Özet

AIDS is a global disease caused by HIV, affecting millions of people and causing death. The current limitations of antiretroviral therapy used in the therapy of HIV/AIDS have led to the need to search for new and effective drugs from natural products, especially plants. Herewith, using the present study, the detection of HIV-1-RT inhibition of aqueous extract of Satureja spicigera (C.KOCH) BOISS. was performed for the first time. Besides, total phenolic content (TPC), analysis of phenolic constituents by RP-HPLC-DAD and antioxidant capacity by DPPH and Ferric reducing antioxidant power (FRAP) methods were determined for the first time. In addition, molecular docking studies were carried out between HIV-1-RT and phenolic substances, the presence of which was determined in the aqueous extract, for the determination of the phenolics that may be responsible for HIV-1-RT activity. HIV-1-RT inhibition was defined as IC50: 22.83 mu g/ml. Benzoic acid, vanillin, rutin, and chlorogenic acid were present as main phenolics in quantities of 621.96, 505.87, 349.33, and 323.23 mu g phenolic/g extract, respectively. Further, TPC, DPPH, and FRAP were calculated as in the order of 151.69 mg GAE/g extract, 23.77 mu g/ml, and 445.7 mu mol TE/g extract. Chlorogenic acid (-8.48 kcal/mol) was found to be the most effective ligand in docking studies, with a value close to positive standard nevirapine (-9.35 kcal/mol). Hereby, although the aqueous extract of S. spicigera can be used as a natural antioxidant, the crude extract or its phenolics have the potential to be used in the treatment of AIDS due to its high HIV-1-RT activity. Practical applications In this study, anti-HIV-1-RT and antioxidant activity and total phenolic content of Satureja spicigera aqueous extract were determined. In addition, HPLC analysis of some phytochemicals and the activities of these phytochemicals against HIV-1-RT enzyme was determined by molecular docking studies. The results showed that the aqueous extract of S. spicigera and some of the phytochemicals it contains have the potential to be used as a natural product against HIV infection or in the treatment of AIDS.
