The complexes [(eta(5)-C5H4-CO-R)Mo(CO)(2)(eta(3)-C3H5)] [R = OH (1), Phe OMe (2)] have been examined as guests for the cyclodextrin (CD) hosts beta-CD and heptakis(2,3,6-tri-O-methyl)-beta-CD (TRIMEB), and the resultant inclusion compounds have been characterised in the solid state by elemental and thermogravimetric analyses, powder X-ray diffraction, C-13{H-1) cross-polarisation (CP) magic angle spinning (MAS) NM R spectroscopy and ITTIR spectroscopy. Singlecrystal X-ray analysis of 1 shows that the unit cell contains centrosymmetric supramolecular dimers comprising two di- carlx)nyl complexes linked through hydrogen-bonding interactions involving the carboxylic acid groups. In screening tests for antiproliferative effects, the Cl) adducts containing 1 displayed enhanced antitumour activity against mouse melanoma (when compared with nonincluded 1), while showing minimal activity towards human adenocarcinoma and nontumour rat myoblast cell lines. TRIMEB encapsulation resulted in a predominant toxic effect on tumour cells versus the rion-neoplastic rriyoblasl cells. |
