Small-molecule compounds with high activity/strong selectivity need to possess druggability before they may eventually become commercially marketed drugs. Among these pharmaceutical properties, crystal structure has become one of the indispensable part in the research process. The medicinal crystal structure is essential in the development of drugs. Alfa Chemistry has developed a diversity of calculation tools to assist in predicting and discovering the crystal structure. We perform accurate crystal structure prediction to predict the possible crystal structure through calculation based on a given two-dimensional structure.
Polymorphism is a phenomenon that the same substance has two or more spatial arrangements and unit cell parameters, which can form multiple crystal structures. It has been found that different crystal structure of the same drug may have significant differences in appearance, solubility, melting point, dissolution, and bioavailability, which affects the stability, bioavailability and efficacy of the drug. Crystal structure prediction of small molecule drugs therefore plays a crucial role in improving the bioactivity in the new drugs.
