Benzamide riboside, a recently discovered inhibitor of IMP dehydrogenase (IMPDH) exhibits oncolytic activity. IMPDH is the key enzyme of de novo guanylate biosynthesis and was shown to be linked with proliferation. Therefore, IMPDH is a very good target for antitumor therapy. In order to be active,

To explore novel histone deacetylase (HDACs) inhibitors with anti-tumor activity, MS-275, a HDACs inhibitor, was prepared and used as a lead compound to design new N-substituted benzamide derivatives. MS-275 and eleven target compounds were obtained, and their structures were confirmed by 1H NMR and

Differential radiosensitization of human tumour cells by 3-aminobenzamide and benzamide: inhibitors of poly(ADP-ribosylation).

Prihlásiť Registrácia

The effect of 3-aminobenzamide (3AB) and benzamide (BZ) (inhibitors of poly(ADP-ribose) synthetase) on radiosensitivity was investigated in normal human fibroblasts and three human cell lines established from tumours with varying degrees of clinical radiocurability. The human tumour cell lines

Benzamide riboside (BR), a synthetic C-nucleoside, acts as a strong growth inhibitor of cancer cells in vitro and in vivo. BR, like TR and related nucleoside prodrugs, act by anabolism to NAD analogs. These analogs selectively inhibit IMPDH, leading to depletion of cellular GTP, growth cessation,

Synthesis, radiosynthesis, and in vitro evaluation of [131I]-5-iodo-N-[2-(6,7-dimethoxy-3,4-dihydro-1H-isoquinoline-2-yl)-ethyl]-2-methoxy-benzamide as a potential tumor imaging agent.

Benzamide riboside (BR) is a novel anticancer agent exhibiting pronounced activity against several human tumor cell lines via the inhibition of inosine 5'-monophosphate dehydrogenase (IMPDH), thereby restricting the biosynthesis of guanylates. Although it has been demonstrated that BR inhibits IMPDH
