in vitro conversion of 5-carboxymethylidenehydantoin to orotic acid is not likely to occur in vivo since the two substances have antagonistic effects (2). A sulphur analogue of the above hydantoin has been prepared and shown not to undergo alkaline rearrangement to the corresponding metathiazine structure. The mechanism of orotic acid formation is discussed.
5-羧甲基乙内酰脲在体外转化为乳清酸在体内不太可能发生,因为这两种物质具有拮抗作用 (2)。已经制备了上述乙内酰脲的硫类似物,并且显示不会发生碱性重排成相应的间噻嗪结构。讨论了乳清酸形成的机制。
