PHARMACEUTICAL PROPERTIES OF VENOM TOXINS AND THEIR POTENTIAL IN DRUG DISCOVERY Jeroen Kool
Indonesian Journal of Pharmacy Vol 27 No 1, 2016
Publisher : Faculty of Pharmacy Universitas Gadjah Mada, Yogyakarta, Skip Utara, 55281, Indonesia

Traditional pipelines feeding drugs coming to the market are declining. This is one of the reasons why nowadays the previously abandoned natural extract drug discovery programs are slowly coming back. In this scenario, small molecular metabolites from plants and single cell marine or soil organisms are gaining interest in pharmaceutical research again. Animal venoms are another source for finding new biopharmaceutical lead molecules and research interest in discovering bioactive molecules from venoms is rising. Venoms comprise often highly selective and potent bioactive peptides and small proteins for receptors and enzymes that are valid drug targets. This work discusses drug discovery research on bioactive compounds in venoms and gives older and more recent examples of bioactive compounds found in venoms from different animals. Common pharmaceutical targets that different classes of venom toxins interact with and information on developmental stages of several medicinal venom peptides are also discussed. Key words:venom, toxin, drug discovery, peptide, pharmaceutical activity

Aim of this research is to determine physical characteristic of ibuprofen-stearic acid due to compression force. Binary mixture of ibuprofen-stearic acid with weight ratio of 4:6, 5:5, and 6:4 was compressed under various compression force using hydraulic press with 13mm diameter flat punch.Identification of solid state interaction between these two components was performed by Hot Stage Microscopy (HSM). Physical characterization has been studied byDifferential Thermal Analysis (DTA), X-ray Powder Diffraction (XRPD), Scanning Electron Microscopy (SEM), and (Fourier Transform Infrared (FT-IR) spectroscopy. According to hardness measurement, 4:6 weight ratio has the highest tensile strength on 170.6N/cm2 under 19.93kN compression force. Interaction identification by HSM showed single blank line that indicates eutectic formation. Thermal analysis of DTA also revealed eutectic formation upon compression whichthe endotermic peak of ratio of 4:6has the lowest melting temperature of 53.2°C. X-ray diffraction of three peaksgenerally showed that peak intensity decreases as compression force increases, but at particular point it begins to increase again. Sintering phenomenon at the surface of compressed tablet was observed from SEM analysis. FT-IR study confirms the formation of simple eutectic. Key words: ibuprofen, stearic acid, binary mixture, compression force, physical characterization

Due to worldwide phenomenon of microbial resistance to commonly used therapeutic agents, antibiotics and antifungals, dibasic di‑/trimethylphenylcarbamic acid esters 1–3, a non-traditional series of potential antimicrobials, has been in vitro evaluated against chosen Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacterial strains as well as against yeast (C. albicans) by the minimum inhibitory concentration (MIC) assay. Taking into consideration chemical structure of tested derivatives, the incorporation of more than one protonated atom of nitrogen into salt forming fragment positively influenced the activity against E. coli. On the contrary, the presence of one or more methyl groups instead of 3-alkoxy side chain attached to lipophilic aromatic moiety has not found to be favorable structural feature. In entire set of inspected compounds, the most promising results have been found for the compound 3, chemically1-[3-piperidinium-1-yl-2-({[(2,4,6-trimethylphenyl)amino]carbonyl}oxy)propyl]piperidinium dichloride, against E. coli with the MIC=1.56 mg/mL. Key words: Dibasic phenylcarbamic acid esters, Escherichia coli, hydrogen bonding, lipophilicity
