Abstract This review updates the field of enantioselective indium-catalyzed transformations all types since 2012. It shows that asymmetric indium catalysis, suits growing demand for greener processes, offers a real opportunity to replace toxic metals in near future. 1 Introduction 2 Allylations, Propargylations, and Allenylations Carbonyl Compounds Derivatives 2.1 Allylations 2.2 Propargylation...

Of the known elements, nearly 80% are either metals or metalloids. The highly reactive nature of most metals result in their forming complexes with other compounds such oxygen, sulfide and chloride. Although this reactivity is the primary means by which they are toxic, many metals, in trace amounts, are vital to normal physiological processes; examples include iron in oxygen transport, manganes...

The application of nanotechnology in the corrosion protection of metals has recently gained momentum; Environmental impact can improved by utilizing nanostructure particulates in corrosion inhibition, Nano composites have also proven to be an effective alternative to other hazardous and toxic compounds, the present article reports some of the preliminary investigations on the corrosion-resistan...

19-Substituted geldanamycin derivatives are efficient Hsp90 inhibitors, without the toxicity associated with the other benzoquinone ansamycins, thus giving them potential for use as molecular therapeutics in cancer and neurodegeneration. Here a new method of synthesising these important compounds is reported, eliminating the need for toxic metals and metalloids.

We report here the genome sequence of Labrenzia sp. EL143, an alphaproteobacterium isolated from the gorgonian coral Eunicella labiata that possesses various genes involved in halogen and aromatic compound degradation, as well as polyketide synthesis. The strain also maintains multiple genes that confer resistance to toxic compounds such as heavy metals and antibiotics.

Acidophilic, heterotrophic bacteria isolated from acidic mine effluent metabolised a range of aliphatic compounds. Aliphatic acids, which are normally thought to be toxic to acidophiles, were utilised as substrates for energy and growth by these bacteria. This biodegradative ability, concomitant with their tolerance of heavy metals, has demonstrated the potential for using these organisms for t...

The heavy metals chiefly include Pb, Hg, Cd, Cr, Cu, Zn, Mn, Ni, Ag, etc. The heavy metals, viz., As, Cd, Pb and Hg are considered most toxic to humans, animals, fishes and environment. Excessive concentrations of heavy metals are detrimental. They destabilize ecosystems because of their bioaccumulation in organisms, and toxic effects on biota and even death in most living beings. All heavy met...

Although chemical agents were not employed as offensive weapons during the past war, nevertheless it was imperative to pursue vigorously investigations on the treatment of chemical warfare casualties. Inasmuch as a number of chemical warfare agents contain arsenic, attention was focused on the synthesis of compounds capable of antagonizing the local and systemic effects of arsenical vesicants. ...
