The synthesis and anti-neoplastic activity of N2-isobutyryl-2'-deoxyguanosine-N7-cyanoborane derivatives.
Journal Article (Journal Article)
N2-Isobutyryl-2'-deoxyguanosine-N7-cyanoborane derivatives were observed to be potent antineoplastic agents and to be active against a number of human tissue culture tumor cells, e.g. Tmolt3 leukemia, HeLa-S3 uterine carcinoma. Selective agents were active against colon adenocarcinoma, osteosarcoma and glioma growth. These agents preferentially inhibited both DNA and RNA synthesis of L1210 cells. De novo synthesis of purines was significantly inhibited at the regulatory sites of PRPP amido transferase and IMP dehydrogenase. Other sites of inhibition were thymidylate synthetase, OMP decarboxylase and thymidine kinases. The agents also significantly reduced deoxyribonucleotide levels and caused DNA strand scission.
