Lavofloxacin lactate ((-)-ofloxacin lactate) is a class of broad-spectrum antimicrobials that can kill or inhibit a variety of bacteria. Lavofloxacin lactate binds to DNA rotase and topoisomerase IV, resulting in blocked DNA replication and repair, thus inhibiting bacterial growth. Lavofloxacin lactate can be used to study resistance mechanisms in bacteria, including studying resistance genes and mutations .

Cyclo(Phe-Pro) (Cyclo(phenylalanylprolyl)) is a quorum-sensing molecule of Vibrio vulnificus that specifically interacts with RIG-I, inhibiting RIG-I polyubiquitination, suppressing IRF-3 activation, and reducing type I interferon production. Cyclo(Phe-Pro) enhances susceptibility to HCV and influenza virus and also alleviates plant aluminum toxicity stress. The mechanism of Cyclo(Phe-Pro) involves the regulation of host immune signaling pathways, bacterial virulence gene expression, and plant antioxidant systems, making it a promising candidate for research in viral infections, bacterial virulence regulation, and agricultural stress resistance .

Cetuximab MMAE is an antibody-drug conjugate (ADC) targeting EGFR, formed by the random conjugation of the Cetuximab (HY-P9905) antibody and VcMMAE (HY-15575) via reduced interchain cysteines. Cetuximab MMAE binds to EGFR, blocks ligand interactions, inhibits downstream signal transduction, mediates receptor internalization, and delivers MMAE to induce G2/M phase cell cycle arrest, inhibit microtubule polymerization, interfere with mitosis, and exert radiosensitizing effects. Cetuximab MMAE limits the toxicity of free MMAE to EGFR-expressing cells and circumvents EGFR resistance mechanisms. Cetuximab MMAE is applicable to research related to EGFR + tumors .

Thifluzamide is a fungicide that inhibits fungal respiration by blocking the ubiquinone-binding site in mitochondrial complex II. Thifluzamide exhibits significant activity against Basidiomycota pathogens (such as Rhizoctonia cerealis, Ustilago and Puccinia genera) and is commonly used in studies on wheat sharp eyespot. Thifluzamide displays a dual mechanism in regulating lipid metabolism: it reduces fatty acid synthase activity to inhibit endogenous fatty acid synthesis, and increases carnitine palmitoyltransferase-I activity to accelerate fatty acid β-oxidation, thereby reducing total cholesterol and triglyceride levels in the liver. Thifluzamide also induces hepatotoxicity in zebrafish models and carries a risk of developmental toxicity. Thifluzamide inhibition of Rhizoctonia cerealis may result in low to moderate levels of drug resistance, leading to the generation of stable drug-resistant mutants .

DpC is a selective, orally active iron chelator with anticancer activity. DpC acts on signaling pathway-related targets such as JNK, NF-κB, and its activity is competitively inhibited by another iron chelator Dp44mT (HY-18973). By chelating intracellular iron and copper ions in tumor cells to form redox-active complexes, DpC induces oxidative stress, activates the JNK, NF-κB pathways and downregulates IκBα, upregulates the expressions of neuroglobin and cytoglobin, activates caspase 3/9 to induce tumor cell apoptosis. It also overcomes P-glycoprotein-mediated multidrug resistance through a lysosome-targeting mechanism, and exhibits broad-spectrum synergistic effects when combined with various chemotherapeutic agents. DpC inhibits tumor metastasis and increases TNF-α levels in the tumor microenvironment to enhance endogenous immune responses. DpC is applicable to the research of various malignancies including neuroblastoma, pancreatic cancer, prostate cancer, lung cancer, and breast cancer .

CPI1 is a multidrug resistance protein 1 (MRP1) inhibitor with a Ki value of 100 nM. CPI1 binds to the same substrate-binding site as leukotriene C4, stabilizes MRP1 in an apo-like inward-facing conformation, blocks the conformational changes required for ATP hydrolysis and substrate transport, and inhibits the ATPase activity of human and bovine MRP1. CPI1 serves as a tool for investigating the substrate transport mechanism of MRP1. CPI1 is applicable to research related to cancer multidrug resistance .

Dihydralazine sulfate is an antihypertensive hydrazine derivative and also a low-potency genotoxic agent. Dihydralazine sulfate is a direct-acting mutagen with a mixed gene mutation mechanism, which induces DNA fragmentation in the lung, kidney and spleen of mice, and induces sister chromatid exchange in mouse bone marrow cells. Dihydralazine sulfate specifically kills DNA repair-deficient bacteria. Dihydralazine sulfate is a vasodilator and antihypertensive agent that reduces systemic vascular resistance, increases cardiac output and heart rate, thereby lowering blood pressure. Dihydralazine sulfate can be used in research related to hypertension and severe early-onset preeclampsia .

Synonyms: Dihydrocinchonine
Hydrocinchonine (Dihydrocinchonine) is a multidrug resistance (MDR)-reversal agent. Hydrocinchonine directly inhibits the function and expression of P-gp, which is the mechanism by which it reverses MDR. Hydrocinchonine exerts synergistic apoptotic effect with Paclitaxel (HY-B0015) in MES-SA/DX5 cells. Hydrocinchonine can be used for the study of gynecological malignant tumors (such as uterine sarcoma) with drug resistance caused by excessive expression of P-gp .
