Structural Characterization and Rationalization of Formation, Stability, and Transformations of Benperidol Solvates

Experimental and theoretical characterization and studies of phase transitions and stability of the solvates obtained in solvate screening of the pharmaceutical compound benperidol were performed to rationalize and understand the solvate formation, stability, and phase transitions occurring during their desolvation. The solvate screening revealed that benperidol can form 11 solvates, including two sets of isostructural solvates. The analysis of the solvate crystal structures and molecular properties indicated that benperidol solvate formation is mainly driven by the complications during packing of benperidol molecules in an energetically efficient way in the absence of solvent molecules, as…

Benperidola solvātu struktūra, stabilitāte un fāžu pārejas

Darba ietvaros iegūtas vairākas jaunas benperidola polimorfās un solvatomorfās formas – metanola, acetonitrila, etilacetāta solvāti. No monokristālu rentgendifraktometrijas datiem atrasta metanola, etanola un acetonitrila solvāta kristāliskā struktūra. Pētīts solvātu desolvatācijas process un tā produkti, mainot desolvatācijas apstākļus, temperatūru, karsēšanas ātrumu, daļiņu izmēru un iegūšanas veidu. No termogravimetrijas datiem izotermiskā režīmā aprēķināti benperidola dihidrāta un etanola solvāta kinētiskie parametri – reakcijas ātruma konstantes un aktivācijas enerģijas – un analizēta procesu atbilstība biežāk sastopamajiem cietfāzu kinētikas modeļiem.
