Fungistatic activity

Test Method. There are several standard methods available to investigate the fungistatic activity of plastic materials (e.g. ISO 846, ASTM G21, ASTM E 1428). In the given study a method has been used which is not yet a standard test method but which is at the moment passing through the official procedure to become an ISO standard The NS A method. 

To demonstrate the fungistatic activity in another type of plastic polyurethane foams, equipped with different concentrations of OIT, have been investigated. Results of the NSA test on those samples are listed in table 2. 

Nielson125 reports the synthesis of 7-((V-aIkylamino)- and T-(N,N-di-alkylamino)-l,3,5-triazaadamantanes by reductive alkylation of 94, which is obtained from 91 by an improved hydrogenation procedure (rhodium-charcoal catalyst, 25.5 psi). Paper chromatography54 and the Kovats indices and relative elution volumes of 1,3,5-triazaadamantane derivatives are measured.55 7-Amino-l,3,5-triazaadamantane is used as a vulcanization accelerator.127 7-(N,N-Dialkylamino)-l,3,5-triazaadamantanes are utilized as a new class of high-density fuel (DIADAM).128 Some 7-substituted 1,3,5-triazaadamantanes have bacteriostatic and fungistatic activity.129 7-Bromo-,... 

An extract taken from the composted straw of the alkaloid-rich lupin plants has produced very promising results in the development of biological control agents. The fungistatic activity of straw compost extracts increased markedly when the lupin straw used for composting was enriched with alkaloid extract.

Azole antifungal drugs are synthetic compounds with broad-spectrum fungistatic activity. Azoles can be divided into two groups the older imidazole agents, in which the hve-member azole nucleus contains two nitrogens, and the newer triazole compounds, fluconazole and itraconazole, in which the azole nucleus contains three nitrogens.

Another illustration of how the SFA can be used to understand polyelectrolyte adsorption layer properties will consider chitosan, a polyelectrolyte that is very appealing for practical use due to its natural origin and non-toxicity [128], acceptance in food [128, 129], biodegradability and biocompatibility, [130] antibacterial and fungistatic activity [129, 131]. 

In this study we report a Hansch analysis of the activity of a series of substituted trans-3-benzoylacrylic acids. The bacteriostatic and fungistatic activity of several series of substituted cis- and trans-3-benzoyl-acrylic acids and their methyl esters are given. The structure—activity relations observed are discussed.

Yeasts moderate activity. Typical MIC is 1200 pg/mL. The addition of propylene glycol may enhance the fungistatic activity of benzoic acid. 

Dimethyl sulfoxide has been shown to have bactericidal, bacteriostatic, and fungistatic activity, although the concentration required is dependent on the organism present. 

It is used as an alternative to benzalkonium chloride and other phenylmercuric preservatives and has both bacteriostatic and fungistatic activity. Increasing concerns over its safety have, however, led to questions regarding its continued use in formulations see Section 14. 

Crystal violet (Gentian violet), brilliant green and malachite green are triphenylmethane dyes widely used to stain bacteria for microscopic examination. They have bacteriostatic and fungistatic activity and have been applied topically for the treatment of infections. Due to concern about possible carcinogenicity, they are now rarely used.
