Primary and secondary alcohols were efficiently sulfonylated in the presence of silver(I) oxide and potassium iodide in dichloromethane. The sulfonylation occurs under mild, neutral reaction conditions. The ease of isolation of the final product presents a marked advantage over the known methodologies.
The synthesis of glycero-lipids linked to colchicine derivatives is reported. The lipid structures are designed to perform two-dimensional crystallization experiments with tubulin, the structural subunit protein of microtubules.

Using click chemistry to enable both structural diversity and proteome profiling within a natural product derived library, two out of nineteen lipstatin analogues showed similar activity to Orlistat against fatty acid synthase (FAS), but with an improved ability to induce tumour cell death.

and n have meanings given in the description, which compounds have antiinflammatory activity (e.g. through inhibition of one or more of members of: the family of p38 mitogen-activated protein kinase enzymes; Syk kinase; and members of the Src family of tyrosine kinases) and have use in therapy, including in pharmaceutical combinations, especially in the treatment of inflammatory diseases, including inflammatory diseases of the lung, eye and intestines.
