Antibiotic RK-682 is the calcium salt of one of a complex family of tetronic acids isolated from Streptomyces species. The formation of the salt is almost certainly an artefact of silica chromatography. RK-682 is the most extensively studied of the analogues, having been shown to inhibit protein tyrosine phosphatases and heparanase. Pharmacological studies with RK-682 demonstrated enhanced ATP-induced long-term potentiation using guinea-pig hippocampal slices. Investigation of the complex has also shown potent activity against HIV-1 protease.
