Mononuclear and binuclear copper(II) complexes of 2-benzoylpyridine-N(4)-methyl thiosemicarbazone (HL) were prepared and characterized by a variety of spectroscopic techniques. Structural evidence for the novel sulfur bridged copper(II) iodo binuclear complex is obtained by single crystal X-ray diffraction analysis. The complex [Cu2L2I2], a(More)
BACKGROUND Mutations in the MAPK (Mitogen Activated Protein Kinase) signaling pathway - EGFR/Ras/ RAF/MEK have been associated with the development of several carcinomas. ERK2, a downstream target of the MAPK pathway and a founding member of the MAPK family is activated by cellular signals emanating at the cell membrane. Activated ERK2 translocates into the(More)
BACKGROUND There have been case reports of oral squamous cell carcinoma arising from gingival overgrowth induced by phenytoin--an antiepileptic drug. However, a detailed analysis for the presence of mutations in p53 and ras genes, which are the two most frequently mutated genes in cancers, in phenytoin induced gingival overgrowth tissues has hitherto not(More)
The title compound, C(15)H(16)N(4)S, exists in the Z conformation with the thionyl S atom lying cis to the azomethine N atom. The shortening of the N-N distance [1.3697 (17) Å] is due to extensive delocalization with the pyridine ring. The hydrazine-carbothio-amide unit is almost planar, with a maximum deviation of 0.013 (2) Å for the amide N atom. The(More)
