encapsulated nanodroplet crystallisation (ENaCt) for small organic molecules: polymorph discovery

Crystallisation is of vital importance to the drug development pipeline of the pharmaceutical industry due to the existence of multiple crystal forms (e.g. cocrystals, solvates and polymorphs) of an active pharmaceutical ingredient (API). The physical properties of the crystal form of an API are important in manufacturing, API stability and can have significant impact on the rate of API uptake from the solid form (e.g. from a tablet), ultimately influencing both its formulation chemistry and the pharmacokinetics of the API.

Expanding High Throughput Nanolitre Solution-Phase Crystallisation for Polymorph Screening

Polymorphism is a solid-state phenomenon where a chemical species may adopt different conformational or packing arrangements, therefore allowing for the formation of more than one distinct crystal structure. Crystal polymorphs can exhibit varying physical and chemicalproperties. These properties such as solubility, hardness, colour, and melting point can all be important in the design of a compound in the crystal engineering and pharmaceutical industries. Typically, conducting polymorph screens requires a combination of classical crystallisation techniques which demand both large quantities of material and time to complete. Herein, we describe how encapsulated nanodroplet crystallisation (ENaCt) can be applied for low-quantity rapid polymorph screening using highly polymorphic 5-methyl-2-[(2-nitrophenyl)amino]-3-thiophenecarbonitrile (ROY) and nicotinamide as test compounds. ENaCt polymorph screening resulted in the growth, and analysis, of single crystals of a new polymorph of ROY ‘O22’. Crystal forms of both ROY and nicotinamide previously thought to be inaccessible to solution-phase crystallisation were also successfully grown, highlighting the capabilities of ENaCt for screening a diverse polymorphic landscape.
