Doxorubicin hydrochloride (Adriamycin) 属于蒽环类抗生素,是人类 DNA 拓扑异构酶 I II 抑制剂 (IC50=0.8 2.67 μM)。Doxorubicin hydrochloride 具有细胞毒性和抗肿瘤活性。Doxorubicin hydrochloride 可降低 AMPK 及其下游靶蛋白乙酰辅酶 A 羧化酶的磷酸化,还可诱导凋亡和自噬。
Zoptarelin doxorubicin, also known as AEZS-108, is an LHRH agonist. Zoptarelin doxorubicin is a peptide agonist of the gonadotropin releasing hormone-1 receptor (GnRH-1R) that is conjugated to the anthracycline antibiotic doxorubicin with potential antineoplastic activity. Zoptarelin doxorubicin binds to GnRH-1Rs, which may be highly expressed on endometrial and ovarian tumor cell membrane surfaces, and is internalized. Once inside the cell, the doxorubicin moiety of this agent intercalates into DNA and inhibits the topoisomerase II activity, which may result in the inhibition of tumor cell DNA replication and tumor cell proliferation
DOX−NOP1 is a molecular hybrid covalently joining doxorubicin (DOX) and NOP1. DOX−NOP1 showed similar increased toxicity toward resistant cancer cells and, in addition, lower cardiotoxicity than DOX.
Aldoxorubicin has effective antitumor activities in various cancer cell lines and in murine tumor models. Aldoxorubicin is an albumin-binding prodrug of Doxorubicin (DNA topoisomerase II inhibitors).
