A series of bezofuran appended 1,5-benzothiazepine compounds 7a–v was designed, synthesized and evaluated as cholinesterase inhibitors. The biological assay experiments showed that most of the compounds displayed a clearly selective inhibition for butyrylcholinesterase (BChE), while a weak or no effect towards acetylcholinesterase (AChE) was detected. All analogs exhibited varied BChE inhibitory activity with IC₅₀ value ranging between 1.0 ± 0.01 and 72 ± 2.8 μM when compared with the standard donepezil (IC₅₀, 2.63 ± 0.28 μM). Among the synthesized derivatives, compounds 7l, 7m and 7k exhibited the highest BChE inhibition with IC₅₀ values of 1.0, 1.0 and 1.8 μM, respectively. The results from a Lineweaver-Burk plot indicated a mixed-type inhibition for compound 7l with BChE. In addition, docking studies confirmed the results obtained through in vitro experiments and showed that most potent compounds bind to both the catalytic anionic site (CAS) and peripheral anionic site (PAS) of BChE active site. The synthesized compounds were also evaluated for their in vitro antibacterial and antifungal activities. The results indicated that the compounds possessed a broad spectrum of activity against the tested microorganisms and showed high activity against both gram positive and gram negative bacteria and fungi.

一系列bezofuran的所附1,5-苯并硫氮杂化合物7A-V被设计，合成和评价为胆碱酯酶抑制剂。生物学测定实验表明，大多数化合物对丁酰胆碱酯酶（BChE）表现出明显的选择性抑制作用，而对乙酰胆碱酯酶（AChE）的作用却微弱或没有。与标准多奈哌齐相比，所有类似物均表现出不同的BChE抑制活性，IC ₅₀值在1.0±0.01至72±2.8μM之间（IC _50为2.63±0.28μM）。在合成衍生物中，化合物7l，7m和7k对IC _50的BChE抑制作用最高分别为1.0、1.0和1.8μM。Lineweaver-Burk图的结果表明化合物7l与BChE的混合型抑制作用。此外，对接研究证实了通过体外实验获得的结果，并表明大多数有效化合物均与BChE活性位点的催化阴离子位点（CAS）和外围阴离子位点（PAS）结合。还评估了合成的化合物的体外抗菌和抗真菌活性。结果表明该化合物对被测微生物具有广谱的活性，并且对革兰氏阳性和革兰氏阴性细菌和真菌均具有高活性。
