(E)-2-(4-Methylbenzylidene)hydrazinecarboxamide.

ABSTRACT: The title compound, C(9)H(11)N(3)O, was synthesized by the reaction of 4-methyl-benzaldehyde with semicarbazide. The mol-ecule adopts an E configuration about the central C=N double bond and the dihedral angle between the mean planes of the benzene ring and the carboxamide groups is 17.05 (9)°. The hydrazine N atoms are twisted slightly out of the plane of the carboxamide group [C-C-N-N torsion angle = 178.39 (14)°] and an intra-molecular N-H⋯N bond generates an S(5) ring. In the crystal, adjacent mol-ecules are connected via a pair of N-H⋯O hydrogen bonds, generating R(2) (2)(8) loops, resulting in supra-molecular [001] ribbons.

Weak C-H⋯π inter-actions link the stacks into a three-dimensional structure.

C-demethylation and 1, 2-amino shift in (E)-2-(1-(3-aminophenyl) ethylidene)hydrazinecarboxamide to (E)-2-(2-aminobenzylidene)hydrazinecarboxamide and their applications.

Project description:A Novel (E)-2-(1-(3-aminophenyl)ethylidene)hydrazinecarboxamide 1 was synthesized by traditional method and converted to (E)-2-(2-aminobenzylidene)hydrazinecarboxamide 2 by single step in DMSO at room temperature. Synthesized compound 1 was analysed by spectroscopy (NMR and LC-MS) techniques and molecule 2 was characterized using single crystal X-ray diffraction and spectroscopy (NMR and GC-MS) techniques. These analytical technique results revealed that, C-demethylation and 1, 2 amino shift in phenyl ring of compound 1 gives molecule 2. DNA binding studies of compounds 1 and 2 was carried out by electronic absorption spectroscopy. This result revealed that, compounds 1 and 2 showed hyperchromism with bathochromic shift. Anticancer activity of compounds 1 and 2 is carried out by molecular docking with five receptors.Computer aided virtual screening demonstrated that the synthesized molecules possess ideal drug likeliness, pharmacokinetics features, toxicity profile for structure based drug discovery. The molecular docking studies revealed that the synthesized molecules are significant binding with the five selected cancer receptors with minimum binding energy (kcal/mol), number of hydrogen bonds, weak interaction, docking score and cluster RMS. The docking studies also suggested that the molecules showed interactions with DNA and the theoretical values of the binding are comparable with that of the experimental values. Hirshfeld surface analysis was used to analyze and quantify the intermolecular interactions in the crystal structure of compound 2.

(E)-2-{(2-Hydroxy-naphthalen-1-yl)methyl-ene}hydrazinecarboxamide.

Project description:In the title mol-ecule, C(12)H(11)N(3)O(2), the dihedral angle between the mean planes of the naphthalene and carboxamide groups is 28.9 (8)°. The hydrazine N atoms are twisted slightly out of the plane of the carboxamide group [C-C-N-N torsion angle = -175.06 (13)°]. The crystal packing is influenced by N-H⋯O hydrogen bonding which includes a bifurcated hydrogen bond between the amide N atom and nearby carboxyl and hydroxyl O atoms. A second bifurcated hydrogen bond occurs between the hydroxyl O atom and nearby amide (inter-molecular) and hydrazine (intra-molecular) N atoms. As a result, mol-ecules are linked into a co-operative hydrogen-bonded network of infinite one-dimensional O-H⋯O-H⋯O-H chains along the (101) plane of the unit cell in a zigzag pattern, the dihedral angle between the mean planes of the naphthalene groups of adjacent mol-ecules in the chain being 86.9 (2)°. A MOPAC PM3 calculation provides support to these observations.

(2E)-2-(4-Hy-droxy-3-meth-oxy-benzyl-idene)hydrazinecarboxamide.

Project description:In the title compound, C(9)H(11)N(3)O(3), two mol-ecules are present in the asymmetric unit in which the 4-hy-droxy-3-meth-oxy-benzaldehyde and hydrazinecarboxamide units are almost planar [with r.m.s. deviations 0.0212 and 0.0066 Å, respectively, in one mol-ecule and 0.0346 and 0.0095 Å, respectively, in the other] and are oriented at dihedral angles of 9.7 (3) and 16.6 (3)°. In both mol-ecules, two S(5) ring motifs are present due to N-H⋯N and O-H⋯O hydrogen bonds. In the crystal, the mol-ecules are dimerized with each other due to pairs of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. O-H⋯O hydrogen bonds lead to the formation of a three-dimensional network.
