Pochonin D
Pochonin D ((+)-Pochonin D) is an inhibitor of heat shock protein 90 (Hsp90) with antiviral and anti-inflammatory activities. Pochonin D inhibits Hsp90, affects the homeostasis, folding and assembly processes of viral proteins, and reduces the replication capacity of viruses. Pochonin D is a copper ion carrier that can induce cuproptosis in triple-negative breast cancer cells by targeting PRDX1. Pochonin D reduces the infiltration of inflammatory cells, decreases the secretion of inflammatory cytokines such as TNF-α and IL-1β, and alleviates inflammatory responses. Pochonin D is a promising candidate for research on human rhinovirus (HRV) infection and cancer.

Biological Activity
Pochonin D (0.4-10 μM; 2 days) potently inhibits the replication and cytopathic effect (CPE) of HRV1B in HeLa cells, and shows no cytotoxicity within the tested concentration range[2]
.
Pochonin D (0-40 μM; 1-7 days) significantly inhibits the proliferation and colony formation of TNBC cells (MDA-MB-231, 4T1, BT549, etc. cells), and is more sensitive to TNBC cells than other types of cancer cells[3].

Result:Reduced relative HRV1B NCR gene expression in lung tissue compared to vehicle-treated infected mice.
Decreased lung levels of CCL2, CXCL1, IL-1β, TNF-α, and IL-6 to near naïve control levels.
Significantly reduced BALF levels of CXCL1, IL-1β, TNF-α, and IL-6 compared to vehicle-treated infected mice.
Significantly lowered the number (1×104 cells) and percentage of myeloid-derived suppressor cells (MDSCs) in BALF compared to vehicle-treated infected mice.
Reduced lung edema, hemorrhage, and inflammatory cell infiltration, with lower histological scores compared to vehicle-treated infected mice.
Ameliorated tracheal airway cilia damage relative to vehicle-treated infected mice.
