Downstream Processing and Anticancer Evaluation of Bioactive Compounds from Allium przewalskianum against Colorectal Cancer

Abstract

Cancer is a big problem worldwide, causing lots of sickness and death every year. Even though we have made progress in treating it, the usual treatments like chemotherapy can make people very sick, and sometimes the cancer becomes resistant to the drugs. As more people survive cancer, we need to think about the lasting effects of the treatment. Natural remedies made from plants, known for fighting inflammation and cancer, seem like they could help alongside regular treatments. Allium przewalskianum, found in the Himalayas, has been used in traditional medicine and has helpful compounds like other Allium plants known for their healing properties. This study aimed to see if Allium przewalskianum can help treat colorectal cancer (CRC), how it works and to examine how it affects the cancer cells' structure, changes in the levels of ROS, TNF-α, NF-Κb, MMP and the pathway followed for the apoptosis of cells. It also aimed to check the molecules that can help prepare nanoparticles which can be effectively used in the treatment of CRC. Methods: Phytochemical analysis involves isolating and identifying bioactive compounds using chromatographic techniques and spectroscopic methods. With a comprehensive approach, the study conducted a series of in vitro assays and chemical analyses. Cancer cell viability assays were conducted utilizing the MTT method, while morphological changes were visualized through immunofluorescence microscopy. ROS levels were quantified using DCFDA, and mitochondrial membrane potential was also assessed. Cell cycle progression and apoptosis were evaluated through flow cytometry, with caspase activity assays elucidating apoptotic pathways. Furthermore, green synthesis of nanoparticles was carried out, followed by their characterization and assessment of antiproliferative activity against CRC cells. In another application, six chemotherapeutic drugs and bioactive were incubated with Escherichia coli and analyzed for effects on the anticancerous activity on HCT116 cells. Results: The study found that using different xix amounts of Allium przewalskianum plant extract led to the death of colorectal cancer cells. The chloroform fraction worked best against HCT116 cells alongwith the pathway followed for the death of cells was analyzed. A particular compound was identified from the plant that helped to slow down the cancer cells in a few different ways, like messing up their energy factories, mitochondria, making harmful molecules, like ROS and altering the expression of COX 2, TNF-α and NF κB. The purified bioactive was used to make nanoparticles from the plant that were effective in slowing down the cancer cells. For the better understanding and clarity on real life scenarios, the study also focused on the altered efficacy of chemotherapeutic drugs in the presence of Escherichia coli. Amongst all six drugs, the effectiveness of Cytarabine increased against colorectal cancer which indicates the synergistic effect of drug and microbe. Using natural products like this could be essential for making new cancer treatments. However, more studies are needed to understand exactly how Allium przewalskianum works and ensure it's safe and effectiveness for people. This study is a step forward in using natural remedies to fight cancer and suggests that the green nanoparticles could also be useful in treating cancer.is a big problem worldwide, causing lots of sickness and death every year.

Natural remedies made from plants, known for fighting inflammation and cancer, seem like they could help alongside regular treatments. Many plants, like those in the Bignoniaceae, Caricaceae, and Rutaceae families, have shown promise in fighting cancer.
