Background: Worldwide, cancer is claimed a major public health problem and is another leading cause of death after ischemic heart diseases. Currently, the nutraceuticals and their biologically active phytoconstituents have received immense attention for the prevention and treatment of cancer due to origin authenticity, natural compatibility, and least toxicity. Objective: The contemporary research venture aimed to investigate the anticancer potential of polar fractions of the Chrozophora tinctoria plant. The plant was selected due to its wide-ranging therapeutic potential having its role in wound healing, anti-inflammatory, antimicrobial, antineoplastic as well as antioxidant activities. Methods: The aerial part of the C. tinctoria was extracted with methanol and then fractionated with liquid-liquid extraction by utilizing water, butanol, ethyl acetate, chloroform, and n-hexane. In addition to total phenolic, the flavonoid contents were also determined. Phytochemical analysis was performed and maximum phenolic and flavonoid contents were obtained in chloroform and ethyl acetate fractions. Results: The obtained fractions were assessed for potential anticancer agents by utilizing HeLa and MCF-7 cells. The most active fractions from initial anticancer screening were further investigated microscopically to determine apoptosis, production of reactive oxygen species (ROS) as well as cell cycle arrest (flow cytometry). Interestingly, the maximum cytotoxic activity in cancer cells was observed by ethyl acetate and chloroform fraction. Conclusion: It is concluded that ethyl acetate and chloroform fractions showed the most promising anticancer activity and would be a new treatment option for the most common cancer in females.

Background: Plants are a vital source of natural drugs as the traditional use of plants as therapeutic agents for a variety of ailments has been traced back thousands of years. The utilization of Heliotropium calcareum has been evident since ancient times for treating various disease states like inflammation associated with gout and rheumatism, poisonous bites, and other skin disorders. The current research work was carried out to determine the phytochemistry and biological activities of the crude methanolic extract obtained through maceration from the aerial parts of Heliotropium calcareum. Methods: The plant was collected from district Bhakkar, Punjab, Pakistan. Maximum phenolic (74.5 μg GAE/mg) and flavonoid contents (58.99 μg QE/mg) were observed in ethyl acetate fraction. Significant antioxidant potential was observed in ethyl acetate fraction with the highest free radical hunting activity of 92.6 ± 6.7 μM. Results: Cytotoxicity assay using MTT dye was performed where non-polar (n-hexane) and polar (ethyl acetate) fractions displayed excellent cytotoxicity against HeLa cells (IC50 = 79.95 ± 3.718 & 164 ± 4 μg/mL, respectively). Furthermore, the above fractions showed momentous results in cell cycle analysis and promising proapoptotic effect against cervical (HeLa) cancer cell lines. An nhexane and ethyl acetate fraction were selected for cell cycle analysis to determine the quantitative measurement of the degree of apoptosis. According to the results given below in the figure, the cervical (HeLa) cancer cells were treated with n-hexane and ethyl acetate fractions at various concentrations. An increase in the cell population at G0/G1 phase and a decrease in the S-phase population concerning untreated cells suggested the G0/G1 phase arrest in n-hexane and ethyl acetate fractions treated HeLa cells. Conclusion: Taken together, n-hexane and ethyl acetate fractions were found to be the most promising and active elements of H. calcareum and may be utilized to explore their cytotoxic effects further in the animal model.

Background: The use of antibiotics has compromised due to the appearance of multidrug- resistant strains and decreased susceptibility of strains to antibiotics. Antibiotic resistance has become a worldwide threat as well as Helicobacter pylori induced gastric cancer is a major problem nowadays. Therefore, it is the need of time to synthesize potent anti-urease motifs. Introduction: Schiff bases represent a large class of biologically active compounds that exhibited a broad spectrum of biological activities. Amikacin is an important drug used against multidrugresistant species of microbes. Therefore, imine derivatives of amikacin may help to reduce the resistance of microbes and to treat the Helicobacter pylori induced stomach problems by inhibiting the Helicobacter Pylori Urease enzyme. Methods: Schiff bases of amikacin were synthesized and screened for in-vitro antibacterial assay performed by well diffusion method against Bacillus megaterium (Bm), Bacillus subtilis (Bs), Stenotrophomonas maltophilia (Sm), Staphylococcus aureus (Sa), Micrococcus luteus (Ml), Serratia marcescens (S. mar), Escherichia coli (E. coli) and anti-urease activity was performed by Indophenol method. Structures confirmed by IR, 1HNMR and 13CNMR spectroscopy. Results: Compounds showed varying degrees of antibacterial effects. Schiff bases A2 and A8 exhibited potent urease inhibition activity with Ki values 0.2754 and 0.2908 μM, respectively and their binding affinity was calculated as greater than the standard drug. Conclusion: Derivatives of amikacin with aromatic rings were more active antibacterials than those with an aliphatic side chain. The potent anti-urease activity has been recorded for compounds A2 and A8. Therefore, they may serve as lead compounds in the discovery of Helicobacter pylori Urease inhibitors.
