In our work, the morpholine has included the addition of inorganic anions like nitrate and nitrite for forming morpholinium based Ionic Liquid. Their chemical properties, biochemical properties, and physio-chemical properties are evaluated using computational chemistry through the Density Functional Theory (DFT). The biological properties have been shown that biological activity in the designed ionic liquid for uses in new drug discovery. From QSAR study, the value of the LogP is 0.713 and 1.7 which indicates hydrophobic nature and PIC50 is -2.14 and -3.96 respectively. The nitrate and nitrite comparison have been highlighted through this work. From QSAR and PIC50, it is seen that due to the nitrate addition with morpholine is more biological activity than nitrite. On the other hand, the toxicity of nitrate is less than nitrite. %U http://www.ajchem-a.com/article_87152_c3a720145636728af53625b5b0777cf1.pdf
