Background:
Cancer is a far-reaching and lethal but curable disease. Researchers have investigated numerous anticancer agents with only a few commercially available effective drugs which are very costly.
Objective:
Herein, we report the synthesis , characterization and anti cancer assays of a series of novel dithiocarbamates derivatives.
Methods:
All compounds were synthesized from different secondary amines and substituted benzyl chlorides in a single step. The structures of newly synthesized dithiocarbamate derivatives were confirmed by spectroscopic techniques (IR, NMR and HR-MS).
Results:
The synthesized compounds showed a significant anti-proliferative effect in cancer cells (HeLa) with the maximum inhibitory activity of compound SHD-2 with an IC50 = 0.31 ± 0.09 μM. However, the same compound exhibited 19.2% inhibition towards Baby Hamster Kidney fibroblasts (BHK-21), normal cell lines. Moreover, quantification of cellular DNA by flow cytometry for the evaluation of pro-apoptotic activity in HeLa cells demonstrates that arrest in cell cycle along with apoptosis advance towards drug cytotoxicity. However, molecular docking studies of the potent compound suggested that it binds to the major groove of the DNA.
Conclusion:
The cytotoxic and pro-apoptotic potential of the potent inhibitor may be further investigated in the animal models to advance their anti-cancer prospective.
Insights
Novel dithiocarbamate derivatives show potent anticancer activity against HeLa cells, with compound SHD-2 demonstrating significant anti-proliferative and pro-apoptotic effects. Further investigation in animal models is warranted for their anticancer prospective.
Area of Science:
- Medicinal Chemistry
- Drug Discovery
- Cancer Research
Background:
- Cancer remains a significant global health challenge, necessitating the development of effective and affordable treatments.
- Existing anticancer drugs are often costly and limited in availability, driving research into novel therapeutic agents.
Purpose of the Study:
- To synthesize and characterize a new series of dithiocarbamate derivatives.
- To evaluate the anticancer activity of these novel compounds against cancer cell lines.
Main Methods:
- Compounds were synthesized in a single step using secondary amines and substituted benzyl chlorides.
- Structures were confirmed using spectroscopic techniques including IR, NMR, and HR-MS.
- Anticancer activity was assessed via cell proliferation assays, flow cytometry, and molecular docking.
Main Results:
- The synthesized dithiocarbamates exhibited significant anti-proliferative effects on HeLa cancer cells.
- Compound SHD-2 displayed maximum inhibitory activity with an IC50 of 0.31 ± 0.09 μM and minimal toxicity to normal BHK-21 cells.
- Flow cytometry revealed that SHD-2 induces cell cycle arrest and apoptosis in HeLa cells, suggesting a mechanism for its cytotoxicity.
Conclusions:
- The potent dithiocarbamate derivative SHD-2 shows promising cytotoxic and pro-apoptotic potential.
- Further preclinical studies in animal models are recommended to explore the anticancer efficacy of these compounds.
