Globally, colorectal cancer is the most prevalent type of cancer. Even though multiple treatments such as surgery, radiation, chemotherapy, and immunotherapy are available, the adverse effects caused in patients seem remarkable. Therefore, the current work was deliberated to prepare the metabolites (cell-free supernatant-CFS) from Weissella cibaria RK-3-1 to conduct in-silico and in-vitro-based anticancer assays. First, the active biomolecules present in the CFS were screened using a GC-MS analyzer. In addition, in-silico-based pharmacokinetic and docking studies were performed to confirm the anticancer potential of metabolites. In-silico results suggested that the bioactive compounds such as filicinic acid, dibutyl phthalate, and 4H-pyran-4-one,2,3-dihydro-3,5-dihydroxy-6-methyl present in CFS possessed significant molecular docking interactions with anticancer hub proteins. Furthermore, in-vitro results displayed the inhibition of cell proliferation in HT-29 cells at an IC50 value of 22.5 ± 1.3 µg/ml with the least significant effect on HEK-293 cell lines. Moreover, bacterial metabolites-controlled cell proliferation during the cell cycle's synthesis phase (S). Furthermore, the gene expression results confirm the increased expression of Bad, Bax, Bcl2, caspase-3, and cytochrome-C genes involved in the intrinsic apoptotic pathway. Hence, our findings from the in-silico and the in-vitro study confirm the anticancer potential of cell free-supernatant synthesized by W. cibaria., (© 2023.

Sodium-ion batteries are promising futuristic large-scale energy-storage devices because of the abundance and low cost of sodium. However, the development and commercialization of the sodium-ion battery solely depends on the use of high-capacity electrode materials. Among the various metal oxides, SnO 2 has a high theoretical specific capacity for sodium-ion battery. However, the enormous volume expansion and low electrical conductivity of SnO 2 hinder its capability to reach the predicted theoretical value. Although different nanostructured designs of electrode materials like SnO 2 nanocomposites have been studied, the effects of other cell components like electrolyte and binder on the specific capacity and cyclic stability are yet to be understood. In the present study, we have investigated the synergistic effect of electrolyte and binder on the performance enhancement of SnO 2 supported on the intertwined network structure of reduced graphene oxide partially open multiwalled carbon nanotube hybrid as anode in sodium-ion battery. Our result shows that sodium carboxyl methyl cellulose and ethylene carbonate/diethyl carbonate as the electrolyte solvent offers a high specific capacity of 688 mAh g -1 and a satisfactory cyclic stability for 500 cycles. This is about 56% enhancement in specific capacity compared to the use of poly(vinylidene fluoride) binder and propylene carbonate as the electrolyte solvent. The present study provides a better understanding of the synergistic role of electrolyte and binder for the development of metal-oxide-based electrode materials for the advancement of the commercialization of sodium-ion battery., Competing Interests: The authors declare no competing financial interest.
