Prostaglandin A1 (PGA1) is a cyclopentenone prostaglandin containing chemically reactive α,β-unsaturated carbonyl. This cyclooxygenase 2 (COX-2) metabolic product aids in regulating the development and progression of Alzheimer′s disease (AD). In addition, PGA1 also regulates various biological processes via Michael addition. It exhibits antiviral activity against avian influenza A viruses (IAV) by inducing cytoprotective heat shock response in infected cells and by inhibiting nuclear factor-κB (NF-κB) activity.

Influenza A viruses (IAV) have the potential to cause devastating pandemics. In recent years, the emergence of new avian strains able to infect humans represents a serious threat to global human health. The increase in drug-resistant IAV strains underscores the
Cyclopentenone prostaglandins (cyPG) are reactive eicosanoids that may display anti-inflammatory and antiproliferative actions, possibly offering therapeutic potential. Here we report the identification of members of the aldo-keto reductase (AKR) family as selective targets of the cyPG prostaglandin A(1) (PGA(1)). AKR
The production of the antiaggregatory and vasodilatory prostacyclin (PGI2) in patients with gynaecological tumours was studied by assaying urinary 6-keto-prostaglandin F1a (= 6-keto-PGF1a), a hydration product of PGI2), by radioimmunoassay following high performance liquid chromatography (HPLC) in 59 patients with
Acute infection of mammalian cells with several types of RNA and DNA viruses often results in induction of heat-shock gene expression. The presence of hsp70 in intact virions, as well as the transient association of HSP with viral proteins and
Prostaglandin (PG) A1 is a metabolic product of cyclooxygenase 2 (COX-2) that is potentially involved in regulating the development and progression of Alzheimer's disease (AD). PGA1 is a cyclopentenone (cy) PG characterized by the presence of a chemically reactive α,β-unsaturated
