Disclosed are compounds of Formula I, including steroisomers, geometric isomers, tautomers, solvates, metabolites and pharmaceutically acceptable salts thereof, that are useful in modulating PIKK related kinase signaling, e.g., mTOR, and for the treatment of diseases (e.g., cancer) that are mediated at least in part by the dysregulation of the PIKK signaling pathway (e.g., mTOR).
The present invention provides an agent for the prophylaxis or treatment of autoimmune diseases (e.g., psoriasis, rheumatoid arthritis, inflammatory bowel disease, Sjogren's syndrome, Behcet's disease, multiple sclerosis, systemic lupus erythematosus etc.) and the like, which has a superior Tyk2 inhibitory action.
The present invention relates to a compound represented by the formula
wherein each symbol is as defined in the specification, or a salt thereof.
The catalytic deuterodechlorination of aryl/heteroaryl chlorides was developed with a palladium/unsymmetrical NHC system, and the precisely controlled introduction of deuterium into a variety of aryl/heteroaryl compounds was achieved with a high level of efficiency, selectivity, and deuteration degree. This method was also successfully applied to the transformation of bioactive agents even in a gram-scale
Heterocyclic compounds of the formula ##STR1## wherein Het denotes optionally substituted pyridazinyl, pyrimidinyl, pyrazinyl or substituted pyridyl, R.sub.1 is hydrogen or methyl and R.sub.2 is lower alklyl, optionally substituted phenyl-lower alkyl, carboxy-lower alkyl or functionally modified carboxy-lower alkyl, their condensation products with aldehydes, ketones or carbonic acid and their N-oxides, which are valuable (cardioselective) .beta.-receptor blocking agents, and/or (cardioselective) .beta.-receptor-stimulants.
