Penicillin is a beta-lactam antibiotic derived from Penicillium fungi. It interferes with the final stage of bacterial cell wall synthesis, the cross-linking of different peptidoglycan strands.

Streptomycin is an aminoglycoside antibiotic produced by Streptomyces. It binds to the 30S subunit of the bacterial 70S ribosome and blocks the initiation complex of protein synthesis.

Amphotericin B is a polyene antifungal agent originally extracted from Streptomyces. It interferes with the permeability of cell membranes of sensitive fungi and yeasts. Amphotericin B forms a complex with ergosterol and causes leakage of low molecular weight substances from the cells.
