Understanding the formation of apremilast cocrystals [PDF]

open access: yesActa Crystallographica Section B Structural Science, Crystal Engineering and Materials, 2019
Apremilast (APR), an anti-psoriatic agent, easily forms isostructural cocrystals and solvates with aromatic entities, often disobeying at the same time Kitaigorodsky's rule as to the saturation of possible hydrogen-bonding sites. In this paper the reasons for this peculiar behavior are investigated, employing a joint experimental and theoretical ...

Energy Transfer in Nanodroplet‐Based Luminescent Solar Concentrators

open access: yesSmall, EarlyView.
We present novel luminescent solar concentrators (LSCs) featuring polymer composites with fluorescent dye‐doped oil nanodroplets. This liquid environment ensures high dye solubility and preserves fluorescence quantum yields, even at high local dye concentrations.

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods

open access: yesChirality, Volume 38, Issue 7, July 2026.
Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...

Phosphoryl Halogen and Hydrogen Bonding Controls the Solid‐State Structures of Aryl Halide‐Containing Phosphonates

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 17, 17 June 2026.
Intramolecular (RO)2PO→Halogen interaction versus intermolecular (RO)2PO···HOH hydrogen bonds. Although the O···I distance is shorter than the sum of the van der Waals radii of the atoms involved, there is no covalency involved in this interaction.

Structure‐Based Design, Synthesis, and Evaluation of Novel Ponatinib Derivatives With a Significantly Altered Selectivity Profile

open access: yesChemMedChem, Volume 21, Issue 11, 15 June 2026.
We developed new derivatives of the cancer drug ponatinib, significantly reducing and altering its spectrum of target kinases. Compound 5 retained the efficacy in inhibiting the colony formation of MDA‐MB‐231 cells and acted primarily on B‐Raf and Flt‐1 as its main targets in a kinase panel.

π‐Extended Chiral Molecular Triangular Prisms Exhibiting Boosted Circularly Polarized Luminescence Upon Self‐Assembly

open access: yesAggregate, Volume 7, Issue 6, June 2026.
A pair of π‐extended chiral triangular prisms based on pyromellitic diimide is synthesized from enantiopure macrocyclic precursors. They exhibit orange fluorescence and solvent‐dependent self‐assembly, enabling chiroptical inversion and amplification with |glum| values up to 1.15 × 10−2. Single‐crystal structures reveal solvent‐controlled conformations

Recent advances in organic broad‐spectrum photodetection materials and devices

open access: yesInfoMat, Volume 8, Issue 6, June 2026.
This review systematically outlines the evolution of organic photodetectors from fullerene‐based to advanced non‐fullerene acceptors, highlighting how molecular engineering (e.g., D–A, quinoidal, and A‐D‐A′‐D‐A architectures) extends spectral response into the short‐wave infrared region.
