A new series of fatty acid amides viz. N-(4-methoxybenzyl)undec-10-enamide (5), (9Z, 12R)-12-Hydroxy-N-(4-methoxybenzyl)octadec-9-enamide (6) and N-(4-methoxy benzyl)oleamide (7) were synthesized by using a suitable synthetic route involving DCC and DMAP as catalysts. The synthesized compounds were characterized through FTIR, NMR spectroscopy, and mass spectrometry. DNA binding studies through spectroscopy and molecular docking were performed to evaluate the binding mechanism of molecules (5-7) with (ctDNA). The inhibition zone with reference to standards, Minimum Inhibitory Concentration (MIC) and Minimum Killing Concentration (MKC) values were determined to study the in vitro antimicrobial activity for tested compounds. Among all the tested compounds, the compound 6 containing hydroxy group at the fatty acid chain showed most powerful antifungal as well as antibacterial activity., Competing Interests: The authors declare no conflict of interest., (© 2021 Published by Elsevier Ltd.)

Seed extracts of Nymphia alba Linn. and Lupinus polyphyllus Lindl. were analyzed for fatty acid composition, functional group analysis and antioxidant activity. The petroleum ether extract of seeds were found dominant in unsaturated fatty acids with oleic acid (39.9%) and linoleic acid (29.6%) in L. polyphyllus and linoleic (37.5%) and oleic acid (10.9%) in N. alba. All the defatted seed extracts of N. alba and L. polyphyllus found to have powerful DPPH, ABTS, H 2 O 2 and NBT antioxidant radical scavenging activity with reference to butylated hydroxy toluene (BHT). The defatted seed extracts were further analyzed with functional group analysis through FTIR found to contain numerous functional groups which may be responsible for their antioxidant activity.
