measurement of pH, conductivity, viscosity, antifungal activity, drug release kinetics. Miconazole nitrate cream (2%) was used as reference sample for comparison of antifungal activity and release rate. The data obtained from various studies gave satisfactory results. Therapeutic compounds can be derived from various natural sources like plants, animals, marine organisms, and microorganisms. Although the marine biota accounts for around 50% of the total world biodiversity, but their potential as a rich source of bioactive products and their applications in both pharmaceutical and nutraceutical industries have only recently been identified through several Author: Charu Gupta, Dhan Prakash. Fitting structure with R', R H and R C6H4Cl or C6H,4Cl2 produces compounds with moderate antifungal activity. However from similar series, compounds with R Me3C-, R' 2,4-Cl2C6H3CH2-, and R H show strong inhibition of Staphylococcus aureus and Trichophyton mentagrophytes. One other example of compounds with Az Tr, R 2-(4 /5.

Aspergillus spp. produce a wide variety of diseases. For the treatment of such infections, the azoles and Amphotericin B are used in various formulations. The treatment of fungal diseases is often ineffective, because of increases in azole resistance and their several associated adverse effects. To overcome these problems, natural products and their derivatives are interesting by:

The antimicrobial and antifungal activity of the phenolic extract from these plants (leaves) was also compared with the Triclosan. Triclosan is a chlorinated aromatic compound with antibacterial, antifungal and antiviral properties.
The Triclosan is used in a variety of common household and personal care products, including soaps, mouthwashes. A series of novel 3-substituted coumarinyl-triazine derivatives were designed and synthesized from 3-carboxycoumarins via consecutive Knoevenagel and Pinner reactions in water.

Following the observation that the antifungal agent ketoeonazole was teratogenic in rats (Symoens and Cauwenbergh ), we identified the triazole antifungal ICIalso as a teratogen in the rat (Flint and Boyle ).In an effort to elucidate structure-activity relationships, we tested 16 further monotriazoles for in vitro antifungal activity and for toxicity using a simple Cited by: 6.
In these natural sources, a series of molecules with antifungal activity against different strains of fungus have been found, which are of great importance to humans and plants. In this article, we review the main sources of molecules with antimycotic activity obtained from.
TLC separation and subsequent testing of antifungal activity have been worked out for essential oils and plant extracts and led to the identification of potent anti-candidal compounds (22,39,45).
This method avoids the need of previous purification of the substances, reducing the costs of the initial screening. For instance, halogen-substituted phenols induced bifurcations of the tail in embryos exposed in vitro, but no tail malformations were seen for this subset in vivo In addition to structure-activity relationships in vitro, further studies have been undertaken to construct structure-dosimetry relationships for the phenols Preliminary results suggest that the more lipophilic phenols are largely bound by macromolecules in Cited by: 7.
