Agelas sponge is found in abundancy from Indonesiaâs ocean. This sponge produces an important chemotaxonomic group of compounds, derived from pyrrole-imidazole alkaloids. This group of compounds is one of those exclusively found from marine environment. Marine sponges are reported to be promising drug lead producers having unique chemical structures of which many have no terrestrial counterparts. The objective of this report is to give an overview of the reported attempts from up to down stream to develop pyrrole-imidazole alkaloids as new drug lead. Literatures up to 2013 reporting this group of compounds from Agelas sponges were studied. Discussion on the halogenated alkaloids covers the producers, description of high chemical diversity, identification, biosynthesis and ecological relevance as well as their role as a promising drug candidate. Alternatives to provide continous supplies for drug development are also discussed considering that wild harvesting of the sponge producers can lead to ecological damage in the future . Broad range of interesting pharmacological importance as well as several success in developing synthetic route for production supports its development as drug candidate.Â

Morinda citrifolia L. fruits are rich in polysaccharides of which are non toxic and possess hospes-mediated-antitumor potential. In Indonesia, noni fruit has been used empirically to enhance immune system. Previous research revealed that noni polysaccharide-rich fraction showed macrophage activity enhance-ment. This research aimed to optimize the method of noni-polysaccharides-rich fractionation using four different methods for polysaccharide isolation (method I, II, III, IV) and to evaluate the immunostimulatory effects of the isolated polysaccharides on macrophages and lymphocytes activities. Immunostimulatory effects were examined on male Balb/c mice in vitro. The polysaccharides were evaluated by phenol sulfuric acid test. Qualitative methods were used to detect the phytochemical characteristic. Total phenolic content was determined by using Folin-Ciocalteau method. The study showed different methods resulted in different yields, phytochemical characteristics and immunostimulatory activities of polysaccharides-rich fraction. The phytochemical test from method I, III and IVb revealed the presence of alkaloid. Method II resulted fractions with the presence of saponin. There were no protein and phenolic substances detected from all methods. The highest result of polysaccharide content was found in method IVb (32.58%). Method III showed the highest activity on phagocytic activity of the macrophage, while method IVb exhibited the highest stimulation on lymphocyte proliferation.Key words: Isolation method, polysaccharide, Morinda citrifolia L. immunostimulatory effect

Biofilms associated with human infection have high levels of pathogenicity due to their resistance to antibiotics. The discovery of an active antibiofilm agent against polymicrobial biofilms is a necessary consequence for coping with biofilm-related infections. Thymol and Eugenol are essential oils that have potential as antibacterial and antifungal. This study aimed to determine the effectiveness of thymol and eugenol inhibits C. albicans, P. Aeruginosa, E. coli S. aureus and polymicrobial biofilm. Biofilm formation inhibition assay and biofilm degradation assay of thymol and eugenol were determined using microtiter broth method.The antibiofilm efficacy of thymol and eugenol towards polymicrobial biofilms were analyzed by calculating minimum biofilm inhibitor concentration (MBIC50) and minimum biofilm eradication concentration (MBEC50) values. The data were analyzed using Statistical Package for the Social Sciences (SPSS) with 95% confidence level. Thymol and eugenol showed inhibitory activity against the formation of mono and polymicrobial biofilms of the microbial tested.The result also demonstrated an evidence of activity of thymol and eugenol in breaking down mono and polymicrobial biofilm. Therefore, thymol and eugenol serves as a potential source for new antibiofilm drugs towards polymicrobial biofilm.

Dental plaque is a mouth cavity health problem related to microbial biofilm, where Streptococcus mutans is predominant. Adding of essential oils blend in mouthwash has been reported to increase the dental plaque inhibitory activity. The essential oils of clove leaves (Syzygium aromaticum (L.) Merr. & Perry) and cinnamon cortex (Cinnamomum burmanniNees ex Bl.), are known as potential antibacterial and antibiofilm towards S. mutans. This research aims were to reveal the influence of blending the clove leaves and cinnamon cortex essential oils in antibacterial and anti biofilm activity against S. mutans and to find out the optimum composition. Antibacterial assay was performed in nutrient broth media, on microplate flat-bottom polystyrene 96 wells. Biofilm formation inhibition and degradation assays were done in BHI + 2 % sucrose on microplate flexible U-bottom PVC 96 wells. Crystal violet1 % was used to stain the biofilm and Optical Density(OD) was measured at λ 595 nm. Simplex Lattice Design formula was used to calculate the blend optimum composition. TLCbioautography and GC-MS assays were done to revealthe active substances. As conclusion, it was proven that blending the clove leaves and cinnamon cortex essential oils increased the antibacterial and biofilm degradation potency, but reduced the biofilm formation inhibitory effect against S. mutans. The optimum composition of the essential oils blend was 27:73 (% v/v). From our results we suggest that the clove leaves and cinnamon cortex essential oil blend used in this study be developed as anti dental plaque.Key words : clove leaves, cinnamon cortex, essential oils blend, Streptococcus mutans

Makutadewa (Phaleria macrocarpa (Scheff) Boerl.) is one of the herbal medicines used against cancer, however, the scientific basis of the activity still void. Daphne mezereum, the same family (Thymelaeaceae) to makutadewa has been proved to contain cytotoxic substances in its bark. Therefore, the aims of this research were to investigate the toxic effect of makutadewa bark against Artemia salina Leach. as the primary step to identify an anticancer activity and find out substances responsible to this activity. The material powder was extracted using Soxhlet apparatus with chloroform, followed by methanol and finally by distilled water. The toxicity of chloroform, methanolic and aqueous extracts were assayed against A.salina Leach. The chloroform extract (most active) with the LC50 of 29.6 0.14 g/ml was fractionated by vacuum liquid chromatography using wash benzene 100 % (a); wash benzene-ethyl acetate =20:1 (b); 15:1 (c); 10:1 (d); 5:1 (e); 2:1 (f) and chloroform-methanol 1:1 (g) as mobile phases. The active fractions against A.salina were E {combination of (e) and (f)} with LC50 of 106,9 g/ml and F (g) with the LC50 of 131,53 g/ml, hence less toxic than the original extract. The thin layer chromatogram profiles showed that E and F fractions contained terpenoid and alkaloid substances.Key words: toxicity test, (Phaleria macrocarpa (Scheff)Boerl.), bark
