The Qx urea analog 6 acts on IKKβ and thereby inhibits the mTOR (mammalian target of rapamycin) and NF-κB pathways in pancreatic cancer and has shown good oral bioavailability along with in vivo efficacy, and being devoid of toxicities it becomes a viable cancer therapeutic [4c]. 1). ) and assessment of their therapeutic potential is still an active area of research in medicinal chemistry. Through the biological evaluation of a series of fluoro/trifluoromethyl quinoxalinones bearing various substituents (alkyl, haloalkyl, arylmethyl, and aryl groups) at C-3, the compounds 7 and 8 were found to have promising inhibitory activity against various strains of Candida [5a].

1) are used which offer ease of handling, high reactivity and selectivity, easy separation of the product, recyclability and reusability, and economic advantage. The major drawbacks with the heterogeneous catalyst are the higher amount required than the homogenous conditions and the blocking of the pores of the catalyst during the reaction progress. However, the reusability and the other benefits offered by the heterogeneous conditions outweigh these drawbacks. The PW12ZrO2 is a heteropolyacid (HPA) modified with zirconia and has acidic strength comparable to the protic acids.
