Introduction: Apigeninidin chloride (APi) is a form of 3-deoxyanthrocyanidins (3-DAs) abundantly produced by the red plant. It has been previously reported to be effective against () tachyzoites grown with less cytotoxic effect. However, its possible mechanism(s) of action has not been elucidated.

Quercetin (QUE) is a natural polyphenol known to have numerous pharmacological properties against infectious and non-infectious diseases. Azithromycin (AZ) is an antibiotic that belongs to the azalide class of antimicrobials and an antiparasitic that is known to be effective in combination with clindamycin against pyrimethamine/sulfadiazine-resistant Toxoplasma gondii tachyzoites in clinical settings. Both compounds are known to target protein synthesis and have anti-inflammatory properties.

There is an unmet need to unearth alternative treatment options for malaria, wherein this quest is more pressing in recent times due to high morbidity and mortality data arising mostly from the endemic countries coupled with partial diversion of attention from the disease in view of the SARS-Cov-2 pandemic. Available therapeutic options for malaria have been severely threatened with the emergence of resistance to almost all the antimalarial drugs by the parasite in humans, which is a worrying situation. Artemisinin combination therapies (ACT) that have so far been the mainstay of malaria have encountered resistance by malaria parasite in South East Asia, which is regarded as a notorious ground zero for the emergence of resistance to antimalarial drugs.

is a zoonotic parasite that infects the brain of humans and causes cerebral toxoplasmosis. The recommended drugs for the treatment or prophylaxis of toxoplasmosis are pyrimethamine (PY) and sulfadiazine (SZ), which have serious side effects. Other drugs available for toxoplasmosis are poorly tolerated.

() is one of the major food and waterborne bacteria that causes several health outbreaks in the world. Although there are few antibiotics against this bacterium, some of these drugs are challenged with resistance and toxicity. To mitigate this challenge, our group explored the ethnomedicinal/herbalism knowledge about a certain spice used in Northern Ghana in West Africa against bacterial and viral infection.

Apigenin-7-O-glucoside, a flavonoid glucoside known to inhibit cancer cell growth, fungi growth, both intra and extracellular reactive oxygen species generation, causing cell arrest and damage to the plasma membrane, was tested alone or in combination with a dihydrofolate inhibitor (pyrimethamine) against () growth. The anti- activity was carried out using a high throughput antiparasitic drug screening cell-based assay known as 2-(2-methoxy-4-nitrophenyl)-3-(4-nitrophenyl)-5-(2,4-disulfophenyl)-2H tetrazolium, monosodium salt (WST-8) and fluorescence plate reader. The 50% effective concentration inhibition and 95% confidence interval values for individual and combination treatments against were 0.

Article Synopsis
  • Toxoplasma gondii infects about a third of the global population, and existing treatments have limitations like ineffectiveness and side effects, highlighting the need for new drugs.
  • Research tested oil-like crude extracts from Sorghum bicolor, traditionally used in Africa for treating infections, for their anti-Toxoplasma activity.
  • The study found that these extracts significantly inhibited T. gondii growth with minimal toxicity to human cells, suggesting potential for developing new treatments or nutraceuticals.

Kidney cancer ranks among the top 10 cancers in the United States. Although it affects both male and female populations, it is more common in males. The prevalence rate of renal cell carcinoma (RCC), which represents about 85% of kidney cancers, has been increasing gradually in many developed countries.

Article Synopsis
  • Toxoplasma gondii is a widespread parasite affecting a significant portion of the global population, particularly those with weakened immune systems.
  • Researchers tested five synthetic 3-deoxyanthocyaninidin compounds for their effectiveness against T. gondii and found strong inhibitory effects with minimal harm to human cells.
  • The study suggests that these compounds could be promising candidates for treating human toxoplasmosis due to their antiparasitic properties.

Toxoplasmosis is one of the most neglected zoonotic foodborne parasitic diseases that cause public health and socioeconomic concern worldwide. The current drugs used for the treatment of toxoplasmosis have been identified to have clinical limitations. Hence, new drugs are urgently needed to eradicate T.

The phosphobase methylation pathway, in which phosphoethanolamine N-methyltransferases (PMTs) successively catalyze the methylation of phosphoethanolamine to phosphocholine, is essential in the free-living nematode Caenorhabditis elegans. Two PMT-encoding genes (HcPMT1 and HcPMT2) cloned from Haemonchus contortus have been shown, by in vitro assays, to possess enzymatic characteristics similar to those of C. elegans PMTs, but their physiological significance in H.

Article Synopsis
  • The study examined the effectiveness of dried red leaf extracts from Sorghum bicolor against Toxoplasma gondii tachyzoites using bioassay-guided fractionation methods.
  • The extracts contained various 3-deoxyanthocyanidin compounds, identified through mass spectrometry, with significant antiparasitic activity.
  • The findings revealed that these extracts had lower inhibitory concentration (IC50) values against T. gondii than their cytotoxic effects on mammalian cells, suggesting potential for their use as antiparasitic agents.
