CAS#: 196612-93-8

Description: Falnidamol, also known as BIBX 1382, is a pyrimido-pyrimidine with antitumor activity. BIBX 1382 inhibits the intracellular tyrosine kinase domain of the Epidermal Growth Factor Receptor (EGFR) thus specifically reversing the aberrant enzymatic activity from overexpressed and constitutively activated EGFR, and subsequently inhibiting cell proliferation and inducing cell differentiation. Check for active clinical trials or closed clinical trials using this agent.

Preparing Stock Solutions

The following data is based on the product molecular weight 387.84 Batch specific molecular weights may vary from batch to batch due to the degree of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 1.15 mL 5.76 mL 11.51 mL
5 mM 0.23 mL 1.15 mL 2.3 mL
10 mM 0.12 mL 0.58 mL 1.15 mL
50 mM 0.02 mL 0.12 mL 0.23 mL
