HDN-1 is a naturally occurring fungal
epipolythiodioxopiperazine / epipolythiopiperazine-2,5-dione
(ETP) isolated from the Antarctic fungus
Oidiodendron truncatum GW3-13. HDN-1 has demonstrated preclinical
anticancer activity and acts as a direct Hsp90 inhibitor,
binding the C-terminal region of Hsp90α. Hsp90 inhibition by HDN-1 promotes
degradation of multiple oncogenic client proteins, enhances downregulation of
wild-type and mutant EGFR and suppresses tumour-cell proliferation. HDN-1 has
also induced differentiation followed by apoptosis in selected promyelocytic
leukemia cell lines. Its mechanism overlaps with that of the structurally
related ETP chaetocin, which also inhibits Hsp90, but HDN-1 and chaetocin are
chemically distinct compounds and should be maintained as separate products.
HDN-1 should be classified as an experimental natural fungal metabolite
/ epipolythiodioxopiperazine / Hsp90 inhibitor, with current anticancer
evidence predominantly preclinical. |

| Also called CCND1 Gatekeeper of Cell-Cycle Commitment The main function of cyclin D1 is to maintain cell cycle and to promote cell proliferation. Cyclin D1 is a key regulatory protein involved in the cell cycle, particularly in the transition from the G1 phase to the S phase. It is part of the cyclin-dependent kinase (CDK) complex, where it binds to CDK4 or CDK6 to promote cell cycle progression. Cyclin D1 is crucial for the regulation of the cell cycle. Overexpression or dysregulation of cyclin D1 can lead to uncontrolled cell proliferation, a hallmark of cancer. Cyclin D1 is often found to be overexpressed in various cancers. Cyclin D1 can interact with tumor suppressor proteins, such as retinoblastoma (Rb). When cyclin D1 is overexpressed, it can lead to the phosphorylation and inactivation of Rb, releasing E2F transcription factors that promote the expression of genes required for DNA synthesis and cell cycle progression. Cyclin D1 is influenced by various signaling pathways, including the PI3K/Akt and MAPK pathways, which are often activated in cancer. In some cancers, high levels of cyclin D1 expression have been associated with poor prognosis, making it a potential biomarker for cancer progression and treatment response. |
