An efficient synthesis of 2-amino-5-chloro-3-pyridinecarbox-aldehyde and 5-amino-2-chloro-4-pyridinecarboxaldehyde
摘要:
Efficient synthetic routes to the title compounds 2-amino-5-chloro-3-pyridinecarboxaldehyde (1a) and 5-amino-2-chloro-4-pyridinecarboxaldehyde (1b) are reported. Both compounds are important substrates in the synthesis of naphthyridine derivatives.

Hybridization of structural elements of 1,2,3,5-tetrahydro-2-oxoimidazo[2,1-b]quinazoline ring system common to the cyclic AMP (cAMP) phosphodiesterase (PDE) inhibitors lixazinone (RS-82856, 1) and anagrelide (3) with complementary features of other PDE inhibitor cardiotonic agents prompted the design and synthesis of the title compounds 7a-d, 11, 12, and 13a,b. The necessary features of these compounds
The present invention relates to compounds which inhibit, regulate and/or modulate tyrosine kinase signal transduction, compositions which contain these compounds, and methods of using them to treat tyrosine kinase-dependent diseases and conditions, such as angiogenesis, cancer, tumor growth, atherosclerosis, age related macular degeneration, diabetic retinopathy, inflammatory diseases, and the like in mammals.
Compounds are provided that act as potent antagonists of the CCR2 receptor. Animal testing demonstrates that these compounds are useful for treating inflammation, a hallmark disease for CCR2. The compounds are generally aryl sulfonamide derivatives and are useful in pharmaceutical compositions, methods for the treatment of CCR2-mediated diseases, and as controls in assays for the identification of CCR2 antagonists.

The instant invention provides for compounds that inhibit Akt activity. In particular, the compounds disclosed selectively inhibit one or two of the Akt isoforms. The invention also provides for compositions comprising such inhibitory compounds and methods of inhibiting Akt activity by administering the compound to a patient in need of treatment of cancer.
