摘要: 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 pyrazole with phosphodiesterase-3 (PDE-3) inhibitory action, vasorelaxant activity low toxicity catalyzed by filamentous fungi biofilm in bioreactor was successfully developed. A maximum N-glycosyl yield 68% obtained Cunninghamella echinulata ATCC 9244 conditions 25mgml(-1) 1 PDSM medium at 28°C 96h. After extraction ethyl acetate, the identified Ultrahigh Resolution Mass Spectrometry (1)H-(13)C HSQC/HMBC.
