Abstract :Non-steroidal anti-inflammatory drugs insert ignore into journalissuearticles values(NSAIDs); and anti-hypertensive drugs have been in use for a long time for the treatment of inflammation, pain, hypertension. Besides these functions, they also show different types of other activities. Many of them exhibit critical side effects in different types of cancer such as colon, lung and breast cancer. In the present study, we computationally investigated the interactions of some nonsteroidal anti-inflammatory and anti-hypertensive drugs insert ignore into journalissuearticles values(acebutolol, naproxen, diflunisal, bisoprolol); with nucleobases insert ignore into journalissuearticles values(A, C, G, T); by employing several DFT functionals namely B3LYP, B3LYP-D2 and ωB97X-D. The main purpose of this study is was to determine the strengths of drug-DNA-base interactions that can provide insights about the side effects of the drugs. The calculations were produced the following results. Acebutolol has the highest interaction between adenine in single base-drug complexes. However, acebutolol has the strongest interaction between the guanine-cytosine base pair. The ωB97X-D method, which accounts for dispersion interaction properly, gives better results than the B3LYP and B3LYP-D2 methods.
