The present study was made to explore the metabolically active compounds from the macroalgae of the Andaman &amp;amp; Nicobar Islands. Methods and &lt;strong&gt;Material:&lt;/strong&gt; Different solvents such as methanol (MeOH), ethyl acetate (EtoAc), butanol (BuOH) and aqueous (H&lt;sub&gt;2&lt;/sub&gt;O) extracts of nine macroalgae were tested for antimicrobial, antibiofilm and cytotoxicity (brine shrimp larvae).&lt;strong&gt; Results:&lt;/strong&gt; Out of the 36 extracts 27 extracts showed antimicrobial activity against the human pathogens and 14 extracts revealed antibiofilm activities. The three EtoAc extracts of &lt;em&gt;Sargassum ilicifolium&lt;/em&gt;, MeOH extract of Sargassum sp. and MeOH extract of &lt;em&gt;Padina tetrastromatica&lt;/em&gt; showed inhibition against 8 pathogenic bacteria. Also, aqueous extract of &lt;em&gt;Padina tetrastromatica&lt;/em&gt; (71.82 %) and BuOH extract of &lt;em&gt;Dictyosphaeria cavernosa&lt;/em&gt; (71.58 %) exhibited higher antibiofilm nature. The highest cytotoxic effect was exhibited by species &lt;em&gt;Actinotrichia fragilis&lt;/em&gt; and all its four extracts significantly (P&amp;lt;0.01) inhibited the brine shrimp larvae, among this aqueous extract showed the lowest LC&lt;sub&gt;50&lt;/sub&gt; value, 31.7 &amp;mu;g/ml, followed by EtoAc extract, 89.33 &amp;mu;g/ml. &lt;strong&gt;Conclusion:&lt;/strong&gt; It was observed that different species have different kind of bioactive nature.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">815</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Sivadasan Deepa&lt;sup&gt;1*&lt;/sup&gt; Pitchiah Venkateshwaran&lt;sup&gt;1&lt;/sup&gt;, Nambali Valsalan Vinithkumar&lt;sup&gt;1&lt;/sup&gt;, Ramalingam Kirubagaran&lt;sup&gt;2&lt;/sup&gt; &lt;/strong&gt;&lt;/p&gt;
