Bacitracin B3 is an antibacterial agent, which is derived from the bacterium Bacillus subtilis. Its mode of action involves the inhibition of bacterial cell wall synthesis. This is achieved by interfering with the dephosphorylation of bactoprenol, an essential carrier molecule in the transport of peptidoglycan precursors across the cytoplasmic membrane. The disruption of this process leads to a weakened cell wall, ultimately resulting in bacterial cell lysis and death.

<p>Piericidin A is a microbial metabolite, specifically a type of polyketide, which is derived from the bacterium of the genus Streptomyces. This compound acts as an electron transport chain inhibitor by specifically binding to the ubiquinone binding site of complex I (NADH:ubiquinone oxidoreductase) in mitochondria.

<p>Baumycin C2 is an anthracycline antibiotic, which is a type of chemotherapy agent used in cancer treatment. This compound is derived from the bacterium Streptomyces, known for producing specific metabolites that interfere with cellular processes. The mode of action of Baumycin C2 involves intercalating into DNA, thereby disrupting the enzyme topoisomerase II. This interference prevents proper DNA replication and transcription, ultimately leading to apoptosis in rapidly dividing cancer cells. The uses and applications of Baumycin C2 predominantly relate to its efficacy against various types of cancers, including leukemias, lymphomas, and solid tumors such as breast cancer. By targeting DNA replication, Baumycin C2 plays a crucial role in reducing tumor growth and proliferation, representing a significant tool in oncological pharmacotherapy. Researchers continue to explore its potential in combination therapies to enhance its effectiveness and mitigate resistance.</p>

<p>Tigemonam is a synthetic beta-lactam antibiotic, which is derived from chemical synthesis processes.

Bleomycin acid is a chemotherapeutic agent, which is a derivative of antibiotics isolated from the bacterium *Streptomyces verticillus*. This bioactive compound exhibits its mode of action primarily through binding to DNA and inducing strand breaks. The interaction of bleomycin acid with DNA leads to the formation of free radicals, which subsequently result in single and double-strand breaks.
