The aim of our study was the toxicological evaluation of the drug Dermadex, which is a new medicinal form of the antifungal agent 2-mercantobenzothiazole, as well as the study of its fungicidal and fungistatic activity with the development of tactics for the treatment of microsporia and trichophytia.

Ketoconazole (Nizoral - Janssen) is a new antifungal agent. Like the other imidazoles with antifungal activity such as miconazole,1 clotrimazole2 and econazole,3 it acts by inhibiting fungal cell-membrane synthesis.4 It is well absorbed and exerts a systemic effect; it is thus suitable for oral administration.

A novel zinc chelate of 3-cyano-4,6-dimethyl-2(1H)-selenone pyridine was synthesized and its structure was confirmed on the basis IR, 1H NMR, 13C NMR spectral analyses and TOF mass spectrometry. Biological screening against Candida glabrata reveals a greater antifungal activity of the zinc chelate as compared to the fluconazole reference drug.

ABSTRACT: Development of more effective and less toxic antifungal agents is required for the treatment of various fungal disease.Plants and their extraction preparation have beenused as medicine against infectious diseases.The present study was aimed to study, the antifungal activity of the seeds of various seed abstract of plant Malva Parviflora (Linn). The antifungal activity of seeds extract of plant was determine by using agar well diffusion method,MIC(minimum inhibitoryconcentration) and MFC (minimum fungicidal count)by using micro dilution method . The seeds extract of the plant were examined using Methanol, Ethyl acetate ,Petroleum ether and water as solvent and tested against different fungi pathogens. From the result it can be concluded that the all the seeds extract shows the significant activity against the micro organism, hence these extract may be used as a source of antifungal agent obtained from herbal medicine and may be explore as new and effective antifungal agent. Various solvent extracts of the plant Malva parvifiora (Linn) have been found to possess enough antibacterial activity and may potentially be explored as human antifungal agent.

To minimize the intrinsic toxicity of the antibacterial agent hydrazinyloxadiazole 1, the hydrazine moiety was replaced with ethylenediamine (compound 7). This replacement generated a potent antifungal agent with no antibacterial activity. Notably, use of a 1,2-diaminocyclohexane moiety, as a conformationally-restricted isostere for ethylenediamine, potentiated the antifungal activity in both the cis and trans forms of N-(5-(2-([1,1’-biphenyl]-4-yl)-4-methylthiazol-5-yl)-1,3,4-oxadiazol-2-yl)cyclohexane-1,2-diamine (compounds 16 and 17). Both compounds 16 and 17 were void of any antibacterial activity; nonetheless, they showed equipotent antifungal activity in vitro to that of the most potent approved antifungal agent, amphotericin B. The promising antifungal effects of compounds 16 and 17 were maintained when assessed against an additional panel of 26 yeast and mold clinical isolates, including the Candida auris and C. krusei. Furthermore, compound 17 showed superior activity to amphotericin B in vitro against Candida glabrata and Cryptococcus gattii. Additionally, neither compound inhibited the normal human microbiota, and both possessed excellent safety profiles and were 16 times more tolerable than amphotericin B.

Aqueous extract of Urginea indica kunth. (Udupi acccession) was screened for antifungal activity against Fusarium oxysporum, Sclerotium rolfsii, Magnaporthe orzae, Aspergillus flavus, Alternaria alternata, Aspergillus niger and Fusarium moniliformae by poisoned food technique. The results confirmed Urginea indica extracts showed very significant antifungal activity against Fusarium oxysporum and showed significant inhibition for Sclerotium rolfsii and Magnapothea orzaea it showed no activity against Aspergillus niger and Aspergillus flavus. All the activity was evaluated to determine the lowest concentration required to inhibit visible mycelial growth of the pathogen at minmum concentration. Fusarium oxysporum showed very significant inhibition in 10% concentration (Reconfirmed) while Sclerotium showed significant inhibition in 25% concentration followed by Magnoporthe oryzae. The number of sclerotia spores formed was also reduced drastically. These results show that a potential and safe antifungal agent can be obtained from Urginea.
