One of the key concerns in public health is food security in the food sector. Due to the large amounts of potentially hazardous metals in wastewater, this practice may pose serious environmental and health risks to neighboring residents. In this study, the health effects of heavy metals in vegetables irrigated with wastewater were studied. The findings indicated a massive accumulation of heavy metals in wastewater-irrigated soil and vegetables collected from Bhakkar, Pakistan. The current study looked at the effects of wastewater irrigation on metal buildup in the soil–plant continuum and the health hazards that come with it (Cd, Co, Ni, Mn, Pb, and Fe). Heavy metal concentrations in vegetables cultivated on soil irrigated with untreated wastewater were not significantly lower (p ≥ 0.05) than in vegetables grown on wastewater-irrigated soil and were below the World Health Organization’s recommended limits. A considerable amount of the selected hazardous metals was also swallowed by adults and children who consumed these vegetables, according to the research. On soil that had received wastewater irrigation, Ni and Mn were substantially different at p ≥ 0.001 levels. Pb, Ni, and Cd had health risk scores higher than the ones in all ingested vegetables, while Mn had a health risk score greater than the ones in turnips, carrots, and lettuce. The results also showed that both adults and children who consumed these vegetables absorbed a significant amount of the chosen toxic metals. Pb and Cd were shown to be the most dangerous chemical compounds to human health, and everyday consumption of agricultural plants irrigated with wastewater may pose a health risk, according to the health risk criteria.

Cancer is a hard-to-treat disease with a high reoccurrence rate that affects health and lives globally. The condition has a high occurrence rate and is the second leading cause of mortality after cardiovascular disorders. Increased research and more profound knowledge of the mechanisms contributing to the disease’s onset and progression have led to drug discovery and development. Various drugs are on the market against cancer; however, the drugs face challenges of chemoresistance. The other major problem is the side effects of these drugs. Therefore, using complementary and additional medicines from natural sources is the best strategy to overcome these issues. The naturally occurring phytochemicals are a vast source of novel drugs against various ailments. The modes of action by which phytochemicals show their anti-cancer effects can be the induction of apoptosis, the onset of cell cycle arrest, kinase inhibition, and the blocking of carcinogens. This review aims to describe different phytochemicals, their classification, the role of phytochemicals as anti-cancer agents, the mode of action of phytochemicals, and their role in various types of cancer.

Aims: The study aims to synthesize hybrid molecules containing pyrazole and aryldiazenyl/arylhydrazono fragments with promising anticancer activity. Background: The clinical effectiveness of anticancer drugs is limited by their adverse side effects and patient resistance. Therefore, the development of safer classes of drugs through rational drug design is imperative. Objective: Considering the anticancer potential of the pyrazole moiety, the study was carried out with the objective of synthesizing some hybrid pyrazole derivatives with anticancer potential. Method: The anticancer potential of these pyrazolyl analogues were evaluated by sulforhodamine B assay using three cancer cell lines MCF-7, HepG2, and HCT-116. Result: HCT-116 was the most sensitive cell line against these pyrazolyl analogues. Among these newly synthesised derivatives, 1-(4-((4-bromophenyl)diazenyl)-3,5-dimethyl-1H-pyrazol-1-yl)-2-(naphthalen-2-yloxy)ethan-1-one (5e) emerged as a promising anticancer agent (IC50 3.6-24.6 μM), having a xanthine oxidase inhibitory effect (IC50 10.87 μM). To obtain further insights into the binding interactions of these molecules, molecular docking studies were also carried out. Conclusion: In summary, our findings suggest that these hybrid pyrazolyl derivatives can be considered as potential lead molecules for anticancer agents.
