Potential application of bisoprolol derivative compounds as antihypertensive drugs: synthesis and study.

Two bisoprolol derivatives, -acetyl bisoprolol and -formyl bisoprolol, belonging to the beta-blocker class of antihypertensive drugs, were synthesized using acetylation and formylation reactions. The yields of the reactions were determined to be 32.40% for -acetyl bisoprolol and 20.

Immobilization of Mucor miehei Lipase onto Macroporous Aminated Polyethersulfone Membrane for Enzymatic Reactions.

Immobilization of enzymes is one of the most promising methods in enzyme performance enhancement, including stability, recovery, and reusability. However, investigation of suitable solid support in enzyme immobilization is still a scientific challenge. Polyethersulfone (PES) and aminated PES (PES-NH2) were successfully synthesized as novel materials for immobilization.
