Because of its polymerisation tendency, it is not suitable for therapeutic use. 1,4-reduction of the conjugated diene gives dihydrostreptazolin which is stable, but has very limited antimicrobial properties.[1]

The first total synthesis of (racemic) streptazolin was achieved in 1985 with the aid of a modified Ferrier rearrangement.[3][4]
