Brevetoxin-3 (PbTx-3) is a potent allosteric voltage-gated Na⁺ channel activator and has multiple active centers (A-ring lactone, C-42 of R side chain). Brevetoxin-3 (PbTx-3) has a high affinity to site 5 of the voltage-sensitive Na⁺ channels, inhibits the inactivation of Na⁺ channels and prolongs the mean open time of these channels. Brevetoxin-3 (PbTx-3) repeated exposures can lead to prolonged airway hyperresponsiveness (AHR) and lung inflammation.

N-Methylhistamine dihydrochloride (Nα-Methylhistamine dihydrochloride) is a non-selective Histamine receptor agonist. N-Methylhistamine dihydrochloride activates histamine H₁, H₂ and H₃ receptors; it stimulates central H₁ receptors by activating sympathetic α and β adrenergic receptors to inhibit intestinal transit, exerts dose-dependent inhibition on intestinal transit, reduces histamine turnover in mouse brains, and increases gastric acid secretion without altering plasma gastrin concentrations. N-Methylhistamine dihydrochloride produces a pH-dependent, voltage-independent potentiating effect on acid-sensing ion channel 1a, and shows no significant activity toward homologous ASIC2a channels. N-Methylhistamine dihydrochloride can be used in studies related to Helicobacter pylori infection.

Lu AE98134, an activator of voltage-gated sodium channels, acts as a partly selective Na_v1.1 channels positive modulator. Lu AE98134 also increases the activity of Na_v1.2 and Na_v1.5 channels but not of Na_v1.4, Na_v1.6 and Na_v1.7 channels. Lu AE98134 can be used to analyze pathophysiological functions of the Na_v1.1 channel in various central nervous system diseases, including cognitive restoring in schizophrenia, et al.

ErSO-TFPy (TEQ103) is an ERα+ tumor cell inhibitor with low nanomolar cytotoxic activity against ERα+ breast cancer cells.
