Therefore, it would be favorable to find promising agents with antioxidant and antimicrobial activity combined in one molecule. &lt;strong&gt;Key findings:&lt;/strong&gt; Pyrimido[4,5-b] quinolines are biologically active compounds that are known to rely primarily on the functional group’s existence and location. Quinolinbenzo-[ 1,3]oxazin-4-one &lt;strong&gt;(3)&lt;/strong&gt; was prepared and played as electrophilic interface/mediator for the synthesis of many compounds, such as pyrimido[4,5-b]quinoline, quinoline-carboxamide and oxoquinazolin-acetamide by reacting with nucleophilic reagent. &lt;strong&gt;Summary: &lt;/strong&gt;Results revealed that pyrimido[4,5-b] quinoline derivatives (&lt;strong&gt;17b, 9d&lt;/strong&gt; and &lt;strong&gt;9c&lt;/strong&gt;) are the most potent compounds that displayed significant antimicrobial activity along with compounds 17a, 29b, 5, 19, 23b, and 25b that appeared to be more promising as antioxidant agents than ascorbic acid.&lt;/p&gt;

It is extensively used in Ayurveda, Unani and Siddha medicine as a home remedy for various diseases. &lt;strong&gt;Aim:&lt;/strong&gt; The present study is to compare the antimicrobial activity of the ethanolic extracts from rhizome and leaf of &lt;strong&gt;Curcuma longa&lt;/strong&gt; Linn. &lt;strong&gt;Method:&lt;/strong&gt; &lt;em&gt;In vitro&lt;/em&gt; disc diffusion method and serial dilution method has been used to determine the antimicrobial potency against various bacterial pathogens such as &lt;em&gt;Klebsiella pneumoniae, Pseudomonas aeruginosa&lt;/em&gt;, &lt;em&gt;Staphylococcus aureus&lt;/em&gt; and &lt;em&gt;Bacillus subtilis&lt;/em&gt; by comparing the zone of inhibition shown by both the test extracts at different concentration (25 mg/ml, 50 mg/ml, 100 mg/ml, 150 mg/ml, 200 mg/ml, 250 mg/ml, 300 mg/ml) and there MIC value has been evaluated. Ethanol and Ampicillin were used as negative and positive control for the study. &lt;strong&gt;Result:&lt;/strong&gt; The leaf and rhizome extract showed maximum zone of inhibition at 300 mg/ml concentration, which was about 7.6 mm and 8 mm on the bacterial strain &lt;em&gt;Pseudomonas aeruginosa&lt;/em&gt; and least effectiveness for other bacterial strain such as &lt;em&gt;Staphylococcus aureus&lt;/em&gt; and &lt;em&gt;Bacillus subtilis&lt;/em&gt;. The recorded MIC value was at 6.25 mg/ml which showed 3.991% inhibition for rhizome extract and 3.129% inhibition for leaf extract. &lt;strong&gt;Conclusion:&lt;/strong&gt; The rhizome extract was found to be more potent antimicrobial agent than the leaf extract and can be used in future studies.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">208</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Nikhil Singh*, Sangeeta Gupta, Vaibhav Rathore &lt;/strong&gt;&lt;/p&gt;
