Molarity Calculator

Frakefamide is a potent analgesic that acts as a peripheral active μ-selective receptor agonist. Frakefamide is unable to penetrate the blood-brain-barrier and enter the central nervous system.

At equivalent molar concentrations, both the salt and free forms of a compound exhibit comparable biological activity. Nevertheless, the salt form (Frakefamide TFA) usually boasts enhanced water solubility and stability.

Description	Frakefamide is a potent analgesic that acts as a peripheral active μ-selective receptor agonist. Frakefamide is unable to penetrate the blood-brain-barrier and enter the central nervous system^[1]^[2].
In Vivo	Frakefamide (LEF576) yields a dose dependent increase in morphine appropriate responding to 50% at the highest dose tested (10 μmol/kg) after infusion durations of 2 min, whereas after 15 min infusions a maximum of 25% morphine appropriate responding was occasioned at 17.5 μmol/kg^[1]^[2]. MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.
