生物活性

FEMA 4774 is a positive allosteric modulator of taste receptors T1R2 and T1R3, two subunits of the human sweet taste receptor. FEMA 4774 is also used as a sucrose sweetness enhancer[1].

体外研究
(In Vitro)

FEMA 4774 (0-50 μM) induces a dose-dependent decrease in the EC50 value 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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
