Abstract
Adipic hydrazides are very important and wide applications of nitrogen containing heterocyclic compounds, possessing broad spectrum of biological and pharmacological activities such as hypotensive1, anticancer, anti-HIV, anti-inflammatory2, analgesic, antiviral, antitubercular, antimicrobial, anti-bacterial, antipyretic, antimitotic, anticonvaulsant3, anticoagulant, anti-fibrillatory, cardiac stimulant and diuretic.4 The quinoline have been tested successfully against cancer and HIV virus.5 Their synthetic analogues possess antimalarial, hypolipidemic and antiproliferative activities6 . The coordination chemistry of adipic hydrazide ligands has received much attention because of its biological implications. 2-amino-5-iodo benzoic acid hydrazide derivatives exhibit very potent antifungal and antibacterial activities.7 These 2-amino-5-iodo benzoic acid derivatives are covered the area of biological interest of this compounds have extended recently to various microbial activities such as analgesic, diuretic, anti-inflammatory, anthelmintic, antipruritic activities8 and this class of compound showed in vitro selective anti-helicobacter pylori activity.
In view of these factors the metal complexes of the ligand L4= (N'1E, N’6E)-N1',N6’-bis ( ( 2 - hydroxyquinolin-3-yl)methylene)adipohydrazide , L5 = (N'1E, N’6E)-N'1, N’6 – bis ( ( 6-bromo-2-hydroxyquinolin-3-yl)methylene) adipohydrazide, L6= (N1 E,N6E)-N1' N6’-bis ((2-hydroxy 6-methylquinolin-3-yl)methylene)adipohydrazide.
