Impact of stabilizers on particle size and dispersion behavior in biorelevant media in solid nanocrystal formulations.

Nanocrystalline formulations typically contain stabilizing additives to minimize the risk of particle growth or agglomeration. This risk is particularly relevant when the nanosuspension is converted into a solid drug product as the original state of the nanosuspension should be restored upon redispersion of the drug product in vivo. In this work, the behavior of different nonionic and anionic surfactants in solid nanocrystalline formulations and their effects on redispersibility under biorelevant conditions were investigated.

Macrocyclization as a Strategy for Kinetic Solubility Improvement: A Comparative Analysis of Matched Molecular Pairs.

In recent years, rationally designed macrocycles have emerged as promising therapeutic modalities for challenging drug targets. Macrocycles can improve affinity, selectivity, and pharmacokinetic (PK) parameters, possibly via providing semirigid, preorganized scaffolds. Nevertheless, how macrocyclization affects PK-relevant properties is still poorly understood.

Toward Grid-Based Models for Molecular Association.

This paper presents a grid-based approach to model molecular association processes as an alternative to sampling-based Markov models. Our method discretizes the six-dimensional space of relative translation and orientation into grid cells. By discretizing the Fokker-Planck operator governing the system dynamics via the square-root approximation, we derive analytical expressions for the transition rate constants between grid cells.

Avirulence depletion assay: Combining R gene-mediated selection with bulk sequencing for rapid avirulence gene identification in wheat powdery mildew.

Wheat production is threatened by multiple fungal pathogens, such as the wheat powdery mildew fungus (Blumeria graminis f. sp. tritici, Bgt).
