Cinnamate-4-hydroxylase (C4H) converts trans-cinnamic acid (CA) to p-coumaric acid (COA) in the phenylpropanoid/lignin biosynthesis pathway. Earlier we reported increased expression of AaCYP71AV1 (an important gene of artemisinin biosynthesis pathway) caused by CA treatment in Artemisia annua. Hence, AaC4H gene was identified, cloned, characterized and silenced in A. annua with the assumption t...
Artemisinin drugs are of utmost importance in the treatment of malaria, because they represent the sole class of therapeutically used antimalarial drugs to which malaria parasites have not yet developed resistance. The major disadvantage of these medicines is the comparatively high recrudescence rate, which has been attributed to the remarkable decrease of artemisinin plasma concentrations duri...
BACKGROUND Rectal administration of artemisinin derivatives has potential for early treatment for severe malaria in remote settings where injectable antimalarial therapy may not be feasible. Preparations available include artesunate, artemisinin, artemether and dihydroartemisinin. However each may have different pharmacokinetic properties and more information is needed to determine optimal dose...
In the developing world, multi-drug resistant malaria caused by the parasite Plasmodium falciparum is an epidemic that claims the lives of 1-3 million people per year. Artemisinin, a naturally occurring small molecule that has seen little resistance from malarial parasites, is a valuable weapon in the fight against this disease. Several easily accessible artemisinin derivatives, including artes...
Age-related macular degeneration is a multifactorial disease affecting the posterior segment of eye and characterized by aberrant nascent blood vessels that leak fluid. It ends with vision loss. In present study, artemisinin which poorly water-soluble has potent anti-angiogenic anti-inflammatory properties was formulated into nanomicelles for its ocular application activity using CAM assay. Art...
In this data article, we described the synthetic routes to four biotinylated probes (2, 3, 4, and 5) of artemisinin and the associated experimental procedures. We also provided the physical data for the synthesized compounds. These synthesized biotinylated probes of artemisinin are useful molecular tools for the affinity-labeling study of target receptor proteins of artemisinin in tropical path...
Artemisinin, a sesquiterpene lactone produced by Artemisia annua glandular secretory trichomes, is the active ingredient in the most effective treatment for malaria currently available. We identified a mutation that disrupts the amorpha-4,11-diene C-12 oxidase (CYP71AV1) enzyme, responsible for a series of oxidation reactions in the artemisinin biosynthetic pathway. Detailed metabolic studies o...
Malaria is a protozoan disease transmitted by the bite of the Anopheles mosquito. Among five species that can infect humans, Plasmodium falciparum is responsible for the most severe human malaria. Resistance of P. falciparum to chloroquine and pyrimethamine/sulfadoxine, conventionally used antimalarial drugs, is already widely distributed in many endemic areas. As a result, artemisinin-based co...
Artemisinin is a natural sesquiterpene lactone obtained from the Artemisia annua herb. It is widely used for the treatment of malaria. In this article, we have reviewed the role of artemisinin in controlling malaria, spread of resistance to artemisinin and the different methods used for its large scale production. The highest amount of artemisinin gene expression in tobacco leaf chloroplast lea...
Until very recently, artemisinin and its derivatives were the only commercially available antimalarial drugs for which there was no reported parasite resistance. Artemisinin combination therapies (ACTs) are currently relied upon for effective malaria treatment in most regions of the world in which the disease is endemic, and their continuing efficacy is crucial if control and elimination progra...
