The present invention relates to 2-arylamino-4-(heterocyclic)aminopyrimidines inhibitors which are inhibitors and therefore inhibit Protein Kinase C-alpha (PKC-α). The PKC-α inhibitors of the present invention are important for improving myocardial intracellular calcium cycling, resulting in improved myocardial contraction and relaxation performance and thereby slowing the progression of heart failure. The present invention further relates to compositions comprising said 2-arylamino-4-(heterocyclic)amino-pyrimidines and to methods for controlling, abating, or otherwise slowing the progression of heart failure.

The present invention concerns novel pharmaceutically active triterpene amine derivatives, pharmaceutical compositions containing the same, their use as medicaments, and the use of the compounds for the manufacture of specific medicaments. The present invention also concerns a method of treatment involving administration of the triterpene amine compounds. Specifically, the compounds are derivatives of betulinic acid having substitutions at one or more of the C-3, C-28 and C-19 positions as further described herein. The novel compounds are useful as antiretroviral agents. In particular, the novel compounds are useful for the treatment of Human Immunodeficiency Virus-1 (HIV-1).

A bottleneck in fragment-based lead development is the lack of systematic approaches to elaborate the initial fragment hits, which usually bind with low affinity to their target. Herein, we describe an analysis using X-ray crystallography of a diverse library of compounds prepared using microscale parallel synthesis. This approach yielded an 8-fold increase in affinity and detailed structural information for the resulting complex, providing an efficient and broadly applicable approach to early fragment development.
