HDN-1, epipolythiodioxopiperazine / epipolythiopiperazine-2,5-dione: Click to Expand ⟱
Features:

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.
HDN-1 is an analogue of chaetocin, which is a fungal mycotoxin with histone methyltransferase SUV39H1 inhibitory activity

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.
