N(11)-diethyl-2,10-dihydroxynorspermine [(2S,10S)-(HO)(2)DENSPM] at 96 h. Both cyclopropyl compounds reduced putrescine and spermidine pools, but less effectively than did DENSPM and its derivatives. Only CPMENSPM, and not (2R,10S)-(HO)(2)CPMENSPM, lowered spermine pools. As with DENSPM and (2R,10R)-(HO)(2)DENSPM, both cyclopropyl analogues diminished ornithine decarboxylase and S-adenosylmethionine decarboxylase
