半岛bd体育手机客户端 描述

FEMA 4774 is a positive allosteric modulator of taste receptorsT1R2andT1R3, two subunits of the human sweet taste receptor. FEMA 4774 is also used as a sucrose sweetness enhancer[1].

FEMA 4774 (0-50 μM) induces a dose-dependent decrease in the EC50value of sucrose and significantly enhances the affinity of sucrose for its binding site with an α (effect of modulator on agonist affinity) value of 30 in the human sweet receptor cells[1].

FEMA 4774 (S9632) (oral gavage, 500-2000 mg/kg) does not cause a dose-dependent increase in polychromatic erythrocytes and induces micronuclei formation at dose levels up to 2000 mg/kg in Swiss albino (CD-1) mice[2].
