Out of the blue: Ammosamides A (1) and B (2) were isolated from a marine streptomycete collected at a depth of more than 1600 m. By employing a blue‐fluorescent diaminocoumarin conjugate of 2 (see structure), myosin was identified as a cellular target of these antiproliferative natural products. The totalsynthesis of 1 and 2 has now been completed, thus allowing further elaboration of the chemical
