A series of olanzapine (OLN) dicarboxylic acid salts including earlier reports on olanzapinium malonate (1:1) and maleate (1:1 and 1:2) were prepared mechanochemically using liquid assisted grinding (LAG) in order to study their hydration stability. Powder Xray diffraction was used as a characterization tool during the investigation. On the basis of the single crystal structures of respective OLN salts, a negative correlation between the dicarboxylic acid chain length and the hydration stability of the corresponding OLN salt was found. Our observations suggest that the overall crystal packing, beyond the stronger hydrogen bond synthon () plays an important role in designing OLN salts with better hydration stability. In addition, melting point analysis showed that OLN dicarboxylic acid salts follow melting point alteration behavior similar to the pure diacids.
The present study aims for phytochemical investigation and mechanistic study of the antihyperglycemic effect of the Wendlandia glabrata DC, a lesser explored traditional herb used by the indigenous communities of...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
