Convincing data regarding carcinogenic substances is very useful for handling materials correctly to avoid exposure to cancer-triggering substances in the body. To collect as much carcinogen data as possible, low-requirement carcinogen detection setups need to be developed. In this study, the first steps in the development of carcinogen detection through functional protein expression assessment are reported. Hydrazine sulfate, one of the well-known carcinogens chosen as a model material, was tested on germinating seeds of Raphanus sativus, L, with various concentrations, namely 0 (control), 1 mM, 10 mM, and 100 mM. Within a predetermined germination time, seeds and/or sprouts were observed and germination rate, protein concentration, and alkaline phosphatase activity were measured. The results showed that hydrazine sulfate slowed seed germination, and increased 72-h protein concentration but decreased alkaline phosphatase activity in the control group. This suggests that changes in alkaline phosphatase activity in seeds during germination have the potential to be a marker for cancer. In this research, it can be concluded that the method used can be applied as a first step to prove the carcinogenicity of a compound.

The stability of drugs and nanocarriers is a crucial factor in guaranteeing their efficacy and quality. Nanostructured lipid carriers (NLCs) as lipid-based nanocarriers provide benefits in overcoming the stability and other issues associated with the drug. Surfactants play a crucial role in imparting the desired characteristics of lipid based systems, including stability, particle size, size distribution, and zeta potential. This study aimed to develop a capsanthin-loaded NLC formulation with an optimal surfactant combination that exhibits the required properties and stability. Three formulations were prepared applying Tween 20 and Span 80 in ratios of 5:1, 2:1, and 1:1 for F1, F2, and F3, respectively. Capsanthin, as an active ingredient, originates from paprika powder. NLC properties regarding transmittance, particle size, polydispersity index (PI), zeta potential, loading capacity (LC), and loading efficiency (LE) were characterized. Furthermore, stability studies were also conducted in this research. The results showed that F1 exhibited desirable characteristics, including transmittance percentage, particle size, PI, zeta potential, LC, and LE of 87.22±2.64%, 255.4±46.88 nm, 0.54±0.13, -39.51±3.02 mV, 12.59±0.35%, and 35.40±3.07%, respectively. Moreover, the physical stability studies exhibited that F1 provided a more stable system compared to other formulations. Additionally, the chemical stability indicated that degradation occurred in the paprika powder, not in the NLC. In conclusion, NLC can protect capsanthin, as evidenced by the stable capsanthin levels in NLC compared to those in paprika powder.

Background: The first-line chemotherapy drug for breast cancer is cisplatin. However, it shows a high incidence of resistance. Therefore, Hibiscus Sabdariffa L (HS), containing strong anticancer compounds, was developed using a self-nano-emulsifying drug delivery system (SNEDDS), potentially as cisplatin co-chemotherapy. This study aimed to develop the HS SNEDDS providing anticancer activity against T47D breast cancer cells. Methods: Development of HS SNEDDS (F1-F7) with various surfactant and co-surfactant concentrations was carried out, followed by characterization of HS SNEDDS. The selected formulation was performed regarding the cytotoxicity on T47D cells and selectivity on Vero cells. Results: F7 as a selected formulation indicated a transmittance, globule size, PI, zeta potential, and emulsification time of 97.80%, 15.68 ± 0.19 nm, 0.12 ± 0.01, -8.05 ± 1.88 mV, and 24.76 ± 0.29 seconds, respectively. Furthermore, the IC50 of HS extract, HS SNEDDS, and Cisplatin on T47D cells were 0.37 ± 0.02, 0.24 ± 0.02, and 0.01 ± 0.001 mg/mL The selectivity index (SI) of HS SNEDDS and cisplatin were 108101.25 and 8351.84, respectively. Conclusion: HS SNEDDS providing the required characteristics could be obtained, and potentially be used as a co-chemotherapy of cisplatin, showing the cytotoxic effect on T47D breast cancer cells.
