Injectable diphenyl diselenide supplementation in dairy sheep

Revista MVZ Córdoba, 2018
Objective. The aim of this study was to evaluate the influence of subcutaneous supplementation with diphenyl diselenide ((PhSe)2) in dairy sheep infected with gastrointestinal nematodes on animal health and possible damage to environment when the feces of these animals will be used for fertilizing. Materials and methods.

Protective effects of novel organic selenium compounds against oxidative stress in the nematode Caenorhabditis elegans

Toxicology Reports, 2015
Organic selenium compounds possess numerous biological properties, including antioxidant activity. Yet, the high toxicity of some of them, such as diphenyl diselenide (DPDS), is a limiting factor in their current usage.

An isolable phosphaalumene(3) capable of small molecule activation via unique modes of reactivity

Nature Communications
The chemistry of phosphaalumenes [R–Al=P–R’] featuring multiple bonds between phosphorus and aluminum remains largely unexplored. Here we show the syntheses of a phosphaalumene(3) through either the reaction of DippNacNacM (DippNacNac = HC[(CMe)N(2,6- i ...
