Asocainol hydrochloride ia an antiarrhythmic drug which inhibits slow Ca2+ influx. This is accompanied by alterations in normal Na+-carried action potentials. Therefore, Asocainol not only inhibits Ca2+ inflow but also interferes with the fast inward Na+ current.
PD-85639 is a voltage-gated sodium (Na+) channel blocker (75% in 10 min & >95% in 25 min blockage of Na+ current by 25 μM PD85,639; whole-cell patch clamp using primary rat brain neurons) that is shown to target rat brain Nav1.2 with simultaneous high- and low-affinity modes of binding (EC50 = 56 nM 40% & 20 μM 60% at pH 9.0, 5 nM 28% & 3 μM 72% at pH 7.4, against 2 nM [3H]-PD85,639 for binding rat brain synaptosomes; EC50 = 17 nM 39% & 10 μM 61% using at pH 9.0 using rat brain synaptosome membranes) and a fast kinetic (t1 2 = 1.2 at 4°C, <0.5 min at 25°C), competitive against the local anesthetic Na+ channel blockers tetracaine, bupivacaine, and mepivacaine, as well as Na+ channel activators veratridine and batrachotoxin (K1 = 0.26 μM against 5 nM [3H]-BTX for binding rat neocrotical membranes).
The binding affinities of ganoderic acid DM andGanoderic acid ζ (ÎGbind, -16.83 and-10.99 kcal mol-1) are comparable to that of current commercial drug oseltamivir (-23.62 kcal mol-1);Ganoderic acid DM is a potential source of anti-influenza ingredient, with novel binding pattern and advantage over oseltamivir, it has steric hindrance on the 150 cavity of N1 protein, and exerts activities across the H274Y and N294S mutations, is the attractive candidates of novel neuraminidase (NA) inhibitors.Ganoderic acid zeta has cytotoxicity in vitro against Meth-A and LLC cell lines.
Egg-laying hormone (ELH) is a neuropeptide synthesized by the bag cell neurons, Egg-laying hormone (ELH) induces egg laying and its correlated behavior in Aplysia californica. Egg-laying hormone (ELH) has been purified to homogeneity and Egg-laying hormon
Potent rat Nav1.7, human Nav1.4 and rat Nav1.6 channel activator (EC50 values are 7, 10 and 47 nM, respectively). Exhibits minimal activation at mammalian Nav1.2, Nav1.3 and Nav1.5 (EC50 values >3 μM). Inhibits fast inactivation on all channels. Increases
