Scientists from Fu Wai Hospital of the Chinese Academy of Medical Sciences and Shenzhen Bay Laboratory have divulged cAMP-specific 3',5'-cyclic phosphodiesterase 4B (PDE4B) inhibitors. They are reported to be useful for the treatment of autoimmune diseases, cancer, neurological disorder, diabetes, inflammatory bowel disease, pulmonary fibrosis, psoriasis and arthritis, among others.
Apex Biosciences Pte Ltd. has identified phosphodiesterase PDE4B inhibitors reported to be useful for the treatment of cancer, neurological disorders, inflammatory bowel disease, skin inflammation, lung inflammation, eye inflammation and inflammatory joint diseases.
Ulcerative colitis is a chronic, immune-mediated disorder of the colon and rectum characterized by mucosal inflammation that damages the bowel wall surface. Current therapeutic options include 5-aminosalicylates, corticosteroids or anti-TNF agents, but there is a need for new strategies to obtain higher remission rates and less systemic immunosuppression.
CSPC Pharmaceutical Group Ltd. has obtained clearance from China’s National Medical Products Administration (NMPA) to conduct clinical trials in China of SYH-2059 tablets for interstitial lung disease, including idiopathic pulmonary fibrosis and progressive pulmonary fibrosis.
Work at Innovstone Therapeutics Ltd. has led to the identification of new dihydrothienopyrimidine derivatives acting as phosphodiesterase PDE4B inhibitors.
A Tibet Haisco Pharmaceutical Co. Ltd. patent describes new phosphodiesterase PDE4B inhibitors potentially useful for the treatment of cancer, chronic obstructive pulmonary disease and idiopathic pulmonary fibrosis.
Humanwell Healthcare (Group) Co. Ltd. has disclosed compounds acting as phosphodiesterase PDE4 inhibitors, particularly PDE4B, reported to be useful for the treatment of respiratory, gastrointestinal, inflammatory, dermatological, ophthalmic and neurological disorders, transplant rejection and cancer.
Psychiatric indications, such as depression, schizophrenia and bipolar disorder, share a common feature of elevated expression of pro-inflammatory markers in the periphery and/or central nervous system. Based on this, it is believed that combined immuno- and neuromodulatory activities of phosphodiesterase 4 (PDE4) inhibitors may represent a promising new therapeutic strategy for various psychiatric indications.
