Tubulin and heat shock protein 27 (HSP27) are up-regulated in cancer cells, and play a critical role in cell division, and proliferation. Therefore, they are targets for discovery of anticancer therapy. The objective of this study is to design, characterize, and biologically evaluate the nimesulide analogues to combat female cancer such as ovarian cancer, and breast cancer. Herein, the nimesulide analogues are designed to target both tubulin and HSP27 functions. Ovarian cancer (SKOV3) and breast cancer (SKBR3) cell lines were used as surrogate models to test the nimesulide analogs biological activities using MTT assay. In the present study, four nimesulide analogues were designed, synthesized and the chemical structures were with the biological evaluation were studied. The synthesized agents were characterized by 1H-NMR, 13C-NMR, the molecular weight was confirmed using GC-MS technique, and melting point. Besides, the agent L4 structure was confirmed using X-ray crystallographic analysis. The present data revealed that nimesulide analogs have potent anticancer activity against SKOV3and SKBR3 cell lines. The IC50 values for both SKOV3 and SKBR3 cell lines treated with the agents showed a potent cell growth inhibition range of 0.23-2.02 µM and 0.50-3.73 µM respectively. In conclusion, the designed nimesulide analogues can target both tubulins, and HSP27 concurrently, and they are promising agents as future chemotherapy female cancers.

Background: According to the World Health Organization around 65% of the world's population rely on traditional medicines derived from plants for their primary healthcare needs. Plants have been used as medicines for many number of years. Sri Lanka has a rich traditional medicine history of around 3000 years and has an ample amount of plants being a tropical island. Sri Lanka has around 1430 medicinal plant species and number of these species have been used for cancer therapy by traditional medicine practitioners in the country. The cancer incidence in Sri Lanka is rising due to population aging, various life style factors such as westernized diets, smoking and lack of physical activity. Thus preventive measures such as various kinds of anticancer foods should be introduced. Aim: Tabernaemontana divaricata (TD) and Plumeria rubra (PR) which belong to the Apocynaceae family of plants and they are commonly found in Sri Lanka and they were tested to determine their anticancer activity. Methods: Leaves and stems of the plants were collected from Colombo district Sri Lanka. Ethical approval was obtained from the Department of Forest, Sri Lanka. Finely dried leaves and stems were subjected to ethanol extractions. MTT, clonogenic, cell cycle, apoptosis, gamma H2AX, cell migration, reactive oxygen species (ROS), environmental scanning electron microscopy (ESEM) were used to determine anticancer activity. Results: HER2+ SKBR3 cell line showed the best sensitivity to both plants among a panel of breast cancer cell lines. TD-GI50 leaf extract: 6.89 µg/mL ± 1.72; stem extract: 12.49 µg/mL ± 4.04) and PR-GI50 leaf extract 17.45 µg/mL ± 2.05; stem extract was not active. Clonogenic assays showed low colony formation for all active extracts in SKBR3 cells ( P ≤ 0.001). All extracts caused G1 arrests in cell cycle analysis compared with SKBR3 control ( P ≤ 0.0001). Minor amounts of apoptotic populations were observed with extracts compared with SKBR3 control ( P ≤ 0.01). Further, both leaf extracts caused minor amounts of DNA double strand breaks by gamma H2AX analysis in SKBR3 cells ( P ≤ 0.05). All extracts showed low SKBR3 cell migration ( P ≤ 0.0001). Both leaf extract were able to generate high levels of ROS in SKBR3 cells ( P ≤ 0.001). ESEM demonstrated morphologic differences in TD leaf extract treated SKBR3 cells. Conclusion: These results are promising and shows anticancer activity. Chemical compounds are being isolated from these plants. Sri Lanka is yet to develop anticancer drugs from its natural products, and these plants can be a stepping stone in the quest of finding novel therapies for cancer from Sri Lanka. Further, these results can be used to develop cancer preventive food supplements as well since the number of cancer cases are rising in the country.
