New PTA (1,3,5-triaza 7-phosphaadamantane) derivatives associating zwitterionic structure and coordinative ability
摘要:
The reactions of PTA (1,3,5-triaza 7-phosphaadamantane) and HMTA (1,3,5,7-tetraazaadamantane) with 1,3-propanesultone or 1,4-butanesultone gave the water soluble zwitterionic derivatives PTA(+) C3H6SO3 (1), PTA+ C4H8SO3 (2), HMTA(+) C3H6SO3 (3) and HMTA(+)C(4)H(8)SO(3) (4). The crystal structure of HMTA(+)C(3) H6SO3 is reported. The coordinative ability of 1-4 towards Pt(II) and Ru(II) has been investigated and the antiproliferative activity of ligands and complexes has been tested in two human ovarian cancer cell lines, A2780 and SKOV3.
