Abstract

The auxins, plant hormones, regulate many aspects of the growth and development of plants. Terfestatin A (TrfA), a novel auxin signaling inhibitor, was identified in a screen of Streptomyces sp. F40 extracts for inhibition of the expression of an auxin-inducible gene. However, the mode of action of TrfA has not been elucidated. To identify the active core structure, 25 derivatives of TrfA were synthesized and their inhibitory activities against ...
