Anticancer agent 360 is a broad-spectrum antibacterial agent. Anticancer agent 360 binds to the ATP pocket of the GyrB subunit of DNA gyrase via an Arg84 salt bridge, interfering with gyrase-dependent DNA supercoiling. Anticancer agent 360 disrupts bacterial biofilms and inhibits the metabolic activity of respiratory chain dehydrogenases. Anticancer agent 360 exhibits activity against Gram-positive bacteria, Gram-negative bacteria, and fungal strains. Anticancer agent 360 exerts selective cytotoxicity against liver cancer cells. Anticancer agent 360 can be used in studies related to bacterial infections and liver cancer.

FAP-IN-4 (Comp 10) is a fibroblast activation protein (FAP) inhibitor and a ¹⁸F-labeled PET tracer targeting FAP. FAP-IN-4 can be used for cancer research.

1-Methyl-2-pentyl-4(1H)-quinolinone, a quinolone alkaloid isolated from the fruits of Evodia Rutaecarpa, possesses antibacterial and cytotoxic activities for cancer cells.

h-NTPDase-IN-4 (compound 4c) is a pan-inhibitor of NTPDase with IC50s of 3.58 μM (h-NTPDase1), 10.21 μM (h-NTPDase2), 0.13 μM (h-NTPDase3), 13.57 μM (h- NTPDase8).

EGFR-IN-191 is an anti-tumor agent targeting both EGFR and AKT. EGFR-IN-191 exerts its anti-tumor activity by inducing DNA damage, apoptosis, cell cycle arrest, and inhibition of the PI3K/AKT-EGFR signaling pathway in tumor cells. EGFR-IN-191 can be used in the study of tumors such as triple-negative breast cancer.

MJ-33 is a competitive phospholipase A₂ (PLA₂) inhibitor with an IC₅₀ of 0.3 μM. MJ-33 inhibits the activation of NOX2 by blocking the PLA₂ activity of Prdx6, thereby reducing the production of ROS. MJ-33 effectively inhibits the activity of acidic PLA₂ (pH 4.0), reduces the degradation of pulmonary surfactant phosphatidylcholine (PC), but has no effect on alkaline PLA₂ (pH 8.5). MJ-33 significantly alleviates lung oxidative damage induced by ischemia-reperfusion (I/R). MJ-33 significantly inhibits the invasive, migratory and adhesive abilities of prostate cancer cells by suppressing the MAPK, AKT, NF-κB and AP-1 signaling pathways. MJ-33 can be used to study ROS-related diseases and prostate cancer.

SUCNR1 antagonist-1 is an orally active SUCNR1 antagonist. SUCNR1 antagonist-1 forms stable, water-bridged hydrogen bonds with key residue Glu22^1.31 to stabilize binding conformation and modulates protein conformational flexibility. SUCNR1 antagonist-1 blocks succinate-mediated SUCNR1 signaling and induces cell apoptosis. SUCNR1 antagonist-1 can be used for the research of colorectal carcinoma.

Erythromycin A dihydrate is a macrolide antibiotic produced by actinomycete Streptomyces erythreus with a broad spectrum of antimicrobial activity. Erythromycin A dihydrate binds to bacterial 50S ribosomal subunits and inhibits RNA-dependent protein synthesis by blockage of transpeptidation and/or translocation reactions, without affecting synthesis of nucleic acid^[1][2]. Erythromycin A dihydrate also exhibits antitumor and neuroprotective effect in different fields of research^[3][4].

4-Acetylaminoantipyrine-d₃ is the deuterium labeled 4-Acetylaminoantipyrine (HY-W268542). 4-Acetylaminoantipyrine (4-AA) is a derivative of antipyrine (HY-B0171). 4-Acetylaminoantipyrine acts as a PGE2-dependent blocker and inhibitor of cyclooxygenase (COX). 4-Acetylaminoantipyrine can inhibit Cu/ZnSOD. 4-Acetylaminoantipyrine can spontaneously bind with bovine serum albumin (BSA) and alter its conformation.

BTF-DNBS is a glutathione (GSH)-responsive small-molecule photosensitizer (PS). BTF-DNBS disrupts mitochondrial function and triggers Golgi-mediated pyroptosis, serving as a reactive oxygen species (ROS) generator. BTF-DNBS is promising for research of cancers.

Aurein 3.3 is an antibiotic antimicrobial peptide. Aurein 3.3 also has anticancer activity.

CTB006 is a monoclonal antibody targeting a humanized chimeric recombinant anti-DR5. CTB006 specifically binds to and activates DR5, thereby inducing tumor cell apoptosis, inhibiting tumor growth and reducing tumor drug resistance. ¹⁷⁷Lu-radiolabeled CTB006 can deliver targeted radiotherapy to tumor cells; while ⁸⁹Zr- or ¹⁷⁷Lu-labeled CTB006 can serve as a PET/CT imaging agent for detecting DR5 expression levels in preclinical tumor models and screening cancers with DR5 overexpression. CTB006 can be applied to research related to gastrointestinal cancer, colorectal cancer and other solid tumors.
