Tuberculosis is a fatal airborne disease caused by bacteria from the Mycobacterium tuberculosis complex (MTBC). The incidence of contracting tuberculosis is estimated to be around 10.6 million cases each year. Increased drug resistance among mycobacteria has led to the need to develop new treatments. The study's purpose was to determine the antimycobacterial ability of drug complexes and how toxic these complexes are against human cells. Drug complexes from "phage derived endolysins" and "A pyrazine amide-4 aminoquinoline hybrids" were studied to possibly be included as a treatment against tuberculosis in the future. The minimum inhibitory concentrations (MIC) of the drug complexes were analyzed by the method Resazurin microtiter assay (REMA), where the results were assessed visually. The toxicity of the drug complexes was studied by growing THP1-Blue™ NF-κB cells, which then were exposed to the drug complexes. The results could then be obtained by absorbance measurement with spectrophotometry. One-way ANOVA showed a non-significant value, as the P-value was 0.44 (P>0.05). However, more supplementary studies need to be carried out to obtain a significant result. All performed concentrations of the drug complexes were assessed as non-toxic against human THP1-Blue™ NF-κB cells. / Tuberkulos är en dödlig luftburen sjukdom som orsakas av bakterier från Mycobacterium tuberculosis complex (MTBC). Den årliga incidensen i världen för insjuknande i tuberkulos beräknas vara 10.6 miljoner. Ökad läkemedelsresistens bland mycobakterier har lett till att nya behandlingar behöver utvecklas. Syftet med studien var att studera två olika läkemedelskomplex antimycobakteriella förmåga samt hur toxiska dessa komplex är mot humana celler. Läkemedelskomplex från "phage derived endolysins" och "A pyrazine amide-4 aminoquinoline hybrids" studerades för att eventuellt kunna ingå som behandling mot tuberkulos framöver. Läkemedelskomplexens minsta inhibitoriska koncentration (MIC) analyserades genom metoden Resazurin microtiter assay (REMA) där resultaten bedömdes visuellt. Läkemedelskomplexens toxicitet studerades genom odling av THP1-Blue™ NF-κB celler som sedan exponerades för läkemedelskomplexen och resultaten kunde sedan fås genom absorbansmätning med spektrofotometri. One-way ANOVA påvisade ett icke-signifikant värde, då p-värdet blev 0,44 (P>0,05). Dock behövs fler kompletterande studier genomföras för att studera detta ytterligare. Alla studerade koncentrationer av läkemedelskomplexen bedömdes vara icke-toxiska mot humana THP1-Blue™ NF-κB celler.
