Abstract

본 연구에서는 Benzanthrone 치환체인 3-N-2-hydroxy ethylamine benzanthrone (HEAB)와 3-N-2-amino ethylamine benzanthrone (AEAB)의 Cu(II), Co(II) 및 Ni(II) 염화물 착물에 대한 분광학 (IR, UV-vis 및 <TEX>$^1H$</TEX>-NMR), 원소분석, 몰전도도, 열무게분석 (TGA/DTG) 및 생물학적 특성에 대해 고찰하였다. 이 연구의 결과에서 HEAB리간드가 히드록소 및 아미노기를 통하여 각 금속에 배위되어 [Cu(HEAB)<TEX>$(Cl)_2$</TEX>].<TEX>$2H_2O$</TEX>, [Co(HEAB)<TEX>$(Cl)_2(H_2O)_2$</TEX>].<TEX>$8H_2O$</TEX> 및 [Ni(HEAB)<TEX>$(Cl)_2(H_2O)_2$</TEX>].<TEX>$7H_2O$</TEX> 착물을 형성함을 알았다. 한편, AEAB는 [Cu(HEAB)<TEX>$(Cl)_2$</TEX>].<TEX>$2H_2O$</TEX>, [Co(HEAB)<TEX>$(Cl)_2(H_2O)_2$</TEX>].<TEX>$8H_2O$</TEX> 및 [Ni(HEAB)<TEX>$(Cl)_2(H_2O)_2$</TEX>].<TEX>$7H_2O$</TEX>의 분자식을 갖는 팔면체 배위구조를 갖는다. <TEX>$25^{\circ}C$</TEX> DMF에서 모든 착물의 몰전기전도도는 반응안한 리간드보다 약간 컸는데, 이는 염화 이온이 배위권 내부에 존재함을 의미한다. Benzanthrone계 리간드와 이들 착물을 이용하여 서로 다른 종류의 박테리아에 대한 생물활성을 조사하였다. Spectroscopic (infrared, electronic and <TEX>$1^H$</TEX>-NMR), elemental analyses CHN, molar conductivity, thermogravimetric analyses (TGA/DTG) and biological studies, of both benzanthrone derivatives 3-N-2-hydroxy ethylamine benzanthrone (HEAB) and 3-N-2-amino ethylamine benzanthrone (AEAB) with Cu(II), Co(II) and Ni(II) chlorides were discussed herein. Based on the above studies, HEAB ligand was suggested to be coordinated to each metal ions via hydroxo and amino groups to form [Cu(HEAB)<TEX>$(Cl)_2$</TEX>].<TEX>$2H_2O$</TEX>, [Co(HEAB)<TEX>$(Cl)_2(H_2O)_2$</TEX>].<TEX>$8H_2O$</TEX> and [Ni(HEAB)<TEX>$(Cl)_2(H_2O)_2$</TEX>].<TEX>$7H_2O$</TEX> coordinated complex. On the other hand, AEAB has an octahedral coordinated feature with formulas [Cu(AEAB)<TEX>$(Cl)_2(H_2O)_2$</TEX>].<TEX>$2H_2O$</TEX>, [Co(AEAB)<TEX>$(Cl)_2(H_2O)_2$</TEX>].<TEX>$4H_2O$</TEX> and [Ni(AEAB)<TEX>$(Cl)_2(H_2O)_2$</TEX>]. <TEX>$6H_2O$</TEX>. The molar conductance values at <TEX>$25{\circ}C$</TEX> for all complexes in DMF are slightly higher than free ligands; this supported the presence of chloride ions inside the coordination sphere. Both benzanthrone ligands and their complexes have been screened against different kinds of bacteria.
