"Malaria merupakan salah satu penyakit infeksi yang paling berbahaya. Data WHO pada tahun 2023 melaporkan sebanyak 249 juta kasus malaria di dunia. Hal ini menunjukkan bahwa penyakit malaria memerlukan tindakan penanggulangan. Namun, maraknya kasus resistensi obat antimalaria menjadi salah satu penghambat dalam upaya tersebut, salah satunya resistensi obat antimalaria atovaquone. Untuk itu, dibutuhkan suatu upaya penanggulangan penyakit malaria, salah satunya adalah dengan pengembangan obat antimalaria baru. Diketahui bahwa tumbuhan mangrove Sonneratia alba memiliki potensi antimalaria terhadap Plasmodium berghei secara ex vivo. Penelitian ini bertujuan untuk mengetahui aktivitas antimalaria ekstrak metanol S.alba terhadap beberapa jenis P.berghei resisten terhadap atovaquone secara ex vivo dan in vivo, serta prediksi interaksi ikatan kimia senyawa utamanya secara in silico. Uji antimalaria secara ex vivo dengan konsentrasi ekstrak 100, 30, 10, 1 μg/mL menghasilkan nilai IC50 dari rentang 16,26 μg/mL – 39,08 μg/mL. Secara in vivo ekstrak metanol S.alba dengan dosis 100, 30, 10, 1 mg/kg BW tidak menunjukkan aktivitas antimalaria. Secara in silico, dua senyawa utama yang terkandung memiliki ikatan kimia kuat dengan model protein mitokondria sitokrom b P.berghei yaitu oleanolic acid dan fipronil. Uji keamanan ekstrak terhadap mencit sehat juga dalam kategori aman. Oleh karena itu, penelitian ekstrak metanol S.alba sebagai kandidat antimalaria perlu dikembangkan.

Malaria is one of the most dangerous infectious diseases. WHO reports in 2023, 249 million malaria cases happened in the world. So that, malaria requires control measures. However, increasing number of antimalarial drug resistance cases is a burden, one of them is antimalarial drug atovaquone resistance. For this reason, development of new antimalarial drug candidate are needed. Previous study reports, Sonneratia alba mangrove plant has antimalarial potency against Plasmodium berghei in ex vivo. This study aims to determine the antimalarial activity of S.alba methanol extract against several types of P.berghei resistant to atovaquone ex vivo and in vivo, also predicted chemical bond interactions of the main compounds in silico. Ex vivo antimalarial tests with extract concentrations of 100, 30, 10, 1 μg/mL showed IC50 values in the range16.26 μg/mL – 39.08 μg/mL. In vivo, methanol extract of S. alba in 100, 30, 10, 1 mg/kg BW dose did not show antimalarial activity. In silico, the two main compounds have strong chemical bonds with mitochondrial cytochrome b protein of P.berghei model, namely oleanolic acid and fipronil. Safety test of the extract tested on healthy mice was also in the safe category. Therefore, development of methanol extract of S. alba as antimalarial candidate needs further research."

"Kesimpulan dari penelitian ini adalah artemisinin mono-theraphy menurunkan derajat parasitemia sama efektifnya dengan kombinasi artemisinin and NAC. Terapi kombinasi artemisinin dan NAC, dosis konstan maupun tapering, lebih meningkatkan kadar IL-12p70 plasma daripada artemisinin mono-therapy. kadar IL-12p70 plasma tertinggi ditekan pada kelompok yang diterapi kombinasi artemisinin dan NAC dosis tapering pada pengobatan selama 7 hari."

"Telah dilakukan penelitian isolasi dan karakterisasi molekuler Plasmodium berghei yang resistan terhadap artemisinin in vivo. Penelitian bertujuan mengetahui keterkaitan polimorfisme gen pbatp6 dengan resistensi P. berghei terhadap artemisinin. Penelitian dilakukan di Lembaga Biologi Molekul Eijkman (LBME), Jakarta, selama 12 bulan (April 2006—Maret 2007). Empat isolat P. berghei yang resistan terhadap artemisinin pada dosis 15 dan 250 mg/kg berat badan berhasil diisolasi melalui pengobatan dosis subletal bertingkat selama tiga hari berturut-turut pada mencit galur BALB/c yang diinfeksi P. berghei. Uji resistensi obat yang dilakukan untuk membandingkan pola pertumbuhan parasit galur parental dan salah satu isolat yang resistan menunjukkan adanya peningkatan ED50 sebesar 2,8 kali lipat. Analisis molekuler dengan teknik polymerase chain reaction (PCR) menggunakan primer forward PbATP6-F1 dan reverse PbATP6-R1 dan DNA sequencing menunjukkan adanya perubahan basa guanin menjadi adenin pada nukleotida ke-355 gen pbatp6. Perubahan tersebut mengakibatkan perubahan asam amino dari asam glutamat (E) menjadi lisin (K) pada residu ke-119 yang terletak pada domain transmembran M2 dari protein putatif PbATP6. Perubahan asam amino tersebut belum pernah dilaporkan sebelumnya. Hasil penelitian menunjukkan adanya kemungkinan polimorfisme gen pbatp6 yang diduga berperan pada resistensi P. berghei terhadap artemisinin."

ABSTRACTMalaria is still the main health problem in the world, mainly in tropical countries since its incidence of illness and death is high. The severe symptoms, which may lead to death, are affected not only by the immune response of each individual but also by the efficacy in the malaria treatment. The purpose of this research is to investigate the effect of immune response (TNF-α) of the Plasmodium berghei infected mice which was treated with the pasak bumi root extract as antimalaria. This was in vivo experimental study in which the experimental animals were divided into five different groups (control, Plasmodium berghei and aquades, CMC, Plasmodium berghei and CMC, Plasmodium berghei and pasak bumi root extract). The level of parasitemia were determineted by using thin and thick blood staining. The bead based multiplexing technique was used in the TNF-α examination in order to obtain mean fluorescence intensity (MFI) which was later used as TNF-α standard. The results of this research showed the potential of the pasak bumi root extract as antimalaria with the mean percentage of growth inhibition was 88.93%. The correlation analysis showed a meaningful relation between the parasitemia level and TNF-α (Spearman test, r= - 0,838; p=0.002). This means that the pasak bumi root extract could activate TNF-α which acts as immune protector. In conclucion, the pasak bumi root extract could enhance the TNF-α expression as shown by the decline of the parasitemia level in the Plasmodium berghei infected mouse"
