Talk:Antimetabolite

Request for clarification

What does this sentence mean? "Anti-metabolites masquerade as a purine (azathioprine, mercaptopurine) or a pyrimidine, chemicals that become the building-blocks of DNA." It seems unlikely to me that antimetabolites would be defined as chemicals that masquerade as one of two classes of organic chemicals - surely they could potentially masquerade as anything. If this is true, then shouldn't it be part of the definition in the first line of the article? Alternately, if it isn't true, as I strongly suspect (but don't know), then this sentence would have to be changed to read something like "The Anti-metabolites that are used specifically in cancer treatment are ones that masquerade as a purine (azathioprine, mercaptopurine) or a pyrimidine, chemicals that become the building-blocks of DNA." Could somebody with more expert knowledge edit the article one way or the other? It would be appreciated. 203.26.125.101 (talk) 06:23, 28 July 2016 (UTC)
