Abstract

Insights

New therapeutics for cryptosporidiosis are advancing, with promising drug candidates identified through various discovery approaches. Further research is needed to move these treatments to clinical trials and combat drug resistance.

Area of Science:

  • * Parasitology and Tropical Medicine
  • * Drug Discovery and Development

Background:

  • * Cryptosporidiosis, caused by the parasite Cryptosporidium, leads to severe health issues including diarrhea, malnutrition, and developmental problems in children.
  • * It disproportionately affects children in low-resource settings, contributing to long-term health deficits and vaccine failure.

Purpose of the Study:

  • * To review recent advancements in the development of novel therapeutics for cryptosporidiosis.
  • * To identify promising drug candidates and outline potential pathways for clinical development and regulatory approval.

Main Methods:

  • * Exploration of various drug discovery strategies, including target-based and phenotypic screening.
  • * Evaluation of repurposed drugs and novel chemical entities against Cryptosporidium.
  • * Assessment of lead compound activity in preclinical models and emerging pharmacokinetic data.

Main Results:

  • * Identification of several promising lead compounds, including inhibitors of specific synthetases and kinases.
  • * Testing of clofazimine in HIV patients with cryptosporidiosis showed ineffectiveness.
  • * Emerging understanding of the link between pharmacokinetic properties and in vivo efficacy.

Conclusions:

  • * Several compounds show potent activity and favorable safety profiles in preclinical studies.
  • * Advancing at least one candidate to clinical proof-of-concept is crucial.
  • * Developing combination therapies is recommended due to the risk of drug resistance.

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Drugs for Treatment of Diarrhea-Predominant IBS01:17

Drugs for Treatment of Diarrhea-Predominant IBS

Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents

Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...

Drugs Affecting GI Tract Motility: Adsorbents as Antidiarrheal Agents

Diarrhea is characterized by the occurrence of frequent, watery bowel movements. Various factors can trigger diarrhea, including viral or bacterial infections, foodborne illnesses, side effects from certain medications, and underlying digestive disorders. If not adequately managed, diarrhea can lead to complications such as dehydration, electrolyte imbalances, and nutrient deficiencies. Severe diarrhea can lead to significant weight loss, malnutrition, and weakened immune function.

Drugs for Treatment of Ulcerative Colitis in IBD01:29

Drugs for Treatment of Ulcerative Colitis in IBD

Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Drugs for Treatment of Constipation-Predominant IBS01:21

Drugs for Treatment of Constipation-Predominant IBS

Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...
