- A convenient synthesis of a lymphocyte function-associated antigen-1 (LFA-1) antagonist of 'Compound 4'
-
The lymphocyte function-associated antigen-1 (LFA-1) antagonist of 'Compound 4' was synthesised by a convenient route using cheap, commercially available starting materials and catalysts under mild reaction conditions and by easily handled reactions. The total yield in the preparation of 'Compound 4' was more than 38% via Sonogashira coupling of an iodide and an alkyne, reduction of the alkyne catalysed by Raney nickel and later steps involving hydrolysis of an ester, condensation of an acid and an amine and a final hydrolysis of an ester.

- Preparation of fluorous Yamaguchi reagents and evaluation of their reactivity in esterification
-
Fluorous Yamaguchi (FY) reagents bearing a perfluoroalkyl chain were prepared and employed in esterification reactions; the yields were similar to those obtained with the traditional Yamaguchi (TY) reagent. Fluorous benzoic acids derived from the FY reagents were separated easily after the reaction. GC analysis revealed that the initial rates of reaction with the FY reagents were higher than those with the TY reagent. The acidities of benzoic acids produced from the FY and TY reagents were predicted by DFT to be similar (1.20 and 0.96, respectively).

- Discovery and SAR study of 3-(tert-butyl)-4-hydroxyphenyl benzoate and benzamide derivatives as novel farnesoid X receptor (FXR) antagonists
-
3-(tert-Butyl)-4-hydroxyphenyl 2,4-dichlorobenzoate (1) was discovered in our in-house high throughput screening as a moderate FXR antagonist. To improve the potency and the stability of the hit 1, forty derivatives were synthesized and SAR was systematically explored. The results turn out that replacing the 2,4-dichlorophenyl with 2,6-dichloro-4-amidophenyl shows great improvement in potency, replacing the benzoate with benzamide shows improvement in stability and slight declining of potency and 3-(tert-butyl)-4-hydroxyphenyl unit is essential in obtaining the FXR antagonistic activity.
