Poly(phenolic)-sulfonates demonstrated very good cytotoxicity against the growth of tumor cell lines (L1210, Tmolt-(3), HeLa-S(3)) and are comparable in potency with typical clinically used anticancer drugs. Four of the most active compounds, i.e. GL-2021, GL-2029, GL-2041 and GL-2063, were selected for a mode of action study in L1210 lymphoid leukemia cells at concentration of 25muM to 100muM ...

Thiols (RSH) or thiolates (RS) are one of the most popular anchor groups used for attaching molecules to gold electrodes in molecular junction devices. Operation of these devices under oxidizing conditions may lead to oxidation of the thiolate anchor groups. Herein we investigate the plausibility of this process as a potential source of current fluctuation. Density functional theory calculation...

Plant growth is highly dependent on bacteria, saprophytic, and mycorrhizal fungi which facilitate the cycling and mobilization of nutrients. Over 95% of the sulfur (S) in soil is present in an organic form. Sulfate-esters and sulfonates, the major forms of organo-S in soils, arise through deposition of biological material and are transformed through subsequent humification. Fungi and bacteria r...

Organically bound sulfur makes up about 90% of the total sulfur in soils, with sulfonates often the dominant fraction. Actinobacteria affiliated to the genus Rhodococcus were able to desulfonate arylsulfonates in wheat rhizospheres from the Broadbalk long-term field wheat experiment, which includes plots treated with inorganic fertilizer with and without sulfate, with farmyard manure, and unfer...

The most common anionic surfactants in the formulation of detergents are Linear Alkylbenzene Sulfonates (LAS), with an sulfonate head group and a hydrophobic alkylbenzene tail group. two primary synthetic detergents, together sodium laureth sulphate, have been around for quite some time may be found many personal-care items such as shampoos, soaps, toothpaste, laundry detergent. LAS is relative...
