Spectrophotometric method for determination of cu(II) in the trace quantities was developed by using piperazine dithiocarbamate as ligand in ammonium chloride-ammonium hydroxide medium at pH -9.5. The procedure developed was applied for the estimation of cu(II) in microgram quantities in the water samples and the method developed was found to be simple and sensitive. Spectrophotometry is one of...

The first elemental cluster with hexacapped trigonal bipyramidal geometry is revealed in the luminescent undecanuclear silver complex which is stabilized by nine dithiocarbamate ligands and has an interstitial hydride. The hydride position within the Ag(11) cage is confirmed by a DFT investigation.

Aging is associated with NF-κB-dependent pro-inflammation. Here we demonstrated that inhibition of NF-κB with pyrrolidine dithiocarbamate increases the median lifespan (13-20%) and the age of 90% mortality (11-14%) in Drosophila melanogaster females and males, respectively.

Starting with metal dithiocarbamate complexes, we synthesize colloidal Cu(2)ZnSnS(4) (CZTS) nanocrystals with diameters ranging from 2 to 7 nm. Structural and Raman scattering data confirm that CZTS is obtained rather than other possible material phases. The optical absorption spectra of nanocrystals with diameters less than 3 nm show a shift to higher energy due to quantum confinement.

Thermogravimetric (TG) studies have been carried out for some bimetallic dithiocarbamate complexes o f the type ZnML4 and NiM 'L4 [M = Co(II), Cu(II); M' = Zn(II), Hg(II); L = N-methylcyclohexyldithiocarbamate; L' = N-ethylcyclohexyldithiocarbamate]. From TG curves, the order, apparent activation energy and apparent activation entropy for the thermal decomposition reaction have been calculated....

Chemotherapy and radiotherapy are often used to treat Acute Lymphoblastic Leukemia (ALL). However, the resistance problem of treatment using current drug in ALL patients has decreased effectiveness such therapy. Therefore, a study needs be conducted identify potential new anticancer agents. Organotin (IV) dithiocarbamate, an organometallic compound, causes toxic effects on cancer cells vitro vi...

BACKGROUND AND PURPOSE Human brain arteriovenous malformation tissue displays increased levels of vascular endothelial growth factor (VEGF) as well as matrix metalloproteinase (MMP)-9, a tissue protease associated with various intracerebral hemorrhage (ICH). We hypothesized that increased MMP-9 was associated with ICH induced by vascular endothelial growth factor hyperstimulation and that this ...
