The synthesis and biological activities of the platinum complexes of 2-aminomethylaziridine, 2-aminomethylazetidine, 2-aminomethylpyrrolidine, 2-aminomethylpiperidine as carrier ligands are described. The platinum complexes of 2-aminomethylazetidine and 2-aminomethylpyrrolidine are significantly effective against murine tumors. In particular, 2-aminomethylazetidine (1,1-cyclobutanedicarboxylato)platinum II (13) and 2-aminomethylpyrrolidine(1,1-cyclobutanedicarboxylato)platin um II (16) exhibited potent antitumor activity and were soluble in water, and their antitumor activities against Colon 26 carcinoma (sc-ip system) were superior to CBDCA and comparable to CDDP.

D008024 Ligands A molecule that binds to another molecule, used especially to refer to a small molecule that binds specifically to a larger molecule, e.g., an antigen binding to an antibody, a hormone or neurotransmitter binding to a receptor, or a substrate or allosteric effector binding to an enzyme. Ligands are also molecules that donate or accept a pair of electrons to form a coordinate covalent bond with the central metal atom of a coordination complex. (From Dorland, 27th ed) Ligand

D004337 Drug Carriers Forms to which substances are incorporated to improve the delivery and the effectiveness of drugs. Drug carriers are used in drug-delivery systems such as the controlled-release technology to prolong in vivo drug actions, decrease drug metabolism, and reduce drug toxicity. Carriers are also used in designs to increase the effectiveness of drug delivery to the target sites of pharmacological actions. Liposomes, albumin microspheres, soluble synthetic polymers, DNA complexes, protein-drug conjugates, and carrier erythrocytes among others have been employed as biodegradable drug carriers. Drug Carrier
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
