    THE ANTIPROLIFERATIVE, ANTIOXIDANT ACTIVITIES AND TOXICITY OF MIXED-LIGAND AMINE-CONTAIN- ING COPPER(II) COORDINATION COMPOUNDS WITH 2-(2-HYDROXYBENZYLIDENE)-N-(PROP-2-EN-1-YL)HY- DRAZINECARBOTHIOAMIDE
    (2021-09-16) Garbuz, Olga; Toderaș, Ion; Ulchina, Ianina; Graur, Vasile; Railean, Nadejda; Gulea, Aurelian
    Five compounds 2-(2-Hydroxybenzylidene)-N-(prop-2-en1-yl)hydrazinecarbothioamide (H2L), bis[μ2-2-({2-[(prop-2-en-1-yl) carbamothioyl] hydrazinylidene}methyl) phenolatoS,N,O:O] diaquadicopper (II) nitrate (1), bis [μ2-2-({2-[(prop-2-en-1-yl) carbamothioyl] hydrazinylidene}methyl)phenolato-S,N,O:O]d iimidazoldicopper(II) nitrate (2), bis[μ2-2-({2-[(prop-2en-1-yl)carbamothioyl]-hydrazinylidene}methyl)phenolato-S,N,O:O]bis-(3,5-dibromopyridine)dicopper( II) nitrate hexahydrate (3), bis[μ2-2-({2-[(prop-2-en-1-yl)carbamothioyl]-hydrazinylidene}methyl) phenolato-S,N,O:O]bis(4-methylpyridine)dicopper(II) nitrate hexahydrate (4) were synthesized. The antiproliferative properties of these compounds towards cancer cell lines HeLa, RD and normal cell line MDCK have been investigated. The tested compounds demonstrated high antioxidant and antiproliferative, selective activities towards cancer cells. Direct toxic evaluation of compounds was performed by Daphnia magna bioassay.

    EVALUAREA BIOLOGICĂ A COMPUȘI LOR COORDINATIVI AI CUPRULUI(II) CU UNELE TIOSEMICARBAZONE HETEROCICLICE
    (CEP USM, 2022) Garbuz, Olga; Railean, Nadejda; Gostev, Igor; Rusnac, Anna; Toderaş, Ion; Gulea, Aurelian
    Au fost sintetizați 3 compuși noi: tiosemicarbazona 2-acetilpiridinei H2L, cloro(tiosemicarbazona-2-acetilpiridinei) cupru(II) (1) și nitrato(tiosemicarbazona-2-acetilpiridinei)cupru(II) (2) care potențial posedă proprietăți antiproliferative fată de celulele canceroase. Doxorubicina (7-[4-amino-5-hidroxi-6-metiloxan-2-il]oxi-6,9,11-trihidroxi-9-(2-hidroxiacetil)4-metoxi-8,10-dihidro-7H-tetracen-5,12-dionă) a fost utilizată în calitate de compus anticancerigen de referință și Trolox (acid 6-hidroxi-2,5,7,8-tetramethilcroman-2-carboxilic) a fost utilizat ca compus antioxidant de referință. Compușii testați au demonstrat efect antioxidant înalt față de cationii radicali ABTS•+ în comparație cu interacțiunea acestor cationi cu Trolox. Compușii testați au manifestat toxicitate generală față de Daphnia magna după 24 de ore de expunere cu determinarea unui șir de descreștere. Datele experimentale au indicat perspectivele pentru viitoare căutări ale substanțelor anticancerigene selective cu acțiune antioxidantă înaltă și toxicitate scăzută.
