Summary
1. A direct comparison of albonoursin with “component 2” isolated from the producing agent of phalamysin (a mutant ofActinomyces noursei) has established their identity.
2. Phenylpyruvic acid and acetone have been identified as products of the acid decomposition of albonoursin.
3. The presence of the following groupings in the albonoursin molecule has been shown: C6H5-CH=C-C, (CH3)2 CH-C= or (CH3)2C=C, two amide groups, and two hydrogen atoms readily capable of being replaced by halogen atoms (under the action of Br2 or SOCl2).
4. There is no malonamide group in albonoursin.
