Schematic diagram of protection mechanism of metalloporphyrins in Cisplatin induced kidney injury.

, 2014
Metalloporphyrins induce HO-1 resulting in antioxidant defense and autophagy during cisplatin induced kidney injury. Metalloporphyrins also neutralize superoxide or scavenge peroxynitrite generated during cisplatin exposure. All combitorial effects leads

Supramolecular systems and their connection with metal–organic structures

Frontiers in Chemistry
Supramolecular structures with specific applications are a pillar in several areas of science. Thus, from a contemporary point of view, there are several reasons to embrace a systematic order of the supramolecular concept itself.

Studies of Metalloporphyrins and Tantalum Amide Imide Compounds [PDF]

, 2015
The focus of this dissertation is on two different subjects. The first examines the magnetic and structural properties of metalloporphyrins. In these studies, neutrons were used to probe the magnetic properties of metalloporphyrins.

Probing The Mechanism Of Insulin Aggregation With Added Metalloporphyrins

, 2008
The mechanism of inhibition of insulin-based amyloid gel formation by metal derivatives of tetrakis(4-sulfonatophenyl)porphyrin has been investigated. Time-course UV/vis measurements in conjunction with atomic force microscopy (AFM) were used to study ...

Synthesis, spectroscopic characterization and thermogravimetric analysis of two series of substituted (metallo)tetraphenylporphyrins

Beilstein Journal of Nanotechnology, 2017
Subsequent treatment of H2TPP(CO2H)4 (tetra(p-carboxylic acid phenyl)porphyrin, 1) with an excess of oxalyl chloride and HNR2 afforded H2TPP(C(O)NR2)4 (R = Me, 2; iPr, 3) with yields exceeding 80%.

Preparation, Structure and Spectra of\ud \ud Meso-metalloporphyrins [PDF]

, 2005
This thesis describes the synthesis and characterisation of new examples of meso-n1-organometallic porphyrins. These porphyrins were originally encountered as catalytic intermediates in the C-C bond forming reaction on the porphyrin periphery using ...

Femtosecond electronic relaxation of excited metalloporphyrins in the gas phase

, 2006
A systematic study of the ultrafast decay of metalloporphyrins containing various transition metals with partially filled 3d shells and zinc 3d filled is reported here after excitation in the second excited state of the system Soret band.

Work Function Studies of Metalloporphyrins Interacting with Volatile Compounds

, 1997
It is known that metalloporphyrins exhibit good chemical sensing properties. The variation of several features and parameters (such as optical spectra, mass, conductivity) are currently exploited to obtain chemical sensors. In this paper an investigation
