Veldoreotide TFA
Based on 1 Customer Validation
Veldoreotide (DG3173) TFA a somatostatin analogue, binds to and activate the somatostatin receptors (SSTR) 2, 4, and 5. Veldoreotide TFA inhibits growth hormone (GH) secretion in adenomas compared with Octreotide (HY-P0036). Veldoreotide has the potential to be used as pain modulating agent

SSTR2 37.6 nM (EC50) |
SSTR3 31.3 nM (EC50) |
SSTR4 10.5 nM (EC50) |
Veldoreotide stimulates the SST2, SST4, and SST5 receptors with high potency and efficacy in the HEK293 cells, co-expressing these receptors with the GIRK2 channels; EC50s of 37.6 ± 4.5 nM, 31.3 ± 14.4 nM and 10.5 ± 3.4 nM for GIRK2-SST2, GIRK2-SST4 and GIRK2-SST5, respectively[1].
Veldoreotide (10 μM; 24 h) inhibits SST4-expressing BON-1 cells[1].
Veldoreotide (DG3173) (100 nM or 1 μM; 6 h) inhibits GH secreation in adenomas with an IC50 of 0.49 nM[2].
