however , these mutants exhibited no cross-resistance to other cg derivatives , which either lacked the above groups ( viz . digitoxin , digitoxigenin , dihydrodigitoxin , digitoxigenin mono- and bisdigitoside , nerifolin , gitoxigenin , gitoxin , 16-acetylgitoxin , lanatosides a and b , cymarin , convallatoxin , oleandrin , strophanthidin , actodigin and bufalin ) or in which the 12 beta-oh group was acetylated ( viz . as in the case of 12-acetyldigoxin ) .
