Description: FR900359, a non-ribosomal cyclic peptide derived from the soil bacterium Chromobacterium oxysporum, is a macrocyclic Gq protein inhibitor that inhibits melanoma cell proliferation and can be used in studies of asthma, inflammation, and cancer. Target: Apoptosis, ERK. Smiles:...

FR900359 is a cyclic depsipeptide that has been found in A. crenata and is an inhibitor of Galphaq, Galpha11, and Galpha14 (IC50s = 13.18, 10.47, and 10 nM, respectively). It is selective for these Galpha subunits over a panel of additional Galpha subunits, including Galphas and Galphai, in bioluminescence resonance...
