Biochem/physiol Actions

Aclidinium bromide is a long-acting muscarinic antagonist (LAMA) bronchodilator. It is a muscarinic M3, M2 antagonist with a long residence time at M3 receptors and a shorter residence time at M2 receptors. Aclidinium bromide was approved for the treatment of chronic obstructive pulmonary disease (COPD) in July 2012.

Aclidinium bromide is a novel potent, long-acting inhaled muscarinic antagonist in development for the treatment of chronic obstructive pulmonary disease. Aclidinium showed subnanomolar affinity for the five human muscarinic receptors (M(1)-M(5)). [(3)H]Aclidinium dissociated slightly faster from M(2) and M(3) receptors

Osteosarcoma is recognized as the most common primary malignant bone tumor, the 5-year disease-free survival rate in patients with metastatic or recurrent disease is below than 30%. Drug resistance and toxic side effects limit the therapeutic efficacy of osteosarcoma. Therefore

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
