“…Colloidal surfactants have become one of the most important requirements in day to day life, and have great importance in modern engineering and pharmacological fields. Many copper thiosemicarbazone complexes have been found to have significant anti-tubercular, fungicidal and antitumor activities [1,2]. The use of copper linoleate as heavy duty wood preservative and many other biological activities of copper metal-containing surfactants have also been studied [3,4].…”

Background:Biologically potent compounds are one of the most important classes of materials for the upcoming generations.Objectives:Increasing number of microbial infectious diseases and resistant pathogens create a demand and urgency to develop novel, potent, safe and improved variety of antimicrobial agents.Methods:The copper surfactants substituted 2-amino-6-methyl benzothiazole were synthesized. The synthesized complexes have been characterized by IR, NMR, ESR spectroscopic methods. The antifungal activities have been evaluated by testing againstAlternaria alternatefungi. All complexes showed good antifungal activity because chelation increases the anti-microbial potency.Result:The studies suggest that the copper (II) ions in soaps may be responsible for the enhancement of the activity against fungi. The evaluation of anti -fungal studies further revealed that fungitoxicity of the complexes also depends on the nature of metal ions. The chelation reduces the polarity of central metal ion mainly because of partial attaining of its positive charge with the donor groups and possible π- electron delocalization over the whole chelate ring. Such chelation increases the lipophilic character of the central atom, which subsequently favors its permeation through the lipoid layer of the cell membrane. Their efficiency increases with their concentration.

The density, molar volume, apparent molar volume, viscosity and other parameters of Cu(II) surfactant derived from karanj oil in non-aqueous solvents of varying compositions have been determined at constant temperature 298.15 K. The results were used to determine the critical micelle concentration (CMC), soap-solvent interactions and the effect of chain length of the surface active molecule on various parameters. The CMC values of copper karanj soap solutions decreased with the increase in the concentration of polar solvent methanol in the solvent mixture. These studies were done to study the solution behaviour, micellar features and various interactions of the derived biologically active surfactant with polar and non-polar solvents to understand the applied part of the molecule. The apparent molar volume has been examined in terms of Masson equation, and the limiting apparent molar volume has been interpreted in terms of solute-solvent interaction. The detailed study of aforesaid compounds clearly indicates that the solutesolvent interaction decreases with the increase in ring strain and size of the synthesised complexes. The conclusions with regard to solute-solute and solute-solvent interaction have been discussed in terms of well-known Moulik's and Jones-Dole equations. This vital information plays an important role in the selection of the synthesised molecule for various industrial and biological applications.

“…Surface active agents are very useful in biological systems, as well as play an important role in many industrial processes [1]. Exact information about micellar feature of copper (II) surfactants play a vital role in its selection in various fields such as foaming, wetting, detergents, emulsifier, herbicides, pesticides, paints, varnishes, wood preservatives, lubricants etc [2].…”

Introduction: Biologically potent compounds are one of the most important classes of materials for the upcoming generations. Increasing number of microbial infectious diseases and resistant pathogens create a demand and urgency to develop novel, potent, safe and improved variety of antimicrobial agents. This initiates a task for current chemistry to synthesize compounds that show promising activity as therapeutic agents with lower toxicity. Therefore, a substantial research is needed for their discovery and improvement. Chemistry of present era aims to build a pollution free environment. For the same, it targets to create some alternativeswhich are eco-friendly and nature loving. Present research work is a step towards achieving such alternatives. Method: For this the metallic soaps of copper (derived from common edible oils) were synthesized. The synthesized copper soaps have been confirmed by elemental analysis, UV, and IR spectroscopic technique. The fungicidal activities of copper soaps derived from soyabean, sesame oils have been evaluated by testing against Alternaria alternate and Aspergillus niger by P.D.A. technique. Result: The fungi toxicity results indicate that the strain of fungal species are susceptible towards these soaps and suggests that with the increase in concentration of copper soap it may increase further. The transition metallic soaps showed good antifungal activity because chelation increases the anti-microbial potency.
