Biochem/physiol Actions

BIBN4096BS (Olcegepant) is a potent calcitonin gene-related peptide (CGRP) receptor antagonist with higher affinity/potency toward human over rat & mouse receptor (human/rat Ki = 14.4 pM/3.4 nM by binding assay; human/mouse Kb = 8 pM//7.711 nM by cellular cAMP assay). BIBN4096BS inhibits facial blood flow by electrical stimulation of marmoset monkey trigeminal ganglion (IC50 = 3 μg/kg i.v.) without any intrinsic cardiovascular effects. Studies using anaesthetized rats reveals that BIBN4096BS antagonism against trigeminal nociceptive stimulation by capsaicin is limited to the spinal trigeminal nucleus, but not trigeminal ganglion. Also widely employed for in vivo studies in mice.

Transgenic knock-in (KI) mice that express CaV2.1 channels containing an R192Q gain-of-function mutation in the α1A subunit known to cause familial hemiplegic migraine type-1 in patients, exhibit key disease characteristics and provide a useful tool to investigate pathophysiological mechanisms of

Glucagon-like peptide (GLP)-1 is an incretin hormone and its mimetics are proven antidiabetic and antiobesity drugs. GLP-1 exerts antimotility and mucosal proliferative activities but its epithelial ion transport effects are uncharacterized and these may contribute to the gastrointestinal (GI) disturbance

Several lines of evidence suggest that a calcitonin-gene related peptide (CGRP) receptor antagonist may serve as a novel abortive migraine treatment. Here we present data on a human cell line and isolated human vessels for such an antagonist, BIBN4096BS. On

Cortical spreading depression (CSD) is believed to promote migraine headache by enhancing the activity and mechanosensitivity of trigeminal intracranial meningeal afferents. One putative mechanism underlying this afferent response involves an acute excitation of meningeal afferents by cortical efflux of K+

Olcegepant (BIBN4096BS) is a selective non-peptide CGRP receptor antagonist with acute antimigraine properties. Since systemic vascular tone is modulated by perivascular (primary sensory CGRPergic and sympathetic) nerves, this randomized study investigated in pithed rats the effect of acute i.v. treatment
