Benzastatins A, B, C, and D: new free radical scavengers from Streptomyces nitrosporeus 30643. II. Structural determination.
The structures of benzastatins A, B, C, and D, new free radical scavengers, were determined by spectroscopic studies. Benzastatins A and B incorporate the para-aminobenzamide unit which is rare in fungal metabolites. Benzastatins C and D are unique alkaloids related to virantmycin; they contain the tetrahydroquinoline unit in the molecules.
