1. A 5,5-diphenylhydantoin compound having the structural formula: ##STR12## wherein each R is independently selected from the group consisting of hydrogen and
--CH(R.sub.1)--O--P(O)(OH).sub.2, wherein R.sub.1 is selected from the group consisting of hydrogen and C.sub.1 -C.sub.7 straight or branched chain alkyl; with the proviso that the R's cannot simultaneously be hydrogen; or the pharmaceutically
acceptable acid addition or basic salts, C.sub.1 -C.sub.4 alkylhalide quaternary salts or N-oxide thereof.
2. The compound as defined by claim 1, wherein either R is hydrogen, with the other being --CH(R.sub.1)--O--P(O)(OH).sub.2.
3. The compound as defined by claim 1, same being 3-phosphoryloxymethyl-5,5-diphenylhydantoin.
