structure-activity studies related to the novel DNA-nonbinding adriamycin analogues N-(trifluoroacetyl)adriamycin 14-valerate (AD 32) and N-(trifluoroacetyl)adriamycin 14-O-hemiadipate (AD 143), we have now prepared a series of N-(trifluoroacetyl)adriamycin derivatives with N-acylamino acid esters at the 14-carbinol position. Target compounds were made by reaction of N-(trifluoroacetyl)-14-iododaunorubicin

H-1-NMR studies revealed that either the benzene or the naphthalene ring of 8-anilinonaphthalene-1-sulfonate (ANS) was accommodated by beta-cyclodextrin (beta-CyD) bearing an N-Ac-L-Leu residue, while beta-CyDs bearing an N-Ac-L-Ile and N-Ac-L-Val residues accommodated the naphthalene ring of ANS.
