A Dicopper(II)-Based Carbonic Anhydrase Model-Quantum-Chemical Evaluation of the Mechanistic Pathway.

The cyanobacterium Prochloron didemni, an obligate symbiont of different species of colonial ascidians, occurring in the Pacific and Indian Oceans, produces a variety of cyclic peptides. These patellamide-type macrocycles lead to relatively stable dicopper(II) complexes that are extremely efficient carbonic anhydrase mimics, the most active model systems known so far. Importantly, it recently was shown that copper(II) is coordinated to patellamide derivatives in Prochloron cells.

Identification of a novel drug molecule for neurodegenerative disease from marine algae through analysis.

Cognitive functions are lost due to the rapid hydrolysis of acetylcholine including Acetylcholinesterase (AChE) and Butyrylcholinesterase (BChE).
