A new multicomponent domino reaction for rapid and regioselective synthesis of highly functionalized benzo[h]pyrazolo[3,4-b]quinolines has been established. The reaction can be conducted by using readily available and inexpensive substrates under microwave irradiation within short periods of 10-26 min. Good to excellent chemical yields (61-91%) and complete regioselectivity have been achieved f...
Anticancer agents featuring hybrid molecules can improve effectiveness and diminish drug resistance. The current study aimed to introduce newly synthesized heterocyclic steroids of promising anticancer effects loaded in polyethylene glycol (PEG)•based nanoparticles form. Several heterocyclic steroids (1-9) were synthesized via multicomponent reactions (MCRs) and confirmed via the analytical and...
A simple and efficient procedure for the synthesis of 2-amino-3-cyanopyridines from aldehydes, ketones, malononitrile, and ammonium acetate via one-pot reaction is reported. Zinc zirconium phosphate (ZPZn) nanoparticles were used as a convenient and efficient catalyst for this multicomponent reaction (MCR) under solvent-free conditions, and fair to excellent yields were achieved. The catalyst w...

A mild and facile two-step access towards complex, polycyclic dibenzothiazepine derivatives via multicomponent reaction chemistry is demonstrated. The peculiar butterfly conformation observed studied.
Diffusion preserves the positivity of concentrations, therefore, multicomponent diffusion should be nonlinear if there exist non-diagonal terms. The vast variety of nonlinear multicomponent diffusion equations should be ordered and special tools are needed to provide the systematic construction of the nonlinear diffusion equations for multicomponent mixtures with significant interaction between...
Protein-protein interactions (PPIs) are broadly recognized as an emerging target class for a whole new era in drug discovery. They show significant differences to classical target classes and have been regarded as “undruggable” for a long time. Priaxon AG has developed a unique, proprietary technology platform for PPI drug discovery. PriaXplore employs novel computational and synthetic approach...
Colorectal cancer (CRC) is a major cause of cancer morbidity and mortality, and elucidation of its underlying genetics has advanced diagnostic screening, early detection, and treatment. Because CRC genomes are characterized by numerous non-random chromosomal structural alterations, we sought to delimit regions of recurrent amplifications and deletions in a collection of 42 primary specimens and...
