Good substrate gone bad! BN/CC isosterism of ethylbenzene leads to N-ethyl-1,2-azaborine and B-ethyl-1,2-azaborine. In contrast to ethylbenzene, which is the substrate for ethylbenzene dehydrogenase (EbDH), N-ethyl-1,2-azaborine (see scheme; Fc=Ferricenium tetrafluoroborate) and B-ethyl-1,2-azaborine are strong inhibitors of EbDH. Thus, the changes provided by BN/CC isosterism can lead to new biochemical reactivity.

Grouping behaviours (e.g. schooling, shoaling and swarming) are commonly explicated through adaptive hypotheses such as protection against predation, access to mates or improved foraging. However, the hypothesis that aggregation can result from manipulation by parasites to increase their transmission has never been demonstrated. We investigated this hypothesis using natural populations ...
