Penipurdin A (Compound 1), an anthraquinone, is a microbial secondary metabolite. Penipurdin A can be isolated from the soil fungus Penicillium purpurogenum SC0070. Penipurdin A has no significant cytotoxicity against cancer cells, such as A549, HepG2 and Hela cells. Penipurdin A has antibacterial activity against Enterococcus faecalis and Staphylococcus aureus.

Citreamicin alpha (LL-E 19085-alpha) is an antibiotic whose in vitro antimicrobial activity against 429 clinical isolates of Gram-positive cocci has been tested by the agar dilution method. These microorganisms included 313 strains of Staphylococci and 116 strains of Streptococci. The in vitro activity of Citreamicin alpha was compared with that of ampicillin, amoxicillin, ceftriaxone, erythromycin, and vancomycin. For Staphylococci, the MIC values of Citreamicin alpha ranged from 0.12-4.0 μg/ml, and for Streptococcus pyogenes of the genus Streptococcus, it was 0.03-0.12 μg/ml. However, enterococci were relatively resistant, requiring 2.0 μg/ml of the agent to inhibit 64% of the 62 tested strains. The in vitro activity of this antibiotic was much better than that of ampicillin, amoxicillin, ceftriaxone, and erythromycin, but comparable or slightly inferior to that of vancomycin.

Protein kinase G inhibitor-1 (Compound 270) is a mycobacterial protein kinase G inhibitor, with an IC₅₀ of 0.9 μM. Protein kinase G inhibitor-1 can be used for mycobacterial infection research.

Antimycobacterial agent-6 (compound 25) is a potent inhibitor of Mycobacterium tuberculosis (Mtb)，targeting to both wild-type and fluoroquinolone-resistant Mtb strains. Antimycobacterial agent-6 inhibits Mtb DprE1-C387S mutant with MIC₉₀s of 0.9 μM (H37Rv)，0.9 μM (MoxR)，0.5 μM (DprE1-P116S)，respectively.

Perilla leaf extract (Folium perillae acutae extract) is an extract of the leaves of Perilla frutescens that can be used to inhibit the replication of SARS-CoV-2.

5'-O-DMT-2'-O-TBDMS-rI is a modified nucleoside. 5'-O-DMT-2'-O-TBDMS-rI can be used in the synthesis of deoxyribonucleic acid or nucleic acid.

G092 is a potent inhibitor of MsbA. MsbA is an ABC transporter. Transmembrane ATP-binding cassette (ABC) transporters are crucial cellular machines that move molecules small and large across membranes. G092 has the potential for the research of antimicrobial agents.

Remdesivir maleate (GS-5734 maleate) is a nucleoside analogue with effective antiviral activity. Remdesivir maleate can inhibit the synthesis of viral DNA or RNA. Remdesivir maleate can be used for the research of infection, such as SARS-CoV and MHV infection.

KN-17 is a modified based on the structure of cecropin B (HY-P0092), can effectively interfere with bacterial growth and induce the migration of human bone marrow stromal cells (hBMSCs). KN-17 can significantly stimulate angiogenesis in vitro and in vivo.

Imiquimod-d₉ is deuterium labeled Imiquimod. Imiquimod (R 837), an immune response modifier, is a selective toll like receptor 7 (TLR7) agonist. Imiquimod exhibits antiviral and antitumor effects in vivo. Imiquimod can be used for the research of external genital, perianal warts, cancer and COVID-19.

HCV Peptide (257-266) is a peptide. HCV Peptide (257-266) can be used for the research of hepatitis C virus (HCV) .

UCI-1 is a SARS-CoV-2 main protease (M^pro) cyclic peptide inhibitor with an IC₅₀ of 160 μM. UCI-1 shows no obvious cytotoxicity at the concentration of inhibiting M^pro. UCI-1 can be used in the study of anti-COVID-19 drugs.

FtsZ-IN-9 (compound 11) is an antimicrobial agent. FtsZ-IN-9 inhibits the assembly of Mycobacterium smegmatis FtsZ (MsFtsZ)_[1].

Maximin 2 is an antimicrobial peptide derived from skin secretions of Bombina maxima. Maximin 2 has cytotoxicity on tumor cells and spermicidal effect.

IP6C is a specific inhibitor and phage sensitizer targeting type II Thoeris systems. IP6C competitively binds to histidine in the catalytic pocket of ThsB, blocks the production of the His-ADPR alarm signal and inhibits ThsA activation, thereby relieving bacterial stasis of phage replication. IP6C selectively resensitizes drug-resistant bacteria carrying type II Thoeris systems (such as Pseudomonas aeruginosa) to phage lysis, without affecting other bacteria, and shows no toxicity to mice and human cell lines. IP6C significantly improves the survival rate of infected mice, and can be used to overcome bacterial phage defense mechanisms and study Pseudomonas aeruginosa infections.
Thoeris system: (named after the Egyptian goddess of fertility and protection), is a widespread anti-phage immune defense system in bacteria and archaea. Thoeris system belongs to the "Abortion Infection (Abi)" mechanism of bacteria: when an individual bacterium detects phage invasion, it initiates a suicide program and dies, thereby blocking phage replication and spread, and protecting the surrounding bacterial population from infection.
