Abstract
A series of novel diaminopyrimidines containing pinane moieties were synthesized via an efficient methodology starting from pinane-based aminoalcohols, aminodiols and 2,4-dichloropyrimidines. Bioassay tests demonstrated that compound 18a displayed much stronger antiproliferative activities against four human cancer cell lines (HeLa, Siha, MDA-MB-231, MCF-7 and A2780) than positive control cisplatin. In particular, compound 22a was found to be selective in inhibiting HeLa cell proliferation with cancer cell growth inhibition values higher than 95 %. Moreover, the in vitro screening of prepared compounds against different bacterial and fungal strains is reported. The results revealed that 12b and 17a, the most promising compounds, displayed selective inhibition for the Gram-positive bacteria (B. subtilis and S. aureus) with percent inhibition values ranging from 75 to 95 % at 10 μg/mL concentration. Both selective inhibition and the in vitro activity values demonstrated that these compounds have the potential to be developed into clinically important therapeutic choices for the treatment of infections caused by B. subtilis and S. aureus.

Abstract
Janus kinases (JAKs) are non-receptor tyrosine kinases that are essential components of the JAK-STAT signaling pathway. Associated aberrant signaling is responsible for many forms of cancer and disorders of the immune system. The present focus is on the discovery of molecules that may regulate the activity of JAK2 by selective binding to the JAK2 pseudokinase domain, JH2. Specifically, the Val617Phe mutation in JH2 stimulates the activity of the adjacent kinase domain (JH1) resulting in myeloproliferative disorders. Starting from a non-selective screening hit, we have achieved the goal of discovering molecules that preferentially bind to the ATP binding site in JH2 instead of JH1. We report the design and synthesis of the compounds and binding results for the JH1, JH2, and JH2 V617F domains, as well as five crystal structures for JH2 complexes. Testing with a selective and non-selective JH2 binder on the autophosphorylation of wild-type and V617F JAK2 is also contrasted.
