Author(s): Tien N. Banh, Nageswara R. Kode, Shashikan Phadtare.

Abstract:

The five dose comparative CNS Cancer Cell Line cytotoxicity profiles of N9-[4'-Chloro-2'-butynyl-1'-yl]-2,6- dichloropurine 1, Bis- 6,9-[4'-chloro-2'-butynyl-1'-yl]-thioguanine 2, Bis- 6,9-[4'-chloro-2'-butynyl-1'-yl]-mercaptopurine 3, Bis-6,9-[[o-(chloromethyl)phenyl]methyl]-thioguanine 4, Bis-6,9-[[o-(chloromethyl)phenyl]methyl]-mercaptopurine 5, 6-[4'-chloro-2'-butynyl-1'-yl]-thioguanine 6, and N9-[4'-Chloro-2'-butynyl-1'-yl]-6-(4-methoxyphenyl)purine 7 are presented in this communication. These compounds were evaluated for cytotoxic activity against NCI-60 DTP human tumor cell line five dose screen. All the unsaturated highly lipophilic substituents as expected contributed for the excellent CNS cancer cell line cytotoxicity, GI50 values 4-7 μM. Further, the thioguanine, mercaptopurine, and 6-phenylpurine are identified as the potential candidates for the CNS active cancer drug development and to cross the blood brain barrier.
