Bone targeted drugs 2. synthesis of estrogens with hydroxyapatite affinity
摘要:
The utility of the bone targeting 4-carboxy-3-hydroxy-1,2-pyrazole heterocycle was tested by the synthesis of hybrids with the non-steroidal estrogen hexestrol. Compounds 1 and 2 demonstrated significant hydroxyapatite affinity, while maintaining weak estrogenic activity in whole cell assays. (C) 1996 Elsevier Science Ltd.
