Abstract:
Background: Bimetallic catalysis plays a major role in boosting the catalytic performance
of monometallic counterparts due to the synergetic effect.
Materials andMethods: In the present study, we have exploited ZrCl4:Mg(ClO4)2 as an efficient
bimetallic catalyst for the synthesis of a few biologically relevant N-substituted decahydroacridine-
1,8-diones and xanthene-1,8-diones under solvent-free conditions.
Results: Among the compounds screened for anti-oxidant and anti-microbial activities, the acridine
derivatives with chloro and fluoro substitutions (compounds 4b, 4c, 4d, and 4j) have exhibited
potent activities when compared to other compounds. Among the xanthene derivatives
screened for anti-oxidant activity, compounds 5c, 5i, and 5j with chloro and nitro derivatives
exhibited potent antioxidant activity, and the rest all showed moderately potent activity.
Conclusion: Among the compounds screened for antibacterial activity, compound 5j with
chloro substitution showed potent activity, followed by compounds 5c, 5d, 5h, and 5i against
Gram +ve bacteria, and compounds 5h, 5f, and 5g with N,N-dimethyl, methoxy and hydroxy
substitutions have shown potent activity against Gram -ve bacteria.
