Thiophene bioisosteres
WebIn summary, we investigated whether a thiophene ring can become a bioisostere for a benzene ring for fungicidal activity against plant pathogens in vivo and in vitro. We also evaluated the inhibitory activity at the action site. Two of the thiophene regioisomers could act as bioisosteres for the benzene ring, whereas one isomer could not.
