Dietary compounds in cancer prevention have gained significant consideration as a viable method. Indole-3-carbinol (I3C) and 3,3′-diindolylmethane (DIM) are heterocyclic and bioactive chemicals found in cruciferous vegetables like broccoli, cauliflower, cabbage, and brussels sprouts. They are synthesized after glycolysis from the glucosinolate structure. Clinical and preclinical trials have evaluated the pharmacokinetic/pharmacodynamic, effectiveness, antioxidant, cancer-preventing (cervical dysplasia, prostate cancer, breast cancer), and anti-tumor activities of I3C and DIM involved with polyphenolic derivatives created in the digestion showing promising results. However, the exact mechanism by which they exert anti-cancer and apoptosis-inducing properties has yet to be entirely understood. Via this study, we update the existing knowledge of the state of anti-cancer investigation concerning I3C and DIM chemicals. We have also summarized; (i) the recent advancements in the use of I3C/DIM as therapeutic molecules since they represent potentially appealing anti-cancer agents, (ii) the available literature on the I3C and DIM characterization, and the challenges related to pharmacologic properties such as low solubility, and poor bioavailability, (iii) the synthesis and semi-synthetic derivatives, (iv) the mechanism of anti-tumor action in vitro/in vivo, (v) the action in cellular signaling pathways related to the regulation of apoptosis and anoikis as well as the cell cycle progression and cell proliferation such as peroxisome proliferator-activated receptor and PPARγ agonists; SR13668, Akt inhibitor, cyclins regulation, ER-dependent-independent pathways, and their current medical applications, to recognize research opportunities to potentially use these compounds instead chemotherapeutic synthetic drugs.

EhCP112 is an Entamoeba histolytica protease that together with the EhADH112 protein forms the EhCPADH complex involved in trophozoite virulence. Here, we produced the recombinant EhCP112 and studied its relationships with extracellular matrix components and with target cells. A DNA fragment containing the pro-peptide and the mature enzyme was expressed in bacteria as an active enzyme (rEhCP112), whereas the full gene containing the signal peptide, the pro-peptide and the mature enzyme expressed a non-active protein. The fragment only with the mature enzyme was not expressed. rEhCP112 purified by affinity columns digested azocasein and had a strong autoproteolytic activity. Four hours after purification the protein appeared degraded. Anti-tag antibodies, monoclonal antibodies against the EhCP112 and sera from human patients with amoebiasis recognized rEhCP112. rEhCP112 digested gelatin, collagen type I, fibronectin and haemoglobin; it destroyed MDCK cell monolayers and bound to red blood cells. The native EhCP112 was poorly expressed in a virulence-deficient mutant, and in the wild-type clone it was located in secreted vesicles, forming the EhCPADH complex. Altogether these results show that EhCP112 is a molecule able to disrupt cell monolayers and digest proteins of the extracellular matrix and haemoglobin, and it is secreted by the trophozoites.

Lithium is a therapeutic cation used to treat bipolar disorders but also has some important features as an anti-cancer agent. In this review, we provide a general overview of lithium, from its transport into cells, to its innovative administration forms, and based on genomic, transcriptomic, and proteomic data. Lithium formulations such as lithium acetoacetate (LiAcAc), lithium chloride (LiCl), lithium citrate (Li₃C₆H₅O₇), and lithium carbonate (Li₂CO₃) induce apoptosis, autophagy, and inhibition of tumor growth and also participate in the regulation of tumor proliferation, tumor invasion, and metastasis and cell cycle arrest. Moreover, lithium is synergistic with standard cancer therapies, enhancing their anti-tumor effects. In addition, lithium has a neuroprotective role in cancer patients, by improving their quality of life. Interestingly, nano-sized lithium enhances its anti-tumor activities and protects vital organs from the damage caused by lipid peroxidation during tumor development. However, these potential therapeutic activities of lithium depend on various factors, such as the nature and aggressiveness of the tumor, the type of lithium salt, and its form of administration and dosage. Since lithium has been used to treat bipolar disorder, the current study provides an overview of its role in medicine and how this has changed. This review also highlights the importance of this repurposed drug, which appears to have therapeutic cancer potential, and underlines its molecular mechanisms.

Moringa oleifera (MO) has gained recognition as a potent natural intervention for preventing and managing chronic diseases (CDs) due to its diverse phytochemical composition and pharmacological properties. Rich in antioxidants, polyphenols, flavonoids, and glucosinolates, MO exerts anti-inflammatory, anti-hyperglycemic, cardioprotective, and anti-obesity effects. These properties make it a valuable therapeutic agent for CDs, including diabetes, cardiovascular diseases, obesity, neurodegenerative disorders, and cancer. MO’s ability to modulate oxidative stress and inflammation—key drivers of CDs—highlights its significant role in disease prevention and treatment. MO enhances insulin sensitivity, regulates lipid profiles and blood pressure, reduces inflammation, and protects against oxidative damage. MO also modulates key signaling pathways involved in cancer and liver disease prevention. Studies suggest that MO extracts possess anticancer activity by modulating apoptosis, inhibiting tumor cell proliferation, and interacting with key signaling pathways, including YAP/TAZ, Nrf2-Keap1, TLR4/NF-κB, and Wnt/β-catenin. However, challenges such as variability in bioactive compounds, taste acceptability, and inconsistent clinical outcomes limit their widespread application. While preclinical studies support its efficacy, large-scale clinical trials, standardized formulations, and advanced delivery methods are needed to optimize its therapeutic potential. MO’s multifunctional applications make it a promising and sustainable solution for combating chronic diseases, especially in resource-limited settings.
