18. INTERACTION OF CHALCONES WITH CT-DNA BY SPECTROPHOTOMETRIC ANALYSIS AND THEORETICALSIMULATIONS
Chalcones are open chain molecules precursors of flavonoids and isoflavonoids, found spread in edible plants. Because they are easily accessible trough Claisen Shmidt condensation, a great variety of derivatives are available. They have also shown potential in pharmacological and biological applications. It is known that chalcone derivatives display a role i

19. Citronellal-induced disruption of membrane homeostasis in Candida albicans and attenuation of its virulence attributes
Abstract: INTRODUCTION There is an increasing burden of multidrug resistance. As a result, deciphering the mechanisms of action of natural compounds with antifungal activity has gained considerable prominence. We aimed to elucidate the probable mechanism of action of citronellal, a monoterpenoid found in the essential oil extracted from Cymbopogon plants,
