A novel small molecule, AS1, reverses the negative hedonic valence of noxious stimuli.

Pain is the primary reason people seek medical care, with chronic pain affecting ~ 20% of people in the USA. However, many existing analgesics are ineffective in treating chronic pain, while others […]

Structure-Activity Relationships and Therapeutic Potential of Purinergic P2X7 Receptor Antagonists.

The purinergic P2X7 receptor (P2X7R), an ATP-gated non-selective cation channel, has emerged as a gatekeeper of inflammation that controls the release of pro-inflammatory cytokines. As a key player in initiating […]

Conserved but not critical: Trafficking and function of Na1.7 are independent of highly conserved polybasic motifs.

Non-addictive treatment of chronic pain represents a major unmet clinical need. Peripheral voltage-gated sodium (Na) channels are an attractive target for pain therapy because they initiate and propagate action potentials […]

Altered cerebral neurovascular coupling in medication-overuse headache: A study combining multi-modal resting-state fMRI with 3D PCASL.

Structural and functional changes in the brain have been identified in individuals with medication-overuse headache (MOH) using MRI. However, it has not been clearly established whether neurovascular dysfunction occurs in […]

Diclofenac and other non-steroidal anti-inflammatory drugs (NSAIDs) are competitive antagonists of the human P2X3 receptor.

The P2X3 receptor (P2X3R), an ATP-gated non-selective cation channel of the P2X receptor family, is expressed in sensory neurons and involved in nociception. P2X3R inhibition was shown to reduce chronic […]

Calcitonin gene relating peptide inhibitors in combination for migraine treatment: A mini-review.

The discovery of calcitonin gene-related peptide (CGRP) and its role in migraine pathophysiology has led to advances in the treatment of migraine. Since 2018, the Food and Drug Administration (FDA) […]

5-Alkoxy-1-aryl-3-polyfluoroalkylpyrazoles with Antinociceptive Activity: Partial Agonists of TRPV1 Ion Channels.

Chemoselective O-alkylation of 1-aryl-3-polyfluoroalkylpyrazol-5-oles under basic conditions resulted in a series of 5-alkoxypyrazoles (26 derivatives). They were showed to have an acceptable ADME profile (in silico). In experiments in vivo […]
