The receptor tyrosine kinase rearranged during transfection (RET) plays pivotal roles in several cancers, including thyroid carcinoma and non-small cell lung cancer (NSCLC). Currently, there are several FDA-approved RET inhibitors, but their indication is limited to thyroid cancer, and none can overcome their gatekeeper mutants (V804L and V804M). Here, we report the discovery of 9x representing a new chemotype of potent and selective RET inhibitors, using a rational design strategy of type II kinase inhibitors. 9x exhibited both superior antiproliferative activities against NSCLC-related carcinogenic fusions KIF5B-RET and CCDC6-RET and gatekeeper mutant-transformed Ba/F3 cells, with the lowest GI50 of 9 nM, and substantial inhibitory activities against wild-type RET and RET mutant proteins, with the best IC50 of 4 nM. More importantly, 9x also showed nanomole potency against RET-positive NSCLC cells LC-2/ad, but not against a panel of RET-negative cancer cells, such as A549, H3122, A375 or parental Ba/F3 cells, demonstrating its selective ‘on-target’ effect. In mouse xenograft models, 9x repressed tumor growth driven by both wild type KIF5B-RET-Ba/F3 and gatekeeper mutant KIF5B-RET(V804M)-Ba/F3 cells in a dose-dependent manner. Together, these data establish that 9x provides a good starting point for the development of targeted therapeutics against RET-positive cancers, especially NSCLC.

In order to find novel nonsteroidal compounds possessing an inhibitory activity against delayed-type hypersensitivity (DTH) reactions, we conducted random screening using a picryl chloride (PC)-induced contact hypersensitivity reaction (CHR) in mice, and found compound 1 as a lead compound. Then we synthesized and evaluated an extensive series of 5-carboxamidouracil derivatives focused on both the uracil and the antioxidative moieties. Among them, we found that the hindered phenol moiety was necessary to exhibit the activities; especially, compounds 28a-28c having the partial structure of vitamin E were found to exert potent activities against the DTH reaction by both oral and topical administration. And compound 28c showed antioxidative activity against lipid peroxidation with an IC50 of 5.9μM. Compound 28c (CX-659S) was chosen as a candidate drug for the treatment of cutaneous disorders such as atopic dermatitis and allergic contact dermatitis. Copyright (C) 2000 Elsevier Science Ltd.
