electron‐rich isonitrile is an important functionality in bioactivenaturalproducts, but its biosynthesis has been restricted to the IsnA family of isonitrile synthases. We herein provide the first structural and biochemical evidence of an alternative mechanism for isonitrile formation. ScoE, a putative non‐heme iron(II)‐dependent enzyme fromStreptomyces coeruleorubidus, was shown to catalyze the conversion

A method for eliciting an &agr;v&bgr;5 or dual &agr;v&bgr;3/&agr;v&bgr;5 antagonizing effect in a mammal which comprises administering to the mammal a therapeutically effective amount of a compound of the formula
which are useful for inhibiting restenosis, angiogenesis, atherosclerosis, diabetic retinopathy, macular degeneration, inflammation or tumor growth.
Fibrinogen receptor antagonists having the formula ##STR1## for example ##STR2## which are useful for inhibiting the binding of fibrinogen to blood platelets and for inhibiting the aggregation of blood platelets.
