Abstract

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.

Abstract

Inflamasi dapat menginduksi NOS (nitrat oksida sintase), yaitu enzim pengkatalisis pembentukan NO (nitrat oksida) berlebih sebagai pro-inflamasi. Akar kuning (Arcangelisia flava. L) banyak digunakan sebagai obat tradisional oleh masyarakat Asia Tenggara, baik sebagai obat luar maupun obat dalam. Senyawa kimia yang terkandung di dalam A. flava antara lain saponin, flavonoid dan tanin.  Akar tanaman ini juga mengandung glikosida dan alkaloid, terutama golongan isokuinolin, yaitu berberin, jatrorizin dan palmatin. Terdapat juga beberapa alkaloid minor seperti kolumbamin, dehidrokoridalmin, homoaromolin dan talifendin, serta diterpen fibraleusin. Fibraurin berpontensi sebagai anti-bakteri, anti-tumor, dan anti-inflamasi. Tujuan penelitian ini adalah untuk menelaah mode ikatan senyawa-senyawa kimia yang terkandung dalam A. flava terhadap enzim NOS dengan metode penambatan molekuler menggunakan perangkat lunak AutoDock. Hasil penelitian menunjukkan bahwa berberin, daidzein, dehidrokorildamin, epikatekhin, hidroksiekdison, jatrorizin, kaempferol, piknarin, kuersetin, dan talifendin dapat berinteraksi dengan enzim NOS pada kantung aktif  melalui pembentukan ikatan hidrogen dengan residu asam amino Glu377. Senyawa lainnya berinteraksi dengan residu asam amino tidak spesifik. Tidak ditemukan interaksi dengan Tyr347 pada semua senyawa. Hanya satu senyawa yang tidak membentuk interaksi dengan enzim NOS yaitu fibraurin.

Abstract

Ginger (Zingiber officinale) which belongs to the Zingiberaceae family, was first cultivated in Asia (Indonesia and Malaysia). This plant is one of the most commonly used herbal supplements taken by many patients to treat various conditions. Z.officinale has three varieties based on its size, colors of rhizome and chemical constituents i.e. .Z. officinale var. officinale (big white ginger or giant ginger, badak or gajah), Z. officinale var. amarum (small white ginger, emprit), and Z. officinale var. rubrum (small red ginger, merah or beureum). These three varieties may partly be deferred from their essential oil contents and are used for different purposes. The essential oils contained in Z. officinale var. rubrum are higher than the other types of ginger, which makes stronger in its pungency smell and taste. There are many studies that confirm beneficial effects of red ginger against the symptoms of diseases, i.e. anti-inflammation, antioxidant, antiemetic, antibacterial and antidiabetics. Z.officinale var. rubrum is considered to be a safe herbal medicine with only few and insignificant adverse/side effects. Although the medicinal properties of red ginger have been known, further trials in humans are required to determine the efficacy of red ginger (or one or more of its constituents) and to establish what, if any, adverse effects are observed.

Abstract

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

Abstract

The pharmacological activities of Plecranthus sp include anti-oxidant, antimicrobial, inhibition on cyclooxygenase (COX) and xanthine oxidase, and cytotoxic activity. The aim of this work was to study the antipyretic activity of P. scutellarioides (L.) extract on animal model. Twenty seven Swiss Webster male mice were divided into nine groups and were pyrexia-induced by using 0.1 ml of diphteria-pertussis-tetanus (DPT) vaccine. Their body temperature was measured every 60 minutes. After 4 hours of DPT vaccine injection, the mice were treated with (I) Arabic gum suspension (PGA) 2%; (II) paracetamol 16.25 mg/kg BW; (III) paracetamol 32.5 mg/kg BW; (IV) paracetamol 65 mg/kg BW; (V) paracetamol 130 mg/kg BW; (VI) P. scutellarioides extract 70 mg/kg BW; (VII) P. scutellarioides extract 140 mg/kg BW; (VIII) P. scutellarioides extract 280 mg/kg BW; (IX) P. scutellarioides extract 560 mg/kg BW. Data were analyzed using SPSS 21. Result showed that the body temperature of the mice started to rise at 2.5 hours and reached its peak at 4 hours after vaccine induction. The P. scutellarioides extract dose 280 mg/kg of BW indicated an 80.47% decrease (α= 0.05) compared to paracetamol dose 130 mg/kg of BW which decreases 85.43% of the animals’ fever. Interestingly, higher dose of the extract indicated a decrease in the antipyretic effect. We concluded that P. scutellarioides might possess antipyretic activity which started as early as 5 hours post vaccine-induced and was maintained for 3 hours. This plant needs further scientific exploration Keywords: Diphteria-pertusis-tetanus vaccine, anti-pyretic, rectal temperature, Webster mice

Abstract

Leucine catabolism changes among people with central obesity. This condition can lead to metabolic pathway disorder and increased mTORC-1 activation. Downstream signal of mTORC-1 is p70S6K1, which causes phosphorylation of insulin-1 receptor substrate (IRC-1). This study was performed to evaluate correlation between leucine concentration and insulin resistance (IR). This study was a prospective cross-sectional study, involving two groups; control and obese group. General characteristics and blood sample were taken from each subject. Leucin and Homeostasis Model Assesment (HOMA)-IR, as the marker of insulin resistance, were evaluated. The result indicated a significant positive correlation between leucine concentration and insulin resistance value (R=0.351; P=0.006) in central obese men. The higher leucine concentration, the higher the risk of insulin resistance occurrance. Therefore, leucine can be used as a biomarker for early detection of insulin resistance.Keywords: amino acids, mTORC-1, insulin-1 receptor substrate

Abstract

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

Abstract

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
