Fungicidal Activities and Characterization of Novel Biodegradable Cu (II) Surfactants Derived from Lauric Acid

Abstract

Introduction: Colloidal systems are extremely widespread in nature and are of great practical importance in our daily life. Surfactants are very important in modern engineering and pharmaceutical soap and the complexes of soaps with different ligands are used in almost all sectors of national economy due to the formation of micelles in solutions and high surface activity i.e. the ability of their molecules to form surface adsorption layers. For this purpose, first time we thought about the synthesis of copper surfactants/soaps and their complexation by N/S donor ligands. Methods and Materials: In this paper, we report the synthesis of copper laurate thiourea by conventional methods and its characterization by elemental analysis, IR, NMR, ESR spectral studies. In order to understand their biological aspects and application of these surfactants/complexes as antifungal agents, astudy has also been conducted in the field of biochemistry. In order to understand their biological aspects with special reference to fungicidal activities, three different fungi namely Aspergillus alternaria, Aspergillus Fumigatus and Aspergillus niger were taken and tested by different concentrations of copper laurate soap and its thiourea complex by P.D.A. (Potato dextrose agar) technique. Conclusion: Biological studies of these compounds will also provide an important account of information about their industrial utilization.

Synthesis, Characterization and Biological Analysis of Some Novel Complexes of Phenyl Thiourea Derivatives with Copper

“…The descriptive statics results of all complexes also confirm satisfactory results in triplet [32]. This work also coincided with Sharma et al [33], Mathur et al [34], Bhutra el al. [35] on fungicidal activities of copper surfactants derived from lauric acid, substituted complex of benzothiazole of copper palmitic acid and copper surfactants derived from fried oils treated and untreated at higher temperatures, respectively.…”

Surface Active Properties and Micellar Features of Copper Soaps Derived from Various Edible Oils

“…The plots of fluidity ϕ against soap concentration (c) show an abrupt change at a point corresponding to the CMC of the soap Fig. (2). A perusal of the CMC data shows that it is dependent on the solvent composition and values are in good agreement with the values obtained from η v/s c, and η sp v/s c plots.…”

“…Surface-active agents are vital components in biological systems and play an important role in many industrial processes because of their ability to lower interfacial tension [1,2]. Although the use of surfactants in preservation of wood, water proofing and repellency, protection of crops, stabilization of nylon threads, lubrication etc.…”

Synthesis, Spectral and Thermo-Gravimetric Analysis of Novel Macromolecular Organo-Copper Surfactants

“…Recently, work on poly-metallic complexes and transition metal complexes of heterocyclic ligands has been done; and their structure and biological characteristics have also been discussed [4]. Various workers have studied different spectral technique like IR, ESR, NMR and magnetic moment studies of various complexes containing Copper soaps to determine their geometrical and structural aspects [5,6]. Neem (Azadirectaindica) and karanj (Pongamia pinnata) are very good for Anthelmintic (parasites and works), and anti-inflammatory properties [7].The most characteristic property of amphipilic molecules is the capacity to aggregate in solutions.…”
