Baicalin, a natural LSD1 inhibitor.

Area of Science:

• Biochemistry
• Pharmacology
• Medicinal Chemistry

Background:

• Baicalin is a key active compound found in skullcap.
• It exhibits diverse pharmacological activities including antihypertensive, sedative, hepatoprotective, choleretic, antibacterial, and anti-inflammatory effects.

Purpose of the Study:

• To investigate the potential of baicalin as a Lysine-Specific Demethylase 1 (LSD1) inhibitor.
• To characterize the inhibitory activity of baicalin against LSD1.

Main Methods:

• Biochemical assays were performed to determine the inhibitory concentration 50 (IC50) of baicalin against LSD1.
• Cell-based assays were utilized to confirm the LSD1 inhibitory effect of baicalin.

Main Results:

• Baicalin was characterized as an LSD1 inhibitor with an IC50 value of 3.01μM.
• Baicalin demonstrated a potent inhibitory effect on LSD1 activity within cellular models.

Conclusions:

• Baicalin possesses significant LSD1 inhibitory properties.
• Baicalin can serve as a foundational structure for the development of novel flavone-based LSD1 inhibitors.
