Dantrolene sodium - CAS 14663-23-1
Catalog number: B0046-059070
Category: APIs
Molecular Formula:
Molecular Weight:
Dantrolene sodium is a postsynaptic muscle relaxant that lessens excitation-contraction coupling in muscle cells. It suppresses the release of calcium previously sequestered by skeletal, but not cardiac, muscle sarcoplasmic reticulum.

OXA potentiates glucose-stimulated [Ca2+]i increase via the activation of ryanodine receptors To investigate the downstream signalling mechanism following the OXA-induced cAMP increase, glucose-stimulated [Ca2+]i changes were measured in the presence of various cAMP signaling pathway inhibitors in the primary beta cells. OXA further increased the [Ca2+]i levels in response to high glucose (Fig. 2a).AsshowninFig. 2b, the stimulatory effect of OXA on [Ca2+]i was not observed in the presence of the PLC inhibitor, PKC inhibitor or AC inhibitor or in the presence of H-89 (a non-selective inhibitor of protein kinase A [PKA]) or brefeldin-A (BFA; a non-selective inhibitor of exchange protein activated by cAMP [EPAC]). However, the involvement of EPAC signalling, compared with that of PKA, was more predominant for the stimulatory effect of OXA on the glucose-stimulated [Ca2+]i increase. Because the activation of the Ins(1,4,5)P3 receptor (IP3R) in response to cAMP signalling is a PKA-dependent mechanism and the activation of ryanodine receptors (RyRs) is an EPAC-dependentmechanism, we next investigated the effect of OXA on glucose-stimulated [Ca2+]i increase in the presence of the IP3R antagonist xestospongin C and the RyR antagonist dantrolene sodium. The stimulatory effect of OXA on [Ca2+]i was remarkably reduced not only in the presence of the RyR antagonist but also in the presence of the IP3R antagonist (Fig. 2c, d). However, the involvement of RyR signaling was more predominant than the involvement of IP3Rsignalling for the stimulatory effect of OXA on the [Ca2+]i increase.
