Biological Activity

para-Nitroblebbistatin is a non-cytotoxic, photostable, fluorescent and specific Myosin II inhibitor, usd in the study of the specific role of myosin II in physiological, developmental, and cell biological studies.

Chemical Information
Molecular Weight 337.33
Formula C18H15N3O4
CAS Number 1621326-32-6
Form Solid
Solubility (25°C) DMSO 22 mg/mL (ultrasonic and warming and heat to 60°C)
Storage Powder -20°C
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.
