Abstract
Malaria is a major parasitic disease and is responsible for almost one million deaths each year in Africa. There is an urgent need to discover new active compounds. Nature and particularly plants are a potential source of new antimalarial drugs since they contain a quantity of metabolites with a great variety of structures and pharmacological activities. This review covers the compounds with antiplasmodial activity isolated from plants which have been published during 2009 organized according to their phytochemical classes. Details are given for substances with IC50 values ≤ 11 µM. Sixty-seven references are identified.
#Introduction
There were an estimated 247 million malaria cases among 3.3 billion people at risk in 2006, causing nearly a million deaths, mostly of children under 5 years (WHO, 2008). This disease, transmitted by an Anopheles mosquito, is caused by Plasmodium species. The parasite is now resistant to a number of antimalarials but plants can offer new metabolites with an original mode of action such as artemisinin from Artemisia annua which can be active on resistant strains. In this review, all antiplasmodial metabolites new or already known and isolated from plants to treat malaria and published in 2009 are described and organised according to their phytochemical classes. All the activities were determined in vitro on Plasmodium falciparum strains unless specified and bioguided fractionation was also based on this antimalarial test. Activities were assessed on different strains among which some are chloroquine sensitive (NF54, 3D7, D6, F32, D10, Ghana, TM4), chloroquine resistant (FcB1, W2, FCM29, Dd2, FCR-3) and/or multidrug resistant (K1) strains, to find effective compounds on resistant malaria. We considered that those having an IC50 ≤ 11 µM may have some interest for further development, while those with a lower activity were less interesting. That is why we only give structures for these promising compounds, the others are cited in tables. Compounds tested in vivo are also cited. We also analysed the phytochemical classes of these metabolites published in 2009 and the families of plant from which they were isolated and compared these data with those of compounds published from 2005 to 2008. Other reviews already exist for compounds published before 2005 [1], [2], [3], [4], [5], [6], [7], or before 2009 [8], [9], [10].

The average parasitemia of 32.8 % in the control red blood cells was decreased significantly to 12.1 % by the administration of 0.8 mg/kg/day of the compound for four days [51].
#Discussion and Conclusions
In traditional medicine, traditional healers use plants for the treatment of malaria or several symptoms of the disease. This review focusing on publications of 2009 shows that some promising new antimalarial compounds can be isolated by the ethnopharmacological and bioguided fractionation approaches. Various extracts of plants were fractionated to obtain 146 compounds which were evaluated for antimalarial activity in vitro. Among them, 41 possessed low (11 < IC50 < 50 µM), 65 moderate (2 < IC50 < 11 µM) and 31 promising (IC50 < 2 µM) activity in vitro against various strains of Plasmodium falciparum which is responsible for the most severe form of malaria. The activity of some of these compounds was tested against various cell lines, normal or cancer cells, but only a few of them for their in vivo antimalarial activity. Nevertheless, in these cases, the promising in vitro activities could be confirmed by in vivo tests. Among them, a phenolic compound: 6-(8′Z-pentadecenyl)-salicylic acid, a sesquiterpene lactone: 11(13)-dehydroivaxillin, a tryptophane derivative: prosopilosine, and a linear polyacetylenic diol seem promising.
Moreover, ellagic acid already isolated and tested in vitro before 2009 with an IC50 of 0.5 µM on D6 and 0.3 µM on W2 with no cytotoxicity, displayed interesting antimalarial efficacy in vivo with a parasitemia reduction of 50 % at 1.0 mg/kg/day by the intraperitoneal route. This compound could be an interesting candidate for further development [52], [53].
Among the compounds we reviewed, only a few of them exhibited a good activity and should be considered as lead compounds for further investigations ([Table 1]). In 2009, most of the highly active compounds were found in the alkaloid and terpene chemical classes, which was also the case in 2005–2008 ([Fig. 14]). The same trend was observed when considering families from which active compounds were isolated ([Fig. 15]). Most active alkaloids published in 2009 were isolated from the Leguminosae and Rutaceae families [10]. In our previous review, Leguminosae was also identified as a family allowing isolation of a significant number of active alkaloids, while Rutaceae was not found to be particulary interesting although it is a family whose activity is often due to the presence of alkaloids [6].

The more active triterpenes were obtained from Simaroubaceae which seem to have been well studied in 2009 and were not identified as an interesting family in 2005–2008. However, other reviews confirmed that the active antimalarial molecules of the Simaroubaceae are mainly quassinoids [6], [9]. Quassinoids often displayed anticancer activity but the antimalarial activity does not seem to be correlated with the cytotoxicity [54].
When considering highly active compounds and families from which they were isolated and comparing with the results of 2005–2008, we observed that in 2009 no highly active diterpene was isolated, although this class was pointed out to be very interesting in 2005–2008. The same is observed with the Caesalpinaceae family from which they were isolated. This may be explained by the fact that one team focused in 2005–2008 on diterpenes from Caesalpinaceae leading to Kalauni et al. [55] and Linn et al. [56].
Three of the most active sesquiterpenes are lactones and were obtained from a plant of the Asteraceae family as it was the case for the “famous” artemisinin.
Among families from which most highly active compounds were isolated in 2005–2008, Menispermaceae and Asphodelaceae are not represented in 2009 while from Moraceae, only one interesting flavonoid (artopeden A) was isolated.
These observations and comparisons show that it is often difficult to assess general rules concerning interesting classes of compounds or interesting families as it may depend highly on the activity of specific research groups. Nevertheless, we can indicate that during 2009, alkaloids from the Leguminosae and Rutaceae families, quassinoids from Simaroubaceae and well-known sesquiterpene lactones from Asteraceae were described as interesting antimalarial compounds with original structures which could be considered as lead compounds for new drugs against resistant malaria.
