Authors: Ugbe, Fabian Audu; Advisor: -; Participants: Shallangwa, Gideon Adamu; Uzairu, Adamu; Abdulkadir, Ibrahim (2022) - Theoretical modeling of thirty-six arylimidamide-azole derivatives was conducted to establish a quantitative relationship between their structures and their inhibitory activities. As a result, a five-descriptor QSAR model was built (Eq. 13) with the descriptors well described in Table 4. The outcome of the internal and external validation assessment conducted on the built model is available in Table 5. The computed descriptors, observed activities (pIC50), and the predicted activities together with their residuals are presented in Table 6. Also, a plot of predicted activities versus experimental activities for the training set and test set is shown in Fig. 1, while Fig. 2 shows the plot of standardized residuals against experimental activities (pIC50).

The molecular docking and binding energy study (Figs. 2 and 3) predicted seven compounds as lead compounds that show a better inhibitory potential when compared with the standard compounds, leucovorin Calcium and Xeloda.

Authors: Isyaku, Yusuf; Advisor: -; Participants: Uzairu, Adamu; Uba, Sani; Ibrahim, Muhammad Tukur; Umar, Abdullahi Bello (2020) - A computational study was carried out on a series of twenty compounds of novel 4-(N,N-diarylmethylamines) furan-2(5H)-one derivatives against Aphis craccivora insect. Optimization of the compounds was performed with the aid of Spartan 14 software using DFT/B3LYP/6-31G** quantum mechanical method. Using PaDel descriptor software to calculate the descriptors, Generic Function Approximation (GFA) was employed to generate the model. Model 1 found to be the optimal out of four models generated which has the following statistical parameters; R2 = 0.871489, R2adj = 0.83644, cross-validated R2 = 0.790821, and external R2 = 0.550768. Molecular docking study occurred between the compounds and the complex crystal structure of the acetylcholine (protein AChBP) (PDB CODE 2zju) in which compound ...

Authors: Mahmud, Aliyu Wappah; Advisor: -; Participants: Shallangwa, Gideon Adamu; Uzairu, Adamu (2020) - Predictive and robust QSAR model was generated using Genetic Function Algorithm. The model was statistically validated to have internal and external squared correlation coefficient, R2 of 0.982 and 0.735 respectively; predictive squared correlation coefficient, R2pred of 0.599; adjusted squared correlation coefficient, Radj of 0.974; and leave-one-out cross-validation coefficient, Q2cv of 0.966. It was found out that the antiplasmodium activities of 2,5-disubstituted furans relied on the parameters: GATS5c, minsCl RDF130m, RDF75p, and RDF115s descriptors. All the descriptors except minsCl influenced the antiplasmodium activities of the compounds negatively. That is, their increase decreases the activities of the furans and vice versa. The docking study revealed that most of the fura...

Authors: Reyes-Chaparro, A.; Advisor: -; Participants: Lopez, N. S. Flores-; Guerrero, F. Quintanilla-; Nicolás-Álvarez, Dulce Estefanía; Hernandez-Martinez, A. R. (2023) - A total of 10,100 chalcone-derived molecules were obtained (Additional files 1, 2, and 3); then different screening techniques were used for physicochemical properties, molecular docking, molecular dynamics, and DFT calculations to select the best candidates. Drugs used as MAO-A inhibitors were evaluated as a reference comparison.

Authors: Adawara, Samuel Ndaghiya; Advisor: -; Participants: Shallangwa, Gideon Adamu; Mamza, Paul Andrew; Abdulkadir, Ibrahim; Abdulkadir, Ibrahim (2022) - Dengue virus (DENV) infection is spreading rapidly, especially in the subtropical and tropical regions, placing a huge percentage of the global population at risk and causing repeated outbreaks. DENV protease inhibition has been suggested as a viable therapeutic strategy. Using a computer-aided design approach and the structure-based drug design approach, ten 1, 2, 4-oxadiazole derivatives were designed based on the lead template (34) from our prior study. The design involved the substitution at the phenyl pharmacophore of the lead with methylamine, hydroxyl, and methoxy groups. To compare the anti-DENV efficacy of the optimized designed compounds to the template and other DENV referenced inhibitors targeting the NS-5 protease (PDB ID: 5K5M), they were docked with the DENV NS-5 prot...

Authors: Tukur, AbdulRazaq; Advisor: -; Participants: Habila, James Dama; Ayo, Rachael Gbekele-Oluwa; Agbeke Iyun, Ogunkemi Risikat (2022) - Antibiotic resistance has risen as a result of a variety of conditions, prompting researchers to look for new compounds that can combat multidrug-resistant organisms. Over the last two decades, chalcones have been proved to be attractive moieties in drug discovery. Various substituted acetophenones, propiophenones and 4-(Diphenylamino) benzaldehyde were combined, using the Aldol condensation reaction to obtain eight novel triphenylamine chalcones. The compound’s antimicrobial properties were investigated (in vitro). With the non-mutant X-ray Human cytochrome P450 21A2 Hydroxyprogesterone retrieved from Protein Data Bank (PDB: 5VBU), molecular docking experiments were also carried out to analyse the most favourable conformation and find the orientation that maximizes interaction and ...

Authors: Precious Ayorinde Akinnusi,; Advisor: -; Participants: Samuel Olawale Olubode,; Wasiu Adeboye Salaudeen, (2022) - The search for ideal drugs with absolute antiviral activity against SARS-CoV-2 is still in place, and attention has been recently drawn to natural products. Several molecular targets have been identified as points of therapeutic intervention. The targets used in this study include SARS-CoV-2 helicase, spike protein, RNA-dependent RNA polymerase, main protease, and human ACE-2. An integrative computer-aided approach, which includes molecular docking, pharmacophore modeling, and pharmacokinetic profiling, was employed to identify anthocyanins with robust multiple antiviral activities against these SARS-CoV-2 targets.

Authors: Abdullahi, Sagiru Hamza; Advisor: -; Participants: Uzairu, Adamu; Shallangwa, Gideon Adamu; Uba, Sani; Umar, Abdullahi Bello (2022) - In this research work Genetic function algorithm was employed to generate the QSAR models due to its ability to produce a vast population of model instead of just a single model. Four models were generated from the model building set and the first one was chosen because of its statistical significance.
