| titleOfInvention | 2-acetamido-2-deoxy-0-beta-D-glukopyranosides and 2 acetamido-2-deoyy-0-beta-D-galactopyranosides of ergot alkaloids and process of their preparation |
| abstract | In the present invention there are disclosed 2-acetamido-2-deoxy-O-{beta}-D-glucopyranosides and 2-acetamido-2-deoxy-O-{beta}-D-galactopyranosides of ergot alkaloids - elymoclavine lysergol, 9,10 dihydrolysergol of the general formula I, chanoclavine of the general formula II and ergometrine of the general formula III, in which R = Ri1 or Ri2. Said compounds are prepared in such a manner that elymoclavine lysergol, l9,10-dihydrolysergol, chanoclavine or ergometrine is treated with N-acetylhexosaminidase in the presence of p-nitrophenyl-{beta}-N-acetylgalactosaminide or p-nitrophenyl-{beta}-N-acetylglucosaminide in buffer solution with pH value ranging from 4 to 7 at a temperature in the range of 4 to 35 degC, whereupon the obtained product is isolated for instance by silica gel chromatography of by high-efficient liquid chromatography. |
