Abstract
This invention provides a novel compound expressed by the following formula (1): ##STR1## [wherein R.sup.1 denotes a hydrogen atom or CH.sub.3 CO--, R.sup.2 denotes --COOR.sup.4 (R.sup.4 denotes Na or a methyl group) or ##STR2## (R.sup.5 denotes a hydrogen atom, --COC.sub.6 H.sub.5 or --Si(C.sub.6 H.sub.5).sub.2 C(CH.sub.3).sub.3 and R.sup.3 denotes ##STR3## (R.sup.5 denotes a hydrogen atom, --COC.sub.6 H.sub.5 or --Si(C.sub.6 H.sub.5).sub.2 C(CH.sub.3).sub.3) when R.sup.2 is --COOR.sup.4 (R.sup.4 denotes Na or a methyl group) or denotes --COOR.sup.4 when R.sup.2 is ##STR4## and a method of preparation thereof. The above novel compounds of present invention are useful as a tumor maker, a molecular marker for cells having the ability of differential induction, or an intermediate of the synthesis thereof. 'Y
