4-Thio-uridylate (UD29) interferes with the function of protein -SH and inhibits HIV replication in vitro.
Journal Title: Pharmacological Reports - Year 2009, Vol 61, Issue 2
Abstract
In this short communication, it is shown that 4-thio-uridylate (s(4)UMP, designated as UD29) inhibits glyceraldehyde 3-phosphate dehydrogenase (GAPDH), suggesting that the enol-form of the thiolated nucleotide may interfere with the function of the essential -SH group in the active center of the enzyme. Since HIV entry requires thiol/disulfide exchange processes, this activity prompted us to study the anti-HIV activity of the nucleotide. Indeed, UD29 inhibited the replication of HIV-1(IIIB) in the MT-4 cell line and HIV-1(Ada-M) in peripheral blood mononuclear cells (PBMC). Furthermore, UD29 was not toxic in PBMCs in vitro or in mice when the compound was administered intravenously.

Mechanisms of platelet-activating factor (PAF)-mediated responses in the lung.
Platelet-activating factor (PAF) is a potent lipid mediator that has been implicated in asthma, sepsis, acute lung injury and ischemia/reperfusion injury. Its actions in the lungs include vasoconstriction, bronchoconstri...
Benzodiazepine/GABA(A) receptors are involved in magnesium-induced anxiolytic-like behavior in mice.
Behavioral studies have suggested an involvement of the glutamate pathway in the mechanism of action of anxiolytic drugs, including the NMDA receptor complex. It was shown that magnesium, an NMDA receptor inhibitor, exhi...
