Sulindac Sulfide, but Not Sulindac Sulfone, Inhibits Colorectal Cancer Growth

Neoplasia: An International Journal for Oncology Research, 1999
Sulindac sulfide, a metabolite of the nonsteroidal antiinflammatory drug (NSAID) sulindac sulfoxide, is effective at reducing tumor burden in both familial adenomatous polyposis patients and in animals with colorectal cancer.

Microbial Degradation of the Sulfonate of Dodecyl Benzene Sulfonate [PDF]

Applied Microbiology, 1965
It has been observed that the sulfonate portion of alkyl benzene sulfonate (ABS) will undergo microbial attack in certain pure and mixed cultures if an energy source, such as glucose, is available. The evidence for this is provided by the stoichiometric relationship between the reduction of ABS concentration and the appearance of inorganic sulfur ...

Synthesis and Evaluation of Novel Benzofuran Derivatives as Selective SIRT2 Inhibitors

Molecules, 2017
A series of benzofuran derivatives were designed and synthesized, and their inhibitory activites were measured against the SIRT1–3. The enzymatic assay showed that all the compounds showed certain anti-SIRT2 activity and selective over SIRT1 and SIRT3 ...

[Sulfonylbis(bromomethylene)]dibenzene

IUCrData, 2022
The title compound, C14H12Br2O2S, crystallizes as the meso isomer of a diastereoisomeric pair. This structure determination was key to determining that the 1,3 elimination of bromine by triphenylphosphine occurs with inversion of the configuration at ...

Benzhydryl phenyl sulfone [PDF]

Acta Crystallographica Section E Structure Reports Online, 2009
In the title compound, C(19)H(16)O(2)S, the sulfur-bound phenyl group is approximately parallel to one of the two phenyl rings of the benzhydryl group, making a dihedral angle of 12.53 (10)°, and forms a dihedral angle of 41.25 (9)° with the other phenyl ring. In the crystal, weak C-H⋯O inter-actions form a two-dimensional network propagating along the
