RESUMO
Methanolic extracts of 31 botanically identified species of marine flora, collected from Gujarat Coast, have been screened for a wide range of biological activities. Of these, 3 extracts showed anti-implantation, 2 had antiviral, 2 showed hypotensive, 1 had anti-inflammatory while 12 extracts showed diuretic activities. The antiviral activity; against EMCV, was confirmed in one alga. The active principles and results of these studies are reported.

The 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR) inhibitory activity of 7-(aryl/biphenyl)-6-heptenoic acids was quantitatively analysed using hydrophobicity, van der Waals volume and electronic parameters. The activity was primarily a function of hydrophobicity, and was well correlated with the hydrophobicity of ortho and meta substituents on the aryl/biphenyl moiety. The electronic properties of para substituents on the aryl/biphenyl ring influenced the inhibition. Our equations predict that substituents with positive polar and sigma and negative resonance constants might lead to better inhibition.
