Lipoxygenase inhibitors are used as cytoprotective active ingredient in producing cytoprotective pharmaceutical compositions. Corresponding cytoprotective pharmaceutical compositions are prepared by incorporating into a pharmaceutical composition a lipoxygenase inhibitor in a cytoprotective active amount. The prepared cytoprotective therapeutic composition may be used to treat or prevent disease states such as erosive gastritis, erosive esophagitis, inflammatory bowel disease, and induced hemorrhagic gastric erosions such as those caused by indomethacin or ethanol. The lipoxygenase inhibitors induce cytoprotection via an unspecified mechanism.

The biocatalytic synthesis of phenothiazones and related compounds has been achieved in an aqueous system under mild conditions facilitated by laccase oxidation. It was found that by coupling 2-aminothiophenol directly with 1,4-quinones, the product yields could be significantly increased compared to generating the 1,4-quinones in situ from the corresponding hydroquinones via laccase oxidation. However
