In the present study, a new series of -Aminophosphonates bearing 6-amino-1,3-dimethyluracil was synthesized in good to excellent yields (78-95%) by one-pot, three-component reaction of 6-amino-1,3-dimethyluracil, aromatic aldehydes and diethylphosphite Kabachnik-Fields reaction by using an eco-friendly Eaton's reagent. All the compounds were screened for antioxidant studies by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and hydrogen peroxide (HO) methods. Among the synthesized bioactive molecules, , , , and exhibited promising antioxidant activity compared with the standard drug Ascorbic acid. Furthermore, in order to support the biological results of the compounds, molecular docking studies were performed against Aromatase enzyme for four compounds which revealed that the compounds , , , and have significant binding modes, with docking scores of -8.6, -8.4, -8.1 and -8.1 respectively and the compound specifically has equal dock score of -8.0 when compared with the standard drug Exemestane.

Discoidin domain receptors (DDR) are categorized under tyrosine kinase receptors (RTKs) and play a crucial role in various etiological conditions such as cancer, fibrosis, atherosclerosis, osteoarthritis, and inflammatory diseases. The structural domain rearrangement of DDR1 and DDR2 involved six domains of interest namely N-terminal DS, DS-like, intracellular juxtamembrane, transmembrane juxtamembrane, extracellular juxtamembrane intracellular kinase domain, and the tail portion contains small C-tail linkage. DDR has not been explored to a wide extent to be declared as a prime target for any particular pathological condition.

Enzymes are the cornerstone of biocatalysis, biosynthesis and synthetic biology. However, their applicability is often limited by low substrate selectivity. A prime example is the bifunctional linalool/nerolidol synthase (LNS) that can use both geranyl diphosphate (GPP) and farnesyl diphosphate (FPP) to produce linalool and nerolidol, respectively.

The suppression of tyrosinase (TYR), a key enzyme in melanogenesis, has been suggested as an effective strategy for preventing melanin accumulation. We previously discovered the novel chrysin derivative hydroxyethyl chrysin (HE-chrysin) through an irradiation technique, which exerted higher anti-inflammatory and anti-cancer activities than original chrysin. In the present study, we explored whether HE-chrysin has antioxidant and anti-melanogenic capacity using B16F10 murine melanoma cells and molecular docking.
