Bioactive Aliphatic Sulfates from Marine Invertebrates

open access: yesMarine Drugs, 2019
The occurrence of sulfated steroids and phenolics in marine organisms is quite widespread, being typically reported from Echinoderms. In contrast, alkane and alkene aliphatic sulfates are considerably rarer with examples being reported from a diverse ...

Bacterial carbonic anhydrases as drug targets: towards novel antibiotics ?

open access: yesFrontiers in Pharmacology, 2011
Carbonic anhydrases (CAs, EC 4.2.1.1) are metalloenzymes which catalyze the hydration of carbon dioxide to bicarbonate and protons. Many pathogenic bacteria encode such enzymes belonging to the a-, b-, and/or g-CA families.

Mechanistic Study of an Improved Ni Precatalyst for Suzuki–Miyaura Reactions of Aryl Sulfamates: Understanding the Role of Ni(I) Species

open access: yesJournal of the American Chemical Society, 2017
Nickel precatalysts are potentially a more sustainable alternative to traditional palladium precatalysts for the Suzuki–Miyaura coupling reaction. Currently, there is significant interest in Suzuki–Miyaura coupling reactions involving readily accessible ...

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

open access: yesAngewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

Synthesis, biological evaluation, and stability studies of raloxifene mono- and bis-sulfamates as dual-targeting agents.

open access: yesBioorganic & Medicinal Chemistry
All three possible sulfamate derivatives of the selective estrogen receptor modulator Raloxifene (bis-sulfamate 7 and two mono-sulfamates 8-9) were synthesized and evaluated as inhibitors of the clinical drug target steroid sulfatase (STS), both in cell ...

Highly fluorinated sulfamates with thermotropic liquid crystalline properties

open access: yes, 2015
International audienceTwo original series of highly fluorinated sulfamates and biphenyls having thermotropic mesophases are synthesized and their liquid crystal properties are studied by differential scanning calorimetry (DSC) and polarizing optical ...

Iron-Catalyzed Alkylations of Aryl Sulfamates and Carbamates

open access: yes, 2016
The alkylation of aryl sulfamates and carbamates using iron catalysis is reported. The method constructs sp2–sp3 carbon–carbon bonds and provides synthetically useful yields across a range of substrates (>35 examples).

Efficacious N-protection of O-aryl sulfamates with 2,4-dimethoxybenzyl groups

open access: yes
Sulfamates are important functional groups in certain areas of current medicinal chemistry and drug development. Alcohols and phenols are generally converted into the corresponding primary sulfamates (ROSO2NH2 and ArOSO2NH2, respectively) by reaction ...

Review of aluminum solubility behavior in the Hanford 200 South West Area tanks targeted for retrieval

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract The behavior of aluminum‐bearing phases in tank wastes from the southwest quadrant of the Hanford Site's 200 West Area primarily determines solids accumulation, retrieval performance, and downstream processability. This review synthesizes historical tank characterization data, laboratory dissolution studies, and process‐relevant observations ...
