METALCOMPLEXES OF TELLURIUM-CONTAINING AMINES AND AZOMETINES

Purification and in vitro antioxidant activities of tellurium-containing phycobiliproteins from tellurium-enriched Spirulina platensis

Tellurium-containing phycocyanin (Te-PC) and allophycocyanin (Te-APC), two organic tellurium (Te) species, were purified from tellurium-enriched Spirulina platensis by a fast protein liquid chromatographic method. It was found that the incorporation of Te into the peptides enhanced the antioxidant activities of both phycobiliproteins. With fractionation by ammonium sulfate precipitation and hyd...

Bacterial recovery and recycling of tellurium from tellurium-containing compounds by Pseudoalteromonas sp. EPR3.

AIMS Tellurium-based devices, such as photovoltaic (PV) modules and thermoelectric generators, are expected to play an increasing role in renewable energy technologies. Tellurium, however, is one of the scarcest elements in the earth's crust, and current production and recycling methods are inefficient and use toxic chemicals. This study demonstrates an alternative, bacterially mediated telluri...

Ultra-sensitive ROS-responsive tellurium-containing polymers.

A novel tellurium-containing polymer micelle system is reported to be responsive to 100 μM H2O2 and can undergo a series of morphological changes. The polymer micelles also respond to 2 Gy gamma radiation, which is the exact dosage a patient receives per day for clinical radiation therapy.

Tellurium and tellurium compounds

Synthesis of boron-containing primary amines.

In this study, boron-containing primary amines were synthesized for use as building blocks in the study of peptoids. In the first step, Gabriel synthesis conditions were modified to enable the construction of seven different aminomethylphenyl boronate esters in good to excellent yields. These compounds were further utilized to build peptoid analogs via an Ugi four-component reaction (Ugi-4CR) u...
