Summary
Snake venom toxins show promise as anticancer agents, exhibiting cytotoxicity and inhibiting tumor growth. Further research is needed for developing effective snake venom toxin-based cancer drugs.
Area of Science:
- Biochemistry
- Pharmacology
- Toxicology
Background:
- Snake venom is a complex mixture of protein and peptide toxins.
- These toxins target various physiological systems, causing pathologies.
- Existing cancer treatments have limitations, necessitating novel therapeutic strategies.
Purpose of the Study:
- To review the potential of snake venom toxins as anticancer agents.
- To explore specific toxins like phospholipase A2, L-amino acid oxidase, C-type lectin, and disintegrin.
- To compare their efficacy against cancer cell lines and animal tumor models versus normal cells.
Main Methods:
- Review of existing literature on snake venom toxins and their anticancer properties.
- Analysis of studies involving crude snake venoms and purified toxins.
- Evaluation of in vitro and in vivo preclinical data.
Main Results:
- Snake venom toxins demonstrate anti-tumor activities, including cytotoxicity and apoptosis induction.
- These toxins can inhibit cancer cell cycle progression, metastasis, and angiogenesis.
- Specific toxins like phospholipase A2, L-amino acid oxidase, C-type lectin, and disintegrin show significant anti-cancer potential.
Conclusions:
- Snake venom toxins represent a promising source for novel anticancer drug development.
- Multidisciplinary approaches are crucial for advancing preclinical and clinical studies.
- Enhancing bioavailability and targeted delivery are key for developing effective snake venom toxin-based cancer therapies.

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

190
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates...

Antidotes are medicinal substances used to counteract the harmful effects of toxins or drugs in the body. They function in various ways, each uniquely designed to combat specific toxic compounds.
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
An example of an antidote is atropine, which counteracts the detrimental effects of cholinesterase inhibitors. It achieves this by deactivating muscarinic receptors,...

Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.
