Treatment of plasmodium chabaudi parasites with curcumin in combination with antimalarial drugs: Drug interactions and implications on the ubiquitin/proteasome system

  • Autores: Do Rosário V, Gazarini ML, Lindeza A, Lopes D, Machado M, Neto Z
  • Ano de Publicação: 2013

Antimalarial drug resistance remains a major obstacle in malaria control. Evidence from Southeast Asia shows that resistance to artemisinin combination therapy (ACT) is inevitable. Ethnopharmacological studies have confirmed the efficacy of curcumin against Plasmodium spp.

The isolation of bioactive compounds from medicinal plants, based on traditional use or ethnomedical data, is a highly promising potential approach for identifying new and effective antimalarial drug candidates.

Plasmodium chabaudi chabaudi malaria parasites can develop stable resistance to atovaquone with a mutation in the cytochrome b gene

  • Autores: Afonso A, Alves AC, Castro H, Lopes D, Neto Z, Rosário VD, Tomás AM
  • Journal: Malaria Journal
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Plasmodium+chabaudi+chabaudi+malaria+parasites+can+develop+stable+resistance+to+atovaquone+with+a+mutation+in+the+cytochrome+b+gene

BACKGROUND:
Plasmodium falciparum, has developed resistance to many of the drugs in use. The recommended treatment policy is now to use drug combinations. The atovaquone-proguanil (AP) drug combination, is one of the treatment and prophylaxis options. Atovaquone (ATQ) exerts its action by inhibiting plasmodial mitochondria electron transport at the level of the cytochrome bc1 complex.

BACKGROUND:
Malaria is the major cause of morbidity and mortality in Angola. The most vulnerable groups to Plasmodium falciparum infection are pregnant women and children under five years of age.
