    Adsorption of Eriochrome Black T on the chitin surface: Experimental study, DFT calculations and molecular dynamics simulation
    (Elsevier, 2021) Serdaroğlu, Goncagül
    In this study, chitinwith highmolecularweightwas extracted fromshrimp shells and characterized by XRD, FTIR, and SEM. The solid was investigated in Eriochrome black T dye (EB) adsorption in aqueous solution. Experimental results indicated high EB uptake in acidic medium with maximum adsorption capacity of 167.31 mg/g. The kinetics of adsorption followed pseudo-second-order kinetic model and equilibrium data fitted well Langmuir model suggesting a suitable chemisorption process. The thermodynamic parameters showed a spontaneous and exothermic process with favorable adsorption at a relatively low temperature. The molecular dynamics (MD) simulation confirms the chemical adsorption capability of the EB on the (110) surface of the biopolymer. Moreover, density functional theory (DFT) calculations were carried out to understand the experimental behavior. The order of the interaction energies calculated for the complexes indicates that the best and possible adsorption process can take place with the anionic H2EB− form of the dye. The deformation energies indicates that the conformational re-arrangement makes both the EB and chitin surface less stable which supported the experiment and quantum chemical analyses. This result also demonstrates the accuracy and feasibility of the MD simulation to study the adsorption mechanism.

    (Elsevier B.V., 2025) Serdaroğlu, Goncagül; Uludag, Nesimi; Serin, Sümeyya
    A new entry into the synthesis of tetrahydroindeno[1,2-d]imidazole compounds 4a-c is based on the reactions isothiocyanate benzene 1 and substituted aniline 2 via condensation with 1H-indene-1,2,3-trione in a one-pot three-component. A wide variety of relevant tetrahydroindeno[1,2-d]imidazole derivatives were obtained with high yields ranging from 97 to 98 % with excellent yields. The synthesized compounds were determined using FT-IR, 1H NMR, 13C NMR, and elemental analysis methods. Moreover, the DFT calculations performed on 4a-c provide additional validations to the experimentally obtained data of the compounds, as well as useful insights on topics such as reactivity trends and physicochemical properties. In this context, in the initial stage, the conformational study was performed and minimum energy structures were determined for 4a-c. The subsequent stage included a comparative analysis of the electronic properties, reactivity tendencies, possible donor–acceptor interactions, and electrostatic surface properties of the mentioned compounds in gas, CHCl3, and DMSO environments. All FT-IR and NMR computations were performed at B3LYP/6–311++G** level for confirmation purposes. The ADMET “Adsorption-Distribution-Metabolism-Excretion-Toxicity”, drug-likeness, and physicochemical characteristics of compounds were evaluated to explore possible suitability for early-stage-drug-design research. © 2025 Elsevier B.V.

    A combined molecular dynamic simulation, DFT calculations, and experimental study of the eriochrome black T dye adsorption onto chitosan in aqueous solutions
    (Elsevier, 2021) Serdaroğlu, Goncagül
    This study aims to evaluate and understand the adsorption of eriochrome black T (EB) by chitosan extracted from local shrimp shells under different experimental conditions. Chitosan samples were characterized by XRD, SEM, and FTIR. Experimental results indicate that the process was pH-dependent with a high adsorption capacity in acidic medium. The adsorption was rapid and kinetic data were suitably correlated to the pseudo-secondorder kinetic model. EB molecules were adsorbed on monolayer according to the Langmuir model with an adsorption capacity of 162.3mg/g. On the other hand, it should be noted that calculated quantumchemical parameters support the experimentally obtained results. The interaction energies calculated for (molecule/chitosan) complexes were in the order of H2EB− > HEB2− (O38) > HEB2− (O48) > EB > H3EB > EB3−, which means that the best and possible adsorption process can take placewith H2EB− form. The molecular dynamics (MD) approachwas performed to illuminate the nature of the relationship between the EB and the chitosan (110) surface. Itwas found that the chitosan (110) surface adsorbs EB molecule in a nearby parallel orientation. The higher negative adsorption energy determined for the H2EB− implies that the adsorption mechanism is the typical chemisorption.

    Seven novel Cu(II) complexes [Cu(HPySc)Cl 2 ] ( 1 ), [Cu 2 (PySc) 2 (NO 3 ) 2 ] ·H 2 O ( 2 ), [Cu(HPySc)(SO 4 )] ·½H 2 O ( 3 ), [Cu 2 (PySc) 2 (OAc) 2 ] ·CH 3 OH ( 4 ), [Cu 2 (PySc) 2 Br 2 ] ·H 2 O ( 5 ), [Cu(PySc)(NCS)] ·2H 2 O ( 6 ) and [Cu 2 (PySc) 2 (N 3 ) 2 ] ( 7 ) with 2-pyridinecarboxaldehyde-N 4 -phenylsemicarbazone (HPySc) have been prepared and character- ized using different analytical and spectroscopic techniques. The complex 6 is expected to be square planar while the other complexes are expected to be square pyramidal arrangement, among these, the geometry of complex 4 has been conformed by single crystal XRD study that it is a dimer and adopts distorted square pyramidal geometry around copper(II) centre. All the complexes are found to be para- magnetic and non-conductive in nature. The semicarbazone ligand is coordinated in neutral form in two of the complexes and in ionic form in others. DFT/B3LYP/6-311g ∗∗/LANL2DZ computations of the ligand HpySc (PyCHNNCONHPh) and seven Cu(II) complexes were performed to analyze the FMOs and impor- tant electron delocalizations that existed in each compound. Molecular stability and bond strengths have been investigated by applying natural bond orbital (NBO) analysis. All the complexes are more stable than the semicarbazone and the complex 2 is the most electronically stable (-5.160 eV) among the com- plexes. Furthermore, the semicarbazone is the hardest and complex 5 is the softest than all complexes due to the ηvalues. The calculated energy gap between HOMO and LUMO energies show the variations of nucleophilic and electrophilic reactivity regions in the semicarbazone and in complexes 1-7 .

    Equilibrium, Thermodynamic, and Density Functional Theory Modeling Studies for the Removal of Dichromate Ions from Wastewater Using Calix[4]arene Modified Silica Resin
    (ACS, 2021) Junejo, Ranjhan; Jalbani, Nida Shams; Memon, Shahabuddin; Kaya Savaş; Erkan Sultan; Serdaroğlu, Goncagül; Palabiyik, Ismail Murat
    Water is contaminated by different toxicants such as anions, cations, and organic waste products. In this regard, this study reveals the removal of Cr2O7 ions from water using calix[4]arene modified silica (CMS) resin under the optimized conditions of concentration, pH, resin dosage, and effects of temperature. During the experiments, it was noticed that the adsorption of Cr2O7 ions onto CMS resin is highly pH-dependent and has high adsorption capacity using only 25 mg of resin. The adsorption equilibrium data have been subjected to different isotherm models such as Langmuir, Freundlich, and Dubinin–Radushkevich (D-R). From the results, it has been observed that the Freundlich model is the best fit for an adsorption phenomenon as compared to the Langmuir model, while the D-R model demonstrates that the adsorption is an ion exchange type according to the values of E (kJ/mol). The thermodynamic study reveals that the values of ΔH, ΔG, and ΔS show that the adsorption process is endothermic and spontaneous. Dichromic acid (H2Cr2O7) and its conjugated base (Cr2O72– anion) were optimized at the B3LYP/LANL2DZ/6-311++G(d,p) level by using G09W software to analyze the adsorbate-adsorbent interaction mechanism. The efficiency and adsorption capacity of CMS resin have also been checked on real wastewater collected samples.

    New Hybrid (E)-4-((pyren-1-ylmethylene)amino)-N-(thiazol- 2-yl)benzenesulfonamide as a Potential Drug Candidate: Spectroscopy, TD-DFT, NBO, FMO, and MEP Studies
    (Wiley, 2021) Serdaroğlu, Goncagül
    A novel pyrene-sulfathiazole-based potential drug candidate 3 was designed, successfully synthesized by a condensation reaction of pyrenecarboxaldehyde (1) with sulfathiazole (2) in good yield, and fully characterized by NMR, IR, UV-Vis, and HRMS spectroscopic techniques. The TD-DFT/B3LYP calculations displayed that the recorded peaks at 396, 377, 280, and 236 nm were due to the mainly n-π* and partially π-π* transitions that occurred on pyrene, azomethine, and sulfathiazole moieties. The NBO results disclosed that the electron delocalizations happened onto sulfathiazole, aromatic rings (pyrene and Ph-), and azomethine groups had the main responsibility of the lowering stabilization energy of compound 3. The NMR shifts were calculated by using the GIAO approaches in the DMSO phase and compared with the relevant data recorded. The thermodynamic and quantum chemical quantities were used for elucidating the physicochemical properties and reactivity behavior, in THF, DMSO, and water simulation environments. Accordingly, the calculated DM (D) and α (au) order of compound 3 were calculated in the order of vacuum

    Novel Ag(I)-NHC complex: synthesis, in vitro cytotoxic activity, molecular docking, and quantum chemical studies
    (2022) Serdaroğlu, Goncagül; Şahin, Neslihan; Şahin-Bölükbaşı, Serap; Üstün, Elvan
    The importance of organometallic complexes in cancer biology has attracted attention in recent years. In this paper, we look for the in vitro cytotoxic capability of novel benzimidazole-based N-heterocyclic carbene (NHC) precursor (1) and its Ag(I)-NHC complex (2). For this purpose, these novel Ag(I)-NHC complex (2) was characterized by spectroscopic techniques (1H, 13C{1H} nuclear magnetic resonance (NMR), and Fourier-transform infrared spectroscopy (FT-IR)). Then, in vitro cytotoxic activities of NHC precursor (1) and Ag(I)-NHC complex (2) were investigated against MCF-7, MDA-MB-231 human breast, DU-145 prostate cancer cells, and L-929 healthy cells using MTT assay for 24, 48, and 72 h incubation times. Ag(I)-NHC complex (2) showed promising in vitro cytotoxic activity against all cell lines for three incubation times, with IC50 values lower than 5 μM. It was also determined that (NHC) precursor (1) were lower in vitro cytotoxic activity than Ag(I)-NHC complex (2) against all cell lines. Selectivity indexes (SIs) of Ag(I)-NHC complex (2) against cancer cells were found higher than 2 for 24 and 48 h incubation time. Besides, the electronic structure and spectroscopic data of the newly synthesized precursor and its Ag-complex have been supported by density functional theory (DFT) calculations and molecular docking analysis. After, the anticancer activity of these compounds has been discussed considering the results of the frontier molecular orbital analysis. We hope that the obtained results from the experiments and computational tools will bring a new perspective to cancer research in terms of supported by quantum chemical calculations.

    Organic and inorganic corrosion inhibitors: A comparison
    (wiley, 2021) Serdaroğlu, Goncagül; Kaya, Savaş
    Organic and inorganic compounds are widely used as corrosion inhibitors. It is important to mention that most of the inorganic compounds are toxic and non-environmental friendly; therefore, their current use as corrosion inhibitors is strictly inhibited because of the increasing ecological awareness and strict environmental regulations. Most of the organic compounds become effective by adsorbing on the metallic surface. Adsorption of the organic compounds mostly follows the Langmuir adsorption isotherm model. Polar functional groups and multiple bonds act as adsorption centers during the metal inhibitor interactions. Present chapter deals with the comparison of various aspects of corrosion inhibition using organic and inorganic corrosion inhibitors. © 2022 John Wiley & Sons, Inc.

    PEPPSI type complexes: Synthesis, x-ray structures, spectral studies, molecular docking and theoretical investigations
    (2021) Serdaroğlu, Goncagül; Şahin, Neslihan; Üstün, Elvan; Tahir, Muhammad Nawaz; Arıcı, Cengiz; Gürbüz, Nevin; Özdemir, İsmail
    In this work, three novel potent benzimidazolium-derived PEPPSI type palladium complexes, namely dichloro[1-allyl-3-benzylbenzimidazole-2-ylidene]pyridine palladium(II) (1), dichloro[1-allyl-3-(1- naphthylmethyl)benzimidazole-2-ylidene]pyridine palladium(II) (2) and dichloro[1-allyl-3-(9-anthrylmethyl) benzimidazole-2-ylidene]pyridine palladium(II) (3), were synthesized and characterized by single X-ray crystallography, FT-IR and NMR spectroscopy. The results were compared with the relevant calculated data. After structural and spectroscopic determination, the performance of the global reactivity behavior of these derivatives was evaluated by quantum chemical parameters (QCP) obtained from DFT/B3LYP and HF methods utilized with the 6–311 g**/LANL2DZ basis set. Next, NBO analyses were conducted to enlighten the possible interactions that occur for each derivative and this revealed that the main role in the lowering of the stabilization energies of all the derivatives was sourced from n ? p* and p ? p* interactions. Finally, all the complexes were analyzed for their anticancer potential by the molecular docking method with VEGFR (vascular endothelial growth factor receptor), thioredoxin reductase, breast cancer and the dodecamer structure of DNA.
