The growth and spread of resistance to all first-line antimalarial drugs used in the treatment of malaria today has caused many problems in eradicating malaria in various countries in the world. Researchers have begun to look for candidates for new antimalarial drug compounds derived from natural products that have been scientifically proven to have antimalarial activity. This is done to replace antimalarial drugs that are currently experiencing resistance. Some active compounds that have been successfully isolated from various plants, including curcumin, kaempferol, piperine, andrographolide, α-mangostin, catechin, luteolin and betulinic acid, have been scientifically tested to have antimalarial activity with different mechanisms of action.

Key words: Malaria, Antimalarial, Curcumin, Kaempferol, Piperine, Andrographolide, α-Mangostin, Catechin, Luteolin, Betulinic acid.

Background: Cerebral malaria (CM) is one of the most severe complications of Plasmodium falciparum infection and the leading cause of death from malaria in endemic areas. Natural products with antioxidant and anti-inflammatory activities have become valuable alternative therapeutic options in CM treatment. Therefore, this study aimed to investigate the neuroprotective effects of curcumin and kaempferol in experimental cerebral malaria (ECM) in mice infected with Plasmodium berghei ANKA (PbA). Methods: After PbA infection, mice were divided into 9 groups, namely Group I (negative control (NC)) with 0.5\% HPMC, Group II received chloroquine 20 mg/kg, Group III (normal) with aquadest, Groups IV, V, and VI received curcumin at doses of 20, 40, and 80 mg/kg, respectively, Groups VII, VIII, and IX received kaempferol at doses of 20, 40, and 80 mg/kg, respectively. The antimalarial activity was evaluated using Peter{\textquoteright}s four-day suppressive test. This was conducted to determine the \% parasitemia, survival rate, AST and ALT, blood-brain barrier (BBB) leakage, and neurobehavioral disorders in mice with CM. Results: The results showed that all treatments had significant antimalarial activity, with the \% suppression depending on the dose. It also indicates that PbA-infected mice had a survival rate of 11-19 days after infection, which was higher than those in the NC group. This suggested that curcumin and kaempferol have a protective effect on the survival of PbA-infected mice. Furthermore, they significantly reduced the AST and ALT concentrations in the sample compared to the NC group. The same was observed in cerebral vessel extravasation, where the Evans Blue stain assay showed significantly less dye extravasation in the brains of PbA-infected mice treated with curcumin and kaempferol. This indicated better-protected integrity of the BBB. Additionally, the results also demonstrated a decrease in neurological disorders arising during ECM in the group treated with curcumin and kaempferol. Conclusion: Considering these results, it is concluded that treatments with curcumin and kaempferol could improve animal survival, prevent AST and ALT elevations, as well as protect the BBB and neurobehavioral disorders associated with CM in PbA-infected mice.

Plants that have antioxidant content have been shown to have efficacy on the body, antioxidants have several drawbacks including being sensitive to environmental factors such as light, heat, pH, and oxygen. Microencapsulation is a method that has several advantages including providing several benefits, namely microparticles formulated to protect the core from the environment, cover up discomfort, maintain volatility or cell survival, separate incompatible substances, protect the body from side effects, and optimize, extend, or target drug effects. The choice of the type of polymer used will determine the characteristics of the microparticles produced, therefore a suitable coating material is needed to produce the microparticles. This review article was made to find out the results of research conducted in the manufacture of microparticles by using polymers which are expected to be useful to provide information on the basis of the selection of polymers and methods of making microparticles produced to maintain the stability of substances that are efficacious as antioxidants. Based on the results of the literature search, microencapsulation is a method used to maintain the stability of antioxidant content that has a therapeutic effect.
