A general and efficient synthesis of some new 3,5-disubtituted 1,4-benzoxazine-pyrazole hybrids (4a-4n) in eco-friendly water via a tandem Sonogashira coupling and cyclocondensation sequence from aromatic acid chlorides, 3-(3-oxo-2H-benzo[b][1,4]oxazin-4(3H)-yl)propanenitrile, and hydrazine hydrate was reported herein. Among them, the compounds 4c and 4n showed comparable activity against four human
通过芳族酰氯的串联 Sonogashira 偶联和环缩合序列,3-(3-氧代) 在环保水中普遍有效地合成一些新的 3,5-二取代 1,4-苯并恶嗪-吡唑杂化物 ( 4a-4n )本文报道了-2 H-苯并[ b ][1,4]oxazin-4(3 H )-基)丙腈和水合肼。其中,化合物4c和4n与标准依托泊苷对四种人类癌细胞系如 MCF-7(乳腺癌)、A549(肺)、HeLa(宫颈)和 PC3(前列腺)显示出相当的活性。此外,化合物4b 、4e、4i和4j 与依托泊苷相比,对所有细胞系都表现出有希望的活性。此外,与标准厄洛替尼相比,化合物4c和4n对酪氨酸激酶 EGFR 显示出有希望的抑制活性。两种最有效的类似物4c和4n的计算机药代动力学和对接研究结果也支持一致的体外抗癌活性结果。
