Biological Activity

Propranolol HCl is a competitive, non-selective antagonist of beta-1 and beta-2 adrenergic receptors. By blocking beta-adrenergic receptor signaling, it suppresses intracellular cAMP accumulation and inhibits downstream protein kinase A (PKA) pathway activity. Consequently, this inhibition reduces vascular endothelial growth factor (VEGF) expression, leading to impaired cell proliferation, decreased migration, and attenuated angiogenesis in preclinical models.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
