Anti-lung Cancer, Anti-microbial, Anti-α-glucosidase, Anti-sorbitol Dehydrogenase, and in silico Studies of Wogonoside and Isoliquiritigenin as Natural Compounds.

Natural substances have long been used in cancer treatment, particularly in Chinese or Indian traditional medicine. Natural compounds are defined as chemical molecules that are found in fungus, marine animals, plants, or bacteria and have significant biological and pharmacological effects. Wogonoside and isoliquiritigenin are two well-known examples of plant-derived chemicals. Several modern anti-cancer medications also come from natural sources. The mic test was used to conduct tests on various natural substances' antimicrobial and antifungal properties. MTT assay was used on lung cancer, and normal (HUVEC) cell lines for analyzing of cytotoxicity and anti-lung cancer effects of Wogonoside and Isoliquiritigenin. These Wogonoside and Isoliquiritigenin had high cell death and anti-lung cancer effects against SPC-A-1, SK-LU-1, and 95D cell lines. Among the above cell lines, the best result of anti-cancer properties of Wogonoside and Isoliquiritigenin was gained in the cell line of KATO III. We examined the inhibition effects on two important enzymes using these two compounds and determined the results. PnPG and NADPH were used as substrates for enzymes. IC50 of Wogonoside and Isoliquiritigenin compounds were 18.25±4.18 and 112.64±16.02 nM for α-glucosidase and 54.72±8.61 and 47.12±11.56 nM for sorbitol dehydrogenase, respectively. For Wogonoside, gram-negative bacteria (K. pneumoniae and E. coli) had MIC values of 9.75±0.95 and 13.77±1.43 µg/mL, gram-positive bacteria (E. faecalis and S. aureus) of 37.02±4.52 and 24.85±3.64 µg/mL, respectively. Finally, molecular docking was done for enzyme results and anticancer results. Results of enzymes and antibacterial, antifungal were in level of micromolar that is good impacts. These natural compounds may be anti-diabetic, anticancer, antibacterial candidates for drug design.

Overexpression of RNF126 is associated with poor prognosis and contributes to the progression of lung adenocarcinoma.

Aim: To document the expression and function of RNF126 in lung adenocarcinoma (LAD). Materials & methods: A total of 102 LAD patients were enrolled in this retrospective study. The mRNA and protein levels of RNF126 were tested via RT-qPCR and immunohistochemical staining, respectively. Univariate and multivariate analyses were conducted to exploring the clinical significance of RNF126 in the prognosis. Knockdown and overexpression strategies were used to validate the tumor-related roles of RNF126 both in vitro and in vivo. Results: RNF126 was highly expressed and was an independent predictor of a poor prognosis for LAD patients. We also revealed that RNF126 knockdown suppressed proliferation of LAD cells and xenografts. Conclusion: RNF126 is a potential survival predictor and therapeutic target for LAD.
