Synonyms: ABT-773; Abbott-195773; A-195773
Cethromycin (ABT-773; Abbott-195773) is an orally effective ketolide antibiotic with broad-spectrum antibacterial activity. Cethromycin binds to domains II/V of the 23S rRNA of the 50S subunit, inhibiting bacterial protein synthesis. Cethromycin can accumulate in lung tissue, alveolar macrophages, epithelial lining fluid, and human polymorphonuclear leukocytes. Cethromycin exhibits potent in vitro activity against a variety of respiratory pathogens, including Mycoplasma pneumoniae. Cethromycin exhibits significant intracellular and pulmonary enrichment and anti-inflammatory effects against mycoplasma pneumonia in mouse models, improving airway obstruction and airway hyperresponsiveness. Cethromycin disrupts the apicoplast and reduces liver-stage parasite burden during the liver stage of Plasmodium berghei. Cethromycin can be used in research related to pneumonia, Staphylococcus aureus infection, gonorrhea, and malaria .

Cat. No.: HY-N3945
CAS No.: 475-81-0
Synonyms: O,O-Dimethylisoboldine; S-(+)-Glaucine; NSC 34396
Glaucine (O,O-Dimethylisoboldine) is an alkaloid extracted from Glaucium flavum that possesses various activities, including cough relief, bronchodilation, anti-inflammatory effects, analgesia, antipyretic properties, and anticancer effects. Glaucine acts as a selective and orally active inhibitor of phosphodiesterase 4 (PDE4), with a Ki of 3.4 µM in human bronchial tissues and polymorphonuclear leukocytes. Glaucine induces relaxation of human isolated bronchi by antagonizing calcium channels. Additionally, Glaucine inhibits the activation of NF-κB, leading to a reduction in the expression of the MMP-9 gene, thereby suppressing the migration and invasion of breast cancer cells. Therefore, Glaucine holds potential for research in asthma and breast cancer .

GEA 3162 is an orally active compound that acts as a NO/ONOO⁻ donor. GEA 3162 significantly inhibits the activation of human polymorphonuclear leukocytes (PMNs) through the cGMP pathway, inhibits the release of inflammatory mediators, and exerts anti-inflammatory and protective effects. GEA 3162 induces apoptosis of neutrophils and bone marrow cells by activating caspase-2/3/8/9 through the ONOO⁻ pathway. GEA 3162 has a bidirectional effect in the rat gastric ulcer model: at low doses, it significantly reduces gastric mucosal damage, while at high doses, it aggravates the ulcer area. GEA 3162 can be used for research on inflammatory conditions such as gastric ulcers .
