Abstract Background C-1027, produced by Streptomyces globisporus C-1027, is one of the most potent antitumoral agents. The biosynthetic gene cluster of C-1027, previously cloned and sequenced, contains at least three ... to investigate the role of sgcR3 in C-1027 biosynthesis. Results Overexpression of sgcR3 in S. globisporus C-1027 resulted in a 30–40% increase in C-1027 production. Consistent with this, disruption of sgcR3 abolished C-1027 production. Complementation of the sgcR3 -disrupted strain R3KO ...

Abstract The radiomimetic enediyne C-1027 induces almost exclusively DNA double-strand breaks (DSB) and is extremely cytotoxic. Unique among radiomimetics, ataxia-telangiectasia mutated (ATM) is dispensable for cellular responses to C-1027-induced DNA damage. This study explores the biological activity of three recently bioengineered C-1027 analogues: 7″-desmethyl-C-1027 (desmethyl), 20′-deschloro-C-1027 (deschloro), and 22′-deshydroxy-C-1027 (deshydroxy). Each compound maintains the characteristic ability of ...

We investigated the ability of TZT‐1027 (Soblidotin), a novel antimicrotubule agent, to induce antivascular effects, because most vascular targeting agents that selectively disrupt tumor vasculature also inhibit tubulin polymerization. Treatment with 10 −7 g/mL TZT‐1027 rapidly disrupted the microtubule cytoskeleton in human umbilical ... single intravenous administration of 2 mg/kg TZT‐1027 to mice bearing Colon26 tumors significantly reduced tumor ... administration, respectively. These results strongly suggest that TZT‐1027 possesses antivascular effects. TZT‐1027 induced apoptosis not ...
