Herein, we report the synthesis of nickel nanoparticles under mild conditions using porous alginate-g-poly(p-styrene sulfonamide-co-acrylamide) as a protecting/stabilizing agent and sodium borohydride as a reducing agent. The porous cross-linked polymeric support was preparedviacombining the use of sol-gel, nanocasting, and crosslinking techniques, in which thep-styrene sulfonamide monomer (PSSA) andN,N′-methylene-bis (acrylamide) (MBA) cross-linker underwent copolymerization on the surface of sodium alginate in the presence of a SiO2nanoparticle (NP) template (Alg-PSSA-co-ACA). The prepared catalyst (Alg-PSSA-co-ACA@Ni) showed high catalytic activity for the one-step synthesis of 1,3,4-oxadiazoles from the reaction of hydrazides and aryl iodides through isocyanide insertion/cyclization.

Soluble epoxide hydrolase (sEH) enzyme plays an important role in the metabolism of endogenous chemical mediators which are involved in the regulation of blood pressure and inflammation. Although the most reported potent sEH inhibitors are urea derivatives, these compounds have limited pharmacokinetic profile. In order to improve physicochemical properties, besides having favorable potency, amide non-urea derivatives with oxadiazole ring as a novel secondary pharmacophore against sEH enzyme were developed. Most of the novel compounds with appropriate physical properties, had comparable in vitro sEH inhibitory activity to 12-(3-Adamantan-1-yl-ureido)-dodecanoic acid (AUDA), a potent urea-based sEH inhibitor. The IC50value of the most potent compound (15c) was 0.43 nM.

A bis-amide antagonist of Smoothened, a seven-transmembrane receptor in the Hedgehog signaling pathway, was discovered via high throughput screening. In vitro and in vivo experiments demonstrated that the bis-amide was susceptible to N-acyl transferase mediated amide scission. Several bioisosteric replacements of the labile amide that maintained in vitro potency were identified and shown to be metabolically stable in vitro and in vivo.
