1. Peimisine (Ebeiensine) can affect M-receptor, excit β-receptor, restrain the release of internal calcium, and promote to releaseing nitrogen monoxidum in order to relax tracheal smooth muscle and relieve asthma. 2. Peimisine can attenuate lung tissue injury( ALI), LDH and MDA amount in ALI mice in a dose dependent manner, it also lower the total protein, total white blood cells, lymphocyte and neutrophilic leukocyte in bronchoalveolar lavage fluid( BALF); suggests that peimisine can play a protective role against LPS-induced acute lung injury. 3. Peimisine has the protective effect on the experimental hepatic fibrosis formation, the possible mechanisms are associated with inhibiting fibrogenesis and fibrosis accumulation, and decreasing lipid peroxidation. 4. Peimisine can inhibit angiotensin I converting enzyme activity in a dose-dependent manner, displaying 5 % inhibitory concentration values of 526.5 microM, thus, it may have antihypertensive action.

1. Shionone (Shionon) has anti-tussive and anti-inflammatory effects.

Aurintricarboxylic acid (NSC-4056) is a strong inhibitor of topoisomerases and other nucleases. It is a potent inhibitor of ribonuclease and topoisomerase II by preventing the binding of the nucleic acid to the enzyme.

Oxomemazine is a phenothiazine-based histamine H1-receptor blocker with pronounced antimuscarinic activity. It is a selective antagonist of mycotoxins M1 receptors, exhibiting high (Ki=84 nM, M1 receptors) and low (Ki=1.65 μM, M2 receptors) affinity, with a 20-fold difference. Oxomemazine is an antihistamine and anticholinergic agent used in cough studies[1][2].

Eliapixant (BAY 1817080) (BAY 1817080) is a potent and selective P2X3 receptor antagonist, with an IC50 of 8 nM. Eliapixant can be used for the research of refractory chronic cough.

Gefapixant (AF219) is a P2X3 receptor (P2X3R) antagonist with IC50 of ~30 nM at recombinant hP2X3 homotrimers and 100-250 nM at hP2X2/3 heterotrimeric receptors.

DF-1012 FA is a structural analog of DF-1012, a neuropeptide inhibitor used in the study of asthma and cough.

SCH-486757 is an agonist of nociceptin-1 (NOP1) and orphanin FQ peptide receptors and is used in the study of cough.

GW 833972A is a selective CB2 receptor agonist that inhibits induced neural depolarization and citric acid-induced cough in an animal model.

Oxeladin citrate is a highly potent and effective cough suppressant, which can treat all types of cough of various etiologies. It is not related to opium or its derivatives, so treatment with oxeladin is no risk of addiction. And it has none of the side effects (such as hypnosis, respiratory depression, tolerance, constipation and analgesia) which are present when common antitussives. It can used at every age, as well as in patients with heart disease, since it is high level of safety and a great selectivity to act on the bulbar centre of cough.

Sulfogaiacol (guaiacolsulfonate) is an antitussive agent, used for acute respiratory tract infections and cough.

Dropropizine (UCB-1967), a racemic non-opiate antitussive agent, is served as a cough suppressant.

Carbetapentane citrate (Pentoxyverine citrate) , an antitussive (cough suppressant), is frequently used for a cough related to illnesses like the common cold.

Erdosteine (RV 144) is a homocysteine-derived thiol derivative with mucolytic and free radical scavenging properties. Erdosteine and its metabolites modulate mucus production and viscosity, by which facilitating mucociliary transport and improving expectoration. This agent also suppresses the chemical-induced cough reflex as well as protects lung tissues from damages caused by cigarette smoking mediated through free radicals scavenging.

Gefapixant citrate (AF-219 citrate) is an orally available, highly potent P2X3 receptor antagonist with antitussive properties that inhibits hP2X2/3. It can be used to study chronic cough.

(+)-Dropropizine can inhibit histamine receptor, anti-allergic, and reduce a cough by modulation of neuropeptides involved in the cough reflex and by interfering with stimulus activation of peripheral endings of sensory nerves.

Diethylaminoethoxyethanol is served in the production of cough medicine Toclase and so on.

Oxolamine hydrochloride is a cough suppressant which may be useful in the treatment of pediatric asthma.

Pimethixene maleate (Pimetixene maleate) is a potent 5-HT2B receptor antagonist with sedative and antitussive activity.Pimethixene maleate inhibits 5-HT1A, 5-HT2A, 5-HT2B, 5-HT2C, histamine H1, dopamine D2 and D4.4 as well as muscarinic M1 and M2, and can be used in studies of dry and irritant cough in children. irritant cough in children.
