Abstract
The structures of two novel muscarinic receptor antagonists, 1 and 2, were determined by their spectral data and high-resolution mass measurements of their degradation products. Both are aliphatic long-chain compounds and contain amide and keto functionalities. The major microbial metabolite [1] contains three terminal guanidino groups and the minor compound [2] has two terminal guanidino groups.
