neuraminidase, unlike sialic acid and oseltamivir in molecular docking studies. All molecules reduced the viral titer and exhibited non-cytotoxicity along with cryo-protective property towards MDCK cells. Molecules (Z)-2-(3′-Chloro-benzylidene)-1,2-dihydro-indol-3-one (2f), (Z)-2-(4′-Chloro-benzylidene)-1,2-dihydro-indol-3-one (2g) and 2-(2′-Methoxy-phenyl)-1H-quinolin-4-one (3a) were the most interesting
一系列支架,即 aurones、3-indolinones、4-quinolones 和肉桂酸-哌嗪杂化物,被设计、合成并在体外针对 A/H1N1pdm09 病毒进行了研究。与分子对接研究中的唾液酸和奥司他韦不同,设计的分子采用不同的结合方式,即在神经氨酸酶的430-cavity中。所有分子都降低了病毒滴度并表现出非细胞毒性以及对 MDCK 细胞的冷冻保护特性。分子 ( Z )-2-(3'-Chloro-benzylidene)-1,2-dihydro-indol-3-one ( 2f ), ( Z )-2-(4'-Chloro-benzylidene)-1,2- dihydro-indol-3-one ( 2g ) 和 2-(2'-Methoxy-phenyl)-1H-quinolin-4-one ( 3a) 是本研究中鉴定出的最有趣的分子,与参考竞争性和非竞争性抑制剂相比,奥司他韦 (EC
