Based on previous work, further search for more effective and less damaging thymidylate synthase (TS) inhibitors was the focus of this study. After further optimization of the structure, in this study, a series of (E)-N-(2-benzyl hydrazine-1-carbonyl) phenyl-2,4-deoxy-1,2,3,4-tetrahydro pyrimidine-5-sulfonamide derivatives were synthesized and reported for the first time. All target compounds were screened by enzyme activity assay and cell viability inhibition assay.

Human epidermal growth factor receptor 2 (HER-2) is an essential member of the receptor tyrosine kinase (RTK) superfamily and has been reported as a critical method for treating HER-2 positive breast cancer. Here, we retained (E)-4-methyl-2-(4-(trifluoromethyl)styryl)oxazole, a fragment of HER-2 inhibitor Mubritinib, and synthesized 32 novel compounds from it. We screened out the most potential compound Q7j with HER-2 positive breast cancer cells through MTT assays, which possessed low toxicity on normal cells (MCF7-10A).

Targeting EGFR and HER-2 is an essential direction for cancer treatment. Here, a series of N-(1,3,4-thiadiazol-2-yl)benzamide derivatives containing a 6,7-methoxyquinoline structure was designed and synthesized to serve as EGFR/HER-2 dual-target inhibitors. The kinase assays verified that target compounds could inhibit the kinase activity of EGFR and HER-2 selectively.

Based on the novel allosteric site of deoxyhypusine synthase (DHPS), two series of 30 novel 5-(2-methoxyphenoxy)-2-phenylpyrimidin-4-amine derivatives as DHPS inhibitors were designed and synthesized. Among them, compound , with the best DHPS inhibitory potency (IC = 0.014 μM), exhibited excellent inhibition against melanoma cells, which was superior to that of GC7.
