Benzene is an important organic compound with the chemical formula C6H6, and its molecule consists of a ring of 6 carbon atoms, each with 1 hydrogen atom. Benzene is a sweet, flammable, colorless and transparent liquid with carcinogenic toxicity at room temperature, and has a strong aromatic odor. It is insoluble in water, easily soluble in organic solvents, and can also be used as an organic solvent itself. The ring system of benzene is called benzene ring, and the structure after removing one hydrogen atom from the benzene ring is called phenyl. Benzene is one of the most important basic organic chemical raw materials. Many important chemical intermediates can be derived from benzene through substitution reaction, addition reaction and benzene ring cleavage reaction.
In positive interim analysis results from the phase 3 trial ECHO, acalabrutinib (Calquence; AstraZeneca) in combination with standard of care chemoimmunotherapy—bendamustine and rituximab—demonstrated both statistically significant and clinically meaningful improvement in progression-free survival (PFS) in adult patients with previously untreated mantle cell lymphoma (MCL) compared with standard of care alone. Acalabrutinib is a next-generation, selective inhibitor of Bruton tyrosine kinase (BTK) that binds covalently to BTK to hinder its activity. BTK signaling results in the activation of pathways that are necessary for B-cell proliferation, trafficking, chemotaxis, an adhesion within B cells.
