Concentrations, sulfur isotopic compositions and origin of organosulfur compounds in pore waters of a highly polluted raised peatland

Sulfur cycling in peatlands plays a key role in their response to atmospheric deposition of acid sulfate; however, the role of dissolved organic sulfur species has received little attention. In this study, we assess the quantitative importance of dissolved organic sulfur species in a heavily polluted peatland and their role in sulfur cycling. Surface and pore waters from a raised peat bog have been analyzed for dissolved organic and inorganic species. Except in the surface water, organically bound sulfur dominates over sulfate sulfur and the organosulfur is predominantly in the humic fraction, which is not GC amenable. Two organosulfur compounds are present in the GC amenable fraction at all depths; a compound containing a benzene ring, sulfone and amide groups dominates while a compound closely similar to either benzothiazole or 1,2-benzisothiazole is present at 100-1000 times lower concentrations. Other organosulfur species were detected in some samples by GC-AED (gas chromatography-atomic emission detection) at similar or yet lower concentrations but not identifiable with GC-MS. In the shallowest parts of the peat, sulfur isotopic data on the humic and non-humic dissolved organic sulfur fractions show a pronounced difference, implying different sources for these organosulfur compounds. Humic organosulfur is 34S enriched, indicating a source for this component from breakdown of plant materials, which have similar delta34S (0.1? and 4.2?). By contrast, the non-humic organosulfur is more 34S depleted at shallow depths (-11.7? in surface water), indicating an origin from reaction of bacterially produced sulfide (-9.9? in surface water) with dissolved organic material. Deeper in the peat the non-humic organosulfur becomes more 34S enriched (up to +6.8?), which may result from either: (i) reactions between organic material and more 34S enriched sulfide; or (less likely) (ii) a shift to production of non-humic organosulfur by breakdown of humic compounds or plant material in the peat matrix. These data highlight the importance of organosulfur species relative to inorganic species in peatland groundwaters. Organosulfur species comprise the bulk of the dissolved sulfur budget and are involved in the bacterial cycling of sulfur in the peatland ecosystem.

Synthesis and crystal structure of the 1-dimensional dihalide-bridged polymers : Dichlorobis(thiazole)iron(II) and dihromobis(thiazole)copper(II)

The new polymeric compound Fe(thiazole)2Cl2 (1) has been synthesised by the addition of thiazole to an ethanolic solution of anhydrous FeCl2. The structure of Cu(tz)2Br2 (2) has also been determined. The structures of both polymers consist of pseudo-octahedral units, doubly linked by halide-bridges to form infinite linear chains. Slight variation in the bonding of the two are observed, relating to the Jahn-Teller nature of Cu2+. Room temperature magnetic susceptibility measurements of 1 give an effective moment of 5.51(2) B.M., indicating high-spin Fe(II).

Biological studies on 1,2-benzisothiazole derivatives. VI. Antimicrobial activity of 1,2-benzisothiazole and 1,2-benzisothiazolin-3-one derivatives and of some corresponding 1,2-benzisoxazoles

Numerous 1,2-benzisothiazole and 1,2-benzisothiazolin-3-one derivatives, variously substituted in the different positions of the molecule, were tested for their in vitro antimicrobial activity. Some corresponding 1,2-benzisoxazoles and 1,2-benzisoxazolin-3-ones were also considered. Several compounds possess a potent and broad antibacterial and antifungal activity, particularly against Gram positive microorganisms, yeasts and dermatophytes. 1,2-Benzisothiazolin-3-ones were found to be the most active substances. On the contrary, the benzisoxazoles and the benzisoxazolin-3-ones considered were devoid of activity. The results obtained are discussed on the basis of structure-activity relationships.

Selective estrogen receptor degraders with novel structural motifs induce regression in a tamoxifen-resistant breast cancer xenograft

Potent estrogen receptor ligands typically contain a phenolic hydrogen-bond donor. The indazole of the selective estrogen receptor degrader (SERD) ARN-810 is believed to mimic this. Disclosed herein is the discovery of ARN-810 analogs which lack this hydrogen-bond donor. These SERDs induced tumor regression in a tamoxifen-resistant breast cancer xenograft, demonstrating that the indazole NH is not necessary for robust ER-modulation and anti-tumor activity.

Role of sulphur-heterocycles in medicinal chemistry: An update

From many decades, S-heterocycles have maintained their status as an important part and core of FDA approved drugs and medicinally active compounds. With exhaustive exploration of nitrogen heterocycles in medicinal chemistry, researchers have shifted their interest towards other heterocycles, especially, S-heterocycles. Thus several attempts have been made to synthesize a variety of new sulphur containing compounds with high medicinal value and low toxicity profile, in comparison to previous N-heterocycles. Till today, S-heterocycle containing compounds have been largely reported as anticancer, antidiabetic, antimicrobial, antihypertension, antivral, antinflammatory etc. In this review, the authors have tried to provide a critical analysis of synthesis and medicinal attributes of sulphur containing heterocycles such as thiirane, thiophene, thiazole, thiopyran, thiazolidine etc reported within last five years to emphasize the significance and usefulness of these S-heterocycles in the drug discovery process.

Palladium-catalysed reduction of heteroaromatic naphthyl ethers: Structural effects on reactivity

Tetrazolyl and benzisothiazolyl naphthylmethylic ethers 3 and 4(a-e) are stable crystalline compounds that can be synthesised in high yields by reaction of the corresponding naphthyl methanols (1a-e) with the derivatizing agents 2a and 2b. Experimental conditions for palladium-catalysed hydrogenolysis of ethers 3, 4, with a hydrogen donor and with molecular hydrogen, were investigated. Analysis of the structure and reactivity indicates that naphthylmethylic ethers 3 and 4 are structurally similar to the corresponding benzyloxyderivatives around the ether bond but exhibit different reactivity. Structural analysis for these compounds is based on crystallographic structure determinations, for 5-(2-naphthylmethoxy)-1-phenyltetrazole (3a) and 3-(2-naphthylmethoxy)-1,2- benzisothiazole 1,1-dioxide (4a), and molecular orbital DFT(B3LYP)/6-311G(d) calculations, for all ethers. It can be concluded from this investigation that 5-chloro-1-phenyltetrazole 2a acts as a better derivatizing agent for naphthyl methanols than 3-chloro-1,2-benzisothiazole-11-dioxide 2b, this contrasting with what has been observed with phenols, allylic and benzylic alcohols.
