在室温下,通过酸酐,异氰酸酯或酰氯将2-(2-氨基苯基)喹唑啉-4-胺选择性地酰化在苯基氨基上。在与乙氧基亚甲基衍生物和原酸酯的反应中获得相似的选择性。在温和的条件下,用乙酸酐和异氰酸酯还可以使喹唑啉-喹唑啉四环结构中的环外亚氨基取代基酰化。用浓盐酸(在60°C下1当量)和3 M NaOH(3当量,rt)进行水解以释放苯胺取代基,从而生成甲酰化的衍生物或裂解杂环胺中的酰基。

A molecular switch was developed to recognize and transport Cl− across lipid bilayers. The XRD-crystal structure and NOESY NMR spectra of a potent 4-aminoquinazoline analogue confirmed Cl−-induced conformation changes. Systematic biophysical studies revealed that the quinazoline moiety forms cooperative interactions of H+ and Cl− ions with the thiourea moiety, resulting in the transport of H+/Cl− across
