T buňky mají zásadní úlohu při vytvoření protinádorové imunity u myší léčených protilátkou směrovanými konjugáty doxorubicinu a HPMA

Anti-idiotype monoclonal antibody targeted N-(2-hydroxypropyl)methacrylamide copolymer bound doxorubicin is able to completely cure mice with BCL-1 B-cell leukemia. During the treatment the immune system is activated and effective long-term anti-tumor immunity is established. This immune reaction requires CD4+ and CD8+ cells.
Antracyklinová antibiotika na bázi protilátkou směrovaného HPMA

Conjugates based on N-(2-hydroxypropyl)methacrylamide represent a new generation of polymeric anticancer drugs with improved therapeutic potential and considerably decreased nonspecific side effects. Antibody -targeted derivatives show specific active targeting and nonspecific passive accumulation in solid tumors.
Exprese genů pro signalizaci apoptozy u buněk vystavených účinku HPMA konjugátů doxorubicinu
Kovář, Lubomír ; Kovář, Marek ; Šťastný, Marek ; Strohalm, Jiří ; Etrych, Tomáš ; Ulbrich, Karel ; Říhová, Blanka
We compared influence of hydrolytically and enzymatically cleavable conjugates based on N-(2-hydroxypropyl)methacrylamide on proliferatin activity and expression of mRNA of genes involved in apoptotic signalling pathway. We found elevated expression of Fas and bax mRNA in cells incubated with hydrolytically cleavable conjugates.
Mechanismus působení polymerních léčiv na bázi HPMA
Hovorka, Ondřej ; Strohalm, Jiří ; Bouček, Jan ; Etrych, Tomáš ; Šubr, Vladimír ; Ulbrich, Karel ; Říhová, Blanka
However cytostatic polymeric conjugates based on N-(2-hydroxypropyl)methacrylamide are in clinical trials, we are still far away from understanding the mechanism of their action. Cleavability of the drug from oligopeptidic side-chains of polymeric carriers seems not to be necessary condition for pharmacological activity and those spacers play most probably a very important role in the accumulation of conjugates in tumor cells.
Protinádorová směrovaná léčba na bázi HPMA: základní principy pro syntézu konjugátů a převod z laboratoře do kliniky

Conjugates of N-(2-hydroxypropyl)methacrylamide with doxorubicin containing human IVIg were used for palliative treatment in patients with advanced cancer. More thena 116 biochemical and immunological parameters were tested. A decrease of some parameters with patological values was seen, and physiological values were occasionally reached, including some TAA.
Směrovaná polymerní léčiva
Říhová, Blanka
Unwanted side effect of anticancer treatment could be eliminated by affinity therapy. It is necessary to find targeting system which deliver drugs specifically to tumor site. Polymeric conjugates based on N-(2-hydroxypropyl)methacrylamide are new generation polymeric anti-cancer drugs with enhanced cytostatic activity, but minimalized unwanted side effects.
Polymerní protirakovinná léčiva s pH- a enzymaticky závislou aktivací
Etrych, Tomáš ; Chytil, Petr ; Strohalm, Jiří ; Jelínková, Markéta ; Kovář, Marek ; Říhová, Blanka ; Ulbrich, Karel
Water-soluble synthetic polymers and their conjugates with antibodies, oligopeptides or saccharides proved a potential targetable drug delivery system. Recently, copolymers of N-(2-hydroxypropyl)methacrylamide (HPMA) have been developed in our laboratory as polymeric carriers of drugs.
