❓ Alzheimer's drugs mechanism of action?

Donepezil, rivastigmine and galantamine all prevent an enzyme called acetylcholinesterase from breaking down acetylcholine. This means there is a higher concentration of acetylcholine in the brain, which leads to better communication between nerve cells. This may ease some symptoms of Alzheimer's disease for a while.

❓ Anticholinergic drugs mechanism of action?

Anticholinergic drugs block the action of a neurotransmitter called acetylcholine. This inhibits nerve impulses responsible for involuntary muscle movements and various bodily functions. These drugs can treat a variety of conditions, from overactive bladder to chronic obstructive pulmonary disorder.

❓ Cancer drugs mechanism of action?

Anticancer drugs are traditionally classified either by their mechanism of action or by their origins. Alkylating agents are reactive to DNA and cellular proteins and the primary mode of action is mostly through cross-linking of DNA strands, inhibiting replication of DNA and transcription of RNA.

What are the mechanism of action of antibiotics?

The main target of action is bacterial ribosome; to enter, there it must pass through cytoplasmic membrane requiring energy dependent active bacterial transport mechanism, which requires oxygen and an active proton motive force. For these reasons, AG work in aerobic conditions and have poor activity against anaerobic bacteria.

What is the mechanism of action for macrolide antibiotics?

In this review we summarize the current knowledge, as well as unsolved questions, regarding the principles of macrolide binding to the large ribosomal subunit and the mechanism of drug action. Two mechanisms of macrolide resistance, inducible expression of Erm methyltransferase and peptide-mediated resistance, appear to depend on specific interactions between the ribosome-bound macrolide molecule and the nascent peptide.
