IR-775 chloride
Based on 1 Customer Validation
IR-775 chloride is a cyanine dye with near-infrared absorption (Ex/Em = 775/795 nm). IR-775 chloride acts as a photosensitizer or photothermal agent, and induces apoptosis via generating ROS or exerting photothermal effects upon irradiation; its combination with 2-methoxyestradiol (HY-12033) inhibits SOD2 to enhance photodynamic therapy (PDT) efficacy, and its liposomal encapsulation enables phytotherapy-photothermal therapy (PTT) synergy. IR-775 chloride is applicable for investigating PDT/PTT and near-infrared fluorescence imaging in ovarian cancer and breast cancer.

Biological Activity
Description
In Vitro
IR-775 (2-10 μM; 24-72 h) chloride is a potent photosensitizer in proliferative diabetic retinopathy (PDR). It reduces the viability of human ovarian adenocarcinoma cell line (SKOV-3) and human breast adenocarcinoma cell line (MDA-MB-231) in a time-dependent manner, and exhibits stronger cytotoxicity when combined with 2-methoxyestradiol plus irradiation[1].
IR-775 (6 μM; 2-24 h) chloride accumulates in non-nuclear organelles of human ovarian adenocarcinoma cell line (SKOV-3) and human breast adenocarcinoma cell line (MDA MB-231), and an increase in uptake is observed during the 2 h to 24 h incubation period[1].

-
Cell Line:human ovarian adenocarcinoma (SKOV-3), human breast adenocarcinoma (MDA MB-231)
-
Concentration:2 μM; 4 μM; 6 μM; 8 μM; 10 μM
-
Incubation Time:24 h (pre-incubation); 24 h (post-irradiation incubation); 72 h (post-irradiation incubation)
-
Result:Reduced viability in both cell lines when treated with 2-10 μM for 24 h.
Identified 6 μM as the non-toxic dose.
Reduced MDA MB-231 viability to ~80% and SKOV-3 viability to ~88% after 24 h post-irradiation incubation when used alone in photodynamic reaction (PDR).
Reduced MDA MB-231 viability to 53% after 24 h and 33% after 72 h post-irradiation incubation, and SKOV-3 viability to 60% after 24 h and 45% after 72 h post-irradiation incubation when combined with 2-methoxyestradiol and irradiation.
Showed minimal cytotoxicity alone without irradiation.

Cell Line:human ovarian adenocarcinoma (SKOV-3), human breast adenocarcinoma (MDA MB-231)
-
Concentration:6 μM
-
Incubation Time:24 h (pre-incubation); 24 h (post-irradiation incubation); 72 h (post-irradiation incubation)
-
Result:Reduced SOD2 positive staining to 30% (weak intensity) at 24 h post-irradiation and 50% (weak intensity) at 72 h post-irradiation, while increasing caspase-12 positive staining to 80% (strong intensity) at both 24 h and 72 h post-irradiation in SKOV-3 cells.
Reduced SOD2 positive staining to 25% (moderate intensity) at 24 h post-irradiation, which returned to 100% (weak intensity) at 72 h post-irradiation, while increasing caspase-12 positive staining to 25% (weak-moderate intensity) at 24 h post-irradiation and 100% (strong intensity) at 72 h post-irradiation in MDA MB-231 cells.
Showed minimal caspase-12 staining and full SOD2 staining in unirradiated controls of both cell lines.
