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

Chirality, 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 ...

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

ChemMedChem, 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.

A Review on Pharmaceutical Cocrystals

International Journal of Pharmaceutical Research and Applications
Pharmaceutical cocrystals are crystalline materials composed of two or more different molecules, at least one being an active pharmaceutical ingredient (API), in a fixed stoichiometric ratio, held together by non-covalent interactions.Cocrystal can be prepared by cocrystallization method.

Intrinsically dominant conformational diversity in PDZ1 within the tandem PDZ1–PDZ2 of human syntenin‐1 underlied by crystal structures

Protein Science, Volume 35, Issue 6, June 2026.
Abstract The intrinsic dynamic asymmetry between homologous PDZ domains in multidomain scaffold proteins offers insight into how they achieve multivalent partner recognition. Through a systematic x‐ray crystallographic analysis of tandem PDZ1–PDZ2 domains in human syntenin‐1 (SDCBP/MDA‐9), we solved nine high‐resolution structures and uncovered ...

Understanding Water Activity in Deep Eutectic Solvents: Experimental Screening, Thermodynamic Modeling, and QSAR Predictions

ChemistrySelect, Volume 11, Issue 21, 4 June 2026.
Water activity (aw) was measured in eight DESs (10–90 wt% water). Strong DES–water interactions persist to ∼50 wt%, after which structure collapses toward aqueous‐like behavior. Redlich–Kister, Wilson, and COSMO‐RS models showed limited performance, whereas QSAR modeling using COSMOtherm‐derived σ‐profile descriptors significantly improved aw ...

Structure and intermolecular interactions of the rare amide–pyridine synthon: a cocrystal of nicotinamide and 2‐chloro‐3‐hydroxypyridine

Acta Crystallographica Section C, Volume 82, Issue 6, Page 267-276, June 2026.
Considering its low occurrence in the Cambridge Structural Database, is the amide–pyridyl synthon easy to form, and what structural factors affects its interaction energy and its subsequent formation?Nicotinamide (Nico) and derivatives of pyridine are important materials in both the pharmaceutical and agrochemical industries.

Dissolution Advantage of Nitazoxanide Cocrystals in the Presence of Cellulosic Polymers

Pharmaceutics, 2019
The effect of hydroxypropyl methylcellulose (HPMC) and methylcellulose (Methocel® 60 HG) on the dissolution behavior of two cocrystals derived from nitazoxanide (NTZ), viz., nitazoxanide-glutaric acid (NTZ-GLU, 1:1) and nitazoxanide-succinic acid ...

Pharmaceutical Cocrystals: An Overview

Asian Journal of Pharmaceutical Research and Development
Poor aqueous solubility and low oral bioavailability of an active pharmaceutical ingredient are the major constraints during the development of new product. Various approaches have been used for enhancement of solubility of poorly aqueous soluble drugs, but success of these approaches depends on physical and chemical nature of molecules being developed.
