ABSTRACT
The bioactive compounds of Gracilaria edulis were determined by using Gas Chromatography Mass spectroscopy. The drug compounds were screened for analyzing the inhibition potential against the virulent bacterial enzyme. In this research, the protein responsible for bacterial infection was docked against the drug compounds of Gracilaria edulis. The data of the virulent enzymes are studied and retrieved from PDB. The bioactive compounds were screened by Lipinski rule of five and ADMET properties. Using Autodock 4.2.6 the molecular docking analysis were done against virulent enzymes and was visualized by discovery studio 3.1. The bioactive compound eugenol with binding energy -4.42 Kcal/mol followed by 2 Heptene, 2,4,4,6 tetramethyl -3.89 Kcal/mol and 1, 2-Propanediol 2.77 Kcal/mol. The hydrogen and vanderwaals interaction of amino acids were studied. This research work mainly focuses on targeting the virulent enzymes that can reduce clinical costs by designing novel drug.
ABSTRACT
Studies on natural and anthropogenic radioactivity assume greater importance in the context of human health and development. Hence two species of seaweeds viz: Gracilaria edulis and Ulva lactuca, from three high background radiation areas (Arockiapuram, Kadiapattinam and Kurumpanai) on the southwest coast of Tamil Nadu, and Mandapam as low background radiation area of the southeast coast of Tamil Nadu were studied for variations in activity concentration of 228 Ra, 40 K, 238 U and 228 Th. Among these radionuclides, 40K recorded significant inter-species variation while 238 U and 228 Th showed significant association. The overall mean concentration of radionuclides was found high in G.edulis (5.31, 57.49, 36.05, 356.55 Bq kg-1 for 228 Ra, 40K, 238U, 228 Th respectively), while the mean concentrations for U.lactuca were 4.88, 42.35, 34.40, 347.70 Bqkg-1 for 228 Ra, 40K, 238U, 228 Th respectively. The mean concentration of radionuclides was uniformly found low during northeast monsoon season in both the seaweed species.
