3O3S, there are significant twists in the molecule, as seen in the values of the dihedral angles between the pyrazole ring and each of the furan [31.1 (2)°] and benzene rings [55.58 (10)°]. The amino N atom occupies a position almost normal to the benzene ring [N—S—Car—Car(ar = aromatic) torsion angle = 83.70 (19)°]. One amino H atom forms a hydrogen bond to the tricoordinate pyrazole N atom and the other interacts with a sulfonamide O atom, forming a supramolecular chain along [010]. The chains are consolidated into a supramolecular layersviaC—H...O interaction

The asymmetric unit of the title compound, [CdCl2(C7H10N2O2S)2], contains two complex molecules with similar configurations. The CdII atoms are each six-coordinated by two thiazole N and two carbonyl O atoms from the 2-(2-amino-1,3-thiazol-4-yl)acetate ligand, and by two Cl− anions in a distorted octahedral geometry. In the crystal, intra- and intermolecular N—H...Cl hydrogen bonds create parallel chains along [1-10]. C—H...Cl interactions also occur.
