Pronounced activity of aromatic selenocyanates against multidrug resistant ESKAPE bacteria

“…Notably, the direct analogues of allyl(iso-)thiocyanates are rather unpleasant substances. The aromatic counterparts (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13), shown here with their synthesis and respective percentage yields, are more promising candidates in the context of modern drug development.…”

“…Table 1. Antimicrobial activity of arylmethyl selenocyanates against selected bacteria from non-ESKAPE and ESKAPE families of bacteria and yeasts (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13). Although practical applications are more speculative at this time, these results indicate that the aromatic selenocyanates may also serve as excellent nematicidal agents, possibly against pathogenic nematodes affecting plants, animals and humans -clearly a matter of further investigation.…”

“…[5][6][7] These phytochemicals include alkaloids, flavonoids, terpenes, polyphenols and, particularly, organosulfur compounds (OSCs). [8][9][10][11] OSCs are distributed widely in Nature, for instance as allicin in garlic, ergothioneine in mushrooms, and thiocyanates and isothiocyanates in cruciferous vegetables, to name just a few (Figure 1). [12][13][14] Isothiocyanates and thiocyanates are reactive, electrophilic substances belonging to the class of natural Reactive Sulfur Species (RSS) and are cherished for their ability to randomly modify cysteine proteins and enzymes of the cellular thiolstat.…”

Colorimetric assay and deodorizing/antibacterial performance of natural fabrics dyed with immature pine cone extract

“…The antibacterial activity of immature pine cone extract was supposed to be attributed to lignin and tannin components in immature pine cone extract and terepenes. 17-20,23-28 Immature pine cone extract is composed of components (hemicellulose, lignin, cellulose and tannin) and many unknown components. Therefore, it is very difficult to find the exact components which were effective antibacterial activity to microorganisms.…”

“…The antibacterial properties of their components are exploited in such diverse commercial products as dental root canal sealers, antiseptics, food preservatives and feed supplements. [23][24][25][26][27][28] The pinenes, the main volatile components of the pine cone, have been used as an anti-cancer agent, also for anti-inflammatory, antiseptic, expectorant and bronchodilatorin traditional Chinese medicine, and as artificial odorants in the chemical industry. 29 In our previous studies, dyeing property, fastness, deodorizing/antibacterial properties of cotton, silk, and wool fabrics dyed with some natural colorants (sappan wood, black tea, peony, clove, gardenia, coffee sludge, Cassia tora.…”
