Bioisosteric replacement of central 1,2,4-oxadiazole ring of high affinity CB2 ligands by regioisomeric 1,3,4-oxadiazole ring [PDF]
It has been reported that bioisosteric replacement of an 1,2,4-oxadiazole ring by an 1,3,4-oxadiazole ring leads to higher polarity, reduced metabolic degradation by human liver microsomes and reduced interaction with hERG channels.

Benzamides boost crop resilience by inhibiting poly(ADP‐ribose) polymerase (PARP) to enhance stress tolerance and, through their antimicrobial, herbicidal, and insecticidal derivatives, they offer broad protection for sustainable crop improvement. Abstract Benzamides have emerged as potent stress inhibitors and growth promoters in plant biotechnology ...

A broadly applicable synthetic platform based on a DOS/LOS‐like strategy is implemented for the case of sp3‐enriched isoxazole/isoxazoline building blocks. The method is based on a [3+2] cycloaddition of nitroalkanes and various alkenes or alkynes. The utility of the proposed approach is illustrated by the discovery of JAK2‐selective inhibitors.
