    (S)-10-Hydroxycamptothecin-d5

    10-HCPT-d5; 10-Hydroxycamptothecin-d5

    Topoisomerase Apoptosis Cancer
    (S)-10-Hydroxycamptothecin-d5 (10-HCPT-d5) is the deuterium labeled (S)-10-Hydroxycamptothecin. (S)-10-Hydroxycamptothecin (10-HCPT) is a DNA topoisomerase I inhibitor. (S)-10-Hydroxycamptothecin exhibits a remarkable apoptosis-inducing effect. (S)-10-Hydroxycamptothecin has the potential for hepatoma, gastric carcinoma, colon cancer and leukaemia research.

    Trovafloxacin

    Bacterial Topoisomerase Antibiotic Infection
    Trovafloxacin is a broad-spectrum quinolone antibiotic with potent activity against Gram-positive, Gram-negative and anaerobic organisms. Trovafloxacin blocks the DNA gyrase and topoisomerase IV activity. Trovafloxacin is also a potent, selective and orally active pannexin 1 channel (PANX1) inhibitor with an IC50 of 4 μM for PANX1 inward current. Trovafloxacin does not inhibit connexin 43 gap junction or PANX2. Trovafloxacin leads to dysregulated fragmentation of apoptotic cells by inhibiting PANX1.

    Trovafloxacin mesylate

    Bacterial Topoisomerase Antibiotic Infection
    Trovafloxacin mesylate is a broad-spectrum quinolone antibiotic with potent activity against Gram-positive, Gram-negative and anaerobic organisms. Trovafloxacin mesylate blocks the DNA gyrase and topoisomerase IV activity. Trovafloxacin mesylate is also a potent, selective and orally active pannexin 1 channel (PANX1) inhibitor with an IC50 of 4 μM for PANX1 inward current. Trovafloxacin mesylate does not inhibit connexin 43 gap junction or PANX2. Trovafloxacin mesylate leads to dysregulated fragmentation of apoptotic cells by inhibiting PANX1.

    Trovafloxacin-d4 mesylate

    Bacterial Topoisomerase Antibiotic Infection
    Trovafloxacin-d4 mesylate is the deuterium labeled Trovafloxacin mesylate. Trovafloxacin mesylate is a broad-spectrum quinolone antibiotic with potent activity against Gram-positive, Gram-negative and anaerobic organisms. Trovafloxacin mesylate blocks the DNA gyrase and topoisomerase IV activity. Trovafloxacin mesylate is also a potent, selective and orally active pannexin 1 channel (PANX1) inhibitor with an IC50 of 4 μM for PANX1 inward current.

    CL2A-SN-38

    Drug-Linker Conjugates for ADC Cancer Inflammation/Immunology
    CL2A-SN-38 is a drug-linker conjugate composed of a potent a DNA Topoisomerase I inhibitor SN-38 and a linker CL2A to make antibody drug conjugate (ADC). CL2A-SN-38 provides significant and specific antitumor effects against a range of human solid tumor types. CL2A is a nonclaevable complicated PEG8- and triazole-containing PABC-peptide-mc linker. CL2A is cleavable through pH sensitivity, giving rise to bystander effect, and binds the antibody at a cysteine residue via a disulfide bond.

    Enoxacin-d8

    Bacterial DNA/RNA Synthesis MicroRNA Antibiotic Cancer Infection
    Enoxacin-d8 (AT 2266-d8) is the deuterium labeled Enoxacin. Enoxacin (AT 2266), a fluoroquinolone, interferes with DNA replication and inhibits bacterial DNA gyrase (IC50=126 µg/ml) and topoisomerase IV (IC50=26.5 µg/ml). Enoxacin is a miRNA processing activator and enhances siRNA-mediated mRNA degradation and promotes the biogenesis of endogenous miRNAs. Enoxacin has potent activities against gram-positive and -negative bacteria. Enoxacin is a cancer-specific growth inhibitor that acts by enhancing TAR RNA-binding protein 2 (TRBP)-mediated microRNA processing.
