Fenpropimorph is a fungicide that inhibits the sterol pathway. Fenpropimorph inhibits δ8-δ7-sterol isomerase in yeast at low concentrations, with δ14-sterol reductase being blocked at higher levels, preventing the biosynthesis of ergosterol. Fenpropimorph also inhibits sterol synthesis in certain plants and mammalian cells.

Bromfenac sodium is a potent and orally active inhibitor of COX, with IC₅₀s of 5.56 and 7.45 nM for COX-1 and COX-2, respectively. Bromfenac sodium can be used in ocular inflammation research.

Agaric acid (Agaricinic Acid) is an orally active inhibitor of adenine nucleotide translocase found in specific fungi. Agaric acid can inhibit the biofilm formation of various bacteria such as Salmonella. Agaric acid can also induce mitochondrial permeability transition, prompting mitochondria to release Ca²⁺, disrupting the transmembrane potential, and causing mitochondrial swelling. In addition, Agaric acid can also inhibit citrate transport in liver mitochondria and participate in the inhibition of fatty acid synthesis, affecting multiple metabolic processes.

Curcumin-d₆ (Diferuloylmethane-d₆ ) is deuterium labeled Curcumin (HY-N0005). Curcumin (Diferuloylmethane), a natural phenolic compound, is a p300/CREB-binding protein-specific inhibitor of acetyltransferase, represses the acetylation of histone/nonhistone proteins and histone acetyltransferase-dependent chromatin transcription. Curcumin is a photosensitizer against microorganisms. Curcumin shows inhibitory effects on NF-κB and MAPKs, and has diverse pharmacologic effects including anti-inflammatory, antioxidant, antiproliferative and antiangiogenic activities. Curcumin induces stabilization of Nrf2 protein through Keap1 cysteine modification.

Ascaridole is an anthelmintic and also has antimalarial activity.

Gremubamab (MEDI3902) is a humanized IgG1 kappa anti-PcrV/Psl monoclonal antibody. Gremubamab binds to the PA PcrV protein and Psl exopolysaccharide. Gremubamab has the potential for the research of pseudomonas aeruginosa infections.

TAT-amide is a cell penetrating peptide. Cell-penetrating peptides (CPPs) are short amino acid sequences able to enter different cells.

Resorantel is an anthelmintic. Resorantel is used in the research of paramphistomiasis in cattle and sheep and has also been used for the research of G. aegypticus.

AA3-DLin is a biodegradable ionizable cationic lipid (pK_a = 5.8). AA3-DLin is used to combine mRNA with lipid nanoparticles (LNPs) for delivery, thereby achieving endosomal escape and cytoplasmic release. AA3-DLin can be used in research on type 2 diabetes, steroid-resistant asthma, lung cancer, ischemic stroke, breast cancer, melanoma, and COVID-19.

Brevianamide F (Cyclo(L-Pro-L-Trp)) is a mycotoxin isolated from Colletotrichum gloeosporioides, with antibacterial activity. Brevianamide F shows potent PI3Kα inhibitory activity with an IC₅₀ of 4.8 μM.

Human β-defensin-1 (HβD-1) is a cysteine-rich cationic skin-antimicrobial peptide (SAP) produced by all epithelial surfaces, but also by circulatory cells and cells of the reproductive tract. Human β-defensin-1 has antimicrobial activities against a broad-sperm bacteria.

Fusion Inhibitory Peptide (Z-D-Phe-Phe-Gly-OH, FIP, Virus Replication Inhibitory Peptide) is a potent inhibitor of the virus replication, by inhibiting the membrane fusing activity of a viral glycoprotein.

4-Hydroxybenzoic acid-d₄ is the deuterium labeled 4-Hydroxybenzoic acid. 4-Hydroxybenzoic acid, a phenolic derivative of benzoic acid, could inhibit most gram-positive and some gram-negative bacteria, with an IC50 of 160 μg/mL.

Telavancin hydrochloride (TD-6424 hydrochloride) is a bactericidal agent that exhibits inhibitory activity against Staphylococcus aureus. Telavancin hydrochloride inhibits bacterial cell wall synthesis by binding to the lipid-linked N-acetylglucosamine-N-muramyl pentapeptide (with a D-Ala-D-Ala terminus), a peptidoglycan precursor, and blocks the transglycosylation and transpeptidation steps. Telavancin hydrochloride disrupts bacterial membrane barrier function, induces dissipation of bacterial membrane potential, and causes leakage of cytoplasmic ATP and potassium ions, with its activity restricted exclusively to bacterial membranes. Telavancin hydrochloride can be used in research on bacterial infections, central venous catheter-related bloodstream infections, and Gram-positive bacterial pneumonia.

NITD-349 is an MmpL3 inhibitor that shows highly potent anti-mycobacterial activity with MIC₅₀ of 23 nM against virulent Mycobacterium tuberculosis H37Rv.

DB772 hydrate is a bovine viral diarrhoea virus (BVDV) inhibitor. DB772 also has anti-prion activity.

ddATP (2',3'-Dideoxyadenosine 5'-triphosphate) trisodium, an active metabolite of 2',3'-dideoxyinosine, is a chain-elongating inhibitor of DNA polymerase. ddATP trisodium can be used for Sanger method for DNA sequencing and research of virus infection.

Coniferin (Laricin) is a glucoside of coniferyl alcohol. Coniferin inhibits fungal melanization. Coniferin inhibits the release of certain hormones from cells, including Prostaglandin E2 and Thromboxane B2.

Eriochrome black T, Indicator is a complexing agent for metal ions (e.g., Ca²⁺, Mg²⁺) and is used as an indicator in complexometric titrations. Eriochrome black T, Indicator forms colored complexes with metal ions through covalent coordination bonds, and indicates the endpoint of the titration by color change. Eriochrome black T, Indicator can be used as an anionic azo dye in photocatalytic degradation studies to evaluate the performance of photocatalysts. The reaction solution of Eriochrome black T, Indicator combined with Mg²⁺ is initially purple. During loop-mediated isothermal amplification (LAMP), the color changes from purple to sky blue due to the consumption of Mg²⁺ by the formation of magnesium pyrophosphate, indicating a positive reaction. The optimal concentration of Eriochrome black T, Indicator in LAMP is 60 μM, and the detection limit for Mycobacterium tuberculosis is 1 pg DNA/reaction.
