Abstract

Polycyclic aromatic hydrocarbons (PAHs) are a class of organic chemicals, composed of fused benzene rings, occurred in the environment due to incomplete combustion of fossil fuels. Health concerns are focused on the metabolite transformation of PAHs, which is carcinogenic, mutagenic and terratogenic. Due to their hydrophobicity in aquatic environment, PAHs are accumulated to the more lipophilic ecocompartments such as biolipid tissues and sediments, so PAHs can be distributed through food chain system. In this research, five kinds of PAHs (i.e. pyrene, benz(a)anthracene, benz(k)fluoranthene, benz(a)pyrene and perylene) in shrimps (Panaceus merquensis) and crabs (Calappa flammea) collected from the south sea beach water system at Jogjakarta were investigated. PAHs analysis were worked out by gas chromatography with flame ionization detector. It can be shown from this research that PAHs accumulate into each biota.The results showed that bioacumulation factor value of total PAHs in shrimp and crab are 2388.33-23486.54 and 13870.92-96078 respectively. The logarithmic value of bioacumulation factor of total PAHs in shrimp and crab are 3.378-4.371 and 4.142-4.983 respectively. According to the World Health Organization (WHO) recommendation, the level of PAHs concentration in water sample is safe.Key words : polycyclic aromatic hydrocarbons, bioacumulation, shrimp (Panaceus merquensis) and crab (Calappa flammea)

Abstract

Molecular dynamics (MD) simulation has been applied to curcumin, 4-methyl curcumin and 4-isopropil curcumin. They have reducting activities on Ferri to Ferro. A computation method used is AM1 (Austin Model 1) semiempiric method. Studying of computation is arranged to theoretical studying of structure and reactivity relationship on these molecules without solvent interaction (in vacuo). The time of simulation is taken from 0 – 10 ps (pico secon) with interval 0,0005 ps on 300oK. The result of experiment that has been proposed from the MD simulation is the structure of conformation trajectory of each molecules. By considering total energy and potential energy changes to time of simulation, along with the change of bonding length, bonding angle, and the atomic charges of -diketon active site to time of simulation. Reactivity of these molecules are analyzed from the geometric shape of the active site indicated that 4-isopropyl curcumin was the most reactive than the other to produce complex with Ferri, while 4-methyl curcumin within the complex was easiest in the reduction of Ferri to Ferro.Key words : molecular dynamic, curcumin, reduction

Abstract

Viteosin-A, a tracheospasmolytic compound, was successfully isolated from n-hexane extract of the leaves of Vitex trifolia L. With the concentration of 0.05 and 0.15 mg/ml viteosin-A inhibited a guinea pig tracheal contraction due to histamine (10-7 – 10-3 M) in vitro by 27.1 and 47.9 %, respectively. Confirmation of C-5 and C-6 configuration is necessary to determine the active reaction site of viteosin-A and its receptor for future development. This research was focused on a molecular modeling of viteosin-A using computational method with HyperChem Pro 4.0 for Windows as software. Based on spectroscopic data and molecular modeling, viteosin-A has S configuration at C-5 and C-6, and therefore was confirmed as (5S,10S)-6S-acetoxy-8R-methyl-9-hidroxy-labda-13Z-en-16,15-olide.Keywords: viteosin-A, molecular modeling
