Publication number: 20140234429Abstract: The various embodiments herein provide super paramagnetic iron oxide nanoparticles (SPIONs). The SPIONs have a plurality of metallic coatings and plurality of polymeric gaps. The embodiments herein also provide a method of synthesizing the SPIONs with metallic rings and polymeric gaps. The metallic coatings form a ring like structure on the outer surface of the SPION. The SPION has a size of 13 nm. The ring has a thickness of 2-3 nm. The rings are one or more in number. The polymeric gaps have a thickness of 3-5 nm. The polymeric gaps are one or more in number. The method involves mixing the SPIONs with a plurality of polymers and then forming a metallic ring on the outer surface of the SPIONs. The SPIONs have anti-bacterial properties and stop a growth of bacterial biofilms. The SPIONs also have SERS properties.Type: ApplicationFiled: February 20, 2013Publication date: August 21, 2014Applicants: Pasteur Institute of IranInventors: Morteza Mahmoudi, Mohammad Ali Shokrgozar

Publication number: 20130289104Abstract: The embodiments herein provide a composition and a method of synthesizing a composition comprising an aliphatic amino acid biosynthesis inhibitor having an antifungal activity. The composition comprises 2-oxo-2H-chromen-7-yl propiolate, diethyl-hex-2-en-4-yne-dioate and dinonyl-hex-2-en-4-yne-dioate. The composition inhibits a biosynthesis of an aliphatic amino acid in a fungal biological system. The aliphatic amino acid is selected from a group consisting of leucine, isoleucine and valine. The composition is used with a concentration of 0-200 ?g/ml. The method comprises mixing solutions of dicyclohexylcarbodiimide (DCC) and Dimethylaminopyridine (DMAP) with alcohol, acetylene carboxylic acid and dichloromethane to obtain a mixture which is stirred filtered and washed with ether. The solvents are evaporated to obtain a residue that is dissolved in dichloromethane and stirred with a catalyst. The extra solvents are evaporated to obtain the derivative compound and purified by silica gel column chromatography.Type: ApplicationFiled: June 17, 2012Publication date: October 31, 2013Applicants: Pasteur Institute of IranInventors: Soroush Sardari, Vahid Khalaj, Mahdieh Mahboobi Khomeini, Parisa Azerang
