Design, synthesis and biological evaluation of novel quinazoline derivatives as potential antitumor agents: Molecular docking study
摘要:
Novel derivatives of quinazoline (1-27) have been synthesized and tested for their antitumor activity against three tumor cell lines among these cell lines the human breast carcinoma cell line (MCF-7) in which EGFR is highly expressed. All tested compounds showed potent and selective activity against breast cancer (MCF-7) with IC50 range of 3.35-6.81 mu g/ml. With regarding broad-spectrum activity compounds 5, 9, 15, 18 and 20 exploited potent antitumor against human liver cell line (HEPG2), human breast cell line (MCF-7) and human cervix cell line (HELA) with IC50 range of 3.35-5.59 mu g/ml. Virtual screening was carried out through docking the designed compounds into the ATP binding site of epidermal growth factor receptor (EGFR) to predict if these compounds have analogous binding mode to the EGFR inhibitors.

Direct activation of sp2 C–H bonds by a palladium catalyst has received significant attention in organic chemistry. However, most of these C–Hactivation reactions are carried out in hazardous solvents. Herein we report a novel solvent-free direct sp2 C–Hbond functionalization (oxygenation) method using Pd(II)/Al2O3 catalysis of oxo-benzoxazine derivatives with good to excellent yields, and demonstrate
钯催化剂直接活化sp 2 C-H键在有机化学中受到了广泛关注。然而,大多数这些 C-H 活化反应是在危险溶剂中进行的。在此,我们报道了一种使用 Pd( II )/Al 2 O 3催化氧代苯并恶嗪衍生物的新型无溶剂直接 sp 2 C-H 键官能化(氧化)方法,并证明了其在合成药学上重要的化合物。

A novel series of 6-chloro-2-p-tolylquinazolinone and substituted-(4-methylbenzamido)benzamide (1–20) were designed, synthesized and evaluated for their in-vitro antitumor activity. Compounds 3, 14 and 16 possessed remarkable broad-spectrum antitumor activity. Compound 16 was found to be a particularly active growth inhibitor of the renal cancer (GI50 = 4.07 μM), CNS cancer (GI50 = 7.41 μM), ovarian
