PF 00356231 is a selectivity inhibitor MMP-12 and can be used in studies about the treatment of emphysema and chronic obstructive pulmonary disease (COPD).

SSR69071 is a potent, orally active, and selective inhibitor of neutrophil elastase. SSR69071 displays a higher affinity for human elastase (Ki =0.0168 nM) than for rat (Ki =3 nM), mouse (Ki =1.8 nM), and rabbit (Ki = 58 nM) elastases [2]. SSR69071 reduces myocardial infarct size following ischemia-reperfusion injury [1]. SSR69071 also has the potential for the treatment of chronic obstructive pulmonary diseases, asthma, emphysema, cystic fibrosis, and several inflammatory diseases.

Lysozyme chloride, a bactericidal enzyme, specifically targets and lyses gram-positive bacteria. Additionally, it is utilized in the research of HIV infection and pulmonary emphysema [1] [2] [3].

Isoetharine mesylate salt (Isoetarine mesilate) is a β-adrenergic receptor agonist. it also is pregnane X receptor (PXR) activator capable of upregulating CYP450 expression.

Diphylline (Diprophylline) is a xanthine derivative. Diphylline exerts bronchodilator effects and to a lesser extent vasodilator and diuretic properties. Diphylline probably acts as a competitive inhibitor of phosphodiesterase which leads to an increase in intracellular cAMP. This results in relaxation of bronchial smooth muscle and other smooth muscles. Diphylline may also antagonize adenosinereceptors. Diphylline is used in the treatment of acute bronchial asthma, chronic bronchitis and emphysema.

Spirofylline is an agent of bronchodilator, has the potential for asthma and bronchitis and emphysema treatment.

Hexoprenaline Sulfate is a selective beta2-adrenoreceptor agonist. Hexoprenaline Sulfate is active in man as a bronchodilator by the oral or intravenous routes and by inhalation. Hexoprenaline Sulfate is indicated for use in the treatment of bronchospasm

Isoetharine is a selective agonist of β2-adrenergic receptor used as a bronchodilator for emphysema, bronchitis, and asthma.

Porcine pancreatic elastase is a serine protease composed of a single polypeptide chain with 240 amino acid residues. It has the ability to hydrolyze polypeptides and proteins, and can induce emphysema in hamsters.

Acefylline piperazine is a stimulant drug of the xanthine chemical class. It acts as an adenosine receptor antagonist. Acephylline piperazine is a theophylline derivative with a direct bronchodilator action. It has the advantages over theophylline in being far less toxic and producing minimal gastric irritation. It is indicated for the treatment of asthma, emphysema, acute and chronic bronchitis associated with bronchospasm.Acefylline relaxes smooth muscles, relieves bronchospasm & has a stimulant effect on respiration. It stimulates the myocardium & central nervous system, decreases peripheral resistance & venous pressure & causes diuresis. The mechanism of action is still not clear, inhibition of phosphodiesterase with a resulting increase in intracellular cyclic AMP does occur, but not apparently at concentrations normally used for clinical effect. Other proposed mechanisms of action include adenosine receptor antagonism, prostaglandin antagonism & effects on intracellular......

Neltenexine is an elastase inhibitor that may be useful for preventing pulmonary emphysema.

Ipratropium-d3 Bromide is a deuterated compound of Ipratropium Bromide. Ipratropium Bromide has a CAS number of 22254-24-6. Ipratropium is a synthetic anticholinergic agent that is used as an inhalant for treatment of acute bronchospasm due to chronic bronchitis and emphysema.

Diprophylline-d6 is a deuterated compound of Diprophylline. Diprophylline has a CAS number of 479-18-5. Dyphylline is a xanthine derivative. Dyphilline exerts bronchodilator effects and to a lesser extent vasodilator and diuretic properties. Dyphilline probably acts as a competitive inhibitor of phosphodiesterase which leads to an increase in intracellular cAMP.

Neltenexine HCl is the salt form of Neltenexine free base, an elastase inhibitor that may be useful for preventing pulmonary emphysema.

Aclidinium bromide (LAS-W 330) is a synthetic anticholinergic agent that is used as an inhalant for treatment of acute bronchospasm due to chronic bronchitis or emphysema. Aclidinium has not been implicated in causing liver enzyme elevations or clinically apparent acute liver injury.

Ipratropium Bromide (Sch 1000) is a synthetic anticholinergic agent that is used as an inhalant for treatment of acute bronchospasm due to chronic bronchitis and emphysema.

IA-Alkyne (Iodoacetamide-alkyne) is a TRP channel (TRPC) agonist. IA-Alkyne can be used to develop an isotopically tagged probe for quantitative cysteine-reactivity profiling. It also has the potential for the study of respiratory infection.
