Calpains are involved in a variety of calcium-regulated cellular processes, such as signal transduction, cell proliferation, differentiation, and apoptosis. Excessive calpain activation contributes to serious cellular damage and has been reported in many pathological conditions. 4-Quinolinone 2-carboxamide derivatives were prepared

The cyanobacterium Microcystis aeruginosa is widely known for its production of the potent hepatotoxin microcystin. This cyclic heptapeptide is synthesized non-ribosomally by the thio-template function of a large modular enzyme complex encoded within the 55-kb microcystin synthetase gene (mcy) cluster.
