Abstract

A study has been conducted on the synthesis of mesoporous silica as introductory material pinostrobin anticancer compounds. The aim of this study was to synthesis paramagnetic mesoporous silica from rice husk ash waste; knowing the characteristics of silica gel and mesoporous silica from rice husk and the value of adsorption capacity (Q). Based on the results of the study, it was found that mesoporous silica can be synthesized from the rice husk ash waste. Characterization using FTIR produces silanol (Si-OH), and siloxan (Si-O-Si). The use of 30% w/w tartaric acid as a template doesn’t change the functional groups of silica. The optimum conditions of adsorption of pinostrobin compounds by mesoporous silica at the adsorption capacity of 7.049 mg/g. In simulated intestinal fluids (pH 7.4),pinostrobin is released slowly at every hour, then slightly increases at the 10th hour and continues to increase again slowly so that the pinostrobin compound is completely released at 12 hours.

Abstract

Synthesis of paramagnetic silica from rice husk ash has been carried out as an adsorbent for heavy metal Ag (I). This study tried to synthesis and characterized the thermodynamics and kinetics behaviour of paramagnetic silica from the husk ash as metal adsorbent Ag (I). Determination of optimal conditions for adsorption of metal ions Ag (I) is carried out by varying the pH, concentration, and contact time of the adsorbent. The results showed that the optimum pH was at pH 3, optimal concentration Ag(I) of 350 ppm and optimal contact time of 90 minutes. At optimal conditions, paramagnetic silica adsorption capacity for metal ion Ag (I) is 323.62 mg/g. The isotherm model that is suitable for paramagnetic silica is the Freundlich isotherm model. The kinetic model that is suitable for paramagnetic silica is the Pseudo Order 2 kinetic model.

Abstract

Acne or commonly referred as Acne Vulgaris is a chronic skin disease due to abnormalities of sebum production in sebaceous glands caused by Staphylococcus epidermis bacteria. Acne treatment is usually done by using antibiotics, both topical and oral like Clindamycin 1%. However, the long-term use of antibiotics might lead to resistant of Propionibacterium acne strains or immune to Clindamycin 1%. People in Bima, particulary in Wawo district have local wisdom, that is facial using Bongi Me’e which is a traditional scrubs made of rice, tamarind, and temu giring extract that officacious as antibacterial. The purpose of this study was to determine the effectiveness of Bongi Me’e liquid soap as the antibacterial against Staphylococcus epidermis. In this research, four soap formulas were formulated and tested using well diffusion method. Formula 1 (4 ml rice extract, 3 ml temu giring extract and 2 ml tamarind extract). Formula 2 ( 2 ml rice extract, 3 ml temu giring extract and 4 ml tamarind extract). Formula 3 (2 ml rice extract, 4 ml temu giring extract, and 3 ml tamarind extract). Formula 4 (4 ml rice extract, 2 ml temu giring extract, and 3 ml tamarind extract). The inhibitory zone test indicated that the highest diameter of inhibition zone obtained in the formula 1 of 29,3 mm, followed by the formula 2 of 28 mm, formula 4 of 26,6 mm, and formula 3 that has smallest inhibitory zone by 25 mm. So, the antibacterial Bongi Me’e liquid soap was effective to inhibit acne-cause bacteria Staphylococcus epidermis

Abstract

Quantitative Structure-Activity Relationship (QSAR) study have been performed on Xanthone derivatives as anti-cancer activity. The objectives of this research is to design a new Xanthone derivatives from the best QSAR equation model. The data set were taken from the previous study, involving 41 Xanthone derivatives and their biology activities in Inhibitor Concentration 50 % (IC50). The parameters (descriptors) were calculated by semiempirical PM3 method. The selection of the best QSAR equation models was determined by multilinear regression analysis. The best linear equation resulted from that analysis is: Log 1/IC50 = 13,099 + 2,837 qC1 + 0,098 qC2 + 11,214 qC10 + 2,065 qC13 – 1,236 qC14 + 35,356 qO15 + 0,001 (vol) – 0,025 (log P) + 0,283 (dipole) n = 41; r = 0.735; adjusted r2 = 0.360; Fhit/Ftab = 1.2911; PRESS = 5.0089. Based on that model, a new Xanthon derivatives has been design which show better predicted biology activity (log 1/IC50= 15,0863), new derivatives have the log 1/IC50 higher than the old one (log 1/IC50= 9). This result indicated that new Xanthone derivatives has potential to developed as new anti-cancer drug

Abstract

Corrosion is a process of metal destruction due to the metal-acidic environment reaction. The uncontrolled corrosion process lead to massive losses. Administering inhibitors of organic compounds on the metal surface may prevent the corrosion processes. Organic inhibitors are low toxicity, environmentally friendly, effective easy to obtain and cheap. The study aims to determine the effect of substituents to the efficiency of corrosion inhibition of imidazole in carbon steel based on quantum chemical parameters. Corrosion inhibition efficiency values ​​are strongly influenced by the addition of substituents namely electron donors (CH3, CHCH2, NH2, CH2OH and OH) and electron withdrawal (CHO, COOH, NO2, F and Cl). The addition of amine group NH2 increased the corrosion inhibition efficiency to 91 % whereas amino group NO2 reduced the efficiency of corrosion inhibition to 64 %. Analysis of the Fukui function shows that imidazole has active sides on the C1 and C3 atoms. NBO analysis shows that there is an interaction of N5 atoms that donate electrons to Fe13 at 8.67 kcal.mol-1. In conclusion, the addition of an electron donor group increases the efficiency of corrosion inhibition of imidazole.
