IR-780
Based on 7 publication(s) in Google Scholar
IR-780 is a near-infrared fluorescent probe for in vivo imaging of tumor cells. IR-780 is transported into tumor cells via OATPs and ABCB10, with uptake dependent on glycolytic activity and plasma membrane potential. IR-780 preferentially accumulates in tumor cell mitochondria, including those of drug-resistant cancer cells, without chemical conjugation. IR-780 generates reactive oxygen species (ROS), induces hyperthermia and apoptosis, inhibits tumor growth and recurrence, and modulates HSP70 expression upon ultrasound or 808 nm laser exposure. IR-780 acts as a sonosensitizer, photodynamic and photothermal agent, and drug delivery carrier, with low acute imaging-dose toxicity and rapid vital organ clearance. IR-780 can be used for the research of cancer, such as breast cancer, lung cancer, and non-small cell lung cancer (NSCLC).

IR-780 (10 μM; 15 min at 37°C) preferentially accumulates in the mitochondria of human MCF-7, HeLa, and MG-63 tumor cells via organic anion transporter peptide-mediated uptake[1].
IR-780 acts as an SDT agent in 4T1 breast cancer cells, generating increased ROS upon US irradiation[2].
IR-780 selectively accumulates in the mitochondria of A549/DR drug-resistant lung cancer cells, inhibiting cell growth and promoting apoptosis by disrupting mitochondrial function[2].
IR-780 (4-16 μM; 1-3 h (flow cytometry); 1 h (confocal microscopy)) exhibited dose- and time-dependent uptake by 4T1 breast cancer cells, with higher concentrations and longer incubation times leading to greater uptake[3].
IR-780 (10 μM; 3 h (pre-incubation); 20 s US irradiation)-induced sonodynamic cell damage in 4T1 breast cancer cells is inhibited by histidine and SOD but not mannitol[3].
IR-780 (2.5-40 μM; 48-72 h) inhibits the viability of human cancer cell lines (A549, H460, HepG2, U251, MCF-7) with A549 cells being the most susceptible[4].
IR-780 (10 μM; 4 h) significantly inhibits the clone formation ability of A549/DR cells[4].
IR-780 (10 μM; 12 h) significantly inhibits the migration ability of A549/DR cells[4].
IR-780 (20 μM; 20 min) increases ROS production in A549/DR cells[4].
IR-780 (10-20 μM; 24 h) decreases the mitochondrial membrane potential of A549/DR cells, with significant reduction at 20 μM[4].
IR-780 (20 μM; 24 h) induces apoptosis in over 60% of A549/DR cells after 24 h[4].
IR-780 (4-16 μM; 20-40 s ultrasound irradiation) acted as a sonosensitizer to significantly reduce 4T1 murine breast cancer cell viability and induce apoptosis/necrosis in a dose- and ultrasound time-dependent manner, with higher concentrations and longer ultrasound exposure causing greater cytotoxicity[9].
IR-780 (5 μg/mL equivalent free IR-780; 10-120 min) loaded into heparin-folic acid nanoparticles exhibits time-dependent fluorescence activation in MCF-7 cells, with fluorescence intensity increasing significantly over 120 min of incubation, indicating cellular uptake and release of active IR-780[11].

IR-780 (5.74 μmol/kg; i.v.; every three days; 15 days; 808 nm laser irradiation) exerts tumor growth inhibition in Hep1-6 tumor-bearing BALB/c mice[6].
IR-780 (80 μg; intratumoral injection; followed by ultrasound irradiation at 2 W/cm2 for 4 minutes) combined with US irradiation induces significant breast tumor growth inhibition in BALB/c mice, reducing mean tumor volume to 40.7 mm3 at day 30 and achieving a 50.9 % tumor cell apoptotic index, with no significant body weight changes[9].
IR-780 (0.7 mg/kg; i.v.; single dose) accumulates in MCF-7 breast cancer xenografts, enabling NIR fluorescence imaging, though with lower tumor retention than IR-780 delivered via HF-IR-780 NPs[11].
