Glycodendrimer PPI as a Potential Drug in Chronic Lymphocytic Leukaemia. The Influence of Glycodendrimer on Apoptosis in In Vitro B-CLL Cells Defined by Microarrays.

Background: Chronic lymphocytic leukaemia (CLL) cells are characterized by failures in the apoptosis pathway and increased proliferation, resulting in the progressive accumulation of B-lymphocytes in blood. Despite the wide range of antileukaemic drugs, CLL remains an incurable disease. However, a breakthrough is expected which will allow more effective treatment.

The influence of pH and temperature on the stability of N-[(piperidine)methylene]daunorubicin Hydrochloride and a comparison of the stability of daunorubicin and its four new amidine derivatives in aqueous solutions.

The influence of pH and temperature on the stability of N-[(piperidine)methylene]daunorubicin hydrochloride (PPD) was investigated. Degradation was studied using an HPLC method. Specific acid-base catalysis of PPD involves hydrolysis of protonated molecules of PPD catalyzed by hydrogen ions and spontaneous hydrolysis under the influence of water zwitterions, unprotonated molecules, and monoanions of PPD.
