  • Patent number: 6096874
    Abstract: The synthesis of tamoxifen derivatives, most particularly halo, halo alkyl, hydroxy, and amino tamoxifen derivatives is disclosed. The native tamoxifen molecule includes a substituted chemical group positioned on the aliphatic chain of the tamoxifen molecule. Particular tamoxifen derivatives of the invention include chloro, bromo, iodo, fluoro, amino and DTPA tamoxifen derivatives, and corresponding lower alkyl halogenated forms. The halogenated tamoxifen derivatives possess superior binding affinities for estrogen receptor rich tissues, such as uterine tissue and breast tissue, relative to unsubstituted native tamoxifen. Radiolabeled forms of the tamoxifen derivatives may be used as highly specific imaging agents for estrogen receptor rich tissues. The fluoro and bromo tamoxifen derivatives are particularly useful for imaging estrogen receptors by PET whereas the iodinated tamoxifens are particularly useful in imaging estrogen receptors by SPECT.

  • Patent number: 4259257
    Abstract: The invention relates to novel 1-phenyl-2-amino-1,3-propanediol-N-alkyl derivatives having the general formula I ##STR1## wherein R.sub.1 is hydrogen, alkyl having from 1 to 8 carbon atoms or phenoxymethyl, andR.sub.2 is hydrogen, alkyl having from 1 to 8 carbon atoms or 2,2-diphenylethyl,with the proviso that if R.sub.1 is phenoxymethyl then R.sub.2 may stand only for methyl, and if R.sub.2 is 2,2-diphenylethyl then R.sub.1 may stand only for hydrogen, and its isomers and pharmaceutically acceptable salts. Furthermore, the invention relates to a process for preparing these compounds.The novel 1-phenyl-2-amino-1,3-propanediol-N-alkyl derivatives having the general formula I possess significant anti-anginose activity and show several other biological activities.
