  • Patent number: 11884687
    Abstract: Tri-component multi-functional boronated complexes (B-complexes), featuring reversible covalent bonds, are described, which incorporate a drug; a water-soluble moiety (e.g. polyethylene glycol (PEG) chains, cyclodextrins); and a targeting unit. A B-complex core was assembled in one step, and proved to be stable in different biocompatible conditions, such as human plasma, though reversible for example in the presence of glutathione (GSH). This platform enabled the modular construction of the multifunctional conjugates exhibiting high selectivity towards, for example, folate-receptor-positive MDA-MB-231 cancer cells, having an IC50 in the low nanomolar range.

  • Patent number: 11752105
    Abstract: The present invention discloses a spray drying process characterized by continuous preparation and immediate spray drying of a solution comprising at least one active pharmaceutical ingredient and/or at least one excipient, and at least one solvent. The said active pharmaceutical ingredient(s) and solvent(s) are combined, alone or along with one or more excipients to form a first suspension. Said suspension is continuously fed to an intensifier pump that pushes said suspension through at least one micro-reaction chamber and/or at least one micro-channel where the suspension's solid(s) component(s) is(are) dissolved into said solvent(s) by means of high energy mixing I forced contact at micro, nano and molecular level to form a solution stream. The said solution stream is then immediately and continuously fed to the spray dryer through at least one atomization nozzle, drying said atomized stream to obtain solid particles and collecting said solid particles.
