Title: Pyrimidine derivative inhibiting growth of cancer cell and medicinal use thereof

Description:
TECHNICAL FIELD 
     The present invention relates to pyrimidine derivative compounds effective for inhibiting growth of cancer cells and anti-cancer uses thereof. 
     BACKGROUND ART 
     Various mutations in the kinase domain of epidermal growth factor receptor (EGFR) are found as oncogenic genes in patients with non-small cell lung cancer, and Gefitinib, Erlotinib, Osimertinib, and the like are used as a small molecule kinase inhibitor for the epidermal growth factor receptor (EGFR) to treat them. 
     Among them, lung cancer caused by an insertion in exon 20 of EGFR mutation (EGFR EXON 20 Insertion mutation) accounts for 5% of all mutations, and various epidermal growth factor receptor inhibitors (EGFR inhibitors) have been evaluated for its treatment, but there is still no drug approved as a standard therapy for treatment of EGFR EXON 20 Insertion mutation lung cancer, so there is an urgent need to develop a drug that can treat this.

     EXPERIMENTAL EXAMPLE 1: MEASUREMENT OF INHIBITORY EFFECT ON CANCER CELL GROWTH 
     Since lung cancer cell line having an EGFR insertion mutation cannot be available commercially, a method for inserting 3-4 amino acids at each site in a wild type EGFR expression vector using site direct mutagenesis was attempted. First, the present invention used a vector in which NPG of 3 amino acids were added to D770_N771 site of the most frequent alterations, and used the Ba/F3 cell line for expression of these genes. The Ba/F3 cell line is Murine IL3-dependent pro B cell line showing cell growth only when IL-3 is added, and has mutant EGFR dependency on cell growth and death in an absence of IL-3, when an oncogenic mutant EGFR is expressed. Because substances showing effective inhibitory effect on the mutant EGFR inhibit cell growth and induce apoptosis, the anti-cancer effect on cells was analyzed by MTT assay. 
     Pre-constructed stable cells of 1×10 4  cells were placed in a 96 well plate and incubated overnight, and then the compounds of Examples were treated at a dose dependent manner After 72 hours, MTT reagent was added, and after 3 hours, stop buffer (10% SDS) was added. After 24 hours of incubation, the result was analyzed by reading at 595 nm, and the IC 50  value was calculated at a concentration where each compound inhibited cell growth by 50%. The result was shown as A, B, C, and D in Table 1 below. Herein, A means IC 50 ≤100 nM, and B means IC 50 =100-300 nM, and C means IC 50 =300-1,000 nM, and D means IC 50 &gt;1,000 nM. As a control drug, Osimertinib was used.

     As shown in Table 1, the compounds according to the present invention exhibited excellent activity to lung cancer cell line expressing the EXON 20 Insertion mutation of epidermal growth factor receptor. In particular, the activity of Examples 10-17 compounds was more excellent. On the other hand, the activity of the control drug, Osimertinib was relatively weak. 
     Accordingly, the present invention suggests a novel pyrimidine derivative which can treat lung cancer expressing the EXON 20 Insertion mutation in the epidermal growth factor receptor.
