Naturally derived chemical compounds are the foundation of much of our pharmacopeia, especially in antiproliferative and anti-infective drug classes. Here, we report that a naturally derived molecule called carmaphycin B is a potent inhibitor against both the asexual and sexual blood stages of malaria infection. Using a combination of in silico molecular docking and in vitro directed evolution ...
Among the known antimalarial drugs, chloroquine (CQ) and other 4-aminoquinolines have shown high potency and good bioavailability. Yet complications associated with drug resistance necessitate the discovery of effective new antimalarial agents. ADMET prediction studies were employed to evaluate a library of new molecules based on the 4-aminoquinolone-related structure of CQ. Extensive in vitro ...
Scrophularia umbrosa is a medicinal plant used as a traditional herb. This study was designed to investigate the phytochemical analysis of methanol (MeOH), DCM, and n-Hexane extracts of rhizome as well as total phenol and total flavonoid contents (TPC and TFC). In-vitro β-hematin formation assay and DPPH method were applied for analyzing antimalarial and free-radical scavenging activities of th...
Malaria is an acute and chronic disease caused by obligate intracellular protozoan parasites of the genus plasmodium, transmitted through the bite of female anopheles mosquitoes. According to the World Health Organization (WHO) report, currently malaria transmits in 104 countries and due to a failure in the fight against this disease, their control and elimination is difficult. The parasite res...
Malaria is a neglected tropical disease that still demands serious efforts to tackle successfully, including the need for new antimalarial lead compounds combat drug-resistant Plasmodium. Intensive phytochemical and pharmacological investigation into Indonesian medicinal plants Swietenia mahagoni Pluchea indica successfully revealed 5 constituents. Antimalarial bioassays indicated 34,5-tri- O-c...
BACKGROUND Endophytic fungi, present mainly in the Ascomycota and Basidiomycota phyla, are associated with different plants and represent important producers of bioactive natural products. Brazil has a rich biodiversity of plant species, including those reported as being endemic. Among the endemic Brazilian plant species, Vellozia gigantea (Velloziaceae) is threatened by extinction and is a pro...
Sir, At the turn of the nineteenth century, Ehrlich focused on the selective staining of malaria-infected cells over noninfected cells, with methylene blue and acridine orange. On reviewing this information, two simple questions arose: why do these compounds selectively target parasite infected cells and can this information be used against the parasite? We propose the following: methylene blue...
Malaria is responsible for more deaths around the world than any other parasitic disease. Due to the emergence of strains that are resistant to the current chemotherapeutic antimalarial arsenal, the search for new antimalarial drugs remains urgent though hampered by a lack of knowledge regarding the molecular mechanisms of artemisinin resistance. Semisynthetic compounds derived from diterpenes ...
The polyketide macrolactone FK506 inhibits the growth of Plasmodium falciparum in culture and the enzymatic (peptidyl-prolyl cis-trans isomerase [PPIase]) and chaperone activities of a recently identified P. falciparum FK506-binding protein (PfFKBP35). However, the potent immunosuppressive properties of FK506 exclude it from consideration as an antimalarial drug. We describe the antimalarial ac...
