Biological Activity

Nicotinic Acid is a water-soluble vitamin belonging to the vitamin B family. Nicotinic acid (Niacin) plays a key role in energy metabolism, cell signaling cascades regulating gene expression and apoptosis. Nicotinic acid (Niacin) is also used in the study of cardiovascular diseases.

Niacin (0-900 μM, 42 hours) significantly increases GSH levels and decreases ROS levels, and affects the expression of genes related to apoptosis and lipid metabolism. Niacin (0-40 μM, 24 hours) can inhibit cancer invasive activity at low dose but with no influence on proliferation.

Niacin (3-300 mg/kg; subcutaneous injection; once) can induce vasodilation in a dose-dependent manner within minutes in male C57BL/6 mice.

Conversion of different model animals based on BSA (PMID: 27057123)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
