Abstract

•An efficient and rapid process for N-glycosylation of 5-(1-(3-fluorophenyl)-1H-pyrazol-4-yl)-2H- tetrazole.•Filamentous fungi biofilm in bioreactor was successfully developed.•N-Glycosyl yield of 68% was obtained with Cunninghamella echinulata ATCC 9244 biofilm in bioreactor.

An efficient and rapid process for N-glycosylation of 5-(1-(3-fluorophenyl)-1H-pyrazol-4-yl)-2H-tetrazole—LQFM 021 (1), a new synthetic derivative of pyrazole with phosphodiesterase-3 (PDE-3) inhibitory action, vasorelaxant activity and low toxicity catalyzed by filamentous fungi biofilm in bioreactor was successfully developed. A maximum N-glycosyl yield of 68% was obtained with Cunninghamella echinulata ATCC 9244 biofilm in bioreactor with conditions of 25 mg ml−1 of 1 in PDSM medium at 28 °C for 96 h. After extraction with ethyl acetate, the derivative was identified by Ultrahigh Resolution Mass Spectrometry and 1H–13C HSQC/HMBC.
