Cyclooxygenase (COX), an enzyme involved in the conversion of arachidonic acid to prostaglandins, exists in two isoforms, which are COX-1 and COX-2. Despite the similarities of COX-1 and COX-2, the two isoforms show subtle differences in amino acid composition at the active sites. Since COX-1 has isoleucine, a bulkier amino acid at position 523 than COX-2's valine, it allows COX-2 to have a larger space in its active site. Andrographolide reduces COX-2 expression induced by PAF and fMLP in HL60/neutrophils. Neoandrographolide inhibits COX-2 expression at the translational level. The purpose of this study is to examine the binding modes of andrographolide and neoandrographolide against COX-1 and COX-2 in terms of hydrogen bonds and docking energy, to understand their antiinflammatory property. The docking simulation indicates that both andrographolide and neoandrographolide are able to be located in the COX-2's binding pocket but not in the COX-1's. It confirms that COX-1's binding pocket is smaller than COX-2's. Based on this study, both andrographolide and neoandrographolide show selective inhibitory property to COX-2. Their selectivity are due to their specific interaction with Arg 513 in the binding pocket of COX-2, which is also shown by SC-558, a COX-2 selective inhibitor.

Quinine is a natural alkaloid having a methoxy group bound to quinoline ring and an allyl group bound to quinuclidine ring. Demethylation of quinine applying strong acid such as HBr or HI at high temperature was unsuccessful. The aim of this research was to obtain demethylated quinine by means of mild and selective demethylation procedure to prevent the addition reaction of allyl group. Selective demethylation of quinine has been carried out using anhydrous aluminium trichloride as reagent. The demethylation product was achieved in 68.12% yield by mole ratio of quinine to anhydrous aluminium trichloride of 1 to 4 in dried methylene chloride under nitrogen atmosphere. The reaction was firstly carried out at 0°C for 4 h and after the reaction mixture reached room temperature, the reaction was continued up to 24 h.

The urokinase-type plasminogen activator (uPA) system plays a significant role in the invasion and metastasis of cancer cells. The present study was conducted to investigate natural product compounds as inhibitors and hit molecules of uPA using in-silico analysis. A pharmacophore model was built to screen the Indonesian Herbal Database (HerbalDB) to obtain inhibitors of different scaffolds. Based on the molecular docking score, four ligands were selected as potential uPA inhibitors. Subsequently, the stability of the ligand-uPA complex was analyzed using molecular dynamics (MD) simulation. An RMSD graph of the backbone protein and the RMSF values of the amino acid residues were also determined. In addition, the MM-PBSA method was applied to calculate the free binding energy. According to the results, Model_3, characterized by aromatic rings 23 (F1 and F2), cationic H-bond donor (F3), and metal ligator (F4) features, had an adequate goodness-of-hit score (GH). The four top-ranked ligands, isorhamnetin, rhamnetin, quercetin, and kaempferol, showed higher docking scores compared to the others. This study confirmed that isorhamnetin, rhamnetin, and kaempferol build stable complexes with uPA with lower binding energy than quercetin.

In Indonesia, red ginger (Zingiber officinale var. Rubrum) is usually used as topical pain reducer by directly applying the fresh rhizome. The aim of this research was to provide information regarding the pharmacological activity of Z. officinale var. Rubrum rhizome infusion on the rate of prostaglandin production. The Z. officinale var. Rubrum rhizome used in this research was purchased from Research Institute for Spices and Medicinal Plants (Balittro) Manoko Lembang, West Java, Indonesia. This research was conducted by applying TMPD (N,N,N’,N’-tetramethyl-p-phenylendiamine) as the reagent. COX-1 and COX-2 enzyme inhibitory activity can be seen from TMPD chromogenic changes that occur during PGG2 reduction to PGH2. Phytochemical screening showed that flavonoid, quinone, and monoterpenoid/sesquiterpenoid were detected in both dried rhizomes and the water extract. Three spots were detected on thin-layer chromatography system which employing chloroform-methanol (5:5) as the eluent. The rate of prostaglandin formations either by Z. officinale var. Rubrum rhizome infusion or acetylsalicylic acid on COX-1 is slower (at 25th minutes) rather than COX-2 (5th minutes). We concluded that the rhizome of Z. officinale var. Rubrum reduces the rate of prostaglandin production. The rhizome of red ginger reduces the rate of prostaglandin production, which is slower in COX-1 than in COX-2. This plant could be further developed as anti-inflammatory drug candidate.Keywords: acetosal, antiinflammation, cyclooxygenase, NSAIDs, red ginger

An HPLC method was developed and validated for the pharmacokinetic drug-drug interaction between Andrographis paniculata and ibuprofen in the plasma of Oryctolagus cuniculus rabbits after a single oral administration of the mixture. Nine healthy rabbits (6 males and 3 females, weight 1.68-2.42 kg) were acclimatized for 7 days and were randomly divided into 3 groups. At day-8th the rabbits were group (1) treated with a single oral administration of ibuprofen (dose of 28 mg/kg BW); group (2) treated with a single oral administration of Andrographis paniculata infusion (7.04 mL/kg BW); group (3) treated with a single oral administration of a mixture of Andrographis paniculata (7.04 mL/kg BW) infusion and ibuprofen (dose of 28 mg/kg BW). Plasma samples were prepared by collecting the blood from the marginal ear vein at 0, 30, 60, 90, and 120 minutes after the mixture administration, followed by centrifuging it for 30 minutes 3000 rpm. Chromatographic separation was performed on a LiChrosorb RP-18 with methanol and double-distilled water (70:30) as the mobile phase, flow rate 1 mL/minute. UV detection was set at 227 nm. The absorption and distribution of ibuprofen were fast (Tmax = 30 min; Cmax = 4.02962 mcg/mL), however, interestingly this drug could improve the absorption and distribution of andrographolide in Oryctolagus cuniculus rabbits

Cyclooxygenase (COX) or prostaglandin H2 synthase (PGHS) catalyzes the conversion of arachidonic acid into prostaglandins. Nonsteroidal anti-inflammatory drugs (NSAIDs) work by inhibiting both COX-1 and COX-2 isoforms, thus disturbing this reaction. In Indonesia, Andrographis paniculata (local name: sambiloto), is empirically used to reduce inflammation by consuming the herb tea of this plant. This work studied the inhibitory activity of andrographolide and andrograpanin, diterpenoids of the plant, on the rate of prostaglandin formation. Previous works have proven that andrographolide inhibited PGE2 production in LPS-induced human fibroblast cells. This study was performed by measuring the absorbance of TMPD (tetramethyl-p-phenyldiamine) oxidized by andrographolide and andrograpanin. Acetosal was used as a control drug. The rate of PGH2 formations on either COX-1 or COX- 2 was affected by andrographolide and andrograpanin. Andrographolide and andrograpanin interact longer with COX-1 than COX-2. Andrographolide shows weak inhibition on the rate of PGH2 formation, whilst andrograpanin might be further developed for potential antiinflammatory drugs.Keywords: Andrographis paniculata, anti-inflammatory, COX, cyclooxygenase, prostaglandin

The research related to the interaction study, synthesis and characterization of molecular imprinted polymer using dimethylamylamine (DMAA) as the template molecule and the functional monomer methacrylate acid has been conducted. Molecular Imprinted Polymer (MIP) is a separation method made by the molecule template in the polymer matrix followed by removing the template molecule by washing for giving the permanent framework groove. The MIP was made by mixing the DMAA as the template molecule, with the methacrylate acid as the functional monomer, and the ethylene glycol dimethacrylate (EGDMA) as the crosslinker with the ratio 1:6:20. Porogen solvents used were the chloroform and the initiator azobisisobutyronitrile (AIBN). The crystal MIP and the NIP without the DMAA were characterized using Infrared Spectrophotometer (FTIR), and the result showed that there have been differences among the MIP, the NIP and the MIP after being extracted. The characterization using Scanning Electron Microscope (SEM) showed that the NIP as the comparison having flat morphology, while the MIP having irregular morphology and less pores. Then the MIP after being extracted has irregular, rough morphology and a lot of pores. The result reveals the interaction between the DMAA and the methacrylate acid that is the hydrogen bonded with the Gibbs free energy obtained is -5.434 j/mol. The imprinting factor of 2,353 is obtained. The highest desorption descending capacity is chloroform with the MIP 738% better. For the MIP and NIP methanol, it is found that the MIP is 123% better. Then the MIP which is desorbed by the chloroform is better 602% than the MIP resorbed by the methanol, and the ethyl acetate cannot desorb the DMAA.
