Description

Application

• Reactant for preparation of substituted indole derivatives as histamine H3 antagonists
• Reactant for preparation of potent and selective inhibitors of human reticulocyte 15-lipoxygenase-1
• Reactant for preparation of inhibitors of Gli1-mediated transcription in Hedgehog pathway
• Reactant for preparation of pyridinyl carboxylates as SARS-CoV 3CL proinhibitors
• Reactant for preparation of substituted bipiperidinylmethyl amides as CCR3 membrane binding ligands
• Reactant for preparation of indole amide hydroxamic acids as potent inhibitors of histone deacetylases
