N,N'-Bis[1-aryl-3-pyrrolidine-1-yl)propylidene]hydrazine dihydrochlorides (R1-R7) were synthesized by the reaction of 2 mols of 1-aryl-3-(pyrrolidine-1-yl)-1-propanone hydrochlorides with 1 mol of hydrazine hydrate and reported for the first time with their detailed spectral analysis and cytotoxicities towards human hepatoma (Huh7) and breast cancer (T47D) cell lines. Compounds R2, R6, and R7 with the IC50 values of 5.16, 6.96, and 5.96 mu M, respectively, showed higher cytotoxic potency than the reference compound 5-FU with 7.0 mu M against Huh7 cell line. However, all compounds did not show better cytotoxic activities than 5-FU against T47D cell line at the conditions studied. The representative compound of series, R2, inhibited the mitochondrial respiration at 90, 165, and 265 mu M concentrations in a dose dependent manner in liver homogenates, suggesting that mitochondrial respiration may be one of the contributing factor to the cytotoxicity of the compounds synthesized. The compounds R2, R6, and R7 can be chosen as the leader compounds of this study for further studies.

Mitochondria-Targeting Selenophene-Modified BODIPY-Based Photosensitizers for the Treatment of Hypoxic Cancer Cells Karaman, Osman; Almammadov, Toghrul; Gedik, M. Emre; GÜNAYDIN, GÜRCAN; Kolemen, Safacan; Günbaş, Emrullah Görkem (Wiley, 2019-11-05) Two red-absorbing, water-soluble and mitochondria (MT)-targeting selenophene-substituted BODIPY-based photosensitizers (PSs) were realized (BOD-Se, BOD-Se-I), and their potential as photodynamic therapy (PDT) agents were evaluated. BOD-Se-I showed higher O-1(2) generation yield thanks to the enhanced heavy-atom effect, and this derivative was further tested in detail in cell culture studies under both normoxic and hypoxic conditions. BOD-Se-I not only effectively functioned under hypoxic conditions, but als...
Fam-zinc catalyzed asymmetric 1,3-dipolar cycloaddition reactions of azomethine ylides and Koyuncu, Hasan; Doğan, Özdemir; Department of Chemistry (2007) In the first part of this study, four new chiral ligands (FAM) were synthesized and used in catalytic amounts in asymmetric 1,3-dipolar cycloaddition reactions of azomethine ylides. This method leads to the synthesis of chiral pyrrolidines, which are found in the structure of many biologically active natural compounds and drugs. It was found that using 10 mol% of one of these chiral ligands with different dipolarophiles (dimethyl maleate, dimethyl fumarate, methyl acrylate, tert-butyl acrylate, and Nmethylm...
Mechanistic Insights into the Reaction of N-Propargylated Pyrrole- and Indole-Carbaldehyde with Ammonia, Alkyl Amines, and Branched Amines: A Synthetic and Theoretical Investigation Sari, Ozlem; Seybek, Ali Fatih; Kaya, Serap; Menges, Nurettin; ERDEM, SAFİYE; BALCI, METİN (Wiley, 2019-09-01) The reaction of pyrrole- and indole-carbaldehydes having a propargyl group attached to the nitrogen atom with various amines was studied. The reaction with ammonia formed pyrrolo[1,2-a]pyrazine and pyrazino[1,2-a]indole while the reaction with alkylamines such as methyl, ethyl, hexyl, and benzylamines formed the corresponding pyrazinone derivatives. Unexpectedly, the reaction with allylamine and propargylamine formed pyrazine derivatives in which the allyl and propargyl groups were removed from the molecule...
Chemoenzymatic synthesis of chiral hydroxymethyl cycloalkenols Şenocak, Deniz; Demir, Ayhan Sıtkı; Department of Chemistry (2004) Chiral cyclic alkenols with hydroxymethyl functionality are important structural units in many biologically active natural compouds such as prostaglandins, sesquiterpene antiviral agents, pentenomycins, xanthocidin, sarkomycin, etc. 1,3-cycloalkanediones are converted into bicyclic polyoxo derivatives with formaldehyde and trioxane in the presence of Lewis acid. Selective oxidation of the bicyclic compounds by using manganese(III)acetate followed by enzyme-catalyzed kinetic resolution afforded chiral bicycl...
Cettaertalyst-Free Hydrogenation of Alkenes and Alkynes with Hydrazine in the Presence of Oxygen Menges, Nurettin; Balcı, Metin (Georg Thieme Verlag KG, 2014-03-17) A series of alkenes and alkynes was subjected to reduction with hydrazine hydrate in ethanol in the presence of oxygen. An efficient method was developed for the reduction of C-C double bonds and C-C triple bonds with diimide, generated in situ from hydrazine hydrate by oxidation with oxygen. The reduction process proceeded for 24-48 hours with high chemoselectivity and excellent yields. This reduction procedure offers synthetic advantages over metal-catalyzed hydrogenation as well as other systems.
