Abstract:
Bladder cancer is a worldwide problem and improved therapies are urgently needed. In the search for newer strong antitumor compounds, herein, we present the study of three nitric oxide-releasing compounds and evaluate them as possible therapies for this malignancy. Bladder cancer cell lines T24 and 253J were used to evaluate the antiproliferative, antimigratory, and genotoxic effects of compounds. Moreover, we determined the NF-κB pathway inhibition, and finally, the survivin downregulation exerted by our molecules. The results revealed that compounds 1 and 3 exerted a high antiproliferative activity against bladder cancer cells through DNA damage and survivin downregulation. In addition, compound 3 reduced bladder cancer cell migration. We found that nitric oxide donors are promising molecules for the development of a new therapeutic targeting the underlying mechanisms of tumorigenesis and progression of bladder cancer.
Insights
Nitric oxide-releasing compounds 1 and 3 show significant potential against bladder cancer by inhibiting cell growth and reducing survivin. Compound 3 also decreased cancer cell migration, offering new therapeutic avenues.
Area of Science:
- Oncology
- Pharmacology
Background:
- Bladder cancer presents a significant global health challenge requiring novel therapeutic strategies.
- Existing treatments necessitate the development of new compounds with improved efficacy.
Purpose of the Study:
- To investigate the antitumor potential of three novel nitric oxide-releasing compounds against bladder cancer.
- To evaluate the antiproliferative, antimigratory, and genotoxic effects of these compounds on bladder cancer cell lines.
Main Methods:
- Utilized T24 and 253J bladder cancer cell lines to assess compound effects.
- Determined compound-induced DNA damage, NF-κB pathway inhibition, and survivin downregulation.
- Evaluated the impact of compounds on cell proliferation and migration.
Main Results:
- Compounds 1 and 3 demonstrated potent antiproliferative activity against bladder cancer cells.
- Both compounds induced DNA damage and downregulated survivin expression.
- Compound 3 significantly inhibited bladder cancer cell migration.
Conclusions:
- Nitric oxide donors show promise as a new therapeutic approach for bladder cancer.
