Curvature and Complex Analysis

This theorem is false if e ^ 0. Indeed, on the unit disc, the Kâhler metric (1 — zz)~dzdz (where n is any integer ^ 3) is complete and its curvature function K satisfies K < 0 and \K(z)\ S C(d(0, z))~. (0 = origin ofC.) The next theorem and its corollary provide information about the absence of holomorphic p-forms (p ^ 1) when the manifold is positively curved. For compact M, the result was kno...

Novel Pt(II) Complex and Its Pd(II) Aanalogue. Synthesis, Characterization, Cytotoxicity and DNA-interaction

The ability of small molecules to perturb the natural structure and dynamics of nucleic acids is intriguing and has potential applications in cancer therapeutics. This work reports the synthesis, characterization, cytotoxicity and DNA-binding studies of two cytotoxic and intercalative [M(bpy)(pyrr-dtc)]NO3 complexes (where M = Pt(II) and Pd(II), bpy = 2,2´-bipyridine and pyrr-dtc = p...

Structure and Chromotropic Properties of 2-Picolylamine-Ni(II) Complex

A symmetric complex [NiL2(H2O)2]Cl2, where L = 2-picolylamine was synthesized and characterized by spectroscopic and structural methods. Single crystal X-ray studies reveal that the Ni(II) center located in a pseudo-octahedral N4O2 environment with bidentate ligands L positioned in basal and two water molecules in the apical position. The complex is solvatochromic, ionochromic and thermochromic...

Anticonvulsant and Antimicrobial Activity of Cu (II), Zn (II) and Co (II) Complex of Isatin 3-Glycine

      The role of Cu, Zn and Co in human physiology is well documented. Isatin and glycine have inhibitory effects on central nervous system. To capitalize on these features metal complexes of isatin-3-glycine were prepared and evaluated for anticonvulsant activity. The Cu (II) complex was found to be most active among the compounds. The compounds were screened against Staphylococcus aureus...
