Synthesis and antitumor activity of s -tetrazine derivatives
摘要:
Fifty-five compounds of s-tetrazine derivative including hexahydro-, 1,6-dihydro, 1,4-dihydro-, 1,2-dihydro- and aromatic s-tetrazine were prepared. Their antitumor activities were evaluated in vitro by MTT method for P-388 cell and SRB method for A-549 cell. The results show that there are 9 compounds which in 10(-6) muM have more than 50% inhibition rate to A-549 cancer cell growth, and 7 compounds in 10(-6) muM have more than 50% inhibition rate to P-388 cancer cell growth. The IC50 of compound 3q for P-388, Bel-7402, MCF-7 and A-549 are 0.6 muM, 0.6 muM, 0.5 muM and 0.7 muM, respectively. So s-tetrazine derivative is a kind of compound which possesses potential antitumor activities and is worth to research further. (C) 2003 Elsevier Ltd. All rights reserved.

The synthesis of a series of 3,6-disubstituted-1,2,4,5-tetrazines has been effected using an inverse electron demand [2 + 4] cycloaddition strategy. The crystalstructures of 18 members of this series of diazafluoranthenes are reported. Stereochemical analysis shows that diazafluoranthenes, substituted across the bay region, are helically-twisted strained aromatic molecules. The dihedral angle between

A series of new unsymmetrical 3-phenyl-6-benzyl-1,2,4,5-tetrazine derivatives 10a-i were synthesized and characterized by IR, NMR, MS, and element analysis. The structures of 4a, 10c, 10d and 10h were analyzed by X-ray crystallography, which had intermolecular C-H-N, C-H-Cl, C-H-II and II-II interactions.
