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.

experimental part, p. 27 - 38 (2012/07/01)
Privileged structures like Benzothiazole and Pyrrolobenzodiazepine offer wonderful opportunity to explore in anti-cancer drug discovery as a mean to counter drug-resistance problem. BT-PBD hybrids and diverse BT derivatives have been synthesized and their in vitro cytotoxic activities were screened against five cancer cell lines have been discussed. The novel compounds showed promising results as compared with the marketed drug etoposide and could well be used in future anti-cancer drug development studies.
