苯甲酸丁酯用途Butyl benzoate as involatile solvent, for sampling of isocyanates with silica gel solid phase extraction. Butyl benzoate has been used as preservative in commercial cosmetic lotions. 3-(tert-Butyl)-4-hydroxyphenyl 2,4-dichlorobenzoate (1) was discovered 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. |
