Emphysema

Emphysema is a long-term lung condition that causes shortness of breath. Over time, the condition damages the thin walls of the air sacs in the lungs called alveoli. Emphysema is a COPD-phenotype characterized by destruction of lung parenchyma. Alpha-1 antitrypsin deficiency (AATD) is a genetic cause of emphysema, whereas smoking is the most important risk factor of non-AATD emphysema. A general underappreciation of non-AATD emphysema has hampered progress in the field, and clinical guidelines have prohibited the use of emphysema as a diagnosis.

HY-P1645

Papain	9001-73-4
Papain is a cysteine protease of the peptidase C1 family. Papain enhances red cell agglutination by anti-D and anti-A, and increases red cell sensitivity to K cell-mediated lysis in ADCC assays. Papain can induce pulmonary emphysema. Papain can be used for the researches of Rh haemolytic disease of the newborn and pulmonary emphysema.

HY-P1645A

Papain (1.5-10 units/mg)	9001-73-4
Papain (1.5-10 units/mg) is a cysteine protease of the peptidase C1 family. Papain (1.5-10 units/mg) enhances red cell agglutination by anti-D and anti-A, and increases red cell sensitivity to K cell-mediated lysis in ADCC assays. Papain (1.5-10 units/mg) can induce pulmonary emphysema. Papain (1.5-10 units/mg) can be used for the researches of Rh haemolytic disease of the newborn and pulmonary emphysema.

HY-17428

Tripelennamine hydrochloride	154-69-8	99.81%
Tripelennamine hydrochloride is a histamine H1-receptor antagonist. Tripelennamine hydrochloride effectively reverses histamine-induced bronchoconstriction, increased transpulmonary pressure, elevated pulmonary vascular resistance and reduced dynamic compliance. Tripelennamine hydrochloride does not significantly affect arterial hypoxemia, hemoglobin desaturation and hypercapnia in horses undergoing short-term high-intensity exercise. Tripelennamine hydrochloride exhibits local and central analgesic activity. Tripelennamine hydrochloride can be used in studies related to emphysema, urticaria and acute laminitis.

HY-P1645B

Papain (lyophilized powder, ≥10 units/mg protein)	9001-73-4
Papain (lyophilized powder, ≥10 units/mg protein) is a cysteine protease of the peptidase C1 family. Papain (lyophilized powder, ≥10 units/mg protein) enhances red cell agglutination by anti-D and anti-A, and increases red cell sensitivity to K cell-mediated lysis in ADCC assays. Papain (lyophilized powder, ≥10 units/mg protein) can induce pulmonary emphysema. Papain (lyophilized powder, ≥10 units/mg protein) can be used for the researches of Rh haemolytic disease of the newborn and pulmonary emphysema.

Tripelennamine	91-81-6
Tripelennamine is a histamine H1-receptor antagonist. Tripelennamine effectively reverses histamine-induced bronchoconstriction, increased transpulmonary pressure, elevated pulmonary vascular resistance and reduced dynamic compliance. Tripelennamine does not significantly affect arterial hypoxemia, hemoglobin desaturation and hypercapnia in horses undergoing short-term high-intensity exercise. Tripelennamine exhibits local and central analgesic activity. Tripelennamine can be used in studies related to emphysema, urticaria and acute laminitis.

HY-153149

LJ-2698	945457-84-1
LJ-2698 is an orally active adenosine A3 receptor antagonist. LJ-2698 induces increased levels of anti-inflammatory cytokines in macrophages and significantly elevates the number of anti-inflammatory M2 macrophages in the lung. LJ-2698 prevents alveolar cavity enlargement, restores pulmonary function, inhibits matrix metalloproteinase activity and pulmonary cell apoptosis in the lung tissues of mice. LJ-2698 prevents renal injury, inhibits renal lipid accumulation, and increases PGC1α levels in renal tissues of mice with diabetic nephropathy. LJ-2698 is applicable to the research of emphysema and diabetic nephropathy.
