Despite various applications of kinase inhibitors in oncology and inflammatory diseases, the emergence of resistance still remains the major barrier to achieve long-term remission in cancer treatment. With the aim of overcoming the resistance induced by type IIB BRaf V600E selective inhibitor vemurafenib, and further ameliorating the antiproliferative activity, a novel type IIA Pan-Raf inhibitors Ia–Io based on pyrrolo[2,3-d] pyrimidine scaffold were designed and evaluated in this work. Herein, we tried to improve the cellular potency of the target compounds by increasing their solubility. Among them, Il, with the solubility of 0.107 mg/mL, demonstrated favorable cellular activity against vemurafenib-resistant carcinoma cells including BRafWT phenotypic melanoma SK-MEL-2 and BRafV600E phenotypic colorectal cancer HT-29 cell lines. Based on the well solubility, Il exhibited good metabolic stability compared to sorafenib and showed favorable pharmacokinetic profiles in rats. As for the biological mechanism research, Il had the similar P-ERK kinase inhibitory activity in A375 and SK-Mel-2 cells as our previously lead P-2. Il may become a good candidate compound to overcome the resistance associated with vemurafenib.

Simutaneous targeting all Raf isoforms offers the prospect of enhanced efficacy as well as reduced potential for resistance. Described herein is the discovery and characterization of a series of pyrimidine scaffold with DFG-out conformation as potent Pan-Raf inhibitors. Among them, I-41 with excellent Pan-Raf potency demonstrates inhibitory activity against BRafWTphenotypic melanoma and BRafV600Ephenotypic colon cells. The western blot results for the Erk inhibition in human melanoma SK-Mel-2?cell lines showed I-41 inhibited the proliferation of SK-Mel-2?cell lines without paradoxical activation of Erk, which supported I-41 may become a good candidate compound to overcome the resistance of melanoma against the current BRafV600Einhibitor therapy. I-41 also have a favorable pharmacokinetic profile in rat. Synthesis, SAR, lead selection, and evaluation of the key compounds studies are described.

Selective BRafV600E inhibitors with DFG-in conformation have been proven effective against a subset of melanoma. However, representative inhibitor vemurafenib rapidly acquires resistance in the BRafWT cells through a CRaf or BRafWT dependent manner. Simultaneous targeting of all subtypes of Raf proteins offers the prospect of enhanced efficacy as well as reduced potential for acquired resistance. Herein, we describe the design and characterization of a series of compounds I-01-I-22, based on a pyrimidine scaffold with DFG-out conformation as Pan-Raf inhibitors. Among them, I-15 binds to all Raf protomers with IC50 values of 12.6 nM (BRafV600E), 30.1 nM (ARaf), 19.7 nM (BRafWT) and 17.5 nM (CRaf) and demonstrates cellular activity against BRafWT phenotypic melanoma and BRafV600E phenotypic colorectal cancer cells. The western blot results for the P-Erk inhibition in human melanoma SK-Mel-2 cell line showed that I-15 inhibited the proliferation of the SK-Mel-2 cell line at concentrations as low as 400 nM, without paradoxical activation of Erk as vemurafenib, which supported that I-15 may become a good candidate compound to overcome the resistance of melanoma induced by vemurafenib. I-15 also has a favorable pharmacokinetic profile in rats. Rational design, synthesis, SAR, lead selection and evaluation of the key compounds studied are described.

The invention relates to the use of diaryl urea derivatives for the manufacture of pharmaceutical compositions for the treatment of RET dependent disorders, especially RET dependent tumor diseases. The invention further relates to novel N-[4-(pyrimidin-4-yloxy)-phenyl]-N’-phenyl-urea derivatives and their use in the treatment of the animal or human body, especially in the treatment of a protein kinase dependent disease, to pharmaceutical compositions comprising such novel N-[4-pyrimidin-4-yloxy)-phenyl]-N’-phenyl-urea derivatives and to the use of such novel N-[4-(pyrimidin-4-yloxy)-phenyl]-N’-phenyl-urea derivatives for the preparation of pharmaceutical compositions for use in the treatment of protein kinase dependent diseases, especially of proliferative diseases, such as tumour diseases.
