Nitroaspirin
Based on 1 Customer Validation
Nitroaspirin (NCX 4016) is an orally active inhibitor of ARG1 and NOS2. Nitroaspirin reduces ARG1 enzymatic activity via the STAT6-mediated signaling pathway, and feedback-inhibits the catalytic activity of NOS2 in a NO-releasing group-dependent manner. Nitroaspirin continuously releases intracellular NO, inducing redox-dependent loss of cell viability. Nitroaspirin also exerts anti-angiogenic effects by causing endothelial barrier dysfunction, and effectively inhibits the proliferation of Cisplatin (HY-17394)-resistant human ovarian cancer cells. Nitroaspirin can be used in research related to colon cancer, breast cancer and Cisplatin-resistant human ovarian cancer.

Nitroaspirin (NCX 4016) (2 mM; 3 days) restores anti-CD3/anti-CD28-induced proliferation of BALB-c splenocytes inhibited by γ-irradiated MSC-2 myeloid suppressor cells[1].
Nitroaspirin (50-500 μM; 1-3 h) induces dose- and time-dependent loss of redox-dependent viability in BLMVECs, causing up to 74% viability loss at 100 μM after 3 h[2].
Nitroaspirin (100 μM; 2 h) induces a 4.7-fold increase in intracellular NO generation in BLMVECs after 2 h[2].
Nitroaspirin (100 μM; 1-2 h) induces time-dependent endothelial barrier dysfunction in BLMVEC monolayers, as measured by decreased TER after 1 and 2 h of treatment[2].
Nitroaspirin (100-500 μM; 2 h) induces dose-dependent actin cytoskeletal reorganization, including actin stress fiber formation and paracellular gap development, in BLMVECs after 2 h of treatment[2].
Nitroaspirin (25-100 μM; 10 h) inhibits in vitro angiogenesis in a dose-dependent manner in HUVECs and BLMVECs, with near-complete inhibition at 100 μM after 10 h of treatment[2].

Cell Line:bovine lung microvascular endothelial cells (BLMVECs)
-
Concentration:50-500 μM (2 h); 100 μM (1-3 h)
-
Incubation Time:1-3 h (100 μM); 2 h (50-500 μM)
-
Result:Induced a dose-dependent loss of cell viability: caused a 28% loss at 50 μM, 67% loss at 100 μM, and 70% loss at 500 μM relative to vehicle-treated controls after 2 h.
Caused a 19% loss of viability at 100 μM after 1 h, a 72% loss after 2 h, and a 74% loss after 3 h, with significantly greater viability loss at 2 and 3 h compared to 1 h.

Result:Caused a significant loss of cell viability, which was completely attenuated by pretreatment with 5 mM NAC.
Resulted in viability slightly higher (12% increase) than vehicle-treated controls in NAC-pretreated cells.

-
Dosage:6.25 mg/kg; 12.5 mg/kg; 25 mg/kg; 50 mg/kg
-
Administration:p.o.; twice daily; 9 days
-
Result:Restored compromised alloreactive CTL responses in tumor-bearing mice at 12.5, 25, and 50 mg/kg, with cytotoxicity levels approaching those of tumor-free mice; showed minimal activity at 6.25 mg/kg.
Reduced ARG activity in CD11b+ splenocytes from tumor-bearing mice from ~40 mU/106 cells to ~5 mU/106 cells, equivalent to tumor-free mice.
Reduced NOS activity in CD11b+ splenocytes from tumor-bearing mice from ~25 μM NO2-/NO3- to ~5 μM NO2-/NO3-, equivalent to tumor-free mice.
Completely abrogated intratumoral peroxynitrite production, as evidenced by the near disappearance of nitrotyrosine staining in tumor sections.
Reduced intratumoral CD11b+Gr-1+ myeloid suppressor cell content by ~41% (from 58.5 to 34.57 cells per ×400 field).
Caused only slight tumor growth retardation, with no significant difference in survival rates after treatment cessation.
