Effect of molecular perturbation on cocrystal formation: theophylline and its 8‐halo analogues with flavonoids

Acta Crystallographica Section C, EarlyView.
The tendency for alkaloid–flavonoid cocrystal formation is found to be markedly different for theophylline (Tph) compared to its 8‐halo analogues. Through screening with 13 common flavonoids, Tph is found to form cocrystals with six flavonoids, whereas 8‐Cl‐Tph and 8‐Br‐Tph each form cocrystals with just two, myricetin and kaempferol.

The morphological affinities of the fossil cranium from Kabua, Kenya Affinités morphologiques du crâne fossile de Kabua (Kenya)

Journal of the Royal Anthropological Institute, EarlyView.
Our current understanding of the origins of Homo sapiens is limited, in part, by the fragmented fossil record from Late Pleistocene and early Holocene Africa. Here, we re‐examine the Kabua 1 cranium, an enigmatic and little‐studied Kenyan fossil discovered in the 1950s. We compare virtual reconstructions created previously by our team with a wide range

Evolutionary framework and tribal circumscription of Amaranthaceae sensu stricto based on a comprehensive phylogenomic analysis

Cladistics, EarlyView.
Abstract The evolutionary history of Amaranthaceae sensu stricto (s.s.) has been shaped by multiple whole‐genome duplications and rapid radiations, producing an ecologically diverse lineage whose internal relationships have long remained unresolved.

Landscape and Geography Determine Saproxylic Beetle Captures in Pheromone‐Baited Traps

Entomologia Experimentalis et Applicata, EarlyView.
Pheromone‐baited traps at 39 forest sites across southern Sweden captured 58 saproxylic beetle species, including seven Red‐listed taxa. The effect of surrounding forest cover on beetle abundance may depend on latitude and longitude: positive effects were strongest in warmer southern and eastern regions but weakened or reversed in colder northwestern ...

Human IDO2 exhibits unique binding affinities distinct to those of human IDO1

The FEBS Journal, EarlyView.
Although indoleamine 2,3‐dioxygenase 2 (IDO2) is highly homologous to IDO1, it displays markedly lower catalytic activity. We found that IDO2 binds L‐tryptophan (L‐Trp) in a flipped orientation stabilized by the IDO2‐specific residue His143. Replacement of His143 with the IDO1‐equivalent tyrosine restored an IDO1‐like binding mode and increased ...
