Mini Reviews in Medicinal Chemistry
|July 24, 2015
Summary
Rifaximin, a poorly absorbed antibiotic, effectively targets gut bacteria due to its unique solubility. Further research is needed to monitor resistance and understand its impact on gut flora during long-term use.
Area of Science:
- Pharmacology
- Gastroenterology
- Microbiology
Background:
- Rifaximin is a poorly absorbed rifamycin antibiotic with distinct pharmacokinetic properties.
- Its bile solubility ensures high activity in the small intestine, while low water solubility targets colon bacteria.
Purpose of the Study:
- To review the pharmacokinetic properties of rifaximin.
- To highlight its anti-inflammatory effects on gut mucosa.
- To discuss its therapeutic applications and the need for further research.
Main Methods:
- Literature review of rifaximin's properties and applications.
- Analysis of pharmacokinetic data related to absorption and solubility.
- Examination of clinical uses and potential long-term effects.
Main Results:
- Rifaximin exhibits targeted activity in the small bowel and colon based on its solubility.
- The drug possesses anti-inflammatory and gut mucosal stabilization properties.
- It is utilized for hepatic encephalopathy and irritable bowel syndrome.
Conclusions:
- Rifaximin's unique properties make it effective for specific gastrointestinal conditions.
- Long-term monitoring for bacterial resistance and efficacy is crucial.
- Further studies on intestinal flora changes and health implications are warranted.

Bacterial pathogens depend on precise and efficient DNA replication to sustain infection. Two type II topoisomerases—DNA gyrase and topoisomerase IV—are critical to this process, as they resolve DNA supercoiling and unlink chromosomes during replication. Fluoroquinolones, synthetic derivatives of quinolones, exploit this mechanism by stabilizing the transient DNA–enzyme cleavage complex, preventing strand religation, and causing lethal double-strand breaks. These...

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...

Aminoglycosides constitute a highly potent class of bactericidal antibiotics that exert their antimicrobial effects by targeting the bacterial ribosome, specifically disrupting protein synthesis. These polycationic molecules consist of amino-modified sugars linked via glycosidic bonds to an aminocyclitol core such as 2-deoxystreptamine or streptamine. Their strong positive charges facilitate tight binding to the negatively charged phosphate backbone of ribosomal RNA (rRNA), primarily at the 16S...

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

01:27Combined Effects of Drugs: Synergism
7.6K
Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.

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...
