One-photon ionization, leading to formation of hydrated electrons and radical cations, has been proposed as a possible mechanism of action of some sensitizers in photobiology. In this contribution, we have investigated this proposal for the compounds khellin and visnagin, used

Visnagin, which is found in Ammi visnaga, has biological activity as a vasodilator and reduces blood pressure by inhibiting calcium influx into the cell. The present study demonstrates the anti-inflammatory effect of visnagin on lipopolysaccharide (LPS)-stimulated BV-2 microglial cells. When

Vitiligo is an idiopathic leukoderma often with a progressive course causing destruction of melanocytes. The best methods for achieving cosmetically acceptable re-pigmentation of affected skin appear to be both local and systemic PUVA. They may, however, cause serious side effects
Salama Omar et al.
Photochemical & photobiological sciences : Official journal of the European Photochemistry Association and the European Society for Photobiology, 8(8), 1179-1186 (2009-07-30)
A theoretical investigation of the formation and spectroscopic properties of the furan and pyrone monoadducts between the photosensitizer khellin and DNA base thymine is reported. The thermal reaction pathways involve very high barriers, whereas the excited state surfaces display low
