AZD1446tosylate, also known as TC-6683, is a novel highly selective α4β2 nicotinic acetylcholine receptor agonist for the treatment of cognitive disorders. AZD1446tosylate showed favorable pharmaceutical properties and in vivo efficacy in animal models has been identified as a potential treatment for cognitive deficits associated with psychiatric or neurological conditions and had been evaluated in phase 2 clinical trials as a treatment for Alzheimer's disease.
NL-103 is a novel dual-targeted inhibitor of histone deacetylases and hedgehog pathway, effectively overcomes vismodegib resistance conferred by Smo mutations. NL-103 comprises structural elements of Hh pathway inhibitor vismodegib, and histone deacetylase (HDAC) inhibitor vorinostat. NL-103 simultaneously and significantly inhibited both HDACs and Hh pathway. Importantly, NL-103 effectively overcame vismodegib resistance induced by Smoothened point mutations. Moreover, NL-103 significantly downregulated the expression of Gli2 which plays an important role in Hh pathway. NL-103 may be a promising compound for clinical development as a more effective Hh pathway inhibitor.
