Insights

Cancer drugs show promise for treating parasitic diseases due to cell similarities. This review explores using anticancer agents to discover new antiparasitic therapies for major human parasitic infections.

Area of Science:

  • Parasitology
  • Oncology
  • Drug Discovery

Background:

  • Parasitic diseases pose significant global health challenges.
  • Cancer cells and parasites share biological characteristics.
  • Existing anticancer drugs may offer novel antiparasitic treatments.

Purpose of the Study:

  • To review the potential of anticancer agents in treating human parasitic diseases.
  • To identify promising anticancer drugs with antiparasitic activity.
  • To explore a novel drug discovery strategy by repurposing cancer therapeutics.

Main Methods:

  • Literature review of existing anticancer agents.
  • Analysis of shared cellular pathways between cancer and parasites.
  • Evaluation of preclinical and clinical data on repurposed drugs.

Main Results:

  • Several classes of anticancer agents demonstrate antiparasitic effects.
  • Specific molecular targets are conserved between cancer cells and parasites.
  • Repurposing anticancer drugs offers a viable strategy for neglected tropical diseases.

Conclusions:

  • Anticancer agents represent a promising source for novel antiparasitic drug discovery.
  • Targeting conserved pathways offers a translatable approach.
  • Further research is warranted to develop these agents for clinical use against parasitic infections.

Anthelminthic Agents01:15

Anthelminthic Agents

Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...

Antiprotozoal Agents

Leishmaniasis is a widespread parasitic disease caused by several Leishmania species. It affects millions of people each year and remains a major public health problem in endemic regions. First-line treatment relies on pentavalent antimonials, including meglumine antimoniate and sodium stibogluconate. Even so, how these drugs work has not been fully clear, especially their interaction with parasite-specific biochemical pathways. One key target is trypanothione reductase (TR), an enzyme that...

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.
Phenothiazines, such as prochlorperazine...

Targeted 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.
There are several types of targeted therapies against specific...

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

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 these...
