1,4,7‐triazacyclononane‐based bifunctional picolinate ligands for efficient copper complexation
(Wiley, 2017-05-10)[Abstract] Three 1,4,7‐triazacyclononane‐based (tacn‐based) ligands containing picolyl and picolinate pendant arms (no3py, no2pa1py, and no3pa) were synthesized, and their copper(II) complexation properties were studied ... -
Disorders provoked by copper in the marine diatom Phaeodactylum tricornutum in short-time exposure asays
(Station Biologique de Roscoff, 1997)[Abstract] Copper toxicity on the marine diatom Phaeodactylwn tricomutum was assessed after 24.liours of exposure, using different parameters: growth, 14C-bicarbonate assimilation, 3H-thymidine incorporation, photosynthetic ... -
Highly stable complexes of divalent metal ions (Mg2+, Ca2+, Cu2+, Zn2+, Cd2+, and Pb2+) with a dota‐like ligand containing a picolinate pendant
(Wiley, 2014-12)[Abstract] The stability constants of complexes of the macrocyclic ligand do3a‐pic4– (H4do3a‐pic = 2,2′,2″‐{10‐[(6‐carboxypyridin‐2‐yl)methyl]‐1,4,7,10‐tetraazacyclododecane 1,4,7‐triyl}triacetic acid) with several divalent ... -
On the Dissociation Pathways of Copper Complexes Relevant as Pet Imaging Agents
(Elsevier, 2022)[Abstract] Several bifunctional chelators have been synthesized in the last years for the development of new 64Cu-based PET agents for in vivo imaging. When designing a metal-based PET probe, it is important to achieve ... -
Potential use of flow cytometry in toxicity studies with microalgae
(2000-03)[Abstract]Cytotoxic effects of aquatic pollutants on microalgae are very heterogeneous, and they are influenced by environmental conditions and the test species. Stress produced by copper or paraquat addition to the culture ... -
Response of the marine microalga Dunaliella tertiolecta (Chlorophyceae) to copper toxicity in short time experiments
(Springer, 1995-02)Heavy metals are introduced into aquatic ecosystems from industrial wastes, agricultural runoff and mining activities. The toxicity of heavy metal ions in solution to microalgae is well known. The essentiality and toxicity ...
