Isbufylline can exert significant anti-inflammatory actions, in addition to its bronchodilator activity.

Pyridostigmine?is an?acetylcholinesterase inhibitor?that can treat myasthenia gravis by increasing acetylcholine at the postsynaptic motor endplate.

RGD-4C is a arginine-glycine-aspartic acid peptide (ACDCRGDCFC) with integrin binding activity. The Arg-Gly-Asp (RGD) sequence serves as the primary integrin recognition site in extracellular matrix proteins, and peptides containing this sequence can mimic the recognition specificity of the matrix proteins. RGD-4C is a αv-integrin ligand, can conjugate with bioactive molecule to exert antitumor effects in animal models.
