Cobra Venom Factor (CVF) is a selective activator targeting complement components C3, C5, and factor B in the complement system. After binding to factor B, Cobra Venom Factor is cleaved by factor D, forming a stable C3/C5 convertase resistant to regulatory proteins H and I. This continuously hydrolyzes C3 and C5, depleting serum complement while inducing neutrophil migration, vascular leakage, and increased TNF-α levels. Cobra Venom Factor can be used to deplete complement and mimic complement activation-related pathological states, and is applied in animal models of complement-mediated diseases such as acute respiratory distress syndrome (ARDS), sepsis, and shock. Cobra Venom Factor can be isolated from the venom of cobras (e.g., Naja atra, Naja melanoleuca, Naja kaouthia, etc.).

Mimosine, a tyrosine analog , can act as an antioxidant by its potent iron-binding activity. Mimosine is a known chelator of Fe(III). Mimosine induces apoptosis through metal ion chelation, mitochondrial activation and ROS production in human leukemic cells. Anti-cancer, antiinflammation.

Taurochenodeoxycholic acid (12-Deoxycholyltaurine) sodium is one of the main bioactive substances of animals' bile acid. Taurochenodeoxycholic acid sodium induces apoptosis and shows obvious anti-inflammatory and immune regulation properties.

Mitiperstat (AZD4831) is an effective oral inhibitor of myeloperoxidase (MPO). Mitiperstat inhibits MPO and thyroid peroxidase (TPO) with IC₅₀s of 1.5 nM and 0.69 μM. Mitiperstat exhibits a weak inhibitory activity against CYP3A4 with an IC₅₀ of 6 μM. Mitiperstat can reduce inflammation and improve microvascular function, and it can be used in studies related to heart failure, preserved or mildly reduced ejection fraction, non-alcoholic fatty liver disease, and chronic obstructive pulmonary disease.

Flurbiprofen (dl-Flurbiprofen) is a potent, orally active nonsteroidal anti-inflammatory agent (NSAIA/NSAID), with antipyretic and analgesic activities. Flurbiprofen is commonly used for the research of inflammatory diseases, including osteoarthritis and rheumatoid arthritis. Flurbiprofen is a non-selective cyclooxygenase (COX) inhibitor that can be used for the research of colorectal cancer.

Tazarotene (AGN 190168) is a selective retinoic acid receptor (RAR) agonist for the treatment of plaque psoriasis and acne vulgaris. Tazarotene is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

Tetrahydrocurcumin is a Curcuminoid found in turmeric (Curcuma longa) that is produced by the reduction of Curcumin. Tetrahydrocurcumin inhibit CYP2C9 and CYP3A4.

Meprednisone is a glucocorticoid and a methylated derivative of Prednisone (HY-B0214). Meprednisone modulates glucocorticoid receptor. Meprednisone is orally active.

TNF-α-IN-2 is a potent and orally active inhibitor of tumor necrosis factor alpha (TNFα), with an IC₅₀ of 25 nM in the HTRF assay. TNF-α-IN-2 distorts the TNFα trimer upon binding, leading to aberrant signaling when the trimer binds to TNFR1. TNF-α-IN-2 can be used for the research of rheumatoid arthritis.

LY3509754 (IL-17A inhibitor 1) is a IL-17A inhibitor, with IC₅₀ values of <9.45 nM and 9.3 nM in alphalisa assay and HT-29 cells.

Cusatuzumab (ARGX-110) is a selective competitive blocker targeting CD70 (with an equilibrium dissociation constant of 17 pM for binding to human CD70). Cusatuzumab also possesses enhanced antibody-dependent cell-mediated cytotoxicity (ADCC) activity. It is a humanized IgG1 monoclonal antibody, artificially synthesized through humanization and genetic engineering modifications (CH2 region mutation to enhance effector function). Cusatuzumab has a dual mechanism of action: firstly, it competitively blocks the interaction between CD70 and CD27, inhibiting the CD27-NF-κB signaling pathway, reducing regulatory T cell (Treg) activation and tumor cell proliferation; secondly, by enhancing binding to FcγRIIIa, it mediates ADCC and antibody-dependent cellular phagocytosis (ADCP), directly lysing CD70-positive tumor cells. Cusatuzumab can efficiently eliminate leukemia stem cells (LSCs), induce tumor cell differentiation and apoptosis, restore immune surveillance, and target CD70-positive tumors. Cusatuzumab is used in the study of acute myeloid leukemia (AML).
