Nitrovin
Nitrovin (Difurazon) is a thioredoxin reductase 1 (TrxR1) inhibitor with both antibacterial and anticancer activities. Nitrovin interacts with TrxR1 to generate reactive oxygen species (ROS), which in turn induces cytoplasmic vacuolization, activates MAPK and inhibits Alix. Nitrovin induces paraptosis-like non-apoptotic cell death, thereby exerting significant cytotoxicity against cancer cells. Nitrovin can be used in the research of heart disease and glioblastoma multiforme.

Actividad biológica
Nitrovin (0.625-10 μM; 24 h) potently reduces viability across 16 cancer cell lines (IC50=1.31-5.00 μM) and is less cytotoxic to normal LO2 and HK2 cells (IC50=5.34-6.60 μM) after 24 h treatment in vitro[1].
Nitrovin (1.25-10 μM; 24 h) concentration-dependently reduces viability and intracellular ATP levels in human glioblastoma U251 and U87 cells after 24 h treatment in vitro[1].
Nitrovin (0.625-5 μM; 24 h) induces non-apoptotic cell death in human glioblastoma U251 cells, as it does not activate caspase-3/7, cause nuclear fragmentation, or trigger Annexin V positivity after 24 h treatment in vitro[1].
Nitrovin (1.25-5 μM; 4 h) concentration-dependently increases intracellular ROS and mitochondrial superoxide levels in human glioblastoma U251 and U87 cells after 4 h treatment, and thiol-containing antioxidants NAC and GSH reverse this ROS generation in vitro[1].
Nitrovin (0.625-5 μM; 24 h) induces paraptosis-like cell death in human glioblastoma U251 and U87 cells, as Cycloheximide (HY-12320) reverses cell death and vacuolation, and nitrovin downregulates Alix expression without Alix overexpression rescuing cell death in vitro[1].
Nitrovin (5 μM; 0-24 h) induces ER stress and MAPK activation in human glioblastoma U251 cells, but these pathways do not mediate nitrovin-induced cell death in vitro[1].
Nitrovin (1.25-10 μM; 30 min-24 h) directly targets TrxR1 to inhibit its activity, and TrxR1 overexpression reverses Nitrovin-induced ROS generation and paraptosis-like cell death in human glioblastoma U251 cells in vitro[1].
Nitrovin (1-5 μM; days 6-14 of 14-day culture) promotes differentiation of CMK 6.4 cynomolgus monkey ES cells into cardiac muscle cells, as shown by increased GFP fluorescence intensity[2].
Nitrovin (5 μM; administered during days 6-14 of 18-day culture) more effectively promotes differentiation of CMK 6.4 cynomolgus monkey ES cells into cardiac muscle cells than a cytokine mixture, and exhibits a synergistic effect when combined with cytokines[2].
