H3B-8800

According to the NCI website the splicing inhibitor H3B-8800 is an orally bioavailable inhibitor of the splicing factor 3B subunit 1 (SF3B1), with potential antineoplastic activity. Upon administration, H3B-8800 binds to and blocks the activity of SF3B1, a core spliceosome protein that is mutated in various cancer cells. This modulates RNA splicing by preventing aberrant mRNA splicing by the spliceosome, blocks RNA mis-splicing, enhances proper RNA splicing and prevents the expression of certain tumor-associated genes. This leads to an induction of apoptosis and prevents tumor cell proliferation. In many cancer cells, core spliceosome proteins, including SF3B1, U2 small nuclear ribonucleoprotein auxiliary factor 1 (U2AF1), serine/arginine-rich splicing factor 2 (SRSF2) and U2 small nuclear ribonucleoprotein auxiliary factor subunit-related protein 2 (ZRSR2), are mutated and aberrantly activated leading to a dysregulation of mRNA splicing.

Hydroxyurea/Hydroxycarbamid - LITALIR®

Der Antimetabolit Hydroxyurea/Hydroxycarbamid - Litalir® ist ein monohydroxyl-substituierter Harnstoff (Hydroxycarbamat). Hydroxyurea hemmt selektiv die Ribonucleosid-Diphosphat-Reduktase, ein Enzym, das für die Umwandlung von Ribonukleosid Diphosphat zu Desoxyribonukleosid Diphosphat erforderlich ist, wodurch die Zellen am Verlassen der G1/S-Phase des Zellzyklus gehindert werden. Dieses Mittel weist auch radiosensibilisierende Aktivitäten auf, indem es Zellen in der strahlungsempfindlichen G1 Phase verharren lässt und die DNA-Reparatur stört.

Indikationen/Anwendungsmöglichkeiten gemäss Compendium®:

  • Chronisch-myeloische Leukämie und andere myeloproliferative Syndrome wie essentielle Thrombozythämie, Myelofibrose und Polycythaemia vera mit starker Thrombozytose.
