</p><p><b>Geldanamycin</b> ist eine biologisch wirksame <a href="Chemische_Verbindung" title="Chemische Verbindung">chemische Verbindung</a>, genauer ein <a href="1%2C4-Benzochinon" title="1,4-Benzochinon">benzochinoides</a> <a href="Ansamycin" class="mw-redirect" title="Ansamycin">Ansamycin</a>, das vom <a href="Bakterium" class="mw-redirect" title="Bakterium">Bakterium</a> <i><a href="Streptomyces" title="Streptomyces">Streptomyces</a> hygroscopicus</i> produziert wird.
Es bindet spezifisch an das Hitzeschockprotein <a href="HSP90" class="mw-redirect" title="HSP90">HSP90</a> und ändert dessen Funktion. HSP90-Zielproteine spielen wichtige Rollen in der Regulation des <a href="Zellzyklus" title="Zellzyklus">Zellzyklus</a>, des Zellwachstums, des Zellüberlebens, der <a href="Apoptose" title="Apoptose">Apoptose</a>, <a href="Angiogenese" title="Angiogenese">Angiogenese</a> und <a href="Onkogenese" class="mw-redirect" title="Onkogenese">Onkogenese</a>. Durch Bindung von Geldanamycin an HSP90 werden Ziel-Proteine wie Tyrosinkinasen, Steroidrezeptoren, Transkriptionsfaktoren und Zellzyklus-regulierende Kinasen abgebaut. Es induziert die Inaktivierung, Destabilisierung und letztendlich den Abbau von HIF-1α.
</p><p>Geldanamycin induziert bevorzugt den Abbau von Proteinen, die in Krebszellen mutiert sind gegenüber den normalen Proteinen, wie z. B. bei v-src, bcr-abl und <a href="P53" title="P53">p53</a>. Dieser Effekt wird durch HSP90 vermittelt. Trotz seines hohen Antitumorpotentials, zeigt Geldanamycin einige Nachteile als Wirkstoffkandidat auf, insbesondere Hepatotoxizität, die Anlass gaben, Geldanamycin-<a href="Analogon_(Chemie)" title="Analogon (Chemie)">Analoga</a> zu entwickeln, vor allem solche, deren Position 17 <a href="Derivat_(Chemie)" title="Derivat (Chemie)">derivatisiert</a> ist:
