One of the most popular strategies optimization drug properties in pharmaceutical industry appears to be a solid form changing into cocrystalline form. A number virtual screening approaches have been previously developed allow selection promising cocrystal formers (coformers) for an experimental follow-up. significant drawback those methods is related lack accounting crystallinity contribution formation. To address this issue, we propose study two coformer based on modern cloud-computing crystal structure prediction (CSP) technology at dispersion-corrected density functional theory (DFT-D) level. The CSP-based were first time validated challenging cases indomethacin and paracetamol cocrystallization, which provided poor predictions. calculations demonstrated dramatic improvement performance relative other methods. It that formation cocrystals dominant one and, therefore, should not ignored calculations. Our results encourage broad utilization proposed as only method directly accounts contribution.

Computational chemistry applications have become an integral part of the drug discovery workflow over past 35 years. However, computational modeling in support development has remained a relatively uncharted territory for significant both academic and industrial communities. This review considers workflows three key components preclinical clinical development, namely, process chemistry, analytical research as well product formulation development. An overview each step respective is presented. Additionally, context solid form design, special consideration given to modern physics-based virtual screening methods. covers rational approaches polymorph, coformer, counterion, solvent selection design.

In this study, the existing set of carbamazepine (CBZ) cocrystals was extended through successful combination drug with positional isomers acetamidobenzoic acid. The structural and energetic features CBZ 3- 4-acetamidobenzoic acids were elucidated via single-crystal X-ray diffraction followed by QTAIMC analysis. ability three fundamentally different virtual screening methods to predict correct cocrystallization outcome for assessed based on new experimental results obtained in study data available literature. It found that hydrogen bond propensity model performed worst distinguishing positive negative experiments 87 coformers, attaining an accuracy value lower than random guessing. method utilizes molecular electrostatic potential maps machine learning approach named CCGNet exhibited comparable terms prediction metrics, albeit latter resulted superior specificity overall while requiring no time-consuming DFT computations. addition, formation thermodynamic parameters newly evaluated using temperature dependences Gibbs energy. reactions between selected coformers be enthalpy-driven, entropy being statistically from zero. observed difference dissolution behavior aqueous media thought caused variations their stability.

Crystal structure prediction (CSP) is an invaluable tool in the pharmaceutical industry because it allows to predict all possible crystalline solid forms of small-molecule active ingredients. We have used a CSP-based cocrystal method rank ten potential coformers by energy cocrystallization reaction with antiviral drug candidate, MK-8876, and triol process intermediate, 2-ethynylglyclerol. For was performed retrospectively successfully predicted maleic acid as most likely be observed. The known form two different cocrystals 1,4-diazabicyclo[2.2.2]octane (DABCO), but larger landscape desired. screening triol-DABCO one, while triol-l-proline two. Computational finite-temperature corrections enabled determination relative crystallization propensities stoichiometries polymorphs free-energy landscape. obtained during subsequent targeted experiments found exhibit improved melting point deliquescence behavior over triol-free acid, which could considered alternative synthesis islatravir.

In this work, four novel pharmaceutical cocrystals of nitrofurantoin, an antibacterial drug, with isonicotinamide, picolinamide, 2-hydroxybenzamide, and 2-aminobenzamide have been obtained thoroughly characterized by various analytical techniques. The crystal structures the solid forms elucidated single-crystal X-ray diffraction, energy distribution intermolecular interactions has further quantified on basis QTAIMC analysis. Eight distinct supramolecular heterosynthons hydrogen bonding identified in studied crystals, their relative stability ranked terms total interaction energies. thermodynamics cocrystallization reactions systematically investigated using two independent experimental techniques, namely solution calorimetry phase solubility diagram, which allowed us to assess both enthalpic entropic contributions cocrystal formation driving force. pH-solubility behavior at different pH values eutectic concentrations components. Although all reported here were found be more soluble than parent advantage thermodynamic did not translate into enhanced dissolution performance due a rapid solution-mediated transformation aqueous media. addition, effect other pharmaceutically relevant properties including photostability membrane permeability, considered analyzed.
