Synthesis of hydroxy benzoin/benzil analogs and investigation of their antioxidant, antimicrobial, enzyme inhibition, and cytotoxic activities

In this study, hydroxy benzoin (1-7), benzil (8-14), and benzoin/benzil-O-beta-D-glucosides (15-25) were synthesized to investigate their biological activities. An efficient method for synthesizing hydroxy benzoin compounds (1-7) was prepared from four different benzaldehydes using an ultrasonic bath. Then, antioxidant (FRAP, CUPRAC, and DPPH), antimicrobial (3 Gram (-), 4/6 Gram (+), one tuberculosis and one fungus), and enzyme inhibition (acetylcholinesterase, butyrylcholine esterase, tyrosinase, alpha-amylase, and alpha- glucosidase) for the all synthesized compounds (1-25) were evaluated. And also, four most active compounds (4, 12, 18a+b, and 25) from each group were evaluated to the human cervical cancer cell line (HeLa) and anticancer screening tests against the human retinal normal cell line (RPE). Compound 4 showed HeLa and RPE cancer cell activities as much as cisplatin. The synthesized compounds were characterized by spectroscopic methods (NMR, FT-IR, UV, LC-QTOF-MS) and the ACD NMR program's help.

Automated summary

In this study, various organic compounds were synthesized and their biological activities were evaluated, including antioxidant, antimicrobial, and enzyme inhibition. Some compounds showed anti-cancer activity against human cervical cancer cell lines. The synthesized compounds were characterized using spectroscopic methods.
