DD04107

DD04107 is a neuronal exocytosis inhibitor with a rat Syt1-C2B domain binding K_a of 2.4 μM. DD04107 interferes with synaptobrevin-syntaxin-SNAP-25 complex formation and Syt1-SNARE complex interaction to block α-calcitonin gene-related peptide (α-CGRP) exocytotic release from primary sensory neurons. DD04107 blocks inflammatory ion channel recruitment to nociceptor plasma membranes. DD04107 can be used for the research of chronic inflammatory pain, neuropathic pain, osteosarcoma pain, chemotherapy-induced peripheral neuropathy, diabetic neuropathy, inflammatory pain.

For research use only. We do not sell to patients.

Biological Activity

Description

In Vitro

DD04107 (5-50 μM; 1 h pretreatment) dose-dependently inhibits capsaicin-induced α-CGRP release from neonatal Wistar rat dorsal root ganglion primary sensory neurons in culture, with significant inhibition observed at 5 μM and stronger inhibition at 50 μM^[1].
DD04107 (10 μM) does not exhibit significant binding affinity for most tested neuronal receptors, with only weak interactions (IC₅₀ > 10 μM) observed for a small subset of receptors^[1].
DD04107 (0.5-5 μM) does not inhibit hERG channel activity at 0.5 μM and 5 μM in human embryonic kidney 293 cells expressing hERG channels^[1].
DD04107 (10 μM; 1 h) inhibits capsaicin-induced α-CGRP exocytosis from primary sensory nociceptor neurons isolated from neonatal Wistar rat dorsal root ganglia by 47%^[2].
DD04107 binds selectively to the rat Syt1-C2B domain with a K_D of 2.4 μM, and does not interact with the rat Syt7-C2B domain^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
