27 Authors, 586 pages, a whole bunch of examples, and 20 MB of Jak-2 goodness.


Seems likely that XL-019 came out of this series.

The news today is that LS-104 is in Ph1 and now owned by Aegera from Lymphosign who in turn licsensed it from HSC. Their portfolio of patent applications suggests the compound is likely a tyrphostin derivative.

LS104 is a novel small molecule tyrosine kinase inhibitor of therapeutically significant kinases including Jak2 and Bcr-Abl…In contrast to marketed kinase inhibitor drugs, LS104 inhibits its targets in a non-ATP-competitive manner



I don’ t know about you but I needed a history lesson to get a handle on these

Pfizer’s Jak3 inhibitor CP-690,550 was described earlier listed as Ph ii-iii. For some reason that was changed, and all of its furthest advanced trials are Phase 2.
