• Structure elucidation using spectroscopic methods (e.g., NMR, Mass Spectrometry).

Main Results:

• Isolation of a new amide glycoside: 3-alpha-glucopyranosyloxy-N-methyl-3-phenylpropanamide (1).
• Isolation of a new cyclodipeptide: (3S,6S)-3,6-bis(4-acetamidobutyl)piperazine-2,5-dione (2).
• Complete structural determination of both compounds via spectroscopic analysis.

Conclusions:

• Two previously undescribed compounds were identified from Streptomycetes michiganensis.
• The structural diversity of microbial metabolites is further expanded by these findings.
• Spectroscopic methods are crucial for the characterization of novel natural products.
