Abstract
An acetohydroxamic acid compound of formula I ##STR1## as such or in form of a complex with .beta.-cyclodextrin or hydroxypropyl-.beta.-cyclodextrin specifically inhibits 5-lipoxygenase and is useful in pharmaceutical compositions for prophylaxis and treatment of diseases due to the action of leucotrienes. The acetohydroxamic acid compound may be prepared by reacting 3-thiophenecarboxaldehyde with hydroxylamine or a salt thereof to form the corresponding oxime, reducing the oxime with a boron-containing reducing agent to form N-(thien-3-yl)methyl-hydroxylamine, and introducing an acetyl group.
