近年来研究发现,喹唑啉类化合物具有良好的医药和农药生物活性,是化学界和生物学界研究的热点.医药方面,喹唑啉类化合物早期应用主要为抗疟药[1],但近年来研究热点转换为其在抗肿瘤方面[2-3]和治疗白血病方面[4-5]的应用,并且,喹唑啉类化合物作为α- 受体阻滞剂,在心血管疾病的防治中也占据重要的地位[6-7].当前的热门抗癌药吉非替尼(gefitinib)[8]就是喹唑啉类化合物广阔发展前景的一个缩影. 相似文献

4-苯胺喹唑啉类化合物是一类具有广泛药理活性的喹唑啉类生物碱,在酪氨酸激酶受体(EGFR)抑制剂的研发中具有重要的作用。已经上市的此类药物有吉非替尼(gefitinib)和厄洛替尼(erlotinib)等。此类化合物的合成都是经过喹唑啉酮中间体或直接环合成4-苯胺喹唑啉。苯甲醛及其衍生物被用作反应原料,两种合成路线都要经历对苯甲醛的硝化及硝基的还原两步反应。笔者经查阅资料,设计并验证了以苯胺为原料、经靛红中间体得到4-苯胺喹唑啉类化合物的新的合成路线。本文依据这两种合成策略综述了4-苯胺喹唑啉类化合物的合成方法,并对各种方法的优缺点进行了总结,为进一步研究4-苯胺喹唑啉合成及设计具有药理活性的新化合物提供参考。 相似文献

A simple and easy synthesis of 2‐(3‐nitro‐phenyl)‐quinazoline‐4‐carboxylic acid ( 3 ) has been successfully developed through a one‐pot three‐component condensation reaction of (2‐amino‐phenyl)‐oxo‐acetic acid sodium salt ( 1 ) obtained from the hydrolysis of isatin with ammonium acetate and 3‐nitrobenzaldehyde. Some novel quinazoline‐ester derivatives 4‐7 were then obtained by the reaction between the new compound 3 and various alcohols. Then, quinazoline‐amide derivatives 10‐14 were synthesized from the reaction of various amines and 2‐(3‐nitro‐phenyl)‐quinazoline‐4‐carbonyl chloride ( 8 ), obtained by the reaction of compound 3 with SOCl2. Finally, some novel quinazoline‐azo derivatives 17‐19 were synthesized by the coupling reaction between β‐dicarbonyl compounds and the novel amino‐quinazoline derivative compound 15 , obtained by reduction of nitro‐quinazoline derivative compound 11 . Thus, a new series of quinazoline‐4‐carboxylic acid, ester, amide, and azo derivatives was synthesized and fully characterized by 1H NMR, 13C NMR, IR, and mass spectrometry analysis. 相似文献

A domino synthesis of 5,12-dihydroindolo[2,1-b]quinazoline derivatives via copper-catalyzed Ullmann-type intermolecular C-C and intramolecular C-N couplings is reported. Good yields of various 5,12-dihydroindolo[2,1-b]quinazoline derivatives were obtained. Reaction scopes, limitations, and the reaction mechanism are discussed. 相似文献

Isatoic anhydride has attracted a great deal of attention in recent decades. A review of the methods of preparation of all known quinazoline and quinazolinone derivatives is given herein. Isatoic anhydrides react with some nitrogen nucleophiles, followed by cyclocondensation by electrophiles, to produce several quinazoline and quinazolinone derivatives. These compounds find use as medicinal and pharmacological substances. 相似文献

Fused quinazoline derivatives 1 and 4 react with active methylene compounds and depending on the annelated five-membered ring, two types of transformations have been observed. The 1,3,4-thiadiazolo[3,2-c]quinazoline 1 , underwent the five-membered ring opening reaction to afford the 3,4-dihydroquinazolines 2 in good yields, whereas the 1,3,4-triazolo[3,2-c]quinazoline 4 underwent nucleophilic attack at 2-position of the quinazoline ring to yield the corresponding 1,2,4-triazoles 5 . 相似文献

Expanding our studies on the anti-angiogenesis activities of 2,4-disubstituted quinazoline derivatives [8], a series of novel N-(2-(quinazolin-2-yl)phenyl)benzamide (SZ) derivatives were designed and synthesized. Cytotoxicity assays indicated that most of these compounds displayed similar cytotoxicity against tumor cells in comparison with our previously reported, but showed a higher cytotoxicity against HUVECs. The SZ derivatives showed a remarkable inhibitive effect against the migration and adhesion of HUVECs, in addition to demonstrating significant in vivo anti-angiogenesis activities in the chick embryo chorioallantoic membrane (CAM) assay. The results proved that the introduction of an aryl group with a basic amide side chain on the 4′ position linked to the amide of the C-2 substituted quinazoline scaffold is an effective approach to improve the anti-angiogenic activity of quinazoline derivatives. 相似文献

Some hydrogenation products of 2-hydroxy-4-phenylbenzo [h]quinazoline are acetylated with acetic anhydride. Mono and diacetyl derivatives are obtained, depending on the extent of hydrogenation of the quinazoline ring. From spectroscopic data structures are put forward for these compounds. Formation of a diacetyl derivative from 2-hydroxy-4-phenyl-3, 4, 5, 6-tetrahydrobenzo [h]quinazoline offers support for a previously advanced view regarding its structure.For Part III see [1]. 相似文献
