The Leucomyosuppressin(9CI), with the CAS registry number of 106884-19-9, is also known as p-Glu-asp-val-asp-his-val-phe-leu-arg-phe-NH₂. We can get it from head extracts of the cockroach Leucophaea maderae, it can inhibit evoked transmitter release at the mealworm neuromuscular junction. This chemical's molecular formula is C₅₉H₈₄N₁₆O₁₅ and molecular weight is 1257.41. What's more, its IUPAC name is (3S)-4-[[(2S)-1-[[(2S)-1-[[1-[[(2S)-1-[[(2S)-1-[[(2R)-1-[[1-[[(2R)-1-Amino-1-oxo-3-phenylpropan-2-yl]amino]-5-(diaminomethylideneamino)-1-oxopentan-2-yl]amino]-4-methyl-1-oxopentan-2-yl]amino]-1-oxo-3-phenylpropan-2-yl]amino]-3-methyl-1-oxobutan-2-yl]amino]-3-(1H-imidazol-5-yl)-1-oxopropan-2-yl]amino]-3-carboxy-1-oxopropan-2-yl]amino]-3-methyl-1-oxobutan-2-yl]amino]-4-oxo-3-[[(2S)-5-oxopyrrolidine-2-carbonyl]amino]butanoic acid.
