Synthesis and anti-tumor activities of platinum(II) complexes of 1,2-diaminocyclohexane isomers and their related derivatives: Synthesis and anti-tumor activities of platinum(II) complexes of 1,2-diaminocyclohexane isomers and their related derivatives. Kidani, Y.; Inagaki, K.; Saito, R.; Tsukagoshi, S. (Nagoya City Univ., Nagoya, Japan). J. Clin. Hematol. Oncol., 7(1), 197-209 (English) 1977. CODEN: JCHODP. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacodynamics) Section cross-reference(s): 24 Pt(II) complexes with cis- [1436-59-5], d-trans [21436-03-3], and l-trans-1,2-diaminocyclohexane [20439-47-8] were prepd. and tested for antitumor activity. The Pt(II) complexes included the Cl, oxalate, malonate, and methylmalonate salts and the uracil complexes. The l-trans-1,2-diaminocyclohexane complexes showed the greatest neoplasm inhibiting activity. In contrast, complexes of Cu and Ni with 1,2-diaminocyclohexane were inactive. The conformational difference obsd. in this study may give very important information in the study of the mechanism of Pt complexes.

Intramolecular hydrogen bond self-template synthesis of some new Robson-type macrocyclic ligands: Intramolecular hydrogen bond self-template synthesis of some new Robson-type macrocyclic ligands. Wu, Jin Cai; Tang, Ning; Liu, Wei Sheng; Tan, Min Yu; Chan, Albert S. C. (Department of Chemistry, Lanzhou University, Lanzhou 730000, Peop. Rep. China). Chinese Chemical Letters, 12(9), 757-760 (English) 2001 Chinese Chemical Society. CODEN: CCLEE7. ISSN: 1001-8417. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 28 The intramol. hydrogen bond self-template effect was suggested in the process of directly synthesizing the first six chiral metal-free Robson-type macrocyclic ligands. These ligands were characterized by 1H NMR, IR, FAB-MS. The macrocyclic compds. were prepd. by cyclocondensation 2-hydroxy-5-methyl-1,3-benzenedicarboxaldehyde, 5-chloro-2-hydroxy-1,3-benzenedicarboxaldehyde and 5-(1,1-dimethylethyl)-2-hydroxy-1,3-benzenedicarboxaldehyde with (1R,2R)-1,2-cyclohexanediamine or (1R,2R)-1,2-diphenyl-1,2-ethanediamine, resp. The Robson-type macrocyclic ligands included derivs. of (4aR,13aR,17aR,,26aR)-1,2,3,4,4a,13a,14,15,16,17,17a,26a-dodeca hydro-7,,24-dimethenodibenzo[b,m][1,4,12,15]tetraazacyclodoco sine-27,28-diol and (4R,5R,15R,16R)-4,5,15,16-tetraphenyl-3,6,14,17-tetraazatricyclo[17.3 .1.18,12]tetracosa-1(23),2,6,8,10,12(24),13,17,19,21-decaene-23,24-di ol. Manganese, cobalt, nickel and copper complexes of these ligands were prepd. and chem. yields were reported.
