GSK812397

Description

GSK812397 is a CXCR4 antagonist with potential for the treatment of HIV infection. To evaluate the clinical potential of GSK812397, kilogram-scale agent candidates are needed. Here, an improved, scalable synthetic route for the CXCR4 antagonist GSK812397 is described. This new route has been scaled up in a 50-liter stationary facility to obtain 1.2 kg of agent substance in 20 % overall yield and >99 % chemical and enantiomeric purity in five steps. CXC chemokine receptor 4 CXCR4 is a 7-transmembrane protein that functions in part as a host co-receptor for multiple strains of HIV-1. It is thought that targeting CXCR4 will help inhibit the replication of several late cytopathic viruses; therefore, CXCR4 antagonists are one of the most promising new classes of experimental anti-HIV agents. GSK812397 is a potent CXCR4 antagonist and is therefore a candidate for investigation for the treatment of HIV infection.
