Abstract

Analysis of N-nitrosodiprophylamines carcinogenic compound in processed meat especially hamburger and kebab had occured by HS-SDME-GC-FID technique. The results were obtained determining the optimum pH was 4, the optimum stirring speed was 6 scale, and the temperature of extraction was 30 ºC. It was obtained in this study that the detection limit of 78 ppb, the percent recovery of 101,18%, precision between 0,089% to 0,566%, and the true enrichment factor was 3372,66 times. From the results of the study was concluded that HS-SDME-GC-FID technique can be used to analyze the carcinogenic compound N-nitrosodiprophylamines (NDPA) found in meat-processing (hamburger and kebab) by the concentration of each samples as follows, hamburger I of 0,27 ppm, hamburger II of 0,73 ppm, hamburger III of 1,39 ppm, and kebab I of 3,13 ppm

Abstract

The human immunodeficiency virus (HIV) is viruses known as rotaviruses. Potential target for therapeutic is reverse transcriptase (RT), possesses an RNA dependent DNA polymerase, DNA-dependent DNA polymerase and ribonuclease H fuctions. Imidazoles have high anti-HIV inhibitory activity, some derivates of imidazole reported drugs. 8-chloro-2,3-dihydroimidazole[1,2-b] [1,4,2]benzodithiazine-5,5-dioxides and 9-chloro-2,3,4-trihydropyri-mido[1,2-b][1,4,2]benzodithi-azine-6,6-dioxides. This compounds succesfully identified anti-HIV activity. Copper is a bio-essential element and copper complexes have been extensively utilized in metal mediated DNA cleavage for the generation of activated oxygen species. It has been reported that teraaza macrocyclic copper coordination compounds have anti-HIV activities. Studies have shown that these macrocyclic complexes can react with DNA in different binding fashions and exhibit effective nuclease activities. Complex compounds are compounds in which there is an atom that acts as the central atom and trotter group of molecules that can be either neutral or charged ions. Application a metal-organic (complex) compounds, especially copper metal and derivates of imidazole. So, in this study can explore new anti-HIV candidate.
