[Research concerning rutin semisynthetic derivatives, synthesis and pharmaco-toxicological properties of some new morpholine and piperidine derivatives].
2003
In order to continue the research of the rutin semisynthetic derivatives we obtained some new morpholine and piperidine derivatives. Melting points, solubility, yield, C, H, N elemental analysis and UV spectra characterised all of these compounds. The toxicity was established by intraperitoneal administration at mice; the values of LD50 are between 743.75 and 856.25 mg/kg (medium toxicity). Pharmacological assays included the following parameters: leukocytes formula, NBT test, and serum complement activity. The new derivatives of rutin have a very good solubility in water, a pH closed to physiological value and immunosuppressive activity: peripheric blood PMN and lymphocytes are decreased; fagocytic capacity of peripheric blood PMN is also decreased; serum complement activity is not changed.
