Gramicidin S (Gramicidin soviet) is a cationic cyclic peptide antibiotic that selectively targets bacterial cell membranes and has anticancer activity. Gramicidin S also exerts antibacterial activity by destroying membrane integrity and interfering with membrane protein function. Gramicidin S inserts into the phospholipid bilayer through hydrophobic amino acid residues, specifically binds to negatively charged membrane lipids and disrupts membrane structure, thereby inhibiting cell division and cell wall synthesis, and ultimately causing bacterial death. Gramicidin S also inhibits ion channels, with IC50s of 41 μM, 24 μM, and 3 μM for Na +/K +-ATPase, tobacco leaf plasma membrane Mg 2+/K +-ATPase, and rat heart plasma membrane Ca 2+-ATPase, respectively .

Siamycin I (BMY-29304), a 21-residue tricyclic peptide, is a secondary metabolite in actinomycetes. Siamycin I is a HIV fusion inhibitor with ED50s of 0.05 to 5.7 μM for acute HIV type 1 (HIV-1) and HIV-2 infections. Siamycin I inhibits the gelatinase and gelatinase biosynthesis-activating pheromone (GBAP) signaling via the FsrC-FsrA two-component regulatory system in a noncompetitive manner. Siamycin I suppresses the expression of both fsrBDC and gelE-sprE transcripts. Siamycin I, a lasso peptide, interacts with lipid II and inhibits cell wall biosynthesis. Siamycin I, an antibiotic, has the potential for enterococcal infections research .

Duocarmycin A is an antitumor antibiotic and DNA alkylating agent with broad-spectrum antibacterial activity, which can serve as a payload for synthesizing antibody-drug conjugates (ADCs). Duocarmycin A selectively binds to the AT-rich minor groove of DNA, forms covalent adducts by alkylating the adenine N3 residue, thereby disrupting DNA structure and inhibiting its replication and transcription. Duocarmycin A induces apoptosis, sub-G1 phase accumulation and chromatin condensation, reduces the levels of pro-caspase-3/9, and induces p53-independent p21 expression. Duocarmycin A is widely used in the research of various malignancies, including leukemia, sarcoma, glioblastoma, as well as multiple solid tumor models such as lung cancer, breast cancer, and colorectal cancer .

Chloramphenicol Acetyltransferase, Escherichia coli is a bacterial enzyme that detoxifies the antibiotic chloramphenicol and is responsible for chloramphenicol resistance in bacteria. Chloramphenicol Acetyltransferase, Escherichia coli covalently attaches an acetyl group from acetyl-CoA to chloramphenicol, which prevents chloramphenicol from binding to ribosomes. A histidine residue, located in the C-terminal section of Chloramphenicol Acetyltransferase, Escherichia coli, plays a central role in its catalytic mechanism.
