Go to Editorial ManagerThe protective reaction of an organism to potentially harmful stimuli is known as inflammation, and it can result from a variety of sources, including physical, chemical, or viral injuries. A large number of people in our society suffer from long-term inflammatory diseases, which makes it necessary to constantly develop new anti-inflammatory drugs. The development of powerful anti-inflammatory medications has advanced significantly in recent years. As a result, heterocyclic compounds made up a sizeable fraction of organic chemistry due to their pharmacological activity and distinct physical traits that distinguished them from other cyclic compounds. One of the most common N-based heterocyclic molecules is imidazolidine. Numerous scientists have become interested in it because of the variety of industrial and pharmacological uses. In the present study, the work dedicated to designed new imidazolidine derivatives. Molecular Docking Software (Schrodinger) was used to check the binding interaction between new derivatives (4N, 4M, 4D, 4In, 4Ib) and the cyclooxygenase active site of COX-2 in comparison with naproxen, mefenamic acid, diclofenac, indomethacin and ibuprofen as references drugs respectively. The results demonstrated that good binding affinity achieved by all new compounds with the exception of 4D derivative in comparison with diclofenac. Finally, the findings of the ADME study demonstrated that all new derivatives met the Lipinski rule of five and expected to be highly absorbed from gastrointestinal tract.
Gamma-aminobutyric acid (GABA) plays a pivotal role in neuronal regulation within the Brain. This study aims to explore potential interactions between synthesized GABA derivatives and GATI through molecular docking simulations. Initially, GABA's historical significance and Therapeutic applications are outlined. The mechanism of action of GABAergic drugs and the role of GATI are elucidated. Subsequently, using ADME procedures and molecular docking protocols, the Physicochemical properties of synthesized compounds and their binding affinities to GATI are Investigated. Results reveal high gastrointestinal absorption and varying blood-brain barrier Permeability among the compounds. Docking studies show promising interactions, with compound G8 exhibiting notable affinity attributed possibly to hydrogen bond formations. This research offers Insights into potential drug development targeting GATI for modulating GABAergic signaling.
Vital cellular processes such as, proliferation and tumor progression were reported to be centrally controlled by histone deacetylase (HDAC) enzymes which make them an interesting therapeutic target. Recently, a new paradigm has attracted researches to combine nonsteroidal anti-inflammatory drugs (NSAIDs) with para-aminobenzoic acid (PABA) and a zinc binding group (ZBG), presenting a synergistic impact on HDAC activity and inflammatory process. In the current study, a novel series of hybrid compounds (A1-6) were designed and evaluated for their HDAC binding affinity by molecular docking technique along with conducting an in-silico ADME (absorption, distribution, metabolism, and elimination) profiling to assess their pharmacokinetic characteristics. Compound A6 displayed the highest binding energy score (-9.539 kcal/mol) with the active site of HDAC 8 enzyme compared with the reference ligand, SAHA (-4.606 kcal/mol). Its worth mentioning that compound A6 has comparable coordination to the catalytic zinc ion with SAHA along with engaging additional hydrophobic and aromatic interaction within the active site of HDAC 8 enzyme. ADME analysis predicated high gastrointestinal absorption for A2, A5, and A6, which also comply with Lipinski's rule, indicating good oral bioavailability. Conversely, A1, A3, and A4 showed moderate absorption, suitable for parenteral or localized/colon-targeted delivery, potentially advantageous for colon cancer treatment. These results highlight these hybrids’ potential as HDAC inhibitors and support further synthesis and biological testing.
