Herein, we describe the synthesis and SAR of a series of small molecule macrocycles that selectively inhibit JAK2 kinase within the JAK family and FLT3 kinase. Following a multiparameter optimization of a key aryl ring of the previously described SB1518 (pacritinib), the highly soluble 141 was selected as the optimal compound. Oral efficacy in the murine collagen-induced arthritis (CIA) model for rheumatoid arthritis (RA) supported 141 as a potential treatment for autoimmune diseases and inflammatory disorders such as psoriasis and RA. Compound 141 (SB1578) was progressed into development and is currently undergoing phase 1 clinical trials in healthy volunteers.

[EN] The present invention relates to pyridyl substituted pyrimidine compounds that are useful as agents for the treatment of kinase related disorders such as proliferative disorders. More particularly, the present invention relates to oxygen linked and pyridyl substituted pyrimidine compounds, methods for their preparation, pharmaceutical compositions containing these compounds and uses of these compounds in the treatment of proliferative disorders. These compounds may be useful as medicaments for the treatment of a number of kinase related disorders such as proliferative disorders including tumours and cancers as well as other disorders or conditions related to or associated with kinases. [FR] La présente invention porte sur des composés de pyrimidine à substitution pyridyle qui sont utiles en tant qu'agents pour le traitement de troubles liés à la kinase, tels que des troubles prolifératifs. Plus particulièrement, la présente invention porte sur des composés de pyrimidine liés à l'oxygène et à substitution pyridyle, sur des procédés pour leur préparation, sur des compositions pharmaceutiques contenant ces composés et sur des utilisations de ces composés dans le traitement de troubles prolifératifs. Ces composés peuvent être utiles en tant que médicaments pour le traitement d'un certain nombre de troubles liés à la kinase, tels que des troubles prolifératifs comprenant les tumeurs et les cancers ainsi que d'autres troubles ou états liés ou associés aux kinases.
