Nimbolide: A Potential Phytochemical Agent in Multimodal Pancreatic Cancer Therapies.

A significant contributor to cancer-related death, pancreatic cancer (PC) has a terrible prognosis in general that has not altered over many years. Currently, it is extremely difficult to prevent disease or discover it early enough to initiate treatment. PC is a challenging malignancy to treat, and several major impediments significantly impact the effectiveness of its treatment. These obstacles primarily include chemoresistance, drug toxicity, and limited drug bioavailability. Phytochemicals can be used as an alternative to chemotherapeutic drugs, or they can augment the anticancer properties of the chemotherapeutic agents. Nimbolide (NL) is a prominent limonoid compound found in Azadirachta indica, and has garnered substantial attention as a phytochemical with anticancer potential. It has powerful antiproliferative effects on a variety of cancer cell lines and is effective as a chemotherapeutic in preclinical studies. The primary modes of action of NL include suppression of metastasis and angiogenesis, activation of apoptosis, anti-proliferation, and control of enzymes that metabolize carcinogens. Despite numerous pharmacodynamic (PD) investigations, NL is still in the early stages of the drug development process because no comprehensive pharmacokinetic studies or long-term toxicity studies. Preclinical and toxicological assessments should be conducted to establish an appropriate dosage range, ensuring the safety of NL for its application in initial human clinical trials. This review endeavors to provide a comprehensive summary of the current developmental stage of NL along with nanoparticles as a principal candidate for therapeutic purposes in PC.
