Pyrvinium is an anthelmintic effective for pinworms. Several forms of pyrvinium have been prepared with variable counter anions, such as [1 ] halides, tosylate, triflate and pamoate. [2 ] [3 ]
Pyrvinium salts can also inhibit the growth of cancer cells.
More specifically, the pamoate salt has been shown to have preferential toxicity for various cancer cell lines during glucose starvation. [4 ] [5 ]
Synthesis [ edit ]
One synthetic method is based on
Skraup synthesis and Paal-Knorr synthesis. More recently, an alternative convergent, synthetic strategy to pyrvinium triflate salts through [4 ] Friedländer synthesis was reported. [3 ]
