Structure elucidation of two differentiation inducing factors (DIF-2 and DIF-3) from the cellular slime mould Dictyostelium discoideum

Abstract
Two endogenous differentiation-inducing factors (DIF-2 and DIF-3), which induce stalk-cell differentiation in the cellular slime mould Dictyostelium discoideum, have been identified as the pentan-1-one and monochloro analogues respectively of DIF-1 {1-[(3,5-dichloro-2,6-dihydroxy-4-methyoxy)phenyl]hexan-1-one}. These compounds represent a new chemical class of effector molecules.
