Synthesis, molecular modeling, DFT studies, and enantioseparation of tetrahydro-4H-chromene derivatives with calcium channel blocking activity KOÇAK ASLAN, EBRU; Karagüzel, Ayşe; Lam, Kevin; Dengiz, Çağatay; Huang, Sun; Burk, Ryan Jacob; Salehi, Reza; Sajeevan J, Siddharth Jaya; Zamponi, Gerald W.; Wolber, Gerhard; Armstrong, Daniel W.; Gündüz, Miyase Gözde (2025-05-15) Calcium channel blockers are considered effective therapeutics in cardiovascular and neurological disorders. Herein, we replaced the nitrogen atom of 1,4-dihydropyridines (DHPs), the most popular group of calcium channel b...
Enaminone-Based Push-Pull Chromophores: Synthesis, Optical Properties, and Computational Insights Mart, Mehmet; Kuyucu, Işıl Irmak; Dengiz, Çağatay (2025-04-25) Chromophores incorporating enaminone units were efficiently synthesized using click-type [2 + 2] cycloaddition-retroelectrocyclization (CA-RE) reactions. The preparation of electron-rich alkynes necessary for these reactio...
Base-Mediated Synthesis of Imidazole-Fused 1,4-Benzoxazepines via 7-exo-dig Cyclizations: Propargyl Group Transformation. Korkmaz Cokol, Nalan; İnyurt, Fevzi Can; Öktem, İpek; ŞAHİN, Ertan; Sari, Ozlem; Dengiz, Çağatay; Balci, Metin (2025-04-04) Herein, we describe the synthesis of a series of imidazole-fused 1,4-benzoxazepines using 7-exo-dig cyclizations. Two sets of substrates, one containing disubstituted alkyne functional groups and the other featuring termin...
Biginelli dihydropyrimidines and their acetylated derivatives as L-/T-type calcium channel blockers: Synthesis, enantioseparation, and molecular modeling studies GÜNDÜZ, MİYASE GÖZDE; Dengiz, Çağatay; Denzinger, Katrin; Huang, Sun; Lee, J. T.; Nafie, Jordan W.; Armstrong, Daniel W.; Wolber, Gerhard; Zamponi, Gerald W. (2025-03-01) Biginelli dihydropyrimidines (DHPMs) are considered superior over 1,4-dihydropyridines (DHPs) in terms of both light and metabolic stabilities. Nevertheless, DHPs dominate the market as the most prescribed calcium channel ...
Design and synthesis of heterocycle-based push-pull NLOphores: A comprehensive study of their linear and non-linear optical properties Karagöllü, Başak; Şengöz, Tolga Orçun; Kayaş, Hazal; Erden, Kübra; ŞAHİN, Ertan; Esentürk, Okan; Dengiz, Çağatay (2025-01-01) Push-pull chromophores, with strong intramolecular charge transfer (ICT), exhibit high ground-state polarization, driving strong NLO responses. The donor and acceptor abilities of the groups in the investigated compounds i...
Carbamate-Functionalized NLOphores via a Formal [2+2] Cycloaddition-Retroelectrocyclization Strategy Savaş, İpek; Çelik, Mehmet Efe; Barsella, Alberto; Dengiz, Çağatay (2025-01-01) This study introduces a new donor group capable of activating click-type [2+2] cycloaddition-retroelectrocyclizations, generally known for their limited scope. Target chromophores were synthesized using isocyanate-free ure...
Synthesis and Optical Characterization of Hydrazone-Substituted Push-Pull-Type NLOphores Erden, Kübra; Soyler, Dilek; Barsella, Alberto; Sahin, Onur; Soylemez, Saniye; Dengiz, Çağatay (2024-09-10) Two distinct families of NLOphores featuring hydrazone donors were synthesized using click-type [2 + 2] cycloaddition retroelectrocyclizations (CA-RE). Despite the limitations in the substrate scope, it was shown for the f...
Synthesis, molecular modeling, DFT studies, and EPR analysis of 1,4-dihydropyridines as potential calcium channel blockers KOÇAK ASLAN, EBRU; Lam, Kevin; Dengiz, Çağatay; Denzinger, Katrin; Dicle Erdamar, Isık Yesim; Huang, Sun; Zamponi, Gerald W.; Wolber, Gerhard; GÜNDÜZ, MİYASE GÖZDE (2024-07-05) 1,4-Dihydropyridines (DHPs) are widely recognized as a highly effective class of L-type calcium channel blockers that offer significant therapeutic potential in managing cardiovascular conditions. Furthermore, their abilit...
1,3‐Diynes as Precursors for the Synthesis of Triazene‐ and Diethylaniline‐Bearing Push‐Pull NLOphores Inyurt, Fevzi Can; Dengiz, Çağatay (2024-02-01) Withinthe scopeof this study,a total of eight new NLOphoresof the D-π-A-π-Dtype have been synthesized.This was achievedby applyingclick-type[2+2] cycloaddition-retroelectrocycliza-tion reactionsof unsymmetrical1,3-diyneswi...
Click-Type Synthesis of Homoconjugated Push-Pull Chromophores: Computational Investigation of Optical and Nonlinear Optical (NLO) Properties Inyurt, Fevzi Can; Mammadova, Flora; Dengiz, Çağatay (2023-1-01) Homoconjugated push-pull chromophores were obtained by an efficient, click-type formal [2+2] cycloaddition. With these short synthetic transformations, complex chromophore structures were achieved in a single step without ...
