In vivo and in vitro effectivity of some platinum complexes

The following platinum complexes have been tested: cis-DDP--cis-diamminedichloroplatinum(II), Platinex--1,2-diaminocyclohexaneplatinum(II)citrate, Platuran--1,2-diaminocyclohexaneplatinum(II)-glucarate , TMA--1,2-diaminocyclohexaneplatinum(II)-4-carboxyphthalate,o xo-PT--cis-diamminedichloro-trans-dihydroxyplatinum(IV), CHIP--cis-dichloro-bis-(isopropylamine)-trans-dihydroxyplatinum(IV ), CBDCA--cis-diammine-cyclobutane-1,1-dicarboxylatoplatinum(II ). The activity of all tested complexes againt L1210 cells was higher in soft agar colony assay when compared with suspension culture of the same target cells. Using various doses and schedules oxo-Pt, CBDCA and cis-DDP exhibited the highest in vivo activity against P388 leukemia.
