Calcimycin (A-23187) hemicalcium salt is an antibiotic and a unique divalent cation ionophore (like calcium and magnesium). Calcimycin hemicalcium salt induces Ca²⁺-dependent cell death by increasing intracellular calcium concentration. Calcimycin hemicalcium salt inhibits the growth of Gram-positive bacteria and some fungi. Calcimycin hemicalcium salt also inhibits the activity of ATPase and uncouples oxidative phosphorylation (OXPHOS) of mammalian cells. Calcimycin hemicalcium salt induces apoptosis and autophagy.

AcrAP1 (AP1-Z1) is an antimicrobial peptide found in the venom of the Arabian scorpion (Androctonus crassicauda). AcrAP1 has antimicrobial activity and can inhibit the growth of Gram-positive and Gram-negative bacteria as well as yeast. AcrAP1 exerts antitumor activity by promoting apoptosis of cancer cells and inhibiting angiogenesis. AcrAP1 can be used in cancer therapy research.

wkwkwNGwkwkw-NH2 is a self-assembling β-hairpin antimicrobial peptide. wkwkwNGwkwkw-NH2 self-assembles into nanofibers. wkwkwNGwkwkw-NH2 interacts with LPS on the surface of the bacterial membrane and then disrupts the bacterial outer membrane, inner membrane, and cytoplasmic membrane to exert its antibacterial effects. wkwkwNGwkwkw-NH2 has high antibacterial activity and low hemolytic activity. wkwkwNGwkwkw-NH2 significantly reduces the S. aureus ATCC 25923 load at the skin wound. wkwkwNGwkwkw-NH2 displays synergistic effects when combined with antibiotics. wkwkwNGwkwkw-NH2 facilitates wound healing.

Arphamenine B hemisulfate is a Zn²⁺-dependent exopeptidase that selectively removes arginine and/or lysine residues from the NH2-terminus of several peptide substrates. Arphamenine B hemisulfate is an inhibitor of aminopeptidase B that can be isolated from bacteria. Arphamenine B hemisulfate enhances the immune response and is used to characterize novel proteases.

S 3578 sulfate is a broad-spectrum antibacterial agent, particularly effective against methicillin-resistant Staphylococcus aureus (MRSA) (MIC = 0.78-3.13 μg/mL) and Pseudomonas aeruginosa (MIC = 1.56-6.25 μg/mL). S 3578 sulfate can be used in the research of infectious conditions.

ROS inducer 1 (compound I₂₉) is a fungicide, with EC₅₀ against Xanthomonas axonopodis pv. citri (Xac), Xanthomonas oryzae pv. oryzae (Xoo), and Pseudomonas syringae pv. actinidiae (Psa) of 5.73, 6.62 and 9.05 μg/mL. ROS inducer 1 can effectively induce the production of ROS in Xanthomonas cells and inhibit rice bacterial blight. ROS inducer 1 has the potential to study bacterial infection in crops.

Lienomycin, a polyene antibiotic produced by Actinomyces distatochromogenes var. lienomycini, exhibits antifungal, antibacterial and antitumor activity.

Aurein 5.2 is an antibiotic antimicrobial peptide.
