生物活性

Letosteine is an orally active, potent and safe expectorant. Letosteine dissolves bronchial mucus and reduces respiratory inflammation symptoms, and restores gas exchanges and natural defense mechanisms in the lung. Letosteine can be used for acute or chronic respiratory diseases (such as bronchopneumopathies) research[1][2][3].

体内研究
(In Vivo)

Letosteine (Sprague-Dawley rats, 20 mg/kg, IV or Orally, once) is rapidly excreted with mainly in urine[4].

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

Animal Model: Sprague-Dawley rats
Dosage: 20 mg/kg
Administration: IV or Orally, once
Result: Rapidly was excreted with mainly in urine. More than 86% of the administered [14C]-radioactivity was recovered in urine within 72 h, 5-7% of the administered [14C]-radioactivity was recovered as 14CO2 in the expired air.

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.
