The antiproliferative activities of the seven 2,3-dihydroquinazolin-4(1H)-one analogues (C1–C7) against PC3 (green) and DU145 (blue) cell lines. (A–G) refer to C1, C2, C3, C4, C5, C6 and C7, respectively. Significance between two cell line is expressed as ^*P-value ≤ 0.05, ^**P-value ≤ 0.01 (Student’s independent t-test).
