Background:

FR900359 is a cyclic depsipeptide that has been found inA. crenataand is an inhibitor of Gα_q, Gα₁₁, and Gα₁₄(IC₅₀s = 13.18, 10.47, and 10 nM, respectively).^1,2It is selective for these Gα subunits over a panel of additional Gα subunits, including Gα_sand Gα_i, in bioluminescence resonance energy transfer (BRET) assays at 1 µM.³FR900359 (1 µM) induces relaxation of precontracted isolated mouse tail arteries and inhibits platelet aggregation induced by U-46619 in washed isolated human platelets cultured with aspirin in a concentration-dependent manner.^3,4It induces cell cycle arrest at the G₁phase and reduces proliferation and serum-induced migration of B16 melanoma cells.³FR900359 (2.5 µg/animal) inhibits airway hyperresponsiveness in a mouse model of house dust mite-induced allergic asthma.⁵
