As the critical driving force for chronic myeloid leukemia (CML), BCR gene fused ABL kinase has been extensively explored as a validated target of drug discovery. Although imatinib has achieved tremendous success as the first-line treatment for CML, the l

The invention relates to a spiro derivative, a preparation method thereof and application of the spiro derivative in medicine. Specifically, the invention relates to the spiro derivative shown in a general formula (I), the preparation method thereof, a pharmaceutical composition containing the spiro derivative and application of the spiro derivative as a therapeutic agent, especially application of the spiro derivative as an RAF inhibitor and application of the spiro derivative in preparation of drugs for treating or preventing various diseases (including cancers) related to over-expression RAF activity.

Pharmacological targeting of tumor associated macrophages and microglia in the tumor microenvironment is a novel therapeutic strategy in the treatment of glioblastoma multiforme. As such, the colony stimulating factor-1 receptor (CSF-1R) has been identified as a druggable target. However, no validated companion diagnostic marker for these therapies exists to date. Towards development of a CSF-1R PET tracer, a set of six compounds based on recently reported CSF-1R inhibitor 5-(1-methyl-1H-pyrazol-4-yl)-N-(2-methyl-5-(3-(trifluoromethyl)benzamido)phenyl)nicotinamide (Compound 5) was designed, synthesized and evaluated in vitro for potency and selectivity. The highest affinity for CSF-1R was found for compound 5 (IC50: 2.7 nM). Subsequent radiosynthesis of [11C]5 was achieved in 2.0 ± 0.2% yield (decay corrected to start of synthesis) by carbon-11 carbon monoxide aminocarbonylation in 40 min after end of bombardment. In vitro autoradiography with [11C]5 on rat brain sections demonstrated high specific binding, but also strong off-target binding. Ex vivo, only intact tracer was observed in blood plasma at 90 min post injection in healthy rats. PET scanning results demonstrated negligible brain uptake under baseline conditions and this brain uptake did not increase by blocking of efflux transporters using Tariquidar. To conclude, [11C]5 was successfully synthesized and evaluated in healthy rats. However, the inability of [11C]5 to cross the blood-brain-barrier excludes its use for imaging of CSF-1R expression in the brain.
