Abstract: Thiazolide compounds, such as nitazoxanide and/or tizoxanide, may be used against viruses belonging to the Picornaviridae family or the Paramyxoviridae family.

Abstract: Provided are methods of treating a disease or condition associated with an increased level of expression of a protein disulfide-isomerase A3 (PDIA3) by administering to a subject with an increased level of expression of PDIA3 a PDIA3-inhibiting effective amount of a thiazolide compound, such as nitazoxanide or tizoxanide. Also provided are methods of screening for therapeutic agents based on PDIA3 inhibition.

Abstract: A compound comprising a cyclopentanone, cyclopentenone, cyclohexanone or cyclohexenone group, wherein a first ring carbon atom carries an —SR substituent, R is a substituted or unsubstituted alkyl, alkenyl, alkynyl, aryl, aralkyl, aralkenyl, or aralkynyl group that, optionally, includes at least one heteroatom in its carbon skeleton, the remaining available ring carbon atoms are optionally substituted, and said compound either: —(a) is more soluble in water at a temperature of 20-40° C.; (b) is less lipophilic; and/or, (c) has a greater therapeutic index; or; (d) is less soluble in water at a temperature of 20-40° C.; (e) is more lipophilic; and/or, (f) has a greater therapeutic index; than an equivalent cyclohex-2-en-1-one or cyclopent-2-en-1-one derivative in which a hydrogen atom replaces said —SR group.

Abstract: The invention relates to 2-cyclopenten-1-one as an inducer of the heat shock protein HSP70 by activating the heat shock transcription factor HSF, and selectively inducing the transcription and translation of HSP70 in human cells. In particular, since a cytoprotective role of HSP70 during viral infection was previously shown, the invention refers to 2-cyclopenten-1-one and its pharmaceutically acceptable derivatives as inducers of HSP70 with antiviral activity. Treatment with 2-cyclopenten-1-one and its pharmaceutically acceptable derivatives causes a dose-dependent reduction of infectious virus yield during infection with vesicular stomatitis virus. The block of virus replication is due to inhibition of viral protein synthesis, associated with HSP70 synthesis.
