An invention that adduces cogent evidence to establish that oxygenated dibenzo-α-pyrones (DBPs and their conjugates), the major bioactives of shilajit (Ayurvedic vitalizer), have their origin, at least partly, in EPA and DHA. Earlier research has shown that, in mammals, C-20 PUFAs are metabolized by oxygenases and other enzymes to produce short-lived prostaglandins, leukotrienes and thromboxanes that bind to specific G-protein-coupled receptors and signal cellular responses, e.g., inflammation, vasodilation, blood pressure, pain etc. But never before it was suggested/shown that C_20:5n-3 (and C_{22:6 n-3}) PUFAs, e.g., EPA (and DHA), are transformed into stable aromatic metabolites, DBPs, which elicit a large array of bioactivities in the producer organisms and also control the synthesis and metabolism of arachidonate-derived prostaglandins. The major beneficial effects attributed to EPA and DHA are now found to be largely contributed by DBPs and their aminoacyl conjugates and the dibenzo-α-pyrone-chromoproteins (DCPs). Because of the highly unstable nature of EPA and DHA, when administered, they are metabolized into a large array of uncontrolled products, several of which are systemically undesirable. By contrast, DBPs, because of their stability, perform the biological response modifier (BRM) functions in a directed and sustained way. Many of the biological effects of DBPs described in this invention, were earlier attributed to EPA and DHA,—the precursors of DBPs.

The present invention provides novel mechanisms that regulate the production of anti-inflammatory and pro-inflammatory mediators generated by 5-lipoxygenase. In this regard, the present invention establishes that phosphorylation of 5-Lipoxygenase by protein kinase A, has a crucial role in determining the end products of 5-Lipoxygenase. With translocation to the nucleus, potent proinflammatory leukotrienes are produced, whereas following phosphorylation by protein kinase A, anti-inflammatory mediators are produced. The present invention also discloses compounds that regulate these pro- and anti-inflammatory mediators.
